To resolve this issue, start the computer from the Windows XP CD, start the Recovery Console, and then use the Bootcfg.exe tool to rebuild the Boot.ini file.
Microsoft's Knowledge Base has a complete step-by-step walk though for you here:

During boot I get a message telling me that my boot.ini file is missing or corrupt. It still boots but I would feel happier if this problem could be fixed. Any help would be appreciated. Thanks.
