Are you doing this as a dual-boot scenario? Cus, if I follow this correctly... you had XP, added Windows 7 but, lost BOOTMGR... Now you have 7 & want to put XP back. Would be spell it out for me before I attempt offering you any (maybe helpful) comments. Thanks.
I have been through installs of 7 for multi-boot set up & had the BOOTMGR disappear & had to fix it/get it back. Still I need a better, clearer understanding of your scenario before I offer anything more.
OK, I had XP, Installed W7, all is still good. I have not lost the boot manager. However I want to reinstall clean XP and I know it will grab the boot manager, so I was looking for an easy way to reinstall XP that reinstate the bootmanager to its current state (dual boot)
If you use startup repair in Vista or Win7 you do get an option to select cmd prompt for using bootxect.exe etc but the recovery disc is a more automated process using a pre created or downloaded ISO to make a CD
