[FIX] Windows Cannot be Installed to this disk. The selected disk has an MBR partition

Yesterday While trying to Install a fresh copy of Microsoft Windows 8 on my Desktop PC via USB Flash drive I ended up facing a very frustrating and strange error specifying “Windows cannot be installed to this disk. the selected disk has an MBR partition table. On EFI system, Windows can only be installed to GPT disks.” which surprised me a lot since this was the first time i have ever faced such kind of error while installing a new windows on my system. Therefore just because of this error “Windows cannot be installed to this disk. the selected disk has an MBR partition table. On EFI system, Windows can only be installed to GPT disks.” I had to abort the whole installation process and had to lookup for possible solutions to fix this error and finally after a long search for few hours I finally end up finding a working fix for this error which I am going to share with all such users facing the same error while installing Windows. At most of the places on different forums, sites you will find only one solution that says for deleting all of your partitions and start fresh with installing Windows on these new partitions but honestly speaking this is not the way to get rid of this error because you will end up loosing all your important data and therefore this step is to be performed in the worst case scenario where every solution fails.

Note – This error is universal so can arise while installing any of the Windows Versions i.e Windows 8, Windows or Server 2008, 2008R2 etc therefore the below mentioned fixes are supposed to be work for all versions of Windows. In Windows 7 installation you might see a different error like “Windows cannot be installed on this disk. The selected disk is of the GPT partition style.” but don’t worry the solution is same.

Reasons for Such Error :

Such error arises mostly because of your hard disk partition configuration where your hard disk is having previously installed Windows partition or Current Windows Installation formatted with MBR and BIOS of your system is set to EFI/UEFI or your boot media DVD/USB is set to boot EFI/UEFI mode.
