What's the Windows 7 equivalent to the above solution? Therefore, I don't know how to get to a point where running dpkg-reconfigure grub-pc would work, and since the computer's not mine, I don't want to experiment too much. pureblood's solution doesn't work, since mounting /dev/sda1 to /tmp/drive and then cding to the directory shows there's no native /dev, /proc, or /sys directory, and skipping to sudo chroot /tmp/drive fails with the message: "failed to run command '/bin/bash' no such file or directory" (I'm guessing this is because Windows doesn't have bash). However, lacking that thumbdrive, the grub rescue prompt still shows up when I try to boot natively, with an error showing a whole bunch of numbers and letters. Pureblood's solution from post 27 worked to correct the Lubuntu grub installation, so I can now boot to Windows and Lubuntu 14.04 from the thumbdrive. (Short version as to why: the computer's not mine, I'm just on long term loan from a friend.) The primary computer's harddrive has Windows 7 on it, and I'm running Lubuntu from a thumbdrive installation. I encountered this same problem when updating Lubuntu 13.10 to 14.04 on an Asus netbook. I can only boot from BIOS by selecting the Ubuntu drive and not the 'default' So do I need to run grub-install -recheck /dev/sda1 to reinstall grub there? My default boot drive should be the /dev/sda - (Windows ) and then Ubuntu is on /dev/sdb.
