  3. Installing and booting windows 10 on a GPT partition

    I don't want to dual boot or anything fancy. I have a large disk ( 4 TB). I do not want to split it up into smaller MBR partitions. I want the whole disk to be a GPT partition. when I try to install windows 10/64 bit the install reaches the point where it
    is showing you the two partitions and it says windows cannot install because the partition is GPT. Perhaps I fooled myself in reading various links on the net that implied that you could indeed do what I wanted. If windows 10 will in fact install and boot
    up on a large single GPT partition please give some steps to accomplish this.

    Thanks

    Terry

    GPT SSD Disk - Manage EFI multi-boot for partitions Windows 10 and 8.1

    Based on your Disk management. I suggest that you re-label your C: drive and H: drive if H: drive is Windows 8 so we'll know which partition is 10 and which is 8.

    The first partition is System Reserved which was carried over when you convert from MBR to GPT and is not used.
    The next to last partition which you created is also not needed. Delete both partitions.

    Boot up Windows 10, open Admin command prompt and type:
    bcdboot H:\Windows =====> I assume H: is your Windows 8.

    The above command will create a dual boot menu for Windows 10 and 8.

    I also notice that you have Linux installed on disk 2. I suggest to leave it alone and boot it separately.
