I recently upgraded to 12.10 and can no longer boot into Windows 7. When I select the Windows 7 partition in grub I get "error: device format "ldm... invlaid: must be (f|h)dN, with 0<= N < 128" (... is a bunch of numbers and characters) then I press any key and get "a disk read error occured, press ctrl+alt+del to restart". I have done a little research and this bug seems to be similar to mine https://bugs.launchpad.net/ubuntu/+s...2/+bug/1061255
I have Ubuntu 12.04 on a usb that I can boot into for boot repair ("Workaround 3" in the above post), I just want to make sure that other people think that is a good idea, because I am fairly new to Ubuntu/grub. Thanks for any advice!
