I attempted to install windows from a USB, but it gave an error saying "Error: Windows Cannot Be Installed to This Disk. The Selected Disk Has an MBR Partition Table. On EFI Systems, Windows Can Only Be Installed to GPT."

I disabled all EFI boot sources and safe boot, but the error is still appearing.

I would like to know how to convert my drive from a MBR to a GPT without having to delete the partitions already on the drive, without suffering any data loss, and without purchasing software (like that from AOMEI) to do so.

If you know how to solve this problem, your help would really really be appreciated! thank you!

Tip   Tip
Error message when you boot from the Windows installation media in Legacy BIOS Boot Mode:

Windows cannot be installed to this disk. The selected disk is of the GPT partition style. (see screenshot below)

That is because Windows can only be installed to MBR disk in Legacy BIOS Boot Mode, but you plan to install Windows on a GPT disk.

- Boot from the Windows installation media in UEFI Boot Mode, so you can use GPT (GUID Partition Table).
- But if you want to use MBR (Master Boot Record) partition table, then delete all partitions on the disk.
