Hello. I have been dual booting Manjaro and Windows 10 for more than a year switching to windows 10 in between for certain applications. Recently after an update the grub wouldn’t detect the windows installation. I tried update-grub without any luck. I am able to use Manjaro without any issues but i couldn’t boot into windows.

I installed an additional SSD(250GB) and migrated my windows 10 OS. I installed Manjaro after that.

For some reason, osgrabber is able to detect old windows files of disk 2 but not disk 1. Earlier it used to detect both even though only disk 1 installation was bootable.
