I used verygreen's size-agnostic installer with my 8GB SD card, and put CM7-107 nightly on it.
I ended up with the boot partition of about 100MB, two android partitions (one 450MB, the other 1GB), and the rest being "sdcard", around 6GB as FAT32.
I'd really like to take the 1GB android partition (my system stuff, and where apps are installed) and kick it up a bit in size, taking space away from the SDCARD partition. That way i have more room for app installs, etc.
I tried using EASUS Partition Manager, and while it'll let me take space away from the SDCARD/FAT32 partition, it's not letting me give it to any of the "other" (linux/android) partitions - doesn't give me an option to resize it, once I have unallocated space available on the SD card.
Any ideas? This is Windows 7 64bit, btw.
Please forgive me for reposting this but I cannot find the answer and it's driving me crazy.
I am running a dual boot HTC HD2 with Windows Mobile 7 in NAND and Android on the SD card.
Windows Mobile 7 creates a dedicated and non-standard partition on the back half of the card.
Android is booting from a FAT-32 partition on the front of the card.
The partition table looks something like this for the 16GB Class 10 card I am using:
FAT-32 Partition from 0 to approx 7.3 GB set as primary.
Type 4 Partition from 7.3GB to the end of the card.
When running Android from a dedicated SD card the SD card can be found at /mnt/sdcard and everthing is hunky dorey.
However, when the Windows 7 partition is also on the card /mnt/sdcard is empty (there is nothing mounted there). All of the applications that look for an SD card cannot find it. I did find the entire contents of the SD card in /bootsdcard.
I tried creating a soft link between from /bootsdcard to /mnt/sdcard and that did not work.
Does anybody have any ideas how to fix this?
Thanks,
Mike

That is exactly the procedure I followed to get the dual boot to work at all on 1 SD card. That is how I got the two partitions.
Android boots from the SD card and works (I am using it every day). Android just doesn't think that there is an SD card installed for A2SD or any other SD card function.
Should I reduce the size of the FAT-32 partition and create another FAT-32 or EXT partition?
Help please, this is driving me crazy.
You have to start all over. Just save your data on both OS's. You should have only 2 partitions in the end FAT 32 for android and Other for Window 7. Make sure that Window 7 partition has a larger partition size than android, otherwise you will have a lot of errors. Hope this helps you out. J
I've done that twice. Everything works in Windows 7 the only issue is for some reason Android doesn't see the SD card that it is booting from.
What SD card are you using? I am using 32g Sandisk Class2. Everything works perfect on mine with the HD2. Perhaps it's the SD Card?

The card works fine for Windows 7 with or without the Android FAT-32 partition.
If the FAT-32 partition is the only partition on the card then Android sees the card correctly.
With both partitions Android (MCCMBoxmax V8.0) boots and runs from the card just fine with the exception that Android doesn't see the SD card that is was booted from. However, the card is mounted on /bootsdcard.
I even tried splitting the FAT-32 partition into a smaller FAT-32 partition and an EXT2 partition. That also did not work.
I have tried the following cards:
Samsung 16 GB Class 2 - MMB3R16GUACA-GE (replacement supplied by HTC)
Patriot 16 GB class 10 - PSFGMCSDHD10-BC
And like I said, both OS's work except for this one android glitch.
same problem for me...
Same problem for me too!
Additional info:
If i browse back to /sdcard i can see everything on my memory card. But there is nothing on /mnt/sdcard
Any help suggestions are much appreciated...

I had exact same issue on my previous dual boot setup on various cards and various roms. Prior to this I had no problems setting up a dual boot with WP/Android.
Okay, so this is probably not helpful, since I am very limited in my understanding, but others out there chime in if you know... I may be wrong but it seems that back when we only had Windows Mobile 6.5 with the ability to run Android from the sd card, it seems that there was this same limitation. I think that it is the case, because I remember in January when the ability to run Android from NAND first was released, I was all excited because we would finally be able to use our SD cards in Android correctly. In summary, I think it is due to running Android from SD... it doesn't recognize the SD card as an sd card because it treats it like the internal memory. Someone correct me if I am wrong, but I seem to remember that.

However, the SD card works properly if there isn't a Windows Mobile 7 partition even when booting from the SD card.
Something about the Windows partition is messing up with the mounting of the SD card. I just don't know enough to figure it out.
load up a partition program and make sure both partitions are set to primary.

