I installed ubuntu in my computer a few weeks ago, and I was using it through dual-boot (I have Windows 11 and Ubuntu) without any problems. A few hours ago, I turned on my computer and this error appeared:
"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"
I changed the boot order from F2 and I put Windows first, and now my computer run Windows without display the GRUB screen. I changed again the boot order and the same error still displaying.
Also I've tried connecting my USB with the Linux ISO but when I open the Boot Menu (F12), I have only 2 options: Ubuntu and Windows, not my USB device. If I choose Ubuntu, the same error is displayed again.
Also I've tried entering "exit" but the same black screen is displayed again.
Any suggestion? Thanks!
