This is an (hopefully) updated collection of all roms (not android based, but other linux OS, like ubuntu, archlinux, fedora...) for nexus 7 (grouper and tilapia) available using the MultiROM system.
MultiROM is an amazing hack (I want to thank again its author, Tasssadar) that permits to boot different OS (multiboot) and different android roms. It starts between kernel and rom init, showing a sort of bootloader dialog to choose which system to boot.
It supports installing (and booting, of course) roms to USB drives.
To use MultiROM you need multirom installation zip , a modified TWRP recovery and kernels with kexec support. Relax, is not hard or long to do this.
More information and installation (of MultiROM, recovery and kernels) --> [ MULTIROM ]
PS: I need to specify I coded nothing, my only work was helping with issues, repacking roms, make them work. I want to say thank you to all devs are developing for Nexus 7, I'm doing this because I appreciate their work and I want MultiROM to rise. It deserves to.

HOW TO INSTALL A ROM.
Tasssadar provided also a zip template (see the [ WIKI ] for more info) that is incredibly easy to use.
To install a linux os to sdcard, you just need to download the zip and flash it like a normal update.zip.
It won't replace your internal rom, because it is going to install in /sdcard, not in /system or /data. And it WON'T wipe anything.
Remember that flashing ubuntu or android rom is DIFFERENT from flashing those zips. To flash ubuntu or another android rom you need to use MultiROM menu under ADVANCED voice in recovery (again, see wiki or multirom thread if you need more information).

ROM PACKS.
In the next post I'll share links for rom zips. If you have other zips or if you have built other zips, please share them. They will be (hopefully) added to the list. If not, please pm me. I can't read all posts.
If you want to share a zip, please try it first. I don't know if I'll be able to test everything real-time, and I don't want anyone to see his sdcard erased or strange things like this. MultiROM has a percent of risk, but nobody has lost his data till now. So please share zips consciously.

PAY ATTENTION: NEW MULTIROM CHANGED THE ROM ZIP STRUCTURE!
NEW STRUCTURE HERE.
I GUESS YOU CAN USE OLD ZIPS, BUT I CAN'T TRY AND IT'S BETTER TO USE NEW METHOD (REPACK NEEDED)


STEPS TO CREATE A NEW ROM ZIP (EASY-WAY):
* first, download the template (reworked by me)
* then, unzip the template, put the root.tar.gz and rom_info.txt inside rom folder (if you don't know what I'm talking about, read again the wiki - link above)
* edit rom name inside of scripts/extract.sh script (it's the only thing you have to edit, unless you want it to do something else, but be careful in that case)
* select the 3 folders (META-INF, rom, scripts) and zip them in a zip called <DISTRONAME>-MultiROM-Installer-<VERSION>.zip (I think it's a good standard, if you don't like simply name it another way, but I reckon that using a standard would be a very good thing)
*when the zip is finished, upload your zip somewhere (I use google drive now, but I hope I'll have my storage sometime in the future) and share the link here. I will add it to the list.
If I don't, pm me.

[EDIT] new packing method for webos available https://github.com/Tasssadar/webos_multirom_packer [/EDIT]

The rest is up to you.
Enlightenment is preinstalled in build 20130113-2.

UBUNTU TOUCH.
infos: use MultiROM Manager app to install it.

Hi xela,

I understand the process except for creating the 'root.tar.gz' file from a compressed image (.img or .raw) file. Do you need to extract the image file to the /root folder and then recompress with a command similar to:

sudo tar --numeric-owner -zpcf root.tar.gz ./*

Nice Topic, i've tried your first Bodhi Zip and it seems very fast and stable to me. A few bugs, but nothing major.
I'm waiting for the new Version to finish uploading :)

I couldn't find out how to mount those IMG files. I thought they were ext4 fs but they aren't. I tried to use dd to flash them on a drive but failure again. So to extract rootfs I install them with standard procedure (Ubuntu) and the repack roofs to tar.gz. It could be useful to find out how to directly extract rootfs, because it's the same method used by Ubuntu. With the difference that Ubuntu uses zsync to permit fast upgrade...!

I could never get it mounted as well.... Is this why your having a delay in uploading the new bodhi release?

If you can get the files from the .img files, you really dont need the zip to install it, just creat a dir with the name for the OS, then inside create a dir called root, then inside extract the .img

For the rom_info.txt file, just make the changes needed and put them on the same dir that ../root is and restart and you should be able to boot form it.

Unfortunately we have been unable to mount/extract anything from the image although it appears it may install via the multirom/ubuntu method

I think zip solution is the best and most "standard". When I make a zip I know it will work, because it's the final, multiROM surely compatible, version. And I can test it immediately, fix it, reflash, and try without messing the world up. I think update zips are the most user-friendly way too. But that's only MHO.

    Ubuntu touch preview
    Okay, I'll skip right to the instructions.

