I was installing Manjaro on my external hard disk it was a smooth sail until a guy (don't know what to call him **) smashed the live usb.
So tried booting to windows to fix this but Grub rescue menu showed up,
as installation was done on my ext disk I connected it, now this GRUB menu showed up,
I figured where the grub was installed using the ls, but sure not to what to do next.
(don't know what command to give next)
somehow I made the usbstick to work and booted live Manjaro, Please help me to boot windows (I guess I need to do erase grub but since it was installed on external disk I don't know what I should do first), then I'll probably delete and recreate the partition in the ext hard disk. (or if was able to fix the windows Grub menu error I guess I use GParted directly in this live session)
