Windows 10: Boot loop after partitioning 4TB Drive

    Boot loop after partitioning 4TB Drive

    I am really really frustrated and could use any help anyone can give.

    My computer is a Dell XPS8300 with the last BIOS they put out for this system...

    I have a Seagate 4TB (ST4000DM000) drive that is setup GPT and had 2 partitions on it (D:, E:) and worked fine in Windows 7.

    1. The windows 10 upgrade check said all was good
    2. After the windows 10 upgrade, I could only get to the first partition on this drive (D:)
    3. I thought maybe there was corruption on the 2nd partition on drive. caused by the upgrade
    4. Since I had a backup, I decided to repartition the whole drive again
    5. This caused a boot loop (login screen never came up, and repair tools could not fix)
    6. The only way to solve was to either physically remove the drive or to remove the partitions from the drive
    7. Right now I am stuck with the drive in my system, unpartitioned to be able to use

    What am I missing here? How do I get to use this drive?

    Have you tried to format using MBR?

    If you format MBR you only get 2TB of the 4 TB. You have to format GPT in order to be able to utilize the entire space on disks above 2TB from my understanding...

    Is that true if you partition it into two 2GB parts?

    Yes. If you use MBR you will only be able to create a single 2 TB partition on a 4 TB drive.
