Unsupported Firmware

The system disk must use GPT and the BIOS must use UEFI mode.

⦁ Check whether the Windows system disk uses GPT or MBR.

⦁ If it uses MBR, convert it to GPT with the Windows mbr2gpt tool or another trusted disk-management utility.

⦁ Change the firmware boot mode from Legacy/CSM to UEFI.

⦁ Restart the PC and confirm that Windows starts correctly.

⦁ Launch the loader again.

Warning

Converting the system disk or changing the boot mode can make Windows unbootable if performed incorrectly. Back up important data and verify that the hardware supports UEFI before continuing.
