I am a little lost.
So, I have a dual boot Win10 / Ubuntu 14 (I think), but it's getting old. The Ubtunu score is basically made for, I had to give Frankenstein more space for a computer project and he now thinks that it is encrypted. In addition, I have a connection loop problem and I have not been able to solve it.
I am now on vacation, so I have time to do a relocation, and I would like to erase everything and start over. I have a USB key with Ubuntu 18, but I have some problems: I tried to boot from the GRUB command line (as a result of this great tutorial that worked once ) but I am stuck at the point
search --fs-uuid --set = root UUID step. I get "failure to read sector 0x0 on partitionX" and "none of these devices: UUID" (I'm sure I've got the right UUID since
ls (partition) give it to me and tell me that it is Ubuntu 18.
I have therefore tried to work around it and use the BIOS to try to boot on the USB, but I have an Acer and I do not know how it happened, but he now has a password that I do not know (I've been looking for this and I've seen no solution that does not require me to dismantle this damn thing).
Do you have an idea of what to try next?
