"fdisk /mbr"? Fdisk is the old dos partitioning tool for Fat based versions(9x-ME).
To see the XP installation return to it's original configuration you would boot upto the recovery console by using the "press R for repair" option while booting from the XP disk to reach that.
Once you are logged on as administrator when selecting the XP installation detected you simply use the "fixboot" and "fixmbr" commands and restart the system for a normail XP startup.
You won't be able to remove the boot folder the 7 installer placed there unless you can take ownership as well as gain the permissions needed to uncheck the read only box in the properties. But you will no longer be booting from the bootmgr but XP's ntldr file and boot.ini configuration.
