We haven't tested this and it's likely that bad things will happen. Do you have any logs that can help us diagnose the error? (dmesg, logcat, TWRP log)?
Can you:
1) Flash the latest MultiROM zip
2) inject the boot sector
3) boot into your primary.
4) get a dmesg
The dmesg contains MultiROM's logs and will help us diagnose the issue.
Here is a dmesg log. http://pastebin.com/WksnFDb0 edit - this was taken directly after trying to swap primary and secondary roms. Hope it helps.

The recovery dmesg doesn't seem to show anything weird: when does swapping ROMs fail? Can you grab the TWRP recovery log (it's on /cache, I think) if it fails in the recovery, or /sys/fs/pstore/console-ramoops after a reboot if it fails on bootup?
here is the console-ramoops https://drive.google.com/file/d/0BwP1hSe-Z6szZ1hOSUFoN25RR2c/view?usp=sharing here is the log https://drive.google.com/file/d/0BwP1hSe-Z6szYTktdm1HZXNmOTg/view?usp=sharing here is the last_log https://drive.google.com/file/d/0BwP1hSe-Z6szM0l2aU56Wk5tSkE/view?usp=sharing The funny thing, that since upgrading multirom and recovery to stable from beta4 i believe this was the fourth try for me to swap roms. I can say that this time it worked. Logs anyway, in case they mean anything.. thanks.
I'm new to multirom so forgive my ignorance, I used the market app to install multirom the recovery and the kernel. But it's showing that recovery is not installed however I do boot into multirom/twrp recovery when I boot recovery.. Should I worry about the installer app not showing as installed?

Same here. Then when I choose the secondary ROM in the app, it gets to the Google screen and appears to reboot into the primary ROM without any other options during startup. Tried a few different ROMS, gapps, kernels as both primary and secondary. :/

I would manually install beta 4 as in the OP and just use the app to switch ROMs for now. It shows recovery not installed for me too but it's working just fine.

I've done the manual process as well but don't get the boot menu to choose which Slot to boot. I have tried both Franco and stock both kexec patched. Same result.
Flash the installer zip in recovery and download the app from the Playstore. Also try EX kernel.
Done, done and done. Same result, no boot menu.
Glad I'm not alone. Same here. I haven't given up yet!!

Sorry I'm not more help. Only other thing I can think of is that I had the debug app installed and the beta 4 zips then installed the updated app from the Playstore over that. I've got 10 ROMs installed including a stock unrooted and two CM builds.
Anyone else running DU as secondary with latest elementalx kernel (1.11)? After flashing the kernel to secondary, the ROM refused to boot, instead rebooting straight back to recovery. Definitely a kernel problem as flashing 1.10 returned everything to normal. Just checking I'm not the only one.

Check the SElinux status of ROM and kernel, they must be compatible
Yeah I did, including switching between enforcing and permissive just to double check. I'll give it another try at some point, not that big of a deal.
I wish I had that kind of time to test all those! I miss the icon feature a lot though.FYI Multirom app from the playstore now let's you edit icons. Pointless I know but cool.

Well you didn't get to be a RC by not testing! Up to 10 now lol.

This project is no longer actively maintained, see explanation here.
1: MAKE A BACKUP. Seriously.
2: Downloads in second post. Flash recovery, then kernel, then MultiROM.
3: Any issues: please report at https://github.com/multirom-nexus6p/multirom/issues I won't be reading this thread very often.
Introduction
This is a port of Tassadar's MultiROM, a multi-boot mod for Nexus 6P. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. You can see how it looks on the left image below and in gallery. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs and MultiROM even has its own installer system, which can be used to ship other Linux-based systems.
This is still very experimental!
This has been thoroughly tested with the most popular ROM's for the 6P.
Make backups. Seriously. Please.
Features:
* Multiboot any number of Android ROMs
* Restore nandroid backup as secondary ROM
* Boot from USB drive attached via USB-C OTG cable
Warning!
It _is_ dangerous. This whole thing is basically one giant hack - none of these systems are made with multibooting in mind. It is no longer messing with data partition or boot sector, but it is possible that something goes wrong and you will have to flash factory images again. Make backups. Always.
Installation
We have a custom built MultiROM Manager .apk in the downloads section, feel free to try it! (somewhat untested, please report, even if install doesn't work, ROM name customization, etc. should work fine)
1. Via MultiROM Manager app
This is the easiest way to install everything MultiROM needs. Install the app found in the next post, and select MultiROM and recovery on the Install/Update card. If the Status card says Kernel: doesn't have kexec-hardboot patch! in red letters, you have to install also patched kernel - either select one on the Install/Update card or get some 3rd-party kernel here on XDA. You are chosing kernel for your primary ROM, not any of your (future) secondary ROMs, so select the version accordingly.
Press "Install" on the Install/Update card to start the installation.
Accept any Super User request prompts.
2.Manual installation
Firstly, there are videos on youtube. If you want, just search for "MultiROM installation" on youtube and watch those, big thanks to all who made them. There is also an awesome article on Linux Journal.
MultiROM has 3 parts you need to install:
- Modified recovery (TWRP_multirom_angler_YYYYMMDD.img) - download the IMG file from second post and use fastboot to flash it.
- Patched kernel - You can use either one of the stock ones in second post or third-party kernels which include the patch, you can see list in the second post. Download the ZIP file and flash it in recovery.
- MultiROM (multirom-YYYYMMDD-vXX-angler.zip) - download the ZIP file from second post and flash it in recovery.
Your current rom will not be erased by the installation.
Adding ROMs
1. Android
Go to recovery, select MultiROM -> Add ROM. Select the ROM's zip file and confirm.
Using USB drive
During installation, recovery lets you select install location. Plug in the USB drive, wait a while and press "refresh" so that it shows partitions on the USB drive. You just select the location (extX, NTFS and FAT32 partitions are supported) and proceed with the installation.
If you wanna use other than default FAT32 partition, just format it in PC. If you don't know how/don't know where to find out how, you probably should not try installing MultiROM.
If you are installing to NTFS or FAT32 partition, recovery asks you to set image size for all the partitions - this cannot be easilly changed afterward, so choose carefully. FAT32 is limited to maximum of 4095MB per image - it is limitation of the filesystem, I can do nothing about that.
Installation to USB drives takes a bit longer, because the flash drive is (usually) slower and it needs to create the images, so installation of Ubuntu to 4Gb image on my pretty fast USB drive takes about 20 minutes.
Enumerating USB drive can take a while in MultiROM menu, so when you press the "USB" button in MultiROM, wait a while (max. 30-45s) until it searches the USB drive. It does it by itself, no need to press something, just wait.
Updating/changing ROMs
1. Primary ROM (Internal)
- Flash ROM's ZIP file as usual, do factory reset if needed (it won't erase secondary ROMs)
- Go to Advanced -> MultiROM in recovery and do Inject curr. boot sector.
2. Secondary Android ROMs
If you want to change the ROM, delete it and add new one. To update ROM, follow these steps:
- Go to Advanced -> MultiROM -> List ROMs and select the ROM you want to update.
- Select "Flash ZIP" and flash ROM's ZIP file.
Note that swapping roms between internal and external is not supported (yet). Also, after flashing a factory image to the primary system and boot partition, make sure to immediately inject MultiROM before first boot, otherwise the secondary ROMs will be deleted.

