Dual boot without SC card?

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

[Q] A few questions on what is going on

So I purchased a nook hd+ on ebay, and I've been reading around am just look for some straight answers before I take a dive.
I want a little understanding of what it is going on.
Is what is being run aosp android, like cm10 or are people just running gapps in the stock b&n os?
Can whatever things are being run have no other choice but to run on an sd card, or can they run from the internal memory?

You currently have two choices, run CM10 or CM10.1 on SD or run stock on internal either virgin or modified for root or gapps or other mods. We cannot run another ROM on internal memory yet.

So I can't root or use CM10(.1) unit I get an SD card is what I'm understanding right?
And has anyone confirmed you can use a 64gb sandisk uhs-1 card for this?

You are understanding it right. SD is necessary to root and SD is necessary if you want CM10. Some have said those SDs are ok. To root it can be any card, even a 1GB card.

I waited for an SD card to come over the weekend and I was finally able to add GApps to stock.
I've been liking the experience so far, but I was wondering how multitasking works on stock.
The stock launcher doesn't seem recognize apps from the play store.
Is there a different way to switch and/or close apps?

The zeam launcher came with gapps (rev1) so that can be used to; launch the apps added with play store. And there are other apps that let you see recent apps. Like recents plus.

[Q] Increasing SD transfer speed

I have the stock NookHD rooted but was wondering how best to implement a higher cache speed on my SD card (class 10 PNY) If I can use an app I'm hoping it does not mess with the /system, But maybe there is a better way? (A flashable zip in recovery)
The reason I ask is because when transferring media files between the pc and and BNTV400, it either lags/crashes or in other cases moving files already on the card says it will take upwards of 40 minutes to complete! Is this really how they want the Nook to function?
If I'm looking at this the wrong way please let me know!

Part of the problem is that pny SD. They are horrible with these devices. And the stock kernel does a bad job with with external SDs. Not much you can do except get a different card.

FYI, I'm using Trancend class 10 SD (32GB) on Nook HD+ and it seems to work with no issues. http://forum.xda-developers.com/showthread.php?t=1005633 thread has even list of good and bad flash cards (in terms of IO, especially random 4kb IO. You may check this thread choose a replacement.

How likely do you think it would be in the future that we get a custom kernel? Obviously I don't think any of us would be running the stock OS by then either but would it have an impact on the speeds both internal or external? I'm hoping it's not a limitation of the hardware.

I will look into it for future expansion, I just hope that it's the card and not hardware differences between nookHD and the HD+

If you are running CM10 on HD+ you are running a custom kernel. Verygreen builds his own from B&N source. And he customizes it. He says the SD problems seems to be hardware related.
But, because of locked bootloader issues, it may a long time before custom kernels come to stock.

[Q] Having Trouble Creating SD Card with CM7 for Nook

I need some help with creating an SD card to boot android from on a Nook HD.
I tried this guide:
http://forum.xda-developers.com/showthread.php?t=1000957
I used an old 8gb sandisk micro SD i got from a cell phone
Used win32 disk imager and flashed generic-sd card image onto the root of sd card
Then I took out the card and re-inserted it to get it recognize the new image as F:boot which has 4 files on it MLO U-boot, U ram disk, and u image
Then I went to install CM 7.2 files onto the SD - that's where i ran into trouble. It gave "Error No Room on Disk". I looked at the space on the Sd card and it said it was only 113Mb. _Please help. What did i do wrong when flashing the image file onto SD card to make the sd card smaller?
Thanks in advance for your help.

You have really got things mixed up. This is a Nook HD/HD+ thread and you linked to a Nook Color thread (they are different devices). CM7 does not run on the Nook HD. No wonder things are not working for you.
If you truly have a Nook HD, find a Nook HD thread for installing CM to SD (has to be CM10/CM10.1/CM10.2 though).

