I've seen this asked once before without an answer. I know it's an odd question. But is it possible to dual boot from a single SD card?
In other words, two totally different installations on a single SD card + the Nook kept at stock.
I know I can root the Nook directly. But if at all possible I'd prefer to keep it at stock. Nookie Froyo has been running great from my SD, so I'd like to just stick with it and not touch the Nook itself.
At the very worst I can pick up a new SD and swap them out if it's not possible.

I just got my "new" nook and tried to boot Froyo 0.6.8 from an SD card. It just gets stuck at the blue ANDROID_ screen. I tried Froyo 0.6.7 and redoing 0.6.8 but it never got past ANDROID_. I'm using a new Transcend 4GB class 6 card. I first tried writing it using WinImage and my laptop's built in card reader, but when that card didn't boot I tried using a USB card reader and Win32diskimager. The Nook came with 1.1 on it and I haven't done anything to the internal rom.
Any ideas? How long should it stay on the Android_ screen if its working?
Did you figure this out?
This sounds like the classic failure described with 16GB cards on multiple threads. There's a nice consolidated thread on cards that are known to work. I'd check that. I have froyo working beuatifully on an 8Gb class6 transcend card.
Most likely you have some glitch on the card. I would do a complete deep wipe of the card (e.g. using SDformatter, all options). Then reflash with win32diskimager, then expand the SDcard partition with EASUS
it should boot in a couple of minutes tops the first time round.
I looked at those threads about cards before I bought one and the Transcend 4gb, class 6 I got is one that seemed to work.
I haven't been able to get the nook to boot off any card. I tried doing the format suggested and tried another 1gb PNY card with the bootable clockwork. I've tried writing with the internal SD writer in my laptop and with a Kodak (sakar) usb writer and with Win32DiskImager and WinImage.
I suppose the USB writer I have might not be good, but I don't want to get another one without knowing its one that works. So far I don't know whether the problem is with the cards I'm writing or for some reason this nook won't boot off SD card.
Thanks for the suggestions.
I probably had a flaky 4gb card. Now it won't format or write whatever I do.
dumb Q, but is the 1gb card you ahve also flaky now too... in which case it might well be the reader?
Will your nook stock OS read the SD card? (e.g. throw some photos ont here and see if the nook will show them) that way eliminate the nook.
There's some older threads that suggest first formatting the SD card with the nook stock OS, but I've never needed to do that.
I'd persevere - there's definately some plusses of froyo over the rooted B&N (especially if you use adhoc networks a lot), and you absolutely need nookie froyo as a backup incase you fry something when you take the plunge to CM7 (which is phenomenal, despite being so early in its release)
The 1gb I borrowed seems ok. I managed to boot a card with a bootable clockwork on it. I didn't do anything to Nook stock OS yet. I want to be clear that I can recover if I do first. I did get another reader, but I think it was probably the card. I wasn't able to boot of the 1gb at first because I was making a mistake in unzipping the .tar.gz files.
Do you have any pointers of where to find out about how to use Clockwork recovery?
I am using 0.6.7 on a 8gb class 6 Transcend... it's working great, no issues with booting.
I've dealt with many ROM's on my OG Droid so I'm confident in my ability to root the nookcolor. However, one this eludes me so far. The SD card.
Do I need to buy a small SD card that has the ROM I want on it which the nook will always boot from? Or is it a one time deal where the nook will load from the SD card and keep it in internal storage. I've done some searching but I haven't been successful, obviously. So I apologize for starting "that" thread if the answer already exists.
alright so i rooted out my nook color and now i would like to get NOOKIE FROYO 2.2 on my device. I have read everything but there is one question that i have that no one seems to put out there. And yes i am new to rooting etc. but rooting was damn easy and looks like loading nookie froyo to sd card is just as easy.
Question (probably dumb) is running the bootable sd card on my already rooted nooko color alright?
2) and it is really as simple as writing the nookie froyo image to the sd card plugging it into the nook and rebooting that simple?

