    Boot from SD Card on my 8GB Nook Tablet

      I gave my Nook Color to my son yesterday and went and purchased the 8GB Nook Tablet. I really like it, very fast, sites load almost immediately, very snappy from one task to another. I had not heard and was wondering if there was a way to boot from an SD card to CM7, so I tried Google. To my surpise there was and in about 15 minutes I had an SD card made, put it in the NT, and am happily running CM7 on my 8GB tablet right now. So far so good, seems very stable and no problems. CM7 on the NC was good, on the NT it is awesome and lightning fast! I've got all my Market apps installed and running perfectly. The only problem was that the Google Play app wss not included with the CM7 I wrote to the card, so i had to download it and install it seperately. But it was just as easy as downloading and installing any other app. If your looking at the 8GB tablet you now have the option of access to the Android Market.

          That is great!! Enjoy your new NT.


          can you let us know the link or web page where you found the instructions?

           

          Thanks

            I seem to be having the same problems that Kenborg is having.  I posted this in the comments section of the instructions page:

             

             I was able to boot from the SD card, but ONLY when my Nook Tablet was plugged in to the power cord. Once I removed it and went to battery, it would boot into the usual NT environment.  Also, the 'Reboot Into Recovery' for gApps installation didn't work, either.  The Nook would halt the startup and ask me to try rebooting.  


            Any suggestions?  I'm running a Nook Tablet 16GB, OS 1.4.2, with a 32GB Class 10 SD Card.
            Thanks!
            I've also tried the suggestions on this board, and have gotten the 'factory reset' message, but no booting into CM7.

                Yes, mine too boots into Android when plugged in to power cord.  Without it, it boots into NT.

                    I did this yesterday but on a new Sandisk c4 8GB MicroSD (the previous card is 1 16GB from another manufacturere).  It worked this time.  So I'm convinced that this card changed the outcome.

                        I think it is the class 10 card - I tried with a class 10 and the same happened to me - I also tried to use the class 10 as a simple sd card - no good either does not show in settings although I got a card removal message when I removed it - tried a class 4 as an extra card and it worked fine - I have not tried the dual boot on the class 4 sd card yet - I can't seem to get the disk image when I unzip the CM7 file from the xda site - the file I originally used is on my currently unbootable desk top - computers are such fun -

                            I highly recommend getting a card/file from android for nook.com.  Just make sure that you use the SanDisk care as recommended or puchase one from him already loaded.  His prices on 32gb card was cheaper than what I coulc get for one locally.  You do have to have some knowledge on the Android OS, but mine works like a dream and haven't seen a reason to go back to Nook, yet.

                          After spending days trying every way in creation to boot from the SD card, this method of booting while plugged in via the power cord worked immediately. Does anyone know what the fix is to this? My NT only boots from the SD Card when plugged in using the power cord.

                          Just wanted to give an update:

                          I just went out and picked up an SanDisk 8GB Class 4 Micro SD card and performed the steps outlined above.  Everything worked just fine and I was able to boot into CM7 without a problem.  This tells me that the problem lies either with the brand SanDisk vs Lexar (the 32 GB card), or the Class (4 vs 10). 

                          The only other issue I've seen is that rebooting the Nook causes it to go into the Nook environment, while a cold boot will launch CM7.  Not an issue, except that I can't perform Step 5 as listed above because I cannot 'Reboot Into Recovery'. 

                          Please pass this along, and if there's any suggestions for installing gApps, let me know.

                              Is the card you are creating a boot card that you run CM7 on and then you can take it out, restart and be running regular NT again?    I have a card like that for Nook Color, and I want to make one for NT.    I don't want to modify anything on the NT, I just want to run on the SD card and go back to stock if I want.

                                  when I cold boot the NT, it goes into CM7.  a reboot brings up the regular Nook environment.   To get back to CM7 I have to shut down and start the Nook from scratch.  No big deal.

                                      A thought strikes me, could one of you who have successfully created a SD that works flawlessly post the web addess for the download of the xda file? or did you use the link from the liliputing?

                                          The link I posted earlier will take you to liliputing, the link in that article will take you to the xda site where ou can get everything you need to write the card.

