    I have serious troubble and need som expert help... I am going to install W8 enterprice 64 bit on my dell Latitude E6220 laptop and my HP Pavilion.

    First: the iso I have downloaded and burned to dvd is the iso from The Official Windows 8 Repository. And I have a legitime key to use.

    But, when i boot up my new w8 enterprice 64 bit dvd i come to the install screen. When i put the marker over my partision 1 (whitch is my windows partition) At this time im ready to format the partition. I get the following message:

    Windows cannot be installed to this disk. The selected disk has an MBR partision table. On EFI system windows can only be installed to GPT disks.

    This happens both on my dell laptop and also on my hp desktop. Same issu.

    I cant understand.. I have done this MANY times before on window 7. Whats happening on W8??

    Either boot as normal style, not EFI boot. Or wipe the hdd completely.

    While in Custom installation, go to Drive Options and delete that existing Partitions completely, after that chose New and define the size you like to have for the system or just click OK to use the full HDD.

    You will get min. 2 new Partitions, 1 with 350MB (for System Reserved) and the C (system) Partition. Now the installation should just go ahead.

    I think your motherboard has MBR BIOS and your disk is initialised as MBR and not as GPT/EFI BIOS. GPT is not required for <2.2TB disks. Assume that you want to install windows 7 on mbr instead of gpt

    Boot from DVD, but when you see the BIOS
    check the boot devices.
    There may be a UEFI DVD (which may be what the windows 8 is booting from)
    There may also be a DVD (with manufacturer's name). Make that the first boot device, save and reboot.
    Your problem may be solved now.

    There is also a solution to convert the boot disk from GPT to MBR:
    Insert your Windows 7/8 installation media and boot.
    AT BIOS, you will see boot order as whatever, but you will see UEFI dvd, but also will see your DVD writer (say HP 1260i) without any UEFI prefix. Select that boot device (without UEFI prefix)
    After booting you see the Install Windows 7 screen, press Shift + F10 to open a command prompt.
    At the command prompt, type Diskpart, press Enter.
    Type List Disk, press Enter.
    Type Select Disk # (where # is the number your drive shows up as), press Enter.
    Type Clean, press Enter.
    Type Convert MBR, press Enter.
    Type Exit, press Enter.
    Close the Command Prompt window.
    Click the "Next" button.
    Click the "Install now" button.
    Accept the terms and click the "Next" button.
    Choose "Custom: Install Windows only (advanced)."

    For MBR to GPT, you type convert GPT.
    Now to install windows 7 now without system reserved partition (see this tutorial)

    SOLVED:)

    "While in Custom installation, go to Drive Options and delete that existing Partitions completely, after that chose New and define the size you like to have for the system or just click OK to use the full HDD."

    This diddnt fix the problem.

    I went into bios and removed the option for UEFI DVD boot. After this I was able to install as normal.

    thanks for good help:hug2:
