help please computer wont start

hi all, i have a dell vostro 1000 running vista business.
i was doing a system restore and it was taking a while i thought it had froze so being impatient i held the power button and shut it down, now when i turn it on and i sign in with password, it gets to the screen with the loading bar at the bottom and stays there.
iv tried options after pressing f8, repair my computer, last known good configuration and even safe mode but it keeps getting stuck on the same screen.
im guessing switching it off has upset something.
i dont own any backup or vista discs.
can anyone help please?

john

Welcome John
A restoration is not always done with F8
How do you access Dell’s recovery partition?
Read the above, try the various keys by booting the computer and then during boot rapidly and contiually hit the appropriate key.

thanks rich,
i had a look through the site but couldnt find anything related to my model. would be good to restore it to factory condition tho.
anyway, iv got it fixed now managed to get a vista boot disc and repair it. it was running a bit slow at first but seems to be running fine now.
thanks for the reply tho much appreciated
