Windows 8 and newer versions support it.
If you plan to reinstall the OS, your USB stick must also be in UEFI (GPT) format.

Step 1: Enter BIOS / UEFI

Step 2: Switch Boot Mode
- Go to the Boot, Startup, or Boot Mode tab
- Set Boot Mode → UEFI Only or UEFI
- Set CSM → Disabled (if available)
- If you see UEFI/Legacy Boot, choose UEFI
Step 3: Disable Secure Boot
- Go to Security, Boot, Authentication, or Secure Boot section
- Find Secure Boot and set it to Disabled
If Secure Boot cannot be changed:

- Now Secure Boot should be editable
Step 4: Save and Exit
Press F10 → Select Save & Exit → Confirm Yes
