You can flash a new boot image with a custom init redirecting continued boot from a root partition on the SDcard.
I do that in order to run GNU/Linux Debian.

Thank you.
That is what i want.
Is there any existing bootloader can choose to boot from SD card?

Have a look at the init I'm using the achieve this.
http://whiteboard.ping.se/Android/Debian#init
You might want to read the rest of that web page as well, to get some idea about how to implement it. Also note that this isn't a bootloader, and you can not replace the kernel, only the root file system. The kernel is the one booted from the internal storage (but you can of course replace it to whatever kernel you'd like, but you can not boot different kernels using different SDcards, as you would using a bootloader).

Boot Manager on Xperia Play

I found, today the Boot Manager app that allows you to have up to 5 Roms on your phone at once but I dont know how to set it up on my phone. Would love if someone would tell me how to set all the variables correctly, so I can use it

Having 5 ROMS installed on our device would never work. At most you could have 2, with very limited space.

Ok I get that but the they run off your sd card and I dont care I just want to set it up and get it running, how do I do that?
I would like to know how to get this working on the Xperia Play too.
Thanks

No. Isn't the boot partition filled up with 1 rom.
Running from SD card would be way too slow so I don't think it'd work

it does not work because to boot from the SD card the ramdisk needs to be edited, ramdisk goes in boot partition which we can only write to with fastboot.

[Q] Why is Ubuntu not possible on B80-B90?

I haven't read too much on the install process, but if I understand correctly it replaced recovery by flashing a kernel to it. Is there any particular reason that we can't use something akin to RecoveryInstaller to install an Ubuntu kernel that will read off of our Micro SD card partitions since it still installs an image to recovery?

It doesnt read off the micro sd it reads off internel sd
B80 B90's dont have nvflash nvflash is used to re partition the internal memory to make enough room for the ubuntu install aswell as other things
On a b80-b90 you can do chroot ubuntu through a micro sd and vnc viewer but its slow same with replacing the recovery and reading it from micro sd the method you are talking about has been done through flashing .zips to acces ubuntu or android but it was slow and not as safe.

Why not make a kernel that mounts the micro sd card as the system then and flash that kernel to recovery? Surely it's possible.
it's of no great importance,through explore we can make the home for the SD.

that's the easiest part, just edit the fstab and will do it, but just as they said before ju can't install ubuntu native if you can't use nvflash.

Why not flash the Ubuntu kernel over the Android kernel then if you only want to run Ubuntu on your transformer? You get to keep recovery and the Android system is still there in the event you want to flash an Android kernel to return to the stock system.

run Ubuntu from SD card ?

Hi,
I want to run Ubuntu on the TF101 but without touching the Android partition and losing anything from the current ROM installation.
Would it be possible to install Ubuntu on external SD card and run through boot with a custom bootloader ? (dual boot maybe)
I've searched for a thread for this but there are several Ubuntu threads on the development forum and most of them run Android with a different partition table on internal SD card.
Thanks.

I'm pretty sure it can't be done like that. It either replaces recovery or you do the pseudo dualboot.

I think this is what you are looking for. It's the Dualboot over external micro sd section
doing that is pretty straightforward, you just need to partition the external sd and pass the right parameter to the kernel while booting, but you still need to flash a secondary kernel ( hopefully on the SOS partition of your internal mmc ) so u will not actually get a *clean* dualboot.
It probably worths only if u wanna easily edit the rootfs content without using nvflash so much ( which u need anyway at least for the initial kernel download ).
An other advantage is that if u're planning to make lots of tests ( apt-get install *this*, autoremove *that* ... ) u will save ure internal hd a lot of read/write cicles getting some years more for ure device to live..
I did it on my B60 using OLiFE scripts, just edit the ./boot/dualboot.cfg file replacing the "root" kernel parameter with whathever partition u want ( probably blk1p1 on the simplest configuration ), format ure external ssd as u need ( you can do it right from android with a terminal emulator and fdisk/parted ), copy over ure new root partition the rootfs content of ure choise , flash the "edited" kernel with OLiFE and enjoy.

