Parallels told me I had to reactivate Parallels within 3 days since my hard drive has changed since it was installed. After reactivating Parallels, XP will not boot up. I get the following message: Windows could not start because the following file is missing or corrupt WINDOWS\SYSTEM32\CONFIG\SYSTEM You can attempt to repair this file by starting Windows Setup using the original CD Rom I would appreciate any help I can get to fix this issue. Thanks
