Windows check whether your system supports UEFI by following these steps:
- Press Win + R, type
msinfo32, and hit Enter. - In the System Information window, look for BIOS Mode.
- If it says UEFI, your laptop supports it! If it says Legacy, it does not.
For UEFI supported system, we can opt to GPT for partition scheme. Otherwise, choose MBR.
Alternative way to check
