I was just re-imaging WP7 on my HD2 and noticed that when the magldr is loading, it runs something that says:
Boot Android from SD
Android Load at 18000000
From MicroSD
Load zImage
K:\ zImage
SD Kernal Open Failed
I am wondering if this could possibly be what is causing the sd card errors so many people including my self are getting. It would be nice to know if someone who is not having any issues with WP7 saw the same message upon first boot of magldr.
I think I have the same problem
all that means is MAGLDR is trying to read the android kernel from the SD card, but, boviously, it's not there, unless you're dual-booting

Hey, you know that you have to edit sth in your android build? You can't just copy an sd build and boot it with magldr...
This thread is a good intro:

Hi,
I have a question which need some advise. I am currently dual booting wp7 and android sd build. I use magldr to select boot from sd whenever i wanna use android. Btw, I swap btw 2 sd cards, 8gb each , one for wp7 and one for android.
I happened to find a spare sd card 8gb class 4 and thought would like to replace the android sd card which is only class 2, in hope of faster speed. I copied all the files from old sd card to the new class 4 and tries to boot via magldr as usual. However, i encounter this error which says kernel sd fails and thus cant boot. I insert old card back and it boots as normal.
So my question is does magldr recognises the new sd card and thus do not allow me to boot with the new sd card? Anyone knows and can advise ? Thanks
Btw, using mdj hd4.6 w/ wp7. 2.25 radio and magldr 1.12. thanks !!!

did you try to change the android build path in boot settings with this new card?
The setting for android path shld still be same since didn't change the path.
Anyway, I solve the problem. Have to full format the card. Thanks man
Sent from my HTC HD2 using XDA App
I have nand wp7 and sd android, partition the tf, two partitions 12GB fat32 for android, 2GB for wp7(unformatted fat16). The magldr can't recognize my card(I can not set the android folder and find this problem). I find a way to solve: take out the card and then push into phone again when in the magldr. But this way makes me crazy because everytime I restart the phone I must do the thing above again or I can't use the card in wp7 even can't boot the sd android.
Can someone help me to avoid this, thx first
Hello guys.
I have a HTC HD2 running Windows Phone 7 (on MagLdr 1.2).
I want to DualBoot Android AND WPH. Ive watched a tut on YouTube: http://www.youtube.com/watch?v=JTHRAUHZHlo
I did exactly the same and after that i took this Android DesireHD Built: http://forum.xda-developers.com/showthread.php?t=881937
It worked fine but android said, that there isnt a sd card in the device. Of course it is, cuz android boots from the sd card. When i remove my sd card, android freezes (of course). I tried to restart and i put the 512 MB data.img in the folder but there was the same problem again..
I tried it with an other card and i pushed the button "mount sd card"
and than it said "u can take out the sd card now" (or something like that)
Plz help me!
I am having the exact same problem. Have you found the problem/solution to it.
thanks.
you both update you magldr that should fix your issues.
so get newest radio, than flsh magldr 1.3
before you update make a complete backup!!
hope you both have the right partition layout on sd card.
(first partition must be fat32 second ext3 or ext4)
hope this helps.
for tut look at forums or pm me!!
Can someone describe the exact steps that are required to mount the SD card when the Android build is being run off the SD card using MAGLDR.

They are running Android from their SD card. It is not going to show a SD card being in the device because Android thinks the SD card is the device......

This will not help them at all, MAGLDR just serves as the bootloader for Android not the OS.
Allso you can not remove your SD card will booted into Android if you are using a SD card build it is running of the SD card not NAND.

So basically I cannot mount the SD card, no matter how it is formatted ?
I totally have this same problem. Neither WP7 or Droid will read the 16 GB card I'm using to run Droid. I think I'm using the DesireHD build also, maybe its that? I can probably see if changing it makes a difference.
I have the same problem. First time i installed WP7 and android, everything was working fine. Then i had to reset WP7 because it kept freezing, i followed the same steps again to dual boot with android and it booted fine but SD CARD is not mounted for some reason. I have tried 3 different android builds with same problem. Any help or tutorials?

