Please run “os-prober” - does it find Windows now, when you are booted with legacy BIOS?
Hi,
Sorry but I got your message too late. I ended up just booting with the Windows OS CD and running the bootrec /fixboot command and then once WIndows was working normally I just reinstalled Linux (paying careful attention this time not to choose UEFI).
Thanks and Happy Holidays =)
Problem resolved.
