    Bootmgr is missing error after changing partition drives Need Help!!

    Hi, i'm new here and I made an account for the sole purpose of getting help on this situation i'm having right now. Yesterday, I wanted to delete my system reserved partition and I followed a guide to do so but I ended up messing up my partitions. I got the Bootmgr error when I would try and boot up, so I looked for solutions on solving this issue but I have no luck yet. I tried the Windows 7 recovery disc recovery options (startup repair and command prompt) and I tried to change the boot order in the bios but to no avail did it help. One thing I should note is i'm able to successfully boot up from the Windows installation disc but I cannot boot up from my SSD because I messed up the partitions status's Does anyone know how I can reverse this so I can boot up from my SSD instead of my disc everytime? One more thing I should say is I have a second hard drive, a mechanical 2 TB one, and I think I messed up something on that too.

    You'd never want to delete or mess with the System Reserved partition since it boots Windows, not until it has its System Active flags moved to C first so that C can boot itself. Here's how, so you can see if it can still be done:

    Unplug all other HD's except WIn7 HD.

    Mark C Partition Active (Option Two) then run Startup Repair - Run 3 Separate Times until Win7 starts and C partition holds the System Active flags.

    The System REserved partition can now be deleted and recovered if desired using Partition Wizard Resize Partition - Video Help.

    If that fails, mark the System Reserved partition Active and try the Startup Repairs to revive it - if necessary recreate the partition using the Win7 installer Drive Options shown in Steps 7 and 8 of Clean Install Windows 7, use Diskpart to mark it Active then run the 3 repairs.

    When you plug back in other HD's make sure Win7 HD remains set first HD to boot in BIOS setup, no other partition is marked Active except C. Partition - Mark as Inactive
