CONVERTING GPT to MBR DURING INSTALLATION

During Windows 8 or any version of Windows Operating System installation, you may face problems by installing it. Possible problem that you will get to encounter when you are installing from DOS to Windows 8 is when choosing "Where do you want to install Windows?" and none of your partitions are able to install Windows in it because it may be that your partitions are all in MBR format. So here's the easy way to get it all done!

Take Note: I assume that you are already getting this message: "Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks."

So now, all you're going to do is:

Step 1: Press Shift + F10 (This will open Command Prompt)

Step 2: Type in "Diskpart" then press ENTER.

             It will be shown like this:

             X:\Sources>Diskpart

Step 3: Type in "List Disk" then press ENTER.

             DISKPART> List Disk

Now it will show you the list of the disks that you have.

Step 4: Select the disk that you want to convert from GPT to MBR. Id you want to convert Disk 0 then Type in "Select Disk 0". Just put the number of the disk you want to convert. Then press ENTER.

             DISKPART> Select Disk 0

Now after pressing ENTER, "Disk 0 is now the selected disk." is going to be shown.

Step 5: Now type in "Clean"

            DISKPART> Clean

After pressing ENTER, you will get this:

            Diskpart succeeded in cleaning the disk.

Step 6: Type in "Convert GPT"

             DISKPART> Convert GPT

and then ENTER! Now you're done converting your disk and is ready to get your Windows installed in it. You will get "Dispart successfully converted the selected disk to GPT format."

Now click exit and start the installation process again and everything will just work out!
