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!

 

Is this perhaps a problem that the SSD was reformatted with another window machine?

 

Can anyone please help?

    Where is this Boot MGR located?????

Check your Boot Order in the BIOS and make sure you are booting from the correct drive.  If the machine is trying to boot from a drive that is not bootable you will receive this message.

Hi - I'm Callum.

 

 

 

First of all Kilroy is right, it could be your boot order! You will have to check your boot order to make sure you are booting off a CD (If Windows is installed on a CD) or that you're booting off a USB (if Windows is installed on a USB). You can change your boot order whilst booting up by pressing one of the following : ESC, F1,F2,F8 OR F10. Which key to press depends on what brand your machine is.

 

If that fixes your problem then great! If not, then carry on reading. 

 

If your boot order is correct and all cables are correct and it doesnt even install on a different hard drive and different optical drive, this could point to possibly corrupted files on your CD or USB. Did you buy a retail version of Windows 7/10? If you downloaded it off the internet via ISO, I recommend redownloading it to a fresh CD / USB as the files could be corrupt on the old one.

 

If you know for sure that the files aren't corrupt, I suggest taking a look at this thread: http://www.tomshardware.co.uk/faq/id-1945283/fix-bootmgr-missing-error.html 

 

Let me know if it works please.

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
