Hello all,
I have an apparently niche problem with my MPG X870E board that I can't solve with my own experience or Gemini/ChatGPT help. Maybe someone went through the same thing or has extensive knowledge about it.
I have;
- MSI MPG X870E Carbon Wifi board,
- Ryzen 9800X3D CPU and a RTX4090,
- 2x Samsung 990PRO 2TB and 1x 4TB of the same.
Lets give the drives a letter for future reference:
A: 2TB with Windows installed on M2_1
B: 2TB (recently with Linux installed) on M2_2
C: 4TB non bootable storage only, installed on M2_4 (probably kinda irrelevant but still)
When I had only Windows on Drive A, everything was perfectly fine. Then I wanted to give Linux a shot and installed it on drive B just not to mess up anything with partitioned dual boot. Boot order was A > B all the time and nothing broke.
One day, I decided I was satisfied enough with Linux and changed the boot order to B > A just not to go through boot menu and BIOS password every time I reboot. After save and exit, the M2_2 (B) drive was not even detected by BIOS anymore.
I updated the BIOS, it showed up again, then applied some fine tuning settings recommended by AI (like force Gen4 and 8x+4x+4x etc) and tried B > A again. Same result, it went away.
No amount of CMOS reset or hard-flashing the firmware using the back port&button helped after that.
I've swapped the physical positions of the A-B drives, now I boot into Linux, but the M2_2 (now Windows) drive is still not detected at all.
I downgraded the BIOS and re-upgraded it, it worked briefly, but it went away again. This time I didn't even change anything in BIOS settings, just checked it in BIOS, then rebooted.
Any ideas about how to fix it, and why/how it never happened for years before these turn of events, is greatly appreciated.
❤️
