Mbr to gpt

Hi

Was your system working correctly previously?

Have you made any changes to bios or uefi settings recently to cause this problem?

Your link to microsoft gives me a page missing error so i have no idea what it says

Gpt partitioning requires correct uefi setting for disk access a 64 bit windows Vista sp x or latter and is only required if boot drive exceeds 2 TB

Regards

To manually wipe a drive and convert it to GPT:
Turn off the PC, and put in the Windows installation DVD or USB key.
Boot the PC to the DVD or USB key in UEFI mode. For more info, see Boot to UEFI Mode or Legacy BIOS mode.
From inside Windows Setup, press Shift+F10 to open a command prompt window.
Open the diskpart tool:

Copy
diskpart
Identify the drive to reformat:

Copy
list disk
Select the drive, and reformat it:

Copy
select disk <disk number>
clean
convert gpt
exit
Close the command prompt window.
Continue the Windows Setup installation.
When choosing an installation type, select Custom. The drive will appear as a single area of unallocated space.
Select the unallocated space and click Next. Windows begins the installation.
