I tried to recover my original windows that's loaded on the (14GB) hidden recovery drive, but it seems those file are damaged, so I created a bootable flash memory and decided to have a fresh installation, but I ran to two problems regarding backing up my user profile.
1-my laptop cannot find my external HD - I tried the HD on my other laptop and it's working fine- is that because I have two USB connections ?
2-Since my laptop couldn't find my external HD, I tried to copy my user profile to the recovery hard drive. However, I got a permission error, but it did copy some trivial files only
just now I used the Windows 7 installation CD that I had burned earlier, but it's not helping at all, it doesn't let me get to the recovery screen, the cd could be damaged too I don't really know

.. maybe I need to burn another copy ?
Please help, what I can do ?
