Cannot boot into Windows XP. PLEASE HELP

[spin_er]

For some reason when I restarted my computer recently.
When it went to boot up the following message appeared.

"Windows could not start because the folling file is
missing or corrupt: \windows\system32\config\system"

Does anyone have any clue how I can fix this?

If I reinstall XP will it delete my C: drive do it?

Any help would be GREATLY APPRECIATED

Thanks all
