Ubuntu Studio 24.04 LTS KDE Plasma, sobre portátil Samsung del año 2012, BIOS, arranque DUAL
Problem Description:
Instalación correcta de ubuntu, corrección arranque con boot-repair, amdos SO en UEFI (no Legacy). Aparece el grub, pero la pantalla de opciones está vacía; tocar cualquier tecla da entrada a Ubuntu. Solo puedo arrancar Windows 10 con USB de arranque. paste bin no refleja nada incorrecto (creo) ¿Puede existir alguna incompatibilidad entre SO?
Please supply the link to your boot-repair report.
Thank you for posting the link, this is all we need.
I deleted your next post because it is almost impossible to read and analyze such large blocks of text.
Thanks for understanding.
Line 44:- Boot000A* Ubuntu HD(1,GPT,477c721f-fdce-42d8- bd31-9f06941d942f,0x800,0x219800)/File(EFIubuntushimx64.efi)
This ESP (Efi System Partition) entry does not seem to be correct. The back slashes are missing.
Line 169:- SecureBoot disabled - This system doesn't support Secure Boot.
The efi entry should use grubx64.efi
Can you boot into Ubuntu and change the efi entry as follows:-
Boot000A* Ubuntu HD(1,GPT,477c721f-fdce-42d8-bd31-9f06941d942f,0x800,0x219800)/File(\EFI\ubuntu\grubx64.efi)
If you have not manipulated ESP entries previously, here is a link
efibootmgr
After you have edited the efi entry, also run sudo update-grub
Ah, I’ve just noticed that the ESP entry was changed after the repair
Line 183:- Boot000A* Ubuntu HD(1,GPT,477c721f-fdce-42d8-bd31-9f06941d942f,0x800,0x219800)/File(\EFI\ubuntu\shimx64.efi)
Anyway, change the shimx64.efi to grubx64.efi - it may allow the grub menu to appear?
Gracias. Ya localizado el archivo en sda4 File(\EFI\ubuntu\shimx64.efi), pero ignoro cómo modificarlo con nano (nano no encuentra el fragmento “shimx64.efi”).
efibootmgr is the tool to edit efi files.
I included a link to a useful guide in post no. 5
