Tips for a great answer:
There are a number of possible causes for BOOTMGR errors, including the most common "BOOTMGR is missing" error message.
The most common reasons for BOOTMGR errors include corrupt and misconfigured files, hard drive and operating system upgrade issues, corrupt hard drive sectors an outdated BIOS and damaged or loose IDE cables
Anothe reason you might see BOOTMGR errors is if your PC is trying to boott from a hard drive or flash drive that is not properly configured to be booted from. In other words, it's trying to boot from a non-bootable source.
This also would apply to media on an optical drive or floppy drive that you're trying to boot from.
make sure there are no disks in cd floppy usb drives
How to Create a Windows 7 System Repair Disc:
"This will show you how to create a Windows 7 system repair disc to use to boot to the system recovery options if you don't have a Windows installation disc, can't find your
Windows installation disc, or can't access the recovery options provided by your computer manufacturer."
If you do not have access to either disc: Windows 7 - Repair Disc download
a) Insert the Windows 7 System Repair DVD or Installation DVD and reboot.
b) Select the correct keyboard input method and click 'Next'.
Note: If you are using the Windows7 Install DVD then at the 'Install Now' prompt (Do not pick the Install
Now option) instead choose the 'Repair your computer' option located in the lower left of the dispay.
c) The System Repair tool will search for a valid operating system and will report that "Windows found problems with your computer's startup options. Do you want to apply repairs and restart your computer?"
d) Click 'Repair and restart' and reboot again to the Windows 7 System Repair environment.
e) Click 'Next' at the keyboard selection prompt and when the 'System Recovery Options' screen appears verify that the "Use recovery tools that can help fix problems starting Windows" is selected.
Note that on your Dual Boot system there now should be only one operating system listed. Click the 'Next' button.
f) Now from the menu list select the 'Command Prompt' option.
g) At the DOS prompt type the following three commands:
bootrec.exe /fixboot (may return an 'Eliment not found' message)
h) Close the command prompt window and click the 'Startup Repair' option.
i) The repair process may take some time, so wait until the process completes at which point you will see two messages "Windows cannot repair this computer automatically" and "Startup Repair cannot repair this computer automatically".
These messages are the result of the radical changes made by removing the other drive. Ignore the Send/Don't send options.
J) Close this message window by clicking on the X in the upper right corner of the Send/Don't send window. Next click on the 'View advanced options for system recovery and support' option and from the main menu once again click 'Startup Repair'.
This time the repair process may only that a few seconds and when prompted "Startup Repair could not detect a problem", click 'Finish' and run the 'Startup Repair' option one more time, click 'Finish', and then remove the System Repair DVD and click 'Restart'. Reboot the computer.
hope this helps

However, this error can also occur because the computer hardware, the peripherals, or the drivers for those devices are incompatible with Windows 7.