[Q] HTC ONE X - Recovery Help

Ok, I have a problem very similar to threads Ive found by with some minor differences. Hoping for some answers to this nightmare....
I have an AT&T One X - unlocked, rooted and flashed. I was running Viper XL and using TWRP recovery 2.3.10. Yesterday, I decided to flash a Liquidsmooth ROM using flash image gui......everything went fine with install until it hung on liquidsmooth boot screen, for an hour. Figuring there was an install error, I rebooted into twrp to do a recovery. Recovered back to Viper XL and was thrown into bootloop - HTC screen/Viper Boot...over and over again. Finally decided to stop before I destroyed anything.....so here's where I am now. The phone has been reset, sd card was wiped but I can still boot into TWRP without a problem. However, now there is no backup or ROM zip on this SD card.
So my guess is that first and foremost I need to get a ROM on that SD card, however (I'm on a Mac) when I plug the phone in, I get a "No Android Device Connected" in the dialog and when trying to mount SD card via TWRP, the "Mount SD Card" box wont tick.
If I view the log file in TWRP I see a lot of 'could not mount SD card' errors.....
I don't want to keep screwing with it and make things worse. Considering this has happened with both CM10 and LiquidSmooth, my guess is I should just stick with Viper for now, so any help getting this back on here would be hugely appreciated! I have no access to a PC, only a mac.....
Boot screen info:
TAMPERED - UNLOCKED
EVITA PVT SHIP S-ON RL
HBOOT-1.14.0002
RADIO-0,19as.32.09.11_2
OpenDSP-v29.1.0.45.0622
eMMC-boot
If you're on Hboot 1.14 and are S-On you need to manually "flashboot flash boot boot.img" in fastboot from the bootloader menu whenever you flash a new ROM. Go to the bootloader and click "fastboot" then plug in your USB connected to the computer and it should now say "fastboot usb" assuming your drivers are installed (it might install them after you plug your phone in). Now you can flash the boot.img from the rom zip manually via the fastboot command window.
EDIT: Sorry didn't realize you were on Mac. I would first figure out how to mount the SD card as removable storage and not an Android device. You may have to format it as a file system first. At least that's what I had to do when this happened to me when I first flashed but i'm on Windows. I should of read your post more thoroughly.
So this would be done from the terminal? I was able to boot onto fastboot, connected USB cable and now show fastbootusb. I downloaded the ViperXL rom again, so I should extract the boot.img and flash this via terminal?
Are the commands the same on a mac? And how do I then get the rom onto the SD card?
Am I correct in my assumption that this is the answer? http://forum.xda-developers.com/showthread.php?t=1693372

I don't want to give you too much advice since I don't have a mac but I would assume they're the same except you need to have fastboot/adb on your computer but since the ones I have are .EXE files they're not going to work on OSX. However, If fastboot usb came up the computer is reading the phone so you may be able to open the SD card as removable storage on you computer thats how it is on Windows. So once you do that you can just move the ROM zip onto the card. But, like I said you're going to need to figure out a way to flash the boot.img separately or else you won't be able to boot into the ROM when it's installed (you'll just bootloop). You're going to have to do that with every new ROM you flash if you're still S-On.
Wish I can be more help but i'm not that versed in OSX.
you can use [APP] Flash Image GUI - Flash Kernels and Recoveries from normal Android mode! to flash boot.img fine before flashing the rom. it will search the rom zip for the boot.img and flash it. you can also flash recovery using the app also. some roms place boot.img in other locations other then the root of the zip in which case you might have trouble selecting the whole zip, but you can just extract the boot.img and flash it fine.

No problem - thanks for the help you can offer. It seems my bigger problem is getting a ROM onto the SD card - Ive read several similar threads and from what I can tell, doing a factory reset through TWRP means I need to reformat the SD card, which is why it wont mount. Does this sound reasonable?
And if so, is it as simply as "Wipe external storage - SD CARD" in TWRP?

