After having installed Ubuntu Server 20.04.2 LTS, when starting my laptop it throws an error stating "No bootable device". When I enter the boot options menu by spamming F12 on startup, I find the "EFI device: Ubuntu" which makes the OS boot. However, when I open the BIOS by spamming F2, in the boot order menu, I can't find it. Any idea how I can make it the default boot drive anyway?

Laptop: Acer Aspire V3-571G

Operating System: Ubuntu Server 20.04.2 LTS

Your laptop could be set to boot legacy instead of UEFI. In the boot options, see if you set it to only boot UEFI instead of Legacy (BIOS) or [CSM].(What is CSM option)
