Error loading operating system

So I have a dell inspiron 1720 laptop and I have gotten rid of vista. I have been using tiny xp and just recently decided to reformat after a virus bomb. I was going to particion my drive space so the OS would be in it's own part just in case it happened again I wouldn't have to lose some info. In the middle of the reformatting it lost power. When I try and start up the comp again it gives the error loading operating system message, and when I try to boot from the disk it gives the same message. So I can't continue formatting. I'm doing a diagnostics test right now to see what errors it gives. Is there anything anybody could think of to fix it? Any advice is much appreciated. Thanks.

 

Can you try removing the drive and formatting it on another computer?
