    Windows 8.1 install error.


    Well today i woke up an turned on my PC i waited but the only thing that came up was a black screen i did some research and i found out it was BSOD i tried almost everything to fix it then i thought about what if i just format my pc and reinstall windows with the disk so i put the disk it and booted it up i choose advanced install and for some reason it didn't let me install it so then i was like oh maybe it is because i have it installed already so i formatted my HDD and C: drive i knew the C: drive is i formatted that my system wouldn't run right so i though maybe if i install windows 8.1 in again it would work but it didn't so then i tried even more to install it to get my PC back to normal but when i tried to install it to the C: drive it says "Windows cannot be installed to this disk. The selected disk has MBR partition table.On EFI systems, Windows can only be installed to GPT disk." and " Windows cannot be installed to this hard disk space. The partition was reserved by the computer's Original Equipment Manufacturer (OEM)". Please HELP T-T

    Tip   Tip
    Error message when you boot from the Windows installation media in Legacy BIOS Boot Mode:

    Windows cannot be installed to this disk. The selected disk is of the GPT partition style. (see screenshot below)

    That is because Windows can only be installed to MBR disk in Legacy BIOS Boot Mode, but you plan to install Windows on a GPT disk.

    - Boot from the Windows installation media in UEFI Boot Mode, so you can use GPT (GUID Partition Table).
    - But if you want to use MBR (Master Boot Record) partition table, then delete all partitions on the disk.

    Delete all the partitions on Drive 1, if you want to install to Drive 1.
