After I rebooted, I got a black screen with GRUB, asking for commands.
How do I access my desktop so that I can use Boot-Repair to repair, reinstall and fix GRUB?
Minimal BASH-like line editing is supported. For the first word, TAB
lists possible command completions. Anywhere else TAB lists
possible device or file completions.
grub> ls
(proc) (hd0) (hd) (hd0.gpt3) (hd0.gpt2) (hd0.gpt1) (hd1)
grub>
