Windows 10: Windows boot priority and BOOTMGR problem.

As you can see, my disks are a bit of a mess, as it's an old PC with old HDDs.




The problem: I'm trying to merge all the partitions in Disk 0, but I can't wipe drive C: because it has an old and corrupted version of Windows 7 that used to be my main boot device. I tried to set the drive to Inactive using DISKPART in order to wipe it, but that makes the bootup broken as it requires C: to be active. I've had to boot from a USB just to get to CMD to set it as active again. I'm not sure if it has something to do with BOOTMGR or anything, but any help would be welcome.



I want a way to be able to format C: to merge all Disk 0, and to merge those small, unused allocations.



Thank you.

Boot Problems

Just out of interest, what got you the BIOS screen?

And in the BIOS, is everything set correctly, like is the raptor master, caviar slave, etc etc? And is the master set to boot up windows first in the boot priority list?

 

Bootmgr ??

Hi BadrAl-harbi,

Thank you for posting your query in Microsoft Community.

This message usually indicates that the boot sector is damaged or missing. The boot sector is a region of your hard disk that contains information that is used to load your operating system. If a boot failure is
detected when your PC is starting, you may receive this error message.

Which OS are you are currently in?

Did you try the same step to install windows 7 from a DVD? I suggest you to perform the steps again.

• 
  Insert your Windows 7 DVD into your DVD drive and restart the system.
  
  (If you did not make a "Recovery DVD", borrow a like version of the Windows 7 DVD from a friend).
  
• 
  Boot the PC using the DVD by pressing any key when prompted.
  
• 
  Verify your language is correct and click
  'Next'.
  
• 
  Select the option named 'Repair your computer'.
  
• 
  The repair option then searches for the Windows Operating System. Once it has completed click
  'Next'.
  
• 
  Under Recovery Tool, choose the option named
  'Startup repair'.
  
• 
  Windows will "try" to repair your startup problem and will prompt you to restart the PC.
  
• 
  If you still get the "BOOTMGR is missing" error then repeat steps 1 to 7 again.
  
• 
  Restart your system to finish the process.
  

Do let us know if you have any other queries pertaining to Windows in the future. We will be happy to help.

Thank you.

2nd Options

Try to enable/disable Windows boot manager. Used CMD

Step 1: Type cmd in the search box, and then right-click Command Prompt and choose Run as administrator.

Step 2: Type the following commands in the Prompt and hit the Enter key after typing each one command.
