EFI motherboard - can't install Win10

Tried to do a clean install, Windows said it could not reformat the disk because it has a MBR partition table and on EFI systems, Windows can only be installed on GPT disks.  took the disk to a shop to format. Tried to install to the clean disk, got the same message.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Formatting isn't enough. You catually have to remove the partitions and flip it to GPT.

Yup, GPT on all partitions and UEFI BIOS and then try again.

Taken from here:

From inside Windows Setup, press Shift+F10 to open a command prompt window.

Open the diskpart tool:

Identify the drive to reformat:

list disk
Select the drive, and reformat it:

select disk <disk number>
convert gpt

Then you should be able to install to the disk.

Hope this helps!

Although I understood what the others meant, Christopher went into a short step by step explanation and showed me where to get a more detailed explanation/instruction.  Not always possible but best way when it is.
