After the installation of Mageia 9 my Dell laptop refuses to boot with the following error: “No bootable devices found”
Background: Before, Ubuntu 22.04 was installed on the laptop. But I erased it completely and rearranged the partitions, too.
Solution
Manually create a boot option using the DELL setup utility (aka UEFI BIOS):
- Press F2 to open the setup utility
- Go to: General | Boot Sequence
- Under “Boot list option”: Make sure UEFI is selected
- Click on “Add Boot Option”
- Enter a meaningful “Boot Option Name”, e. g. “Mageia 9”
- Click on “…” to select a file name
- Navigate to \EFI\mageia\grubx64.efi
- Done.
Further information
In the setup utility, I have Secure Boot disabled.
An official Knowledge Base Article of DELL recommends to set System Configuration | SATA Operation to “AHCI” for linux installations. Unfortunately, mine is set to “RAID on”. Maybe that is causing the issue…