                                              I created an micro SD bootable card according to the instructions on liliputing.com.   In step 3 it mentions that Win32DiskImage may only write a 4gb partition.    I have a 8gb card and I reformatted it so it would show 8gb available.   After I write the Team-B-CM7SD-Alpha_final.img image, the SD card shows that it is a 200mb card.   Is there a way to make it be 8gb again and still have the image on there?

                                                  It shows a 200 MB card because the Windisk32 imaging program creates 4 partitions on the card and the first partition is only 200MB:

                                                   

                                                  The first partition is the boot partition which just has a few startup files.  This is the only partition that you can see in Nook mode or when the card is in your cardreader, plugged into the PC.

                                                   

                                                  The second and third partitions are hidden and contain the Android operating system.  Don't even mess with them :smileyhappy:

                                                   

                                                  The fourth partition is your available space to use for downloading and storing files.  Since you have an 8GB card and the image you downloaded is created for a 4GB card, you have some unused storage you need to claim:

                                                   

                                                  1.  Download a free program called Minit Tool Partition Wizard from download.com and install it.

                                                  2.  Insert your micro SD into a cardreader and plug it into your PC.

                                                  2.  When you start the partition program, you will see a couple drives.  One will be your hard drive (maybe you have more than one) and one will be your micro SD card.

                                                  3.  You will notice the micro SD card has 4 partitions, as mentioned already - you are looking for the unallocated space to the right of the 4th partition.  That is what you want to claim.

                                                  4.  Click on the 4th partition to highlight it.  Then go to the menu at the top and click "resize".  I am doing this from memory, so I might not have the commands exactly right.

                                                  5.  Click on the up/down arrow in the box to increase the size of partition 4.  Max it out and make it as large as you can.  Click OK or Save, whatever the option is.

                                                  6.  Go to the top of the menu and click "APPLY".  None of your changes will be committed until you click "apply".

                                                  7.  After it is complete (wait for a dialogue box to appear saying the actions are complete), close the program and eject your SD card properly by right-clicking on the drive letter in Windows and select "eject".  Do not remove the SD card from the PC until Windows says it is safe to do so, otherwise you could corrupt the files on the card.

                                                  8.  Insert the card into your Nook (power is off!) and turn it on.  It should boot right into Android!  To boot back into Nook mode, you have to be in Android mode.  Press the power button and select "reboot".


                                                  Have fun with your Android Tablet!

                                        On the AndroidForNook site, in the FAQs, he says that he's hit several NT16s that require either being plugged into the wall charger or a PC to boot into Android. So far, he hasn't found any differences between them and others which work. He also hasn't found a way to get any of them to boot to Android without being plugged in. Sounds sort of like a hardware or firmware change to me. It would be interesting to know when those were manufactured compared with the ones that boot 'normally'. On the other hand, one would think that, if that were the case, all of the NT8s would act that way unless they discovered the 'fix' after the NT8 manufacturing run was ordered. It does make me lean more toward doing it myself or paying AndroidForNook $10 than spending $50 or more on N2A, only to find my NT 'fixed' on the next update that I don't block.

                                                No, "booting from an SD card" and "rooting the device" are not the same. Booting from an SD card means you're running an entirely different operating system on the Tablet via the card. Rooting the device means you've changed the internal coding of the device to make it do what you want it to do.

                                                 

                                                CM7 is a popular (maybe the most popular) operating system the rooting community uses on the Nook - either through rooting or a bootable card.

                                                 

                                                Android for Nook provides files for making your own bootable SD card.

                                                 

                                                I think bootable SD cards are usually still usable after a software update. Rooting is usually undone.

                                                 

                                                And if I'm wrong on any of the above, I'm sure someone will come by and let us know. :smileyhappy:

                                              I've been using a Sandisk 16gig class 10 since November and it works fine. There have been some bogus ones offered online, though. Class 10 cards are designed more for video, moving large, sequential files quickly. But trying to run an operating system from the card requires loading smaller, more random files, and seems to work better with class 4 cards. Several people have reported that they show videos fine, though. Actually, the class designation is more concerned with the WRITE speed than the read speed, so higher classes are recommended for video and D-SLR cameras.
