Converting MBR dual boot installation to GPT

[Svyatko]

@nrickert

Yes, they are. There is still an MBR (or PMBR – protective MBR) that allows the disk to be used as if it were using MBR/DOS partitioning. It boots fine with linux, but Windows probably won’t like it. I think there’s a way of using hybrid partitioning that can work with Windows.

“Yes” for Linux, “No” for Windows.

To OP: “backup + full reinstallation + restoring user’s data” is the best way IMHO.
