I’ve installed Manjaro Linux on a flash drive using BIOS+GPT. Is there a way to make it support both Legacy and UEFI boot?
(sorry for my poor English)
change it in your bios settings
The option isn’t available in UEFI mode. I can only boot it in BIOS mode.
I haven’t done it myself, but it should be possible.
If you’re dual booting with windows, then you may have to reinstall windows for it to work in uefi.
