"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.
Lol yeah copy/pasted wrong line, should have proof read. Wait what? is "fixboot" not for fat as well? i must have fat on the brain tonight that's all i can think of now fat fat fat.
No the two commands "Fixboot" and "Fixmbr" at the recovery console will see the boot information rewritten and new mbr entries created for XP. The fdisk /fixmbr command can only be used when booting up from an MS Dos boot floppy.
"To fix the boot sector, start the computer with a MS-DOS system disk and run the following command:
fdisk /mbr" That's an extract from the MS page on boot viruses where you use the old dos command at this late. How to Protect Boot Sector from Viruses in Windows

You can also do what Captain Zero said, but additionally set the time to choose to 0 seconds.
Ok now that i have had some sleep the fat is gone . You can't do what captain zero said because that edits the boot.ini and the Windows 7 entry is not in there it is in the BCD. So the OP would need either to do what you suggested with the correct commands of course or use bcdedit or if you prefer a gui then Easybcd.
