I attempted to install Debian 11, using a live iso. Attempting the graphical installation fails, as it states “undefined video mode number: 314” Seeing video models available finds nothing, while pushing space to continue simply leads to a freeze. The text-based install also fails, simply freezing. I can enter the live environment and see a graphical desktop (Mate) and attempt an install. At first this works; however, it ends in failure with a message comparable to this: “grub-pc has no installation candidate.” Given that I’ve wiped my hard drive, attempting to boot from the hard disk leads to the error “file `grub/i386-pc/normal.mod’ not found. Entering pc rescue mode” .
I found someone on Reddit has an identical issue, but sadly no one has answered their question.
Thank you for your help!
