As of now I've got CM7 latest nightly installed on my eMMC which works fine.
However I have a certain interest in installing Nookbuntu on my SD Card.
My first question at hand is... if I've got a bootable SD-Card in my Nook, can I still boot into the eMMC installed system without removing the SD-Card?
Maybe via a certain button combination on boot?
I'm asking this because my Nook is in a leather case and it would be troublesome to remove it every time to boot into Android, then put the SD Card back in and stick it back into it's case.
My second question is about the USB Mounting via Android, from what I know a bootable SD-Card for Nook consists of several partitions...
Do all partitions get mounted into Android when I boot it with a Nookbuntu SD Card inside? Which partition will get mounted to /mnt/sdcard?
And what happens if I USB-Mount it via USB Cable to my PC as Mass Storage?
I only have one (rather big) 32GB MicroSD Card, and would like to limit myself to just this card to operate both Ubuntu and Android...
So I prefer asking in advance before doing something I will regret.

Much help would be appreciated. Total new experience for me.
I have cm7 stable on sd of my nook color. I have everything up and running great. trying to overclock and when I take my sd card out of nook and put into laptop, it asks me to format it. It is not allowing me to copy the kernal to my sd card. Is there another way of doing this?
While inserted in my laptop, I look at the properties of the sd card and it is showing to be in raw format.
any help would be greatly appreciated.
Are you unmounting the SD card before you eject it? Also, are you sure the FS on your SD is FAT32?
When I originally formatted the card before I burned the installer and the cm file on the card it was formatted to a fat16.
I have not unmounted the card prior to ejecting. I will give that a try.
okay I unmounted before ejecting... put into laptop and the laptop is still wanting to format the card.
when I look at the properties it says file system is raw, and storage space is 0mb.
Maybe your card reader couldn't read microSDHC card?
With CM7 running off a uSD which I am doing as well, some built in laptop readers will not read the uSD but it may be read with a USB reader. But, it will typically only read the 1st partition which is the Boot partition (unless you use a program to set the 4th partition as primary and active).
To access the 4th partition for storage, you can try to connect the Nook by USB cable to your computer and enable USB storage mode. That should connect you to the 4th partition and your internal mmc storage partition too.
If not, download and use the following app:

The app is a little deceiving, you have to scroll in the app to see the "Confirm" button when you are mounting, and unmounting.
Thank you!!! I'm going to try that tomorrow.
If you still have stock on eMMC, boot with the card out, then insert it before the stock OS fully loads (like on "n" or "Nook Color" splash screens). The NC will mount the boot partition as storage; there should be an SD-icon notification in the lower left, and if you tap it, it should say "SD card inserted." You can then connect via USB, and hopefully your card and PC will kiss and make up.
ETA: I've had no luck inserting the card after the OS is fully loaded--it just reads "SD safe to remove."
That worked!!! Thank you very much!!!
So i have Typhoon CyanogenMod7 (MAGLDR) running like a wet dream on my HD2, but the 2gb SD card is really a pain. So i found an 8gb from my Aino.
I have still not quite wrapped my head around how exactly everything is done, i get lost with all the partitions.
ANYWAY what i want is to use the new card without losing anything. What do i haveto do?
(My reply could take a while, so thanks in advance [really thanks])
boot into CWM, backups/restore, take a backup.
connect phone to PC, use CWM, enter mounts/storage, mount USB,
on the pc, copy off all the files found in the drive that shows up (thats the FAT32 partition)
((or use external card reader if you have one and prefer to do so, or from within running android, doesnt matter))
swap out sd cards,
again in CWM, advanced - partition sd card
re-mount USB, copy back on the FAT32 stuff
in CWM backup / restore, choose restore - advanced - restore sd-ext
restart phone, should work as if nothing happened.
Thanks a mil
I have a nook color with dual boot from sd card. The sd card having an android 3.0 version.
After I got the 1.4.1 update, I noticed that I was able to access the sd card( the boot partition alone) from the stock OS boot of nook.
But now, dont know how, I dont see that anymore.
Was this a flawed update that was fixed or am I missing something.
Do help please.
I could really use the advantage of using the bootable sd card as a regular storage card when using the stock OS of nook. I prefer reading on the stock OS of nook.
Not sure why you're not seeing the SD card anymore, does it still boot?
SD card installs create multiple partitions on the SD card and the Nook will only be able to access the first one (boot). It should be accessible with any version of the Nook default OS.
You should have a media partition with a decent amount of room (1-5gb depending on NC version). That would give you more room than the 100-or-so mb on the boot partition.
Just found out that you can point the emmc install to see the "sdcard" partition of the sd card using the following info:

