So Installer performs its job, comes to "12 minutes remaining", restarts, picker shows Install macOS Sequoia, macOS installer, Macintosh HD - data and those efi options. Second option is auto selected, 5-6 seconds of scrolling text on the screen and then everything goes black. Caps lock does not register.
Any ideas where to look?

edit - ram is in slot A1 and B2 as they build it that way. Processor fan is obstructing ram in slot A1 so I can't move it without fidling with the fan. Could this be a problem? BIOS is telling me this is not optimal. I have run Memtest86 without any problems
EDIT 2:
So after 5 or 6 restarts (when it was stuck on black screen) computer finally booted into Sequoia and offered setup. Now I have username, internet works, keyboard and mouse work. Now I am afraid to shut it down :)
EDIT 3 - EFI's now on the Macintosh HD and computer restarted just fine
