I had windows and debian installed alongside on the same SSD and working seamlessly. During my experiments I played with Windows installation from USB and (of course) it ended up with grub rescue mode.
I'm not certain, but it is possible that in frenzy I did:
grub-install /dev/sda6 # (where /dev/sda6 is my root linux partition)
because now, after some playing in terminal:
detects only Windows parition which resides on /dev/sda1. During my search I found this page and I would like to ask whether it is safe to zero out MBR as it is described in the link. I mean, (since I don't know when was the linked post written) are those numbers from commands:
dd if=/dev/zero of=/dev/hda bs=446 count=1 # and dd if=/dev/zero of=/dev/hda1 bs=512 count=1
still correct? I wouldn't like to make things worse than they already are...
