Windows 7: BOOTMGR is missing - help!

BOOTMGR is missing - help!

I woke up to BOOTMGR is missing press ctrl alt del. When I reboot it comes immediately back to BOOTMGR is missing, it does not offer me any startup options, I can't choose a boot to Linux which is one of my startup options, I can't even get it to start to a disk in my DVD player. I always thought that even without a hard drive, the computer would be able to get into BIOS, but that option isn't there either, the Lenovo logo screen comes up followed by the BOOTMGR error screen.

How To Fix

You wouldn't get any massage if your bios wasn't running.
Bootmanager is your startup.
I had that once with a dual boot start up option. Double set like XP or W 7
If you deleted or disabled one of the options it ran into bootmanager missing.
Typical with easy BCD program.
Did you remove every other startup item like USB devices?

You can produce a repair disc on another PC

Hi Len,

Please ensure that there are no USB drives,media cards or any CD inside the system. Kindly disconnect all the peripherals from the system n try again.

If the issue still persists then follow this tutorial below which should help you resolve this issue:

This is odd. I moved the computer to my workbench and it booted with no problem so I took it back to my desk and reconnected everything only to have the BOOTMGR problem reoccur. I took it back to the workbench and it booted fine again. The only difference between the two locations is that at the desk the power comes from my UPS. Could that make a difference? this is baffling. I will try it again at the desk without the UPS late this evening, I have an appointment and can't do it now.

It shouldn`t, but, try just using a surge protector instead.

Solved

I decided to try and figure it out through the process of elimination. It turned out to be a flash drive that was left in one of my USB hubs, it must have had something on it that the computer was trying to boot. All this time and aggravation... I feel stupid that I didn't see that I left the flash drive in my hub in the first place. Thanks for all your help.

In the start-up sequence your bios tries the several devices listed in it's priority table.
If there is something like a USB device connected it thinks it's a drive and tries to boot.
You could change that in BIOS, like not allowing to boot from USB or for example the internet.
Or at least put your DVD and HD prior to USB

Hi Len,

As I mentioned in the reply sometimes system tried to boot from any external USB, media card or CD as BIOS by default is set to boot from external drive in most systems.

If you wish to continue using the system with the external USB drive connected then change the boot sequence to boot the system from internal harddrive now.

If you have any further queries feel free to reach out to us.
