What did you delete? Did you by any chance delete anything out of the /Library or /System folder off the root level of the drive? Probably the best option is startup the computer and then immediately hit Command + V. This will boot into Verbos mode. When does the boot process stop? What does it say? This will help tell us where it is failing in the boot process.
