Infinite Chkdsk Loop

After installing Internet Explorer 7 successfully, I began experiencing a warning nag that my c:\$Secure file is currupt and to run Chkdsk. Tiring of the nag, I opened the command prompt and ran chkdsk. I was then propted to run chkdsk /F after chkdsk completed its scan. When the computer rebooted, I became trapped inside this unending loop of chkdsk and reboots. The computer does not respond to my USB input to skip the utility operation and load Windows XP. What are my options at this point?

Best Regards,

Andrew Tozzolino.

P.S. I have since learned that there is an issue with installing IE7 with Norton AV enabled that precipitates this anomaly.
