I restored my boot.ini file by opening windows pss folder and copying boot.ini to drive C. I renamed file and rebooted and everything went well except the boot.ini file disappeared. I retraced my steps and tried again. I rebooted with no problems except the boot.ini file disappears, vanishes. Temporarily I redo this proceedure each time I use my computer. I am using xp media center with service pack 3. Please advise.
