So here's the problem:
My friend wanted to put Windows 10 Pro on his laptop. We installed MiniTool Partition Wizard program on his laptop. Entered the program, chose partition C: - wipe disk, since there's OS on C: it won't do it from Windows, we restarted the laptop and program did his thing. Then we put USB with Windows 10 Pro on it, booted from USB, Win 10 installation window appeared. Then clicked all stuff you normally do when installing brand new OS. And then when part with on which disk/partition you want to install Windows came, there was a problem.
Error message was:
"Windows cannot be installed to this disk. the selected disk has an MBR partition table. On EFI system, Windows can only be installed to GPT disks"
Then we followed these instructions: https://technet.microsoft.com/en-us/library/dn336946.aspx
But the problem was, when we deleted partition (146.5GB) which is partition C: we couldn't proceed with installation.
Everything would be fine if partition D: (785GB) wasn't full of videos, pictures, backups etc... we would delete all partition and installed it there. But we can't do that.
So now I'm asking you experts what to do? Is there any solution? Can we somehow get to partition D: since there's no OS on laptop now? Maybe to connect laptop on my PC via USB cable and then transfer stuff from D: partition. Will my PC recognize laptop like removable USB disk?
Please help if you can!