Thank you for the reply. I checked and yes I do have a Nook HD 8GB. I got it from walmart for $129.
So just to confirm - No CM7 will run on Nook HD?
Can you install CM 10 without rooting the device? And if so, is a non-rooted install that runs directly off the SD Card significantly slower than it was flashed to internal memory?
If CM 10 has to be installed to the internal memory, are there dual boot options that would keep what i have on the nook saved?
Also, I noticed when i tried to put CM7 on the SD card, it created a 113 image file, and left the remainder of the disk as "unallocated" - so during the install process how does that unallocated space get turned into usable space?
Any link for the build I need would be very appreciated. Not trying to get anyone to do the work for me, with all the different builds and install files, its complicated for a first timer.
Thanks for help

No, CM7 will run on the Nook HD.
You do not have to root stock to run CM from SD. You can run CM10.1 from the SD and leave stock intact. So you can boot back and forth. If you do, I recommend the hybrid install here:
http://forum.xda-developers.com/showthread.php?p=36668001
It runs more quickly and has more stability. But be warned the instructions can be confusing.
There are no dual boot options that allow you to fully install two systems to internal memory.
And that old Nook Color SD that you used is different than how the Nook HD SD is installed. But you do have to follow directions to get everything to work and fit.

Nook fails boot into recovery ...

My Nook HD plus will no longer boot into recovery.
An error message that an install failed and to contact Barnes & Nobel tech support.
I have CyanogenMod version 10.1.3-ovation and would like to upgrade to 10.2 ovation (Jelly Bean).
I tried TWRP Manager but itdoes not work either.
My Nook will boot up normally and I can use the Cyanogen version rather than the stock Nook OS.
How can I fix my Nook?
Thanks

The problem is you did not install CWM to your internal memory. That installed failed message is from stock recovery which is still installed. Go to the dummies guide and install CWM to internal memory.
This comment assumes you installed CM to internal memory replacing stock. If you installed to an SD and stock was left intact, then the answer does not apply.

Been so long since I did this, I forgot the details.
In addition, my Micro SD card is corrupted with me messing with it.
Can I install CM to internal memory without an SD card?

I borked my 32gb micro SD card.
I can format it but when I write data
On it, the contents is scrambled.
Seems like it needs a low level format.
Any fixes or do I need a new SD card?

How are you formatting? You should be using SDFormatter free on the web.

I originally used Win32DiskImager on my 32GB MicroSD card and it transformed into a 4GB card.
But, it did allow me to root my Nook and install JB.
Later I learned about SDFormatter and through some manipulation got it back to 32GB and allowed
me to downgrade from JB to ICS. At the time JB was nightly and I had some problems with it.
But, now the microSD card is acting flaky and I've delt with "lost semaphores", "read only", and "unsupported device"
messages.
If there is no program to restore the SD card to its original state, perhaps I just need to go out and purchase another one.

If this doesn't work the card is dead. When you put the image on with Win32DiskImager it was supposed to make the card look like a 4gb that is normal.

For the record, I figured out how to fix my 32GB MicroSD card.
I had trouble with it not working with thiese type issues:
- read only
- SDFormatter failed several times
- when I did get SDFormatter to work and then put the boot files on the SD Card, the filenames were scrambled.
- "lost semaphone" error
- "unsupported card type"
- etc.
What I think I did that fixed my SD card:
- used a different adaptor for the Micro SD card - I started with an SD adaptor, then got it working with a USB adaptor
- CHKDSK /F on Windows PC reboot
- Run SDFormatter → Option → FORMAT TYPE → FULL (Erase) (took 3 hours until completed)
- Ran MiniTool Partition to set the partition Active to make it bootable
- Now I have a 32GB MicroSD card that will boot my Nook HD plus
The reason I wanted to upgrade from CM 10.1 (ICS Icream Sandwich) to CM 10.2 (Jelly Bean) was that
when I started using my HDTV adaptor to display Netflix on my TV using the HDMI cable, the screen
would pause quite a bit on the TV during the video, but continue to play on the Nook.
Upgrading to CM 10.2 Jelly Bean fix this screen pause issue.

Just a point of clarification, CM10.1 and CM10.2 are both Jelly Bean, just different versions. Stock is ICS.

Hey thanks. I'm still a nube with all the version of CM and Cyanogen.
I've done some Java programming using the SDK on my Android phone
but never spent enough time learning all the intricacies - too many other distractions.
Thanks for your help and clarifying things for me.

EMMC means Embedded Multi-Media Card. It is the internal chip that comes built into the device where all of the operating and data files are stored. It is identical to an SD but is embedded into the device. The term gets loosely thrown around as applied to anything that is internal storage.
