There was an interesting article in the Langa newsletter today regarding a
Nondestructive, No-Reformat Repair/Rebuild Option For Windows XP
I’ve put together a recap of the steps outlined in that article

Fred Langa’s newsletter is well worth a read and subscription, free or paid option (that includes more articles). I have had the paid for version for two years now and well worth the modest $12 subs.
Additional Options
A version of Bootcfg can also be run from inside Windows. Type “Bootcfg /?” (minus the quotes) in the Start/Run line to see the commands available that way. Note that the /Rebuild command isn’t available from inside Windows; you can only run that from within the Recovery Console. (That makes sense because you only need to totally rebuild the boot information when Windows won’t start normally.)