And yes you will have to reformat the SD card I don't know how to go about doing it OSX though. I'm sure a google search will help. The method should be the same for any type SD card plugged into OSX. But remember flashing the boot.img will be the other issue.

doing a factory reset in hboot corrupts your sdcard.
once you get adb/fastboot working try running "fastboot erase cache" that clears out the part of cache where the settings for twrp reside, that is why when you format cache in twrp you always see 16MB when you fastboot erase cache it goes to 0MB but for recovery to store it's settings you need to rewipe cache and dalvik in twrp.

I think my inner idiot is kicking in. I believe I already have fastboot installed - perhaps Im missing something. I went through this process before and have all of these same files still on my desktop. I'm able to boot my phone into the bootscreen (white screen) and TWRP without problems....the only issue I have right now is my SD card and getting a ROM pushed to it. I've gotten two conflicting bits of advice that im reluctant to try....one of them states I should just boot into TWRP and do a "Wipe external storage" and the other one says I should format it using disk utility in OSX. When I boot into TWRP and hit "mount", Im given four options, mount system, mount data unmount cache and mount sd card...the ONLY one I cant select is mount sd card.

Not sure what you should do really this happened to me but I forgot what I did. I ended up just formatting the card with the disk utility in Windows but I don't remember if I had to re-flash the recovery or not afterwards.
So I should just use this method again, regardless of whether I may have done it before, correct? This will format in stock recovery?
In the APK folder, there are two fastboot files, one 'fastboot' and one 'fastboot-mac' - i want the -mac one obviously, right?

Mac-Pro:android originalseven$ ./fastboot-mac devices

So it's showing a connection between phone and computer.......
The next logical step would be....format the SD card?

[Q] Can't flash from SD Card

Good evening, XDA :cyclops:
I am having issues flashing from recovery!
Some device info: Motorola Xoom WiFi, fully stock and fully updated, unrooted, bootloader unlocked today, device wiped multiple times. This is my first day trying anything custom on this device.
I decided today that i wanted to go custom on my Xoom today and update it to KitKat via this method.
I have downloaded all the required files per the mentioned guide. While in recovery i go to apply update from USB drive, but it is not finding any of the downloaded files from the guide.
What I see is
Code:
Android system recovery <3e>
Choose a package to install:
/sdcard
../
The ../ is my only option to click and it obviously returns me to the main recovery menu.
All the zip files are on the root of the SD card, not in sub folders. I have confirmed via PC and another phone that the files are indeed there. I tried with a different, fresh, formatted (fat32) SD card, but I'm getting the same results.
The Xoom is indeed reading the SD card, confirmed via settings>storage.
I've tried using adb, but it's telling me the image isn't correct, but it's certainly possible I'm missing a step with adb.
Code:
C:\Xoom bootloader unlocker2>adb reboot bootloader
C:\Xoom bootloader unlocker2>fastboot flash R.A.H._TWRPv2.6.3_BigPart_selinux.zip
unknown partition 'R.A.H._TWRPv2.6.3_BigPart_selinux.zip'
error: cannot determine image filename for 'R.A.H._TWRPv2.6.3_BigPart_selinux.zip'
Yes, the zip is in that folder. I thought maybe I'd root first, so I tried that method with the root zip, but I'm getting the same error.
Is there something I can do to repartition this device and get it rommed, or am I doomed to use it stock?
Thank you for your time!
I found some information stating that I need to enable the SD card, but since I'm running up to date SW, and I can see the SD card from settings, I'm assuming that this isn't the case, correct?
I'm still stuck. Anyone around who could give me some advice?

It appears the XOOM does not like SD Cards that were formatted using Windows
(or perhaps Quick Formatted using Windows).
Using a 4GB FlashDrive formatted as Fat32 using Linux (i.e. Linux Mint 17.3 Cinnamon 64 bit boot CD)
resolved the issue.