use root explorer and edit vold.fstab to "4" instead of "auto" for sdcard mount

Yes, I can boot from it. Every time I plug in the SD card, the notification already says that it is safe to remove the SD card. In the device Info part of the setting, the "Unmount SD card" is already greyed, though it does say that the SD card is found.
It is however useful for me to know that the boot partition should always be accessible.
I did remove the SD card a couple of times without unmounting it first, could this possibly have corrupted the card?

Try to boot the uSD card (the one with Android 3.0 on it) and see what happens.
If it can, then it's good, if not, you can say it's corrupted.
Yes, I can boot from it. So I assume the card is OK
I plugged in other uSD cards and they get recognized fine. So I assume the Nook stock OS device recognition is OK.
I should probably recreate the boot partition as a last ditch effort
I had the same problem at first, but now I have mounted the correct sdcard partition that I wanted to mount.
I couldn't get it to work with editing the vold.fstab file at first. Then at some point after I manually mounted the correct partition through adb shell and edited the vold.fstab it now works.
I dont remove the SD card throughout the whole process of formating, imaging, and copying files over to it while it is in the Nook for installing CM7/CM9. I boot to internal Nook software and format the card through the Nook. Then I image it with the appropriate image. I resize it if necessary and copy the installation files over to it and then restart it. I do this because I have had problems unmounting it in the PC and then remounting it again to put files on it from the PC. If you need to add files to the boot parition later on, I just reboot to internal Nook and mount the SD card on PC through Nook software. Works great for me since I hated taking the card out all the time.
Yesterday I installed CM9 to a bootable sd card and my 2 biggest problems with this setup are: can't seem to get a usb hookup to a Windows PC working for either boot or sdcard, and can't get Adobe Flash to work. Anyone else?

Flash does not work yet on CM9. Dunno about the USB..I don't use it.
I am using a recent ICS nightly and have the same problem. It worked on an earlier install so this may be something with the current nightly. One work around is just to boot into stock nook and then connect.
So I am running CM7 off of an sd card in my nook color.(Using http://forum.xda-developers.com/showthread.php?t=1904129 and I highly recommend). Win32discimager for some reason created a small partition just larger than the installer which remains on the card. I also have the android OS on the card that is taking up 1 gb partition. The rest of my 16gb micro sd card is labeled as the emmc for the tablet which is not what i intended. Now I cant load it up with my movies and videos like I had hoped.
Does anyone know:
Is there any way I can change these partitions on my card? (I have already tried EasuUS partition manager)
Where did the 1gb partition that android is on come from and why did the emmc get so large?
Is there any way to take the android image currently on my sd card and just putting onto the nook after I have already had it run from the sd card and then just formatting my sd card for storage?
There are probably newbie questions but I have tried to do my own research and havent found any certainties. Any help would be really appreciated.

Ok, first you need to go to my tips thread linked in my signature and read in section B how the verygreen SD works. You will understand the partition structure a little better.
Now for your sdcard/emmc media storage problem, you have a setting wrong in CM7. Go to settings, CyanogenMod settings, Application and uncheck "Use internal storage". What that setting does is swap emmc and sdcard so that your real sdcard is called emmc and internal media storage is called sdcard. It is not default that way. Somehow it got checked.
