So, here's the problem. Friend asked me to sort out laptop. Tried recovery console and FIXBOOT & FIXMBR, no joy. I was going to do Repair installation but Windows says 'P].artition1 [Unknown'].
So he needs a fresh install. Problem is that I can't get to the HDD to rescue the files onto a USB flash drive or anything because the drive isn't reading as NTFS anymore (I suspect this is my fault with FIXMBR).
I do believe that all of the data is stil there though; if it tries to boot from HDD, it gets as far as the F8 boot options screen.
