"Bootmgr is missing" on boot up?

Hi, I was doing some stupid stuff like messing with disk management and was curious was setting active partitions would do. I set my memory drives as active for a stupid reason, then, after reading what setting as active partition does, I set my ssd boot drive as the one active.

Now "bootmgr is missing, press Ctrl alt del to restart" shows up in the top left corner.

I went into boot options and set my ssd as 1st priority yet it didn't change anything. I've also tried hold f8 and manually booting my ssd and that didn't change anything as well.


I've tried "repair boot up" via windows 10 installation USB yet nothing is working out so far.


Any help would be greatly appreciated. Thank you.