I installed WM7 on NAND, and Android 2.3.4 on SD Card. I followed the original steps as mentioned in this thread above, and have run into the same issue. That is, android is not able to recognize the SD Card. Now, my question is that can I just format (and delete) the first half of the sd card (the one that has android) .. and then create one Fat-32 and one ext-2 partition on that .. Will that work? I am trying to understand if I need to upset my windows installation at all ..
Also, I need to understand the role of Partition 1 and partition 2 above. I was of the understanding that the "Android" folder (ROM Files) should be loaded to the Fat32 partition. However, in this case it seems that the ROM files are kept in ext2 partition instead?
Thanks in advance, for your help
Can't get WP7 partitions created on reset
I have the US T-mobile HD2 loaded with WP7 7592 Green Mango with market place ROM and it runs fine on a 2GB Samsung card. I also have a class 4 Adata 32 GB card that I have a 14.4 GB FAT32 partition created for Android, and that runs without issue.

The main issue is that when I have tried doing the phone reset on WP7 NAND it doesn't seem to create the necessary partitions on the 32 GB card any way I try, and I've tried loading WP7 ROM with the 32GB card in the phone. But whenever I boot up WP7 with the 32GB card in the phone it says: storage card not working, so I boot up with 2GB card in phone, select reset and right before I click the the last confirmation I switch the cards, but after going into Magldr on boot up and putting card into PC the new partitions haven't been created. I also tried splitting the last part of the drive into a 203 MB Fat 16 drive located just right of FAT32 partition and then creating unformatted partition with remaining space. I have 2 card readers and 2 2GB cards and the 32GB card. Please tell me what I should try next. Thanks so much!

if i have read this right, this is not a dual boot problem, but a "I can't get WP7 to work with my 32GB sd card" problem.
It may be your card is not compatible with WP7
32 GB WP7 Compatible Cards
I guess that's right, but I have looked through posts and not found any list of 32GB class 4 or higher cards that are compatible. It seems that a lot of people are recommending sandisk cards. If that is the brand I need to go with I can. Thanks for the correction.
I am running CM7 on a 16GB Sandisk Class 4 uSD. I'm very new to this, so I hope someone can help me with my question. When I download apps from Google Play, where does it get stored? When I go to Settings -> Storage, I see the following: SD card/Total Space = 13.31 GB, SD card/Available space = 13.22 GB. Under Internal storage/Total space = 0.93GB, Internal storage/Available space = 680 MB. Under Additional storage: /mnt/emmc Total space = 1.0GB, Additional storage: /mnt/emmc Available space 1.0GB.
So it looks like the apps are being stored in "Internal storage", but I'm not sure whether that is in NC's internal memory, or the SD card. On the one hand, the SD card shows 13.22 GB available out of 13.31 GB, so it looks like it is not being used. But on the other hand, Additional storage: /mnt/emmc Available space is 1.0 GB, so I assume that is my 1.0 GB allotted to me by B&N, so it also doesn't look like I'm using up the NC's internal memory.
So where are my apps being stored? If they are not being stored on the SD card, how can I move the existing apps to the SD card, and also how do I set it up so that all apps (and book) downloads go to the SD card in the future?
Your apps are running on your SD card's "internal" partition which is still on the SD card.

Size of Internal Storage?
If Internal storage is on the SD card, why is it only 0.93 GB? Shouldn't it be (in the case of a 16GB card) 13 GB? How can I use the 13 GB that is left on my SD card?

In CM terms, internal storage means your /data partition. For SD installed CM, your /data is still on your SD, just in a separate partition. And when play store installs an app, it installs the application files to your /data partition on the SD.
When your SD was first set up, several partitions were created on it, one of which was /data. The size for the /data partition was set when your SD was partitioned. This partitioning is why your 16GB looks like it now only has 13GB. Some of the space was set aside for other uses.
The 13GB is your media partition on the SD. It is named 'sdcard' in CM terms. It is to be used for your media files, books, movies, pictures, etc. And installed apps use it to store any files they need to (like files they download, etc.).

Re-sizing Partitions
j8048188 and leapinlar, thanks for explaining to this noobie where apps are stored. Is it possible to re-size the /data and /sdcard partitions, to say, 3GB and 11GB, without wiping out the apps I already downloaded? If so, how could I do it?

