[Q] better way than booting from sd?

ok guys, noob here ive got my nook running cm7 off the sd card itself but its super laggy, and i cant stand it is there a better way to root it so i dont have to use the sd card and which method has the best success?
If you are not using a sandisk sdcard, you should give a try:

Good luck!
any others???
this pny class 4 8 gig card is the only one i have im down to re root the whole thing if that is what it takes... i just wanna have something that works half way decent
I've had bad luck with the PNY cards.. Sandisk made it run really well.. amazing difference..
ok cool ill find one somewhere
Best way to use CM7 is off your internal memory.

Absolutely, no brainer.

But the question now is, do you want to upset your stock OS or not?
Or is there a new way to install CM7 on your eMMC without interupting the stock OS?
My NC is still under warranty so I don't want to take the stock OS off yet, although I am very tempted to trade places, putting my stock OS on the SD card and CM7 (as I use it so much more) on the eMMC.
If you don't want to touch the stock OS yet, the sandisk is optimal for these units.
In fact, if you will dig around in posts about SD cards and CM on AD cards, you will find opinions and actual performance tests showing that CM from an SD card can be as fast as CM from eMMC... if you use the correct card.. which is a Sandisk class 2 or 4 of any size.. 2gb and up.
Don't ask me to point you to the posts.. I can't. I only remember reading these things when I was doing similar research.
For $10-20 you can give it a try and do something else if you are not happy.
.. or if you are sure you don't need easy access to stock, go for an eMMC install..
Neither solution is irreversible..
There's nothing the stock Nook can do that Android can't and there's probably a list somewhere of the things Android can do that the stock NC ROM can't but it probably wouldn't fit in this post. Search for 8+1, you can always fall back to "so clean the video wants to play".

Thats not an issue as you can always restore to stock if there is a problem. That is Part of the greatness of SD boot priority. You can restore no matter how screwed up your internal memory is.

The warranty is not really an issue as I found when I had to have mine replaced. You just restore it so stock. When you create your install image SD card save it in case you have to return your Nook. If that happens, just place the stock ROM .zip on the card and boot from it and wipe everything like you were installing CM7 all over again but instead just flash the stock ROM. It can be found here: http://www.multiupload.com/BW8FIEJ2GH (With thanks to Taosaur.)
ok so now ive got the sandisk card in it it benchmarked 1888 i was way supprised but now it doesnt show up on my computer when i connect the nook via usb i want to still put books on it but it wont boot if i put the books directly on the sd card itself

I didn't follow all posts from the beginning so I just make assumption that you're booting CM7 off the Sandisk uSD.
No personal stuff should be placed in the boot partition. Place them in the left-over (/media) storage.
Just install it on the internal memory there are many great Tutorials on it.

I can tell you that I have been running CM7 with nightlies off the uSD card since I got it (3/11). Using an 8gb Sandisk is indistinguishable in speed from the stock system, but SUBSTANTIALLY more useful. Since my NC is still under warranty, all I have to do to "restore" it to stock is take out the uSD card. I love it, and it doesn't take you into the "restore to stock" mess that, while it works fine, is still pretty stressful.
Try a good Sandisk uSD; you probably won't need or want to flash your internal memory.

SD card

Hi all,
So I'm doing this bootable Honeycomb SD card thing for the Nook, but I have a 16GB card that after writing the image onto it, the nook only see about 1GB left of storage. I don't know what I did wrong and how to fix it. I tried to partition the card into 2 different partitions, but then my computer would only recognize the first partition and not the second...
Does anyone have any idea? Much appreciated.
I'm sorry, posted this in the wrong forum. Would someone be so kind to move it to Nook Color Q&A please? So sorry, and thank you!

agreed, sounds like a nook color question since you can't boot off sd on nook touch.
but to the original question. You will want to find a utility that can resize the partition without destroying the data on the partition.
Agreed, moved to nook color Q & A.

Get Easeus Partition Master (it's free) and resize the last FAT partition (not the boot partition!) to fill out the remaining unallocated space on the card. It should be completely non-destructive and will give the rest of the storage card capacity.

[Q] Is there any way to dual boot

I am just wondering if there is any way to dual boot the nook simple touch from an sd card? I know of dual boot sd cards for the nook color and nook tablet but I havent heard of one for the simple touch, so I thought I would ask the community if they know of one.
Currently, no. You can run CWR from a card, but that's about as far as that's gotten (to my knowledge). There might be some kind of early custom ROM soon though, with all the leaps and bounds this community has been taking lately.
Good to know, thanks for sharing
What else would you boot, other than android?
The idea is to boot into Android off the sd card and then boot into normal nook form the hardware just like the cards do for the nook color and nook tablet

No, he means actually boot a self-contained android from the SD card, like this for the NC.

So i have been talking with some developers and they say its possible but that no one has built a boot menu for it yet. I am willing to help build one and test it out on my device if any one that knows what they are doing wants to help out that would be awesome

Dual boot job and Ubuntu from SD?

Is there a way to run Ubuntu from the SD card and still run one of the JB ROMs?
Any help would be appreciated

I believe the only way is through the pseudo dual boot over your SD card, found here.

CM10 Internal EMMC

Is it possible to install CM10 on the internal EMMX of Nook HD. I know that it is possible to bypass the Nook HD bootloader to prevent it from checking if all the files match. I want to know how to do that with bootloader.
Thanks

It is possible. Hack away. Just don't bug the rest of us always asking for how to do it when most of us don't have a clue. Very few do. It takes some very talented people to figure it out. Do you understand how to read, modify and write code? That is what it is going to take.

I do understand how to code. But I don't understand how these systems are set up.
Can anybody explain exactly what "locking" the bootloader means? Is the boot code in the Nook's OMAP ROM designed to check for a cryptographic signature in images it loads from EMMC storage? Even though it doesn't make any such check for images loaded from the SD card? (The OMAP Wiki doesn't seem to mention anything about checking signatures.)
I tried overwriting the first 8 MB of /dev/block/mmcblk0 on my HD with the partition table and VFAT boot partition from a CWM Recovery SD card. It would not boot, even though the the HD boots perfectly well off the card.

sox again lol but for CM10 how to install GApps. I did the boot from the "cm10-sdcard-imager.img". Do I now install CWM on it with "sdcard-cwm-hummingbirdv4.zip" file and install the GApps.
Thank You

You are right about the bootloader checking crypto codes on emmc. And it does on SD too. Verygreen has just found a loophole to defeat the check. That is your challenge, find a loophole to defeat the lock on emmc. Study verygreen's code and you may get a clue.

I assume you mean use emmc (internal memory media storage) as "sdcard". Usually with CM10 you can add a simple file to swap emmc and the real sdcard. But because of the way emmc is mounted on this device, that does not work. Why do you want it? There is a work around if you really need it.

Yes, emmc is the thing i mentioned. I dont see it on my nooo then cant use it as storage.

If you just want to use it as media storage, it is available as "emmc" in your file manager. You can copy files there. And you can sometimes set your applications to use "emmc" instead of "sdcard". Is that what you want to know?

What file manager are you using? The one that comes with CM10? If so go to settings in the lower right and click on it. Then general, then access mode and select root. Then you can go to sdcard0, which is internal storage. That file manager is very bad. I recommend you get root browser lite in play store.
