Resolved XP Registry file failure

I goofed. While clearing junk from the hard drive using a Tree Program I accidentally deleted NTLDR...whatever that is. The pop-ups read:

"NTLDR is missing..." "Registry file failure c0000218 "

It is still in the Waste Basket...and can be restored...I think

The above message appeared after I rebooted. I had to use F10.

I cannot find the restore disc. I HAVE THOUSANDS OF SAVED E-MAILS...so I do not want to loose them.

Is there a way to get the unit to boot...so I can restore the deleted program?

Thanks,

Thank you Evan!

Very comprehensive but I'm having a little trouble with it. I'll keep trying.

Thanks again. I'll mark it solved.
