Change Multi-Partition Configuration

I have attached a file to show the current configuration of my hard drive. Historically, I purchased the computer with Vista OS and then added the Windows 7 and Windows 10 partitions later as as these OSs became available. I am now running out of space on my hard drive and want to delete the Vista OS and expand the Windows 7 and Windows 10 partitions. Using the MiniTool Partition Wizard I change the Windows 10 partition to 'Active' but when I rebooted my computer it would not boot - the error message was "BOOTMGR is missing, Press Ctrl-Alt-Del to restart". I used the MiniTool bootable disc to change back to the original settings and the computer booted normally.

I would be grateful for assistance to achieve the dual boot (Windows 7 and Windows 10) configuration that I want.

Many thanks for your assistance. That solved the problem and I will not be able to delete the Vista partition and adjust the size of the partitions for Windows 7 and Windows 10.

You'll need to explain more ...WHY? or do you mean you changed your mind about that ?

I assume you are booting into Win 10 now with no multiboot (dualboot) menu ?

I made a typo in my response to topgundsp's advice. I meant to write "I will NOW be able to delete......". Hence my problem was solved. I am now using the C partition containing Window 10 as my boot partition and I am also able to boot into Vista and Windows 7 when needed. I will delete the VIsta partition when I actually run out of space on the hard drive. Thanks everyone for your advice.

Nice :) thanks for reporting back and confirming it works for others too.