    0. Requirements
    You'll need MultiROM installed with recovery from at least 22nd of February. You can find downloads and installation instruction in in MultiROM's thread, as soon as you have it all installed, come back to this post.
    Free space needed: a little over 1 GB.

    1. Downloads
    You'll need two ZIP files from this daily build page.
    Base system: raring-preinstalled-armel+grouper.zip (~33 MB)
    Ubuntu data: raring-preinstalled-phablet-armhf.zip (the biggest one, ~550 MB)

    2. Installing base
    Reboot to recovery and got to Advanced->MultiROM. Select "Add ROM" option. Choose these settings:
    Choose ROM type: Android/Ubuntu touch
    Share kernel with Internal ROM: Don't share
    Install location: Wherever you wish to install it.

    Click Next, then select ZIP file as ROM source, and choose the smaller ZIP file with base system (quantal-preinstalled-armel+grouper.zip). Proceed with installation. Do _not_ reboot after installation!
    Installing on USB: if you get to screen which wants you to "Set up the size of disk images", set the size of data.img to something bigger - 1500mb should be enough.

    3. Installing Ubuntu data
    Select List ROMs in MultiROM menu in recovery, then select the ROM you've just created (probably named something like quantal_preinstalled...) and choose Flash ZIP option. Select the bigger ZIP file (quantal-preinstalled-phablet-armhf.zip) and flash it. Beware, this ZIP file then can't be used to flash Ubuntu without MultiROM, as it is modified in the process to suit MultiROM needs.

    5. Profit
    Ubuntu touch developer preview is now installed. Keep in mind that this _really_ is just a preview, so pretty much nothing will work. Looks good though.


    Not much is changed, the only thing which needed to be done was to compile Ubuntu's kernel with kexec-hardboot patch. The mrom_quantal-preinstalled-armel+grouper_20130221.zip file has only different boot.img, otherwise it is exactly the same. You can use official daily builds, the patches for MultiROM are in there.

    This preview is basically cyanogenmod with Ubuntu UI running in chroot, so it is really similiar to Android. I'm told that this is because the Ubuntu core and, most importantly, drivers, are not yet ready. In the future, it should be this UI running on top of standard Ubuntu core (ie. the Ubuntu raring which you already could multi-boot).

    This is an (hopefully) updated collection of all roms (not android based, but other linux OS, like ubuntu, archlinux, fedora...) for nexus 7 (grouper and tilapia) available using the MultiROM system.

    In the next post I'll share links for rom zips. If you have other zips or if you have built other zips, please share them. They will be (hopefully) added to the list. If not, please pm me. I can't read all posts.

    If anyony wants to use these instructions to get a kde desktop environment for Arch linux, then here they are. I have not included the kde login screen yet. still just using startx... Have not gotten gnome up yet, and lxde was stuck in portrait and non responsive.

    These instructions assume you are using a usb kb and mouse, via otg.



    Install tassader's mrom packed Arch.

    Boot arch

    at login, user:root Password:root

    type wifi-menu. when window opens, pick your wifi, and enter security pass, if needed.

    once back to cursor, type "pacman -Syu" to update the whole system. Confirm and Y (leave out the " ")

    once back to the cursor, type "pacman -S xorg" Press enter for all, and Y

    cursor again Type "pacman -S xorg-xinit xorg-twm xterm" confirm, and Y

    Here, there are two options--

    1. Edit /etc/X11/xorg.conf using nano from arch.

    Or

    2. Reboot (type "reboot") and boot android. Using a root browser, navigate to /data/madia/0/multirom/roms/your arch install/root/etc/X11/xorg.conf. Edit xorg.conf in the same way that @ylixir described in the post just above this one. Save changes. Or, just download from here http://db.tt/rR1BSvbQ and replace your existing xorg.conf with this one. I recommend this method for people not comfortable with terminal style editing, to help prevent parse errors from incorrect edits.

    Reboot and boot into Arch.

    Now, add a user acct for yourself-- "useradd -m -g user -G wheel,storage,power -s /bin/bash usernamehere"

    Now a password-- "passwd usernamehere" enter password twice

    On to Kde-- "pacman -S kde" Press enter for all, and Y

    Once done, at the prompt, type "cat>> .xinitrc" It will now drop down a line. Type "exec startkde" Now hit ctrl+D twice. Makes me do it twice, anyhow.

    Now after all that, type "startx"

    You will now boot into kde desktop, but it will be in portrait. Using your mouse, click the kde bubble in the lower left. Click applications. Go to settings. Then system settings. In the category "Hardware", click display and monitor. Under the rotation dropdown, choose turn right 270 degrees. Click apply. then click save as default, and click the same in the dropdown. Click ok on pop up confirmation. Your desktop will now be set correctly, and should boot with the correct settings from now on. Have fun!

    Thanks to ylixer for the xorg.conf edits he posted. Most of this info was hobbled together from an arcticle about installing Arch to a raspberry pi.
