What's your hardware like? Post some information on that as well.
I'm asking this because you may need to match your installation if you're dual booting (UEFI vs legacy install) - I've had some dual boot systems which gave me issues trying to install in either legacy or UEFI while the other OS was the opposite. Some info on any of the errors would help too. Take a screenshot if you must with a phone/camera and post it here (if it's legible).
Converting an existing Ubuntu installation to match the other OS (to/from UEFI/legacy) isn't hard at all, but before we go into that provide the information above.
SecureBoot was also an issue in the past (Windows 8 preinstalls mainly); this also caused some issues and this as well can be "fixed" easily via the BIOS. IF for some odd reason it is a secureboot issue, you will have to update the shim package at least - again, the chances of this being issue are slim to none but it's hard to know without information on the rest of your system and other OS installation(s).
- Ryzen 7 1700
- MSI Gaming Plus B350 (With BIOS that is not officially released yet - problems with RAM)
- 2x4GB Crucial Ballistix Sport LT 2400 MHz
- EVGA 650 B3 PSU
- 1TB HDD
I'm able to install and run Windows 10 on this machine and utilize both GPU's so it seems to be drivers (both standard Ubuntu and AMDGPU-PRO) problem. It can be also Ubuntu itself one.
I use UEFI. Problem with Ubuntu occurs even if it is the only OS on this machine.
I can't point specifically at the GPU drivers from this snippet as essential log files are missing.
You mentioned that this happens with other distros as well so, it sounds like something specific to the rest of your hardware configuration (BIOS) that's not compatible with the stock kernel - or an issue with one of the GPUs or even memory as you mentioned. Again, keep in mind, memory paging or allocation etc is used differently between Windows and GNU/Linux - a lingering issue may not present itself in Windows or vice versa in Linux.
So my suggestions:
1. get a stable memory setup or try different memory if/when possible.
2. use apport (man apport-bug) to report a specific issue to their (Ubuntu) bug-tracking system.
I have several dual Radeon RX (580s and Vegas) systems running on both Debian and Ubuntu with the same drivers; KP's are the least of my worries (haven't encountered them).
I will download latest official BIOS for this mobo and check if it is working (I have installed unofficial one right after stock one, skipping newer official ones)
I have checked following things:
- I replaced memory with slower (so more likely more stable) 4GB 2133Mhz Kingston Hypex Fury - same results
- I have downloaded last official BIOS for mobo and flashed mobo.
- I have tried to update GPU's BIOS but MSI update-software claims that newest is already there.
After 3 days of intensive work, under windows, this set have rebooted (probably Blue-screen but I don't know yet). Maybe Windows logs would give me a clue.
I haven't used apport yet, but I will.
I will use this thread as a public log, of mine trials
So currently I'm sure that it is problem with mobo. I have put both MSI RX570 to new mobo (X370 Gaming plus from MSI) and It works fine. I have put new ASUS RX570 to B350 and problem still exists.

I have also tried to update kernel to 4.10.* and it didn't fixed problem.
Changing grub config solved problem. I had to set
