Windows 7: Windows 7 Installation CD - Can boot in Legacy mode but not in UEFI

Windows 7 Installation CD - Can boot in Legacy mode but not in UEFI

When i try and boot my Windows 7 x64 DVD in UEFI mode my computer completely skips it and boots my hard drive. However when I boot in legacy mode i can boot the CD but i get the error 'Windows cannot be installed to this disk. The selected disk is of the GPT partition style'. I'm assuming i get this error because i'm not booting via UEFI mode.

Where do you buy your Windows 7 DVD from?

Got it from Microsoft's Amazon Store. I checked if the DVD was working on my desktop PC and it worked fine. I'm assuming that there's something in the BIOS of my laptop that i'm missing.

I restored to default and i get the error:

'Windows cannot be installed to this disk. The selected disk is of the GPT partition style'

when selecting a partition. I've formatted it via Drive Options (Advanced) > Format and it still doesn't work.

Is this your setup?

If yes, click NEXT.

The popup is only a warning.

Yes, that's what I get. It wont allow me to click next.

Thank you for the quick replies.

The default settings on the BIOS look like this:

BOOT: Legacy Support
BOOT ORDER: UEFI FIRST

Your uEFI BIOS needs to be set to uEFI Support.
