You start with your windows cd or some other op
As the machine boots up - it should have an option to hit F2 or F12
Hit the F12 key
This will give you the option of where to boot your machine from.
Select boot from CD/DVD drive
For me windows loaded some files and gave me an option to either install windows or repair.
I selected repair
I was then asked for the admin password -- typed it in.
It brings you to a command prompt :
Type in CHKDSK
Type in CHKDSK/R
Hit the ENTER key
Once your machine has finished and repairing the hard drive, type EXIT and press ENTER to restart your laptop.
PRESTO THE STUPID DELL LAPTOP IS NOW BOOTING UP AND IS NOW HAVING ALL ITS DATA BACKED UP.
I have also found another command that could be tried if the above fails. Bear in mind, i didnt have to do it, but will post it here anyway.
After the command prompt - type in FIXBOOT
