Update My windows 10 to Windows 11

Hello,

Yesterday i try update my windows 10 to winsows 11 but when i try follow information on windows support that i need go to Advance Resertart and go to UEFI option i dont see this option. I look up what can be reason, and apparently that cause i have Legacy version instead UEFI. I try change this in my bios. When i try do that after chang it in option and save computer resrtart and back to Bios menu. After i revert this to legacy computer turn on normally.

Tahnk you for any advice.
