Hello there,
I have been running Unraid on my server for about two years now and today I tried switching to Unraid on my desktop computer.
When I choose the Unraid USB flash drive from my motherboard's boot menu, the screen goes black for one second and then sets me back at the boot menu.
My hardware:
MSI B450 Mortar Max (BIOS ver. 7B89v2C, 2021-02-01)
AMD Ryzen 5 Pro 4650G
AMD RX 5700 XT
AMD RX 550
SanDisk Cruzer Fit 16GB USB 2.0 (same model that works fine on my home server)
Things I have tried so far:
reflashing the USB drive, both with the Unraid installer and the legacy method (on Windows 10 as well as on Arch Linux)
different USB ports
different USB flash drive
booting with and without dedicated GPUs installed
disconnecting all SSDs
booting with a Ryzen 5 3600 + dGPU
I spend all day trying different hardware combinations and BIOS settings, without success. I'd be thankful for any suggestions.
