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.

    When you change the setting in your BIOS from Legacy to UEFI and save, the computer restarts. However, it cannot find a valid operating system to boot from because your current Windows 10 was installed in Legacy/MBR mode. The UEFI system expects a drive formatted in GPT partition style. Since your drive is MBR, the UEFI BIOS has nothing to boot from, so it either loops back to the BIOS settings or shows a black screen with a boot error.