Issues
- None that are known. If you find one that this thread does not know about/hasn't answered (solid rule, read the last three pages of the thread befre reporting an issue), report it on the specific repo in question here.
- IF YOU GET LOCKED OUT OF YOUR DEVICE: Don't worry! Your data is fine. Simply boot to TWRP, choose 'Advanced' ==> 'Terminal Command' ==> type "rm -Rf /data/system/gatekeeper.*.key" (without the quotes). This is a dirty fix, and should only be used to recover data, not as a permanent solution! After you recover your data, wipe /data (you don't have to wipe Internal Storage), and re-setup the device.
Please report any unlisted issues to the GitHub bug tracker at https://github.com/multirom-nexus6p/multirom/issues . You'll get faster response if you post there instead of in this thread

Extra Information
Unlike some of the other 64-bit MultiROM ports, this port does have kexec-hardboot enabled, which is less risky and speeds up boot into secondary ROM. Anyone porting MultiROM to a Snapdragon 810 device may find the source to be useful. The patch was written by @500 Internal Server Error
Also, due to recent events on other projects of mine, you are welcome to fork our Github repositories, and use them to port MR to new devices, and as a reference, but, I ask that no one build targeting the 6P using our source and post it publicly (of course you can build for personal use, but distribution is forbidden). Of course, I welcome and ask that anyone who wants to pull request changes in to do so!
The only acceptable releases based on our source for the 6P is recovery/multirom themes, though, I strongly ask you tag me so I can note the themed version in the OP.

Version Information
Status: No Longer Updated
Current Stable Version: v33-05282016-STABLE7
Stable Release Date: 2016-05-28
Created 2016-02-12
Last Updated 2017-09-1741UPDATE: I've got all the necessary repos brought up to building in a 7.1.1 tree! For those that don't know what that means, It means that MR is functioning on 7.1.1!
Unfortunately, I've run into an issue. TWRP is unable to bind certain mounts (the most important of which being that even though /data decrypts fine, /data/media/0's bind to /sdcard/ fails for reasons I can't comprehend). This messes up everything else. Hours of debugging have yielded no results, so, I have reached out to some other developers I know in an effort to solve the problem.
If anyone is able to help me solve the TWRP mounts issue, or wants to update multirom_adbd to 7.1.1 (an optional task which I've opted not to spend my time on), they can build In a Lineage/CM 14.1 tree. For those who can help, but don't have the resources to build, my personal builds can be found here: ods.ninja/Server/Android/angler/MR/
I WARN those who opt to use builds from the above, I have intentionally*disabled multiboot functions in them (in essence making multirom useless so the average user doesn't use them). These are only to be used if you are able to help work out current TWRP issues.
Thanks to all, and happy new year.34I will be updating this soon.
I've got most of MultiROM's issues worked out, and was planning on waiting until I had it all fully building with clang/7.1.1 sources, but, I'll concede that those things aren't /that/ useful to the end user.
As of this next release, the recovery will be built in a CM 7.1 tree, and everything else in an Omni 6.0 tree.
If you don't know what any of the above means... you don't need to. Just know that within the next few weeks I'll be posting a new build.2922
Yup. We have 3.0.3-0 working, with a usable theme (like we had previously), and, N-Block encryption (like on the 6P) works, but, we are still working on FBE support for those on the 6P using the option in developer settings, and Pixels... (hint hint).
The MultiROM repo is also brought up to support N.
All that is left is updating multirom_adbd to 7.1.1 so we can get ADB working on the MultiROM boot selection screen, updating Kexec-Tools (and remerging DTB support), then just updating the build system (branches, dependencies, etc.).
