Today, my computer just prompt me with a message like this one:

File not found –set-root –ignore-flop…

Error 15

Press any key to go tot he menu…

Then a GRUB4DOS shit prompted and showed a bunch of options of Windows SLI complete mode, default mode, etc. And a command line

Then i try to boot them all with no success, then tried to run the GRUB comand line and tried to figure it out, also with no success.

Anyone who knows how to fix it, tell me please.

PD I write this on my Raspberry Pi and is very slow
