    I can't install W10. It says my disk is not valid.


    Hi,

    I never saw something like this. It says that there is someproblem with my disk, in all of the partitions.

    I can't remember the exact message, but it was something with an acronym such as GTMP problem.

    This laptop is one year old, runs 8.1 and have installed lots of times Windows or Linux in it.

    The iso copy is fine, the problem has to be another.

    Thanks.

    Quote from this post: UEFI Boot Mode (installing using the GPT partition style) and Legacy BIOS Boot Mode (installing using the MBR partition style). -> link

    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.