1, as far as I know running roms off sd card is very safe, rooted or not rooted.
2, Yes... burn nookie froyo on sd card then turn on NC.
Yes, running from the SD card is safe.
I second what Pinoy8125 wrote.
1. Running off the SD card is safe and easy even with your interal memory being rooted. Look at it this way, you can try different images just by swapping different sd cards. Try the 6.8, 6.7, HC, etc.
2. Yep, just burn the image onto the SD card. Expand the 4th partition if the image size and the card size differ. This will allow you to recover the lost space. Turn on the Nook and see what you go.
I am getting very nice performance running Froyo 6.8 off of the SD card. I ran into micro sdhc compatibility issues which caused booting as well as performance issues. I have another thread out there on this issues. Awaiting people's feedback on this.

"2. Yep, just burn the image onto the SD card. Expand the 4th partition if the image size and the card size differ. This will allow you to recover the lost space. Turn on the Nook and see what you go."
Now... I need help...how to go about expanding the 4th partition to recover lost space? I don't have a single idea on how to do this. Please explain it in details
I followed the like here to put a copy of stock 1.2 on my sdcard http://forum.xda-developers.com/showthread.php?t=1061523
I am about to replace CM7 back on my eMMC, but I was slightly confused about how to make nandroids of CM7. Given the fact that CM7 requires an sdcard for storage, do I have to have a separate sdcard in order to make nandroid backups or can I simply use the sdcard with stock 1.2 now on it? Thank you for the clarification.

How many cards do you have. If you have only one you will either have to buy a new one or wipe the one you have just to do the install. I kept my original card with the install image on it in the event I ever totally screw the Nook up and have to start from scratch and just bought another card for use with CM7 on the eMMC. You can always wipe the card clean again after your install and use it, but you are probably better off buying an additional card "just in case". You can't leave the card as is because if it is in the Nook when you start up the Nook will automatically boot from the card. You don't want to keep switching it in and out every time you use the Nook as eventually the card door will probably fall off and ultimately the contacts will stop working. Cards are cheap.

As of now, I have 2 cards: one with stock 1.2 on it, and another used as storage for CM7 for nandroid backups and whatever else. If possible, I would like to just have the one to serve both of those purposes, but I wasn't sure if that was possible.
As far as keeping the stock 1.2 card in the slot...someone in the aforementioned thread made a comment about replacing the u-boot.bin file with the one from this thread for a boot menu. I gave it a try and it worked. I was able to leave the stock 1.2 card in the slot, power on, and select to either boot to CM7 on emmc or boot to stock 1.2 on the sdcard. But I switched it back to the original u-boot.bin file, since I needed a storage card for CM7, which is what I run 90% of the time.
Is there any hope for using the stock 1.2 card as the CM7 storage card, as well?
You can't use a bootable card for storage unless you want to keep taking it out when you boot up first. The NOOK will always boot from a bootable card if it is in the slot unless you use a dual boot system. Even then it is booting from the card first and then switching to the eMMC.
I recently updated my Nook with dual boot from the SD card but I find that it locks up a lot and it very slow. I figure it is probably the brand of SD card I am using but now I am wondering if I really want the original Nook software in it at all. Is it possible to dual boot without using a SD with two exact CM7 Roms, one with all my info and one with my wifes?

Yes, it's possible, but I don't recommend it. There are old threads that will tell you how to do it. I recommend against because to implement you must repartition emmc and that is risky. And you will have problems in the future if you want to update the ROM on the second system.
I recommend putting one system on emmc and another on a quality SD using the verygreen system. That's what I run and it works great.

OK thanks for the info. For now I have CM7 on the Nook and it runs 100 times better than when I had it on the SD card.

With a good SD card it should run just as well as it does on internal. San Disk class 4 tend to work the best as bootable SD cards.
I tried to post a link to the card that I want to buy but I dont have enough posts

Just get a San Disk and that will take care of any potential card issues. This is the best possible way to avoid any potential issues with running a bootable SD
