How do I convert legacy to uefi?

[jacatone]

Even though I set the bios mode to uefi before installing it keeps defaulting to legacy mode so I have to press f2 and manually reset to uefi. There seems to be plenty of apps in Windows to convert but haven't found any linux versions. Is there a way to convert in place so I don't have reinstall again? Thanks.

This seems more an issue with your bios, not the hard drive.
What computer, make and model?
What is F2 used for, in your case?

What you are saying, if I understand it correctly:

1. your computer powers on/boots up.
2. no idea what happens next
3. You need to hit f2, in order to enter your BIOS settings, and change its boot mode from Legacy to EFI/UEFI
4. then you can boot into Kubuntu?
5. On the next boot, you need to do this again

If this is the case, then it is NOT your drive needing to be converted, as it already is formatted correctly (GPT)
Is this happening after a normal reboot, or after a shutdown?
I wonder if the CMOS battery is dead, maybe? it is the main way BIOS settings revert back to a stock setting on their own.

Good idea.
If it does sometimes boot from UEFI setting, then the Kubuntu OS was installed in UEFI mode.
Settings in BIOS not sticking => what you said, Claydoh (assuming 'Save changes & exit' was selected in BIOS)

Do you have CSM support option? If yes, disable it.
"CSM BIOS is something that allows you to boot in legacy BIOS mode on a UEFI system"

Agree, absolutely. Ever since I read Qqmike's dissertations on UEFI, I've always enabled UEFI, disabled CSM, and killed the Windows-defaulted settings in the BIOS settings (Safe mode, RAID, etc.). Saved the settings and went on to installing Kubuntu. GPT and UEFI, 100%.
