I have multiple HDDs in my box, one of which being a Win7 install. After installing 64bit version on to my old 9.10 drive (full wipe of drive) and it says everything went well. Afterward though when I rebooted it just hangs at a blank screen. I thought maybe it just didnt load the boot images so I let it sit for up to 40 minutes and realized it should have at least given me an option of which OS to load by now.
After reading a little on the forums, I booted in my live-cd and tried "sudo update-grub" which gave me the following error
Any suggestions?/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
