Windows 10: Drive changed to GPT and no operations can be performed.

Was trying to install Ubuntu, couldn't find one of my partitions on my HDD, so went to this forum: https://askubuntu.com/questions/343768/why-is-the-installer-not-showing-any-partitions. And the followed the method mentioned in this comment: https://askubuntu.com/a/443535The above post didn't help, so to check on the partition, I booted into Windows, and there it was, the Drive displays itself as GPT with a size of 2TB, even though the HDD was of 1TB. I cannot perform any operations on it, on a right-click, it would just grey out all options, the only accessible option was the "Help" one.

Cannot convert GPT to MBR.

Hi Michael,



I suggest you to follow the below steps and check if it helps.

This method you have to backup all your data and delete all partitions and volumes. Then use the
DISKPART command.

• Open command prompt and type in DISKPART and press Enter
• Then type in list disk (Note down the number of disk you want to convert to GPT)
• Then type in select disk number of disk
• Finally type in convert gpt.

Hope the information helps. Do reply if you need further assistance.

 

GPT does not mean a faster operating system.

Well, for the P9X79 Deluxe I have, unless you boot from the installer using the "UEFI" option in the boot list, it won't actually do this out of the box. If the installer starts with UEFI, it will install for UEFI but, older machines like mine will give you the option and will explicitly call it out and it's important to select UEFI if you want your boot drive to be GPT but, this only matters for the boot drive.

For everyone else, context helps. This thread came out of this one that was closed because necro'ing threads is usually frowned upon.

GPT drive

I just upgraded my computer from Windows 7 to Windows 10. I have software installed on an SSD and data on a 4TB second hard drive. Somehow, in the upgrade, my data drive turned in to a GPT Protective Partition. I would like to return it to a Primary Partition
without losing the terabytes of data on it. Any suggestions?
