When you want to install W10 or W11 on your PC and get the error message like
"you have a MBR disk but a GPT disk is needed".
There is a really easy solution!
Click cancel, and then while still having the Install window open, use shift-F10 to open a command window.
Enter the command line as follows:
• Diskpart (is an app that lets you manage the disks and partitions)
• list disk (it shows Disk 0 which is your harddrive, Disk 1 which is your usb drive)
• select Disk 0 ( > "now Disk 0 is selected")
• clean
• convert gpt ( > "successfully converted the selected disk to GPT format")
• exit
Once the command prompt is closed, you can continue with the Windows installation.
