I have been following your guide but have quickly hit a problem.
Firstly the system recovery tool startup screen advises me that Windows 7 is installed on D: (I thought it was C

. Anyway, in CMD I can access C: but it contains just two folders called files & recovery and a file called install.wim. No sign of the windows folder.
I cannot access D: as it says "data redundancy error (cyclic redundancy check)". After some quick googling I have tried running chkdsk on this drive but it tells me that it is RAW and chkdsk cannot performed on RAW drives. So this is where I have got.
I am not adverse to completely formatting with a new install but there are some files I would like to copy over first. So any help on how I could access files to copy to an external hdd would be welcomed too.
