I have a HP Pavilion computer I bought new in 2008, it has two 250 GB hard drives with C: split to include HPs Factory Image to restore it to new.
I had it set to automatically backup Drive C: to Drive D: which it did. Drive C: recent;y crashed, corrupted Registry it said, and all my attempts to recover it failed. So I finally used the Factory restore option with included a full backup, took 14 hours to complete. When it was done it advised me to restart and after restarting to restore the backup I had just made. I restarted but then, of course, it has maintained ever since that it is unable to find the backup to restore it.
Any advice on how to find it? I have loads of stuff there I really don't want to lose, that's why I backed it up all along.
