    linux-windows mbr/gpt error on every reformat


    hi. im one of those guys that heard about linux and decided to give it a try, i decided i don't like it whatsoever, and after buying windows 8.1 (because i erased my recovery partition) every time i reformat my windows 8.1 i get a gpt/mbr this file can't be installed here error although simply removing the partitions allows re install. what is this, and is there a way to fix my hd. i have no intention of ever installing linux again. help would be much appreciated.

    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.

    so if i boot in uefi mode, windows will automatically install in gpt mode? that's what seems to happen i notice. what is the cause of this mbr gpt partiton error message. also, i read there is a way to fix this in the windows command line https://technet.microsoft.com/en-us/.../dn336946.aspx

    does doing this through command line do the same thing that booting in uefi does. or is there a different result when its done manually?

    does this mbr/gpt do any damage to the hard drive?

    it was only after i installed linux that i first received this message on a reformat. will using the command line fix the hd like new, or does installing linux on a 'eufi asus' for example, permanently damage the hd?

    if you press shift + f10 when you are installing and go to diskpart, clean, convert gpt (like in your link) then you'll delete your mbr partition table (if that is what you have) and create a gpt one.

    You want a gpt structure to install uefi (that is why you are getting the message). It doesn't damage the disk in the slightest - the partition table is just another file.

    You should bear in mind though that when you clean the disk everything (all partitions) on it will become unavailable.

    would it be too much to ask if you can type the commands i need to type because microsofts tutorials can be a bit hard to understand.

    ms says this,

    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:



      diskpart




    • Identify the drive to reformat:



      list disk




    • Select the drive, and reformat it:



      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.

      but from doing ms tutorials, they always seems to missing something.

      could you please clarify what i need to read and then type? would be very thankful.

    when you say, 'unavailable' does that mean that i will no longer get the can't be installed to this partition, and is their any kind of benefit however small in doing so even if its just removes an annoyance of some kind?

    I wouldn't bother changing it until you clean install again, if at all.

    During install when you get to the Where do you want to install Windows screen shown above in @genet 's post press Shift + F10 and enter the following commands in bold (pressing enter after each one) in the command prompt window that appears.

    diskpart
    list disk
    select disk x - where x is the number of your disk shown above, probably 0 (zero)
    clean
    convert gpt
    exit
    quit

    Your screen output will look something like this:

    Code:
    X:\>diskpart
    
    Microsoft DiskPart version 10.0.10041
    
    Copyright (C) 1999-2013 Microsoft Corporation.
    On computer: WINDOWS10
    
    DISKPART> list disk
    
      Disk ###  Status         Size     Free     Dyn  Gpt
      --------  -------------  -------  -------  ---  ---
      Disk 0    Online          113 GB      0 B
    
    DISKPART> select disk 0
    
    Disk 0 is now the selected disk.
    
    DISKPART> clean
    
    DiskPart succeeded in cleaning the disk.
    
    DISKPART> convert gpt
    
    DiskPart successfully converted the selected disk to GPT format
    
    DISKPART> exit
    
    Leaving DiskPart...
    
    X:\>quit
    The quit command will close the command prompt window and you can carry on with your install as normal. Then the next time you clean install it should not complain as the disk will be gpt

    When I said clean makes all the partitions on your disk unavailable I should probably have said it deletes all your partitions. You should only do this on a disk with nothing on it you want.

    Whether you think it is worth doing depends on how often you clean install and how much it bugs you. I can't think of any practical benefit to doing it but probably I would assuming if I didn't care about anything that was on the disk.
