[Q] Boot Different OS from SD Card without Root? - Nook Color General

Okay in a different thread there was a comment that the Nook Color could be boot off of an SD card into a different operating system without root.
Someone referred my to "any froyo discussion" about this when asked. Everything I have come across requires running some ADB commands, which I thought required Root. SO I am thoroughly confused.
With most items I would have no issue rooting it, then following the discussion would be simpler. In this case, I want to be able to boot it stock, and retain things like access to in-store features, or boot it into a different version (could care less which at the moment), and load apps, etc. on it.
So please forgive the noob aspect of this, I just want to be sure I am understanding the process before I try to duplicate it.

you don't need root as its booting from the sd card before it even loads the 2.1 os thats on the device (emmc)
i.e. this thread http://forum.xda-developers.com/showthread.php?t=883175 is the initial nookie froyo, you burn the image to sd and then stick it in the nook color, when you boot it just boots from sd and ignores the emmc, being rooted helps it none because it never loads the os that the root would be on

Follow-up
So my next question would be: Do all of the various OS flavors that are out there working on Nook Color work as an SD bootable image, or only the Froyo that was referred to above?
I am guessing (will search later) that there are repositories where I can get things like, say, the market, since the version of Froyo above seems not to include it.

[Q] SD Bootable Unrooted Nook Image?

I am sorry if this falls in the "dumb question" category, but I am wondering if anyone has created an image of the Unrooted NookColor system that could be booted up from the SD. This would allow me to attempt a boot from SD when I want the Nook to look/act like it did before rooting without the hassle of unrooting and re-rooting.
I wouldn't say dumb, but the answer is "no" though I would love it myself, as well as a bunch of others too.
This would be very handy. To run the Nook fully rooted and eventually all nookied up running all internally it would be ace to slip in an SD card and get all the deals from B&N and occasionally read a book

I attempted to do this some time ago, changing all instances of mmcblk0 to mmcblk1 in init.rc in the ram disk. The SD card image was unregistered (you had to go through the first start steps of putting in your B&N account) and the image on the internal flash had been started and registered.
If I remember correctly, I was able to boot and register from the SD card. However, when I removed the SD card and booted the internal flash, it acted as though I was unregistered, and there were other troubles as well. I restored it, and didn't pursue it further.
This indicates that there are other places where you need to switch from internal flash to SD card so that your internal flash doesn't get written to.
I made the backup using auto-nooter-2-12-15.img.zip where I modified the ramdisk not to actually run the auto nooter script. (you just remove it from /etc/init.d/) I could then log in via SSH and dd the internal flash to the SD card.
The idea about changing mmcblk0 to mmcblk1 was in this thread: http://forum.xda-developers.com/showthread.php?t=873243

Bump to the top. . . just because I am curious if anyone is still working on this. Any takers? With the ability to flash Froyo to the EMMC, it would be really nice to have a non-rooted version of the original NC that we could boot from SD when doing the B&N Reader thang. . . .

[Q] Possible Nook Color Partial Brick

I have screwed up my nook. Need some input. I was running nookie froyo on the internal mmc when I wanted to try out the honeycomb rom, but it seemed to hang half way through, so I rebooted the device. But it wouldntnt turn on. Now the nook color will not boot up unless I have an image on the micro sd. I think I may have corrrupted my internal flash. How do I fix it?
I have tried booting up clockwork and repartitioning data and system and reinstalling stock but still wont start without the micro sd.
Any suggestions?
You need to reimage your boot partition. There are several threads on this in the general forum. Including one asked by me where someone linked to several threads and I replied with the exact thread I used to get the boot.img.