Unfortunately, no, not with Windows and not once you have installed a ROM and there is information stored in /data. Windows does not know how to read the data format that /data uses. Windows based partition managers can manipulate the /data partition if there is no data in it. And the only time that is true is just after you have booted the new SD, but before you have installed your first ROM. (However, if you have Linux, you can use partition manager software there to resize with data in it since Linux knows how to read the data).
So if you have Windows and you want it set bigger, you have to catch it before you install your first ROM on it. You can back up your installed apps with titanium backup, start over with your SD again, manipulate the partitions before installing the ROM and restore your apps later. If you decide to do that, use Mini-Tool Partition Manager and make partition 4 (media) smaller and partition 3 (data) larger. Be sure to copy the titanium backup files to your PC because they will be wiped out if you start over.

In ubuntu, use gparted to resize the partitions on the sd. Shrink partition 4 (leaving space in front of it) and expand partition 3 to fill it. And usually people say 2GB is large enough for partition 3. If you find later it is not big enough, just do this again.

Hi! Successfully rooted my Nook ST using Nook Manager, except I used a 32 GB micro SD card to do the rooting. After rooting, I ended up with two partitions on the SD card, Nook (239 MB) and Nook Manager (62.9 MB). I was wondering what I need to do to be able to utilize the rest of the space on the card? The reason I bought a 32 GB card was so I could store all my sideloaded books there, and now I find I'm just limited to the space/partitions showing up when I connect the nook via USB.
You need to repartition your card.
Partition Magic can do that.
If you want to use multiple partitions on the SD card (like 2 x 16 GB) you might want to look at:

Thanks, will download a copy of Partition Magic later. I really am completely clueless when it comes to programming though. In fact, I'm only here because the folks at mobileread told me I'd probably have better luck having my question/s answered here than there. So just to confirm, I can repartition the drive using partition magic so I'll have one extra partition for the books I want to sideload, and I'm good to go already when I re-insert the SD card into the Nook? Or do I have to attempt the code that you gave in the thread you linked?
If you want to have a single FAT partition on your SD card you can do that without much change.
It comes down to whether you want to be able to pull the SD card and plug it into random desktops and things.
If you want to have multiple partitions or ext3 partitions you will have to use the new vold in the link above.
if used windows 7,8. Insert a memory card into the card reader. Go to cmd(administrator mode) and run command:
Diskpart
List Disk
Select Disk 1 (#select sdcard)
clean (#clean partition sdcard)
create partition primary
active
format fs=fat32 quick
assign (#run command if not view sdcard in mycomputer )
Renate, I tried to repartition my SD card, but got a "disk is not formatted, do you want to format it now?" message. So I had no choice but to do a data recovery using EaseUs Partition Master first, then went ahead and clicked format now. Then I tried using Minitool Partition Wizard (couldn't find a free version of Partition Magic) to create new partitions in the formatted SD card so that the NookManager partition would be larger (27 GB) while the NookBackup partition would be 2 GB. Except that I can't seem to create any new partitions at all. And I also have no idea how to restore the data I'd backed up earlier either.
Sorry, I missed seeing this come up when you posted it.
When your Nook asks you if you want to format you should say "No!".
It could be that it misidentified the situation.
In any case, you want to look closer before formatting anything.
Here's a gotcha.
If you are using ext3 and the internal clock has reset itself then the last mount will be in the future.
That makes things angry. Check that the date/time on the Nook is correct.
You can use gparted to give the card the partition layout you need (i.e. first NookManager partition is big, second NookBackup partition is only large enough to hold a backup), then write the first partition from NookManager.img into first partition of the card (you need to do something roughly similar to this. Then you can use gparted to set the "boot" flag on the first partition and use the card to backup&root your Nook. Then remove the "boot" flag, and keep using the card for storage (it's a bit messy to have both user&app files AND NookManager boot files in the same place, but if you only have one card, then this is inevitable - i haven't found a way to mount the second or the third partitions from the card). The card will act as normal storage device when flag is not set, and as NookManager bootable card when flag is set.
I'm using a 400GB SD card. I saw a comment about creating 2 different partitions on it as I want to use part of it for app storage and the other part for file storage, The second partition would be exFAT so I can remove the card and transfer my books, music, etc. to it by attaching the SD card to my laptop as I understand that Windows would not be able to recognize the partition that would be formatted as internal storage. I did format the SD card using my laptop as two separate partitions. My Samsung Galaxy Tab A saw both partitions. I selected the 96GB partition as I wanted to use that for app storage and selected the option to use it as internal storage. Unfortunately when I did that, it appears that the system set the whole CD card up for internal storage. Does anyone have any insight on how to accomplish this - use part of the SD card for internal storage and part of it for storage that would be recognizable by Windows? Thank you very much.
I have not tried, so take the advice as a suggestion, perhaps android can be "fooled", which I doubt.
After creating a bulk partition in android, move the SD to Windows and resize that partition, and create a second partition on the remaining capacity and hide it.
Now move the SD back to android and see what happens.
If android will reformat the partitions again then I can't advise anything else.
However, if android accepts the memory, then the next step is to discover the partition in Windows and recheck the SD in android.

