Boot MGR is missing help

[brandab]

So I recently marked a partition active while creating a new partition and now my boot manager is missing.
I've done a lot of research already, I've gone back into CMD to rebuild it manually from the recovery disk and all of the bootrec /fixboot bootrec /fixmbr do not work for me, it's still missing after it supposedly fixes the mbr

You must not have two active partitions on the Windows boot drive. Only one partition can be active, and in your case that's where the Boot Manager is located, it's usually the partition named "System Reserved"

Boot your computer from "MiniTool Partition Wizard Bootable CD". Download the free ISO file from here:

Create a CD from the ISO file with IMGBurn: http://www.filehippo.com/download_imgburn/

Boot your computer from that CD. Select the new partition which you made "Active" and make it "Inactive".
Whilst there, check that the "System Reserved" partition is "Active". If it's not, make it so.

Remove the CD and reboot.

Thank you for the response, I was able to figure it out on my own last night. I had to rebuild the bcd manually, but if I did the wrong combination of "bootrec /fixmbr" "bootrec /fixboot" AFTER exporting the old bcd and rebuilding it, it would still say I have 0 Windows installations and give me the BootMGR is missing. So I tinkered with it until it said I had 1 Windows installation after bcd rebuild and guessed which bootrec /fixmbr bootrec /fixboot bootrec /rebuildbcd was causing it revert to 0 Windows installations.

I have one more question though...
If I did all of the above^ in my C: drive, should I still mark "System Reserve" as active? Because, all of the rebuilding of the bcd and stuff was done in my C drive, and don't want to go through this again lol

The "System Reserved" partition, if it exists, should be the active partition since that's where the boot manager is located.

However, if your system is no longer giving you the "Boot Mgr Missing" error and Windows is starting okay, you can safely assume that the partition is already active, so you don't need to do anything else.