[Q] Need Help With Dual Booting

I would have posted this question on the developer board, but I am too much of a noob. I am wary that my question will sound like jibberish, but I am really confused about dual booting and the special files that are necessary.
I am using rooted 1.1 stock and have got it customized about as far as I can go. I want to run CM7, but the one app that keeps me tied to the Eclaire OS is the original B&N reader app that allows downloading of magazines and newspapers. From what I gather, the standard Market Nook app does not allow magazines and newspapers to be downloaded. I saw that some on this board are trying to port the original stock reader to Froyo and CM7, but they are not there yet.
Because I want to keep 1.1 and still try out CM7, I am looking to either boot CM7 off an SD card or dual boot 1.1 and CM7 in eMMC. I have yet to see a solution for booting CM7 off SD, so I have turned my attention to dual booting.
There are threads and files on the development board that allow for dual booting, but I can't quite figure them out. If possible, I would like to have the current 1.1 placed in the "alternative" partition (Power+n) and CM7 in the main partition (Power). Here are my questions:
Can I dual boot my existing 1.1 and the latest version of CM7 (14)?
Can I do this without any specially modded ROMs?
Does running the partitioning program destroy the existing 1.1 setup?
There is also a "script" to move the current setup to the new partition. Does that mean that my exising 1.1 setup will be left intact after the partitioning and can be moved without any alteration?
If so, do I need a special version of CM7 or will it automatially flash to the proper partition?
Assuming this is all possible, how do I use adb with all of the partitions?
And lastly, is CWM still usable in this type of arrangement?
I am sorry for all of these questions and I hope they kind of make sense. Thanks very much in advance for any help.
All good questions. I can only answer number 3. the partitioning zip will not destroy the BN install. Just makes the free space on the emmc smaller. Well it does more then that, but that is what you'll notice when using the BN install. I successfully used it to dual boot with HC. There is a bug with CWM 3005 that you'll run into if you follow the HC dual boot instructions from addictivetips. Use CWM 3010 or look for the shell script you have to ADB onto the CWM to allow CWM 3005 work with the dual boot script.
I'd love the answers to the other questions as well.
This is the fastest and easiest way I found to Dual Boot. Works flawlessly.

[Q] Putting rooted CM7 OS and Apps on bootable SD card?

Ok, first off let me say that I am a new member and love the site. There is a ton of great information on the site, but I seem to be having trouble finding an answer to my specific situation.
After hearing about honeycomb and gingerbread being installed on the NC, I decided to give it a shot. After reviewing each OS, I decided on going with gingerbread. I followed a youtube video and a few threads on XDA and eventually installed the gingerbread OS, Gapps, and Netflix.apk files on my Nook. Everything worked fairly well and I was happy.
My question to you all is, would there be a way to take all the apps, OS, etc. that I currently have on my Rooted NC and make an image of it to then put on a bootable SD card?
My ideal end result would be to have:
1. a Bootable SD card with my current apps, OS, etc. on it.
2. a freshly restored nook color.
3. the ability to either remove the SD card to switch between the GB/NC OS, or have a boot option when booting up the Nook.
Any help with this process would be greatly appreciated!
Thanks in advance,
Nick (Nudarkshadowl)

I'm apparently and idiot. Help?

I bought my daughters Nook Colors for Christmas. They are registered on B&N and are running the 1.4.1 B&N Software. I've been trying since last night to figure out how the heck to get these things rooted and get CM7 on them.
I followed these directions (androidforums.com/nookcolor-all-things-root/327798-how-make-bootable-cwm-clockworkmod-version-3-2-0-1-recovery-sd-card.html[/url]) and cannot get it to boot to clockworkmod. No matter what I try, it just boots up to the nook software. I'm using a 2gb Sandisk card.
I'm not new to modding, I've been running CM since the G1, and I thought I knew what I was doing. Apparently I don't. I've been reading threads all over here and everywhere, and until I can get past the rooting step, I can't do anything.
What am I doing wrong? Can I wish for a Christmas miracle and maybe someone can walk me through step by step what I should do? I'm frustrated as can be.
You do not need to root the stock firmware if you are planning to run Cyanogenmod from either SD (external) or eMMC (internal).
It may help to keep in mind that you have no less than three options, each of which require different steps.
If you want to root B&N 1.4.1, read up a few pages in GMPOWER's updated ManualNooter thread in the Development forum: forum.xda-developers.com/showthread.php?t=1400486 HINT: Load ONLY his latest ManualNooter on BN 1.4.1. Be sure to block automatic B&N OTA updates to preserve root in the future.
If you want a bootable CM install from SD, try the Size-Agnostic bootable thread: forum.xda-developers.com/showthread.php?t=1000957
For an internal eMMC install, his thread looks good: forum.xda-developers.com/showthread.php?t=1030227
Sorry, I'm at the ER and can't search right now. Editing forum posts on my NC is a bit awkward!

I do want to do the internal eMMC install, but that also requires the CWM bootable sd card. That's the step I can't seem to complete successfully.
Got it up and running!! I think I must have had a corrupted CWM bootable file or something.