Well, I was trying to work on that and now the Android Storage module (in Settings) keeps crashing when I open it. IDK what happened here. I've reformatted the SD card, I've removed the SD card, I've rebooted the table multiple times. I'm almost to the point of having to restore the tablet from scratch ... again.

You're trying to convert a partition in sd card as internal storage and leave the rest as an external storage. Not possible as far as I know.

Thats a bummer but that is what I was feeling was going to be the outcome. I guess I'll just go with it as internal storage then and be rlefated to wireless transfer of my books, etc. To the tablet. Any thoughts on why my Storage module keeps crashing now? Something definitely went nuts somewhere along the way here. It was running fine.. until I start poking around with this. I'll probably just do a rebuild again tonight.. if I can find my steps notes.
I also don't think it's possible to do what you have in mind. It's also important to remember that Windows will only mount the first partition of an SD card. It won't see any other partitions without 3rd party software installed.

The reason people want a micro SD card is to be able to move it around between devices, so it is not a good idea to convert it into 'internal storage' for two reasons:
1. You can no longer move the card around (not without reformatting it again).
2. This process would significantly slow down the system if the OS starts saving apps, data and files on the micro SD card because it sees this space as internal storage.
Because of how you partitioned the SD card and tried converting only a part of it as internal storage, my guess is the process caused corruption somewhere, and the system is crashing because of that. I'm afraid you'll have to do a factory reset and start from scratch. I hope your files are safe.

I'm using a 400GB SD card. I saw a comment about creating 2 different partitions on it as I want to use part of it for app storage and the other part for file storage, The second partition would be exFAT so I can remove the card and transfer my books, music, etc. to it by attaching the SD card to my laptop as I understand that Windows would not be able to recognize the partition that would be formatted as internal storage. I did format the SD card using my laptop as two separate partitions. My Samsung Galaxy Tab A saw both partitions. I selected the 96GB partition as I wanted to use that for app storage and selected the option to use it as internal storage. Unfortunately when I did that, it appears that the system set the whole CD card up for internal storage. Does anyone have any insight on how to accomplish this - use part of the SD card for internal storage and part of it for storage that would be recognizable by Windows? Thank you very much.

You should NEVER use an SD card for internal storage. They are MUCH to slow for that purpose. Today's SoC have RAM chips mounted directly on top and are several times faster than the fastest SD card bus. And low end tablets, which includes ALL Tab A devices, use a USB bus with limited bandwidth. So using faster SD cards is pointless as they will still only be as fast as the bus. SD cards are fine for storing video, audio, text and downloaded files, but NOT for running apps. Doing so will cause the device to be laggy at best, and cause crashes at worst.

The two partitions on the USB flash drive can be seen* in Windows without third-party software.
*I don't have an English Windows interface.

I meant that it won't mount the second partition, although you can see it in Disk Manager.

Windows 10 mounts both of these partitions, assigns them letters and you can use them (read and write).

I stand corrected! Previous versions of Windows could not do that.

Something strange in that attachment. Since when do Android SD cards have NTFS partitions? As far as I know, the internal storage partitions that Windows couldn't read were formated as Ext3 or Ext4 and the external as either FAT32 or exFAT.

Don't suggest the volume label. Partition K: is FAT. The example shows that Windows can show two partitions on a USB stick.

Of course it can. It can show several. But NOT the two partitions created on an Android SD card because one of then is formated in a file system Windows doesn't recognize and that is what the poster was talking about.
edit: Disk Manager will actually show the partition but it won't be assigned a drive letter because Windows can't mount it.
