[arch-general] Single Drive Fresh Install (mbr/grub2) Fails to boot (can boot existing from .iso??)

[Rijul Gulati]

I cannot say exactly what's causing this issue.

I'd suggest after enabling UEFI from BIOS, try re-installing grub2 and
regenerating grub2.cfg maybe?

If this did not work, try re-creating partitions (that is set ESP on
/dev/sda1 and set boot-flag ON on 1) . Also there is no need for BIOS boot
partition since ESP is already provided. Then install grub and boot?

Also, I see "customised boot" option for UEFI.

Tried this? (If it's applicable for your system)
