I installed ubuntu over a W8 installation (my objective was that only ubuntu remains), the installation completed well and ask to reboot, after that, it only gives me a black screen and
grub rescue>
appeared on the screen. I tried to follow the guide from here: Fixing GRUB error: “error: unknown filesystem” I was capable of finding the .mod files, but a series of issues emerges.
*If found the files in (hd0,gpt5), is the "gpt" a concern??? * after setting
set prefix=(hd0,gpt5)/boot/grub
and trying to load the module
insmod normal
computer says:
error: file '/boot/grub/x86_64-efi/normal.mod' not found
I dont know why it adds the extra 'x86_64-efi' in the directory. Given that the solution doesnt work, I tried loading the module with the complete directory:
insmod (hd0,gpt5)/boot/grub/normal.mod
But this time computer says "invalid arch-dependent ELF magic". I havent been myself capable of advance more than this on my own, please help.
UPDATE
I was capable of run "try ubuntu" from the live usb, I can see all my partitions, the partition with the ubuntu files, the partition with all my data, I would only like to know how to make that ubuntu starts on reboot, nothing else, please help.
