HI Please help me here.

 

I have a DELL VOSTRO

I was busy downloading when my windows update to my system came up.

I accepted it, when it was completed and restarted my system. I logged on and struggled to go back on line.

I then restarted again.

I then got this error

 

"Internal Hard Drive Disk not found. To resolve this
issue, try to reseat the drive"

 

"No bootable devices--strike F1 to retry boot, F2 for
setup Utility, Press F5 to run onboard diagnostics."

 

I press F5 and run it once it's done it says  "Pre-boot System Assessment complete. No Diagnotic Utility Partition identified.

Pleass select OK to reboot your system".

 

I was only able to logon once my system was so slow I had to restart to have the same thing happen again, Now I can't even logon.

 

Any assistant would be extremelly appreciated.
