Re: Unclean reinstall?
Are you saying this because the Windows partitions appear to be intact? Or, are you saying this because, as suggested, you actually booted into Windows and confirmed it still boots and runs OK?
EDIT: Windows is unaffected; I was afraid I had overwritten Windows by mistake too at first, but thankfully no.
If it's the former, then you really need to do the latter -- as resizing Windows filesystems with GParted sometimes leads to filesystem corruption -- something you would only detect if you actually tried to use Windows after the resizing.
Ubuntu 16.04 Mate, Mint 18 Mate; MS Win 8.1, MS Win10 Pro.
Will not respond to PM requests for support -- use the forums.
