windows 10 - Cloned a MBR partition on a new HDD with GPT, not showing up in Win10

I'm having a problem with a new HDD. My old HDD was making annoying noises so I replaced it with a new one. I cloned the old MBR partitioned disk with MiniTool Partition Wizard and set GPT as the new partition type.



I booted into Windows and the new drive didn't show up in Explorer. I opened disk management tool and found that the drive was listed there, unlabeled. All options in the context menu were greyed out and the drive displayed 100% free space.



I then opened Partition Wizard and the drive was displayed there properly, with proper driver letter, size, free space, label and partition type. I've checked my BIOS settings multiple times to ensure that I'm booting in UEFI mode and I even tried toggling some other switched like CMS without results.



Does anyone have any idea what might be going on? I couldn't find an identical situation anywhere on the internet. I know I could just convert it to MBR but I'd like to fix the problem now since I'm gonna face it sooner or later when I want to get a 3TB hard drive and have to use GPT partitioning.



All options greyed out




Looks good in MiniTool



EDIT:
Even in the Partition Wizard the disk management options are greyed out so I can't convert to MBR even if I wanted to.
