No bootable device found. It’s a Dell Latitude laptop (2019)
I started tinkering around with BIOS settings, but so far no luck. When I try to edit the boot sequence, there’s just no disk (unless the Manjaro USB is inserted.)
This laptop has a Toshiba SSD. If you think I should list more of my BIOS settings here, let me know.
I don’t have “fast boot” as an option
Network boot disabled.
“Secure boot” disabled.
“Legacy mode” disabled, doesn’t seem to make a difference.
It’s an option in the installer to erase rather than re-partition. I can mount the internal drive when I boot from the USB, so i see that the installation worked.
That makes me think that your UEFI needs an explicitly flagged partition to boot. Commonly, it is the EFI partition on an UEFI system. Some UEFI’s need it flagged with boot, or esp or boot, esp, some don’t and dynamically discover it on boot time.
EDIT:
Or there was a problem when creating an entry in the UEFI Bootloader which wasn’t reported. You know the UEFI Bootloader loads the file in the efi partition which then loads the Grub Bootloader etc.
Are you sure those are the only partitions it found? Cause it’s saying that you don’t have a partition for your root, which should have been created by the installer. If the only partition on /dev/sda is your swap, then that would be strange.
When I was distro hopping, so many of my problems were resolved by “reinstall and do it again”. It’s like the “have you tried turning it off and on again?” of installing operating systems. Who’s to say what happened? Computers can be very weird sometimes.
