Windows 7 won't boot up after I renamed catroot folders

[sunkissed64]

Well after trying to fix the fact that windows update will not update (i renamed the catroot folders as
someone had suggested) windows 7 won't boot up. The auto feature that's supposed to do the job
(repair windows so that my computer/windows boots again) was unable to. I can't even do the usual
safe mode F8 root. HELP. I don't have a windows 7 disk because though my computer came with it
loaded I didn't get one. Please guys I need help. How can I get to the repair recovery I know must be on
my computer. I was thinking maybe a restore is the easiest way to go but if I can't get to it...UGH
