GPT/BIOS Install on Virtualbox

25 June 2020, 09:08:15

I followed the installation guide and made the following partitions

/dev/sda1, 8mb, bios boot
/dev/sda2, 260mb, efi system
/dev/sda3, 1gb, linux swap
/dev/sda4, 23gb, ext4

i formatted both sda1 & sda2 to ext2.

What command should I run to install Grub? I couldn't quite figure that out from the Arch Wiki.

I tried `grub-install --recheck /dev/sda`. That completed without errors, but grub did not run properly after reboot.

You will either be using UEFI or BIOS, not both.
In case you use BIOS just follow the instructions for BIOS systems.
In case you use UEFI:
- make sure your virtualbox supports this
- format the EFI partition using mkfs.fat -F 32
- then follow the instructions for UEFI systems
