Boot MGR

BOOTMGR Missing

I would like to install an operating system, but cannot even

 

do this!

The computer had windows 7 on it. The SSD ("hard drive") was

 

removed and reformatted using another computer.

Now I cannot even load an operating system because after

 

powering on I just get a message:

"Boot MGR is missing

Press Ctrl Alt Del to restart"

So this is what I have done so far:

  1. Checked all cables
  2. Tried to install windows 10 from a CD
  3. Tried to install windows 7 from a CD
  4. Physically changed the optical (CD/DVD) hardware
  5. Physically changed the SSD "hard drive" to a new SATA

     

    hard drive
  6. Cleared the CMOS Setting by moving the jumper pins and

     

    restarting the computer
  7. updated the BIOS (successfully) from a USB.

Each time I start the computer I still get:

Boot Mgr is missing!

Can anyone please help?

Where is this Boot

 

MGR located?????

The Boot Manager is installed in the first few sectors of the HDD (or SSD or SSHD). Whatever was done on this "other computer" has wiped out the Boot Manager.

I suggest that, while installing Windows (i.e. booting from Windows installation media), when you get to the scene where you select the partition to install to, make sure that you delete *all* existing partitions. When done, you should see only a single entry for unused space on the HDD. Select to have Windows installed to this unused space. This should restore the Boot Manager.

Let me know if this fixes the problem. There is a second possibility, but I won't go into it until we exhaust this one...

Thanks for your suggestions.

I have solved the problem

The SSD is so fast I did not notice the line "press any key to boot from ..."

this instruction appears for less than one second and then it is replaced with "boot mgr is missing"

hahaha

so I pressed the space bar and it worked

Thanks again