This happened to me too with two SD cards. What I did was I run the Partition SD Card from AD Recovery. I forgot the partition layout, just find something that works for you. I was surprised that it has successfully created a partition...this erased everything so I needed to re-copy ROM files to SD card via Card Reader on my PC.
When I did it over, It finally worked. Am now running Sensation XL ROM.

Hello there,
I have a HD2 with NAND Android up and running over MAGLDR.
I've noticed that Ubuntu can now be booted over MAGLDR and I have decided to give it a shoot, since it's easy enough to try.
I have done everything that has to be done, but the problem is when trying to boot over MAGLDR I get this message:
"k: zimage sd kernel open failed"
I do have the zImage and the initrd.gz in the root, also the linux folder.
I've tried going to Services > Boot options > AD SD to choose from where to boot, but it jumps back to main menu.
That's the problem and I'm guessing that MAGLDR doesn't recognize my SD card.
Btw, it's a Kingston 8gb formatted to FAT32 Primary.
I hope you guys can help a fellow HD2 owner out!
Is your recognising SD Card otherwise, other than MAGLDR?
I have faced a similar problem where neither WM6.5 or WP7 or MAGLDR or CLK detect the SD Card however it is detected by bootloader.. See link below

Hello,
it recognizes the SD card everywhere except in MAGLDR.
In the mean time I found a exact same thread like my problem:
http://forum.xda-developers.com/showthread.php?t=1315808
Basically it tells me that my SD card just doesn't work with MAGLDR.
So, has anyone found a solution that doesn't involve buying a new SD card?

Unfortunately that thread is right, your SD isn't compatible with MAGLDR. I have the same problem with my Kingston 16GB class 4, so it appears to be something to do with Kingston cards. You should have received a Sandisk with your phone, which is enough if you want to use SD builds only to try ROMs out, but there isn't much you can do to sort it out I'm afraid.

Alright,
well that's kinda sad, tho I still thank you both for the info.
I'm having a similar issue with my 32gb Sandisk class 4 card. It used to work fine, but then Magldr stopped seeing the file structure for sd boot. With trial and error I used gparted to recreate a ms-dos partition table. Just now magldr sees the file structure again.

Found a solution, thanks for trying to help guys! :victory:

Was it this? If not, then would you be able to explain how you did it, please? I have the same issue so it would help. To be fair, I haven't really tried to resolve it properly yet, so it's probably an obvious solution which I missed.
It doesn't work once again...
Tho what I did to make it work is using "MiniTool Partition Wizard Home Edition":
1.Delete the partition
2.Create Partition: set Primary, set Fat32, set allocation table to 32K
3.Apply
That's basically it, I copied all my files excluding the linux ubuntu I wanted to try over MAGLDR...
Next day I tried to select AD SD dir and it OPENED it up, I was amazed!
I then booted android, selected to copy over usb, copied over Linux(around 3.2GB).
I rebooted back in to MAGLDR, tried to select AD SD dir and the same problem occurred... :silly:
I have no clue what else can be the problem, I tried then deleting the Linux, because it worked without it, and again same problem...
So basically it stopped working after I connected the sd card over usb while on android to copy linux... from that moment I couldn't select AD SD dir any more, just jumps back to main menu.
I would like suggestions if anyone knows what might happen?
Was I lucky to just make AD SD dir working? Or was it the allocation table I mentioned that I changed to 32K?
EDIT:
I've been thinking...
Since my goal is to have an android NAND and a Ubuntu over SD, is that all possible if I switch the bootloader from MAGLDR to CLK?
I've never tried CLK, but I'm sure it boots Android NAND's just fine, but what about Ubuntu over SD? Does it have problems recognizing SD on CLK?
