This document pertains to HP and Compaq desktop PCs that came with Windows 7.The following error opens when attempting to start the PC:BOOTMGR is missingPress CTRL+ALT+DEL to restart the PCIf you recently installed an additional hard drive, turn off the computer and remove the drive before using the following steps:
Open HP System Recovery:CAUTION:Do not perform a system recovery! Stop at the first recovery screen.
Press the F11 key repeatedly while the computer is starting.
If you have a recovery disc, turn on the PC and insert the first recovery disc into the drive. Use the disc to enter the system recovery.
Select Microsoft Startup Repair tool and wait for repair to find and fix errors. When finished, restart the computer; even if the startup repair tool finds errors but cannot fix them.
If the error message persists, open the recovery manager screen as was done in step 1.
At the recovery manager screen, press ALT + D.
Enter the following text at the command prompt: bootrec /rebuildbcd
If bootrec displays "Add installation to boot list?", press y .After bootrec completes successfully, the computer displays "The operation completed successfully".
To close the command prompt, enter the following text: exit
At the Recovery Manager screen, select Microsoft Startup Repair tool (again) and wait for startup repair to find and fix errors. When finished, restart the computer.
The error should no longer open. If it does, perform a system recovery, making sure to backup important files.
If you removed a hard drive before using these steps, replace the drive. If the error occurs again, make sure the additional hard drive is not set as an active drive. Only the main bootable drive should be set as active.
It appears that the computer is infected with virus and may need full system recovery. You can restore the computer back to factory default,to do so, follow the below steps: Turn OFF the computer, now as soon as you hit the power button, keep on holding "Alt" key

support at 1 800 816 2237 and order for an Recovery Disk.
Why all these clueless suggestions? I came here looking for help, but it appears I'll be solving my own problem and lend a hand. First attach something bootable via USB like you already know. Change boot order and boot from some kind of XP install disk. That's where I'm at right now. I'm now in the recovery console which gives me a command line. I had JUST READ somewhere the comand line commands to restore the boot manager that we just compressed.
Hold on....OK ! Problem fixed.
Step by step:
1)Get external CD reader and plug into USB
2)Boot Mini hit F10 or F12, whatever it says to change boot order
3)Reboot and you'll see you now have option to change boot order on bootup.
4)Boot to some kind of XP start disk(stupid me never even looked at HP's recovery disk yet - I didn't want to go there!)
5)Let the startup program run til it stops asking you to select an option, and hit R for recovery console
6)You'll want option 1 for c:/windows and type your password when asked
6)type fixboot then enter
7)It will happily inform you that your boot record is repaired
There may be some warnings or statements in between. You're desperate - agree to whatever they say! ;-)
9)Don't worry, be happy
If you can't stand that you now have that message booting up every time and it looks weird, RIGHT click my computer, properties, advanced, startup and recovery settings, and edit ....change default operating system from ** to Microsoft Windows XPHome etc."
click edit and for good measure delete where it has WINDOWS="" as an operating system. Don't mess with this if you're not sure.
10)Now be happy!
#1 make sure there is no floppy diskette in A:
#2 make sure the hdd is seen in bios (Reseat drive connections)
#3 if those steps don't resolve, then run diags on the HDD see if it fails.
If diags pass, boot to recovery console, run CHKDSK /P
There might be a bios setting that you have too set for the recovery mode. If you can get into the BIOS then check to see if there's a setting for recovery. You can also try at boot up (before the Windows error) to hit Ctrl-F10.
