Disk boot menu entries disappeared from the BIOS Boot menu [Dell 5521 - InsydeH20 (A05) - UEFI & secure boot activated]
Hi,
I got a DELL 5521 a few month ago, I use Windows 8 preinstalled and Ubuntu 10.04.3 LTS using UEFI and Secure Boot on and everything was fine.
Suddenly, without any reason I am aware off, when I power-on the laptop, the BIOS boot menu does show the disk boot entries anymore, which was Windows 8 and Ubuntu.
The hard drive is ok, I have been able to boot an Live Ubuntu using a USB stick and access the hard drive data.
I have tried the "Add boot option" item in the BIOS, I select the disk partition, and then entered "/EFI/ubuntu/shimx64.efi" as the file path
but it does not seems to work.
How can I repair the BIOS boot entries to be able to boot Windows and Ubuntu again ?
Configuration:
DELL laptop 5521 (i5-3337U)
Insyde H20 Bios version A05
UEFI and Secure boot activated

Ubuntu 10.04?
Don't you mean 12.04?
Anyway, try RescaTux.

Finally, I have been able to shift the Linux boot to legacy bios boot using boot-repari x64 after creating a boot partition
