Bootmgr is missing

I have the same problem, but not with xp with windows 7 home premium AO acer group.

Run a Chkdsk:
Take the Windows XP disk. Boot from it, then DO NOT select F2 (automated system recovery) but continue through the procedure until you get to the point where you can choose between installing Windows XP and entering the Recovery Console. Once you get into the Recovery Console, do chkdsk and fix potential errors on your disks! Chkdsk C: /R


OR:


Perform an XP repair:
When you boot with the Win XP install CD-ROM, it loads a minimal operating system, similar to DOS, but compatible with Win XP. At the first screen you select install Win XP (not Recovery Console) and at the next screen it will find that you already have Win XP and offer to attempt a repair. This repair should not touch your Applications or data; it just reinstalls the Windows files. This is great because when it works you don't need to reinstall all your software.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
