Basically I went into disk management in windows, right clicked on the Ubuntu partition and clicked delete. It was lazy and stupid and now I've lost access to my windows and all I get is
error: no such device: 9a952691.....
entering rescue mode...
Grub rescue>
I've tried various fixes and I can't get them to work.. Help please? Preferably without need for a USB stick or windows disk or anything, can I do it from this screen?
