I'm very new to Ubuntu (12.10), so I apologise if I'm not clear at any point!

I had a Windows 8 (upgraded to Windows 8.1) and was fed up with it, so I converted to Ubuntu 12.10. I'd hoped to Dual Boot to at least get the benefit of both worlds.

I created a partition for it in Windows and installed from a LiveUSB key (and installed into that parition). So now Ubuntu works great, but Windows 8.1 no longer shows up on the start up screen (where you theoretically pick which OS you want to boot in).

I was going to try "Boot Repair" as mentioned here and restore MBR, but I don't want to start messing around with stuff I'm not entirely clear with.

EDIT:

For any of those who stumble here with the same problem, I just read here that a user wiped out his Windows partition by accident...

I checked my own computer with sudo fdisk -l and there's only one Device Boot (dev/sda1). I'm not an expert, but I'm guessing that means Windows has been written over.
