Solved Boot MGR missing, only boots with a bootable usb in system

[tj1990]

Hi,

Recently had to format from windows 10 back to 7, until the black screen of death happened so formatted 7 again.

Everything functions normally except that it will not boot unless a bootable usb is selected as first priority.

If you press no buttons when told to after a few seconds it goes straight into windows.

What do i need to do to fix the boot mgr? i tried startup repair and it told me there was no problems with windows, have only tried it once tho does it have to be attempted a few times?

At the end of the day its not a really bad problem i suppose, but would be nice to free up a USB port.

Thanks.


Edit: Windows was installed from a USB if that makes any difference, startup repair also run from same USB.

You can use EasyBCD to move all the boot files to the main drive.

To open Disk Management, press Windows key+r, type diskmgmt.msc and press Enter or click GO.

Make it full screen.

Here it is. the E drive is an external hard drive, thats not always plugged in.

You can use EasyBCD to move all the boot files to the main drive.

i just had a look at that, is it really that simple ? :O

I'm not sure at this point that the BCD location is your problem. Can you go into the BIOS and see what the boot drive order is? Try to spec the drive with your C partition as number one boot device. You might even switch the wires in the box so that it's Drive 0, though normally that doesn't matter. Was the E drive plugged in when you did the 7 install?

The boot order has the USB drive at first otherwise it will never go past boot mgr missing. the 250gb SSD is the drive with windows on it.

If i take out the USB and leave the SSD as first it gets the mgr missing error.

E drive was not plugged in.

i see that F says system, could that be the issue?

That does seem strange. I would disconnect the drive and see how the machine boots or what startup repair says then. If there is a problem I would run the bootrec commands from the WinRe command line, with all other drives disconnected.

which drive would you like me to unplug ?

 

[paul1149]

To straighten this out I would disconnect all drives but the one with the C partition, to make sure that the BCD is on that drive along with the Win7 installation.

so i didnt get around to unplugging the drives but i used easy bcd and its fixed. It now no longer needs a bootable usb plugged in to boot!

although i did encounter the black screen of death again, but i was able to system restore this time.

I formatted to fix the black screen of death issue -_-

If it happens again hopefully new GPU Drivers will sort it out.
