Black screen


Something strange happened with my PC.

I wanted to copy files from my GrapheneOS, I did use the same pendrive as usually. I did format it on GrapheneOS, then copy file’s. After that just connect to my PC. QubesOS was already running. When I connect pendrive I got many notification about system discontent USB device’s.

Keyboard and muse got discontent by system. I don’t know why, I don’t understand. I pulled out pendrive but nothing changed. Without choice I turned off my PC by power bottom. Then started the machine again. Now it does not boot to the system. Only black screen.

Computer is restarting by itself the only option I have it is picture: blue screen I can choice system. I don’t know what to do?
Can it be fixed?

I did not change anything in BIOS.

When you have the boot-screen (“Qubes, with Xen hypervisor”)

  • hit e to edit the config
  • locate the quiet keyword on the kernel-line and remove it
  • Press Ctrl+x to boot in verbose mode

Check the errors that you’ll see on the screen and try to search them on forum/github issues.

Like those? Is this what I should check?

Yes, then search for messages and you’ll find this issue:

And possible fix to boot older kernel (or chroot from LiveCD) and regenerate grub config and initramfs.
