He purchased a refurbished hard drive due to budget constraints and allocated much of it to RGB lighting. During Windows installation, the system reports an error stating that Windows cannot be installed on this disk because it has an MBR partition table, and EFI Windows only supports GPT disks. Someone knows how to resolve this issue for a WD Scorpio Blue 250 GB drive.

Ensure the partition is removed from the drive prior to installation; it will format to GPT. The BIOS indicates EUFI support and legacy boot, and the system is configured for GPT only.

Yes, you can format it on another PC or using GParted Live.

Yes, there might be a way to handle it on the same device without using another PC.

You can install a small Linux live system using CMD on the installation disk or create a bootable CD/USB. See this guide: https://gparted.org/livecd.php for details on using GParted with the best partition manager.

To change from MBR to GPT during Windows setup, launch Command Prompt via Shift + F10 on the install screen. Begin by entering "diskpart" to launch the tool. Proceed with "list volume" to check for partitions on the MBR disk you wish to convert. If any exist, remove them using diskpart delete partition first. Next, run "list disk" and press Enter to view all disks. Record the disk number you want to convert. For example, use disk 1 as an example. Then type "select disk 1" and press Enter to select it. Proceed with "clean" and hit Enter to erase all partitions on that disk. Finally, type "convert gpt" and press Enter to start the conversion. You should see the Command Prompt confirm the successful GPT format change.

However, you'll need a different machine to download it since he only has that one PC.

Should press Shift + F10 at that screen. If that doesn't do anything, make him check his keyboard to make sure the F rows is enabled and doesn't need fn to be pressed or some other crap like that.
