I am having this same problem, and it is very frustrating because grub cannot boot either linux or windows.
For me, this started when I was trying to change my external hard drive (which has linux on it) to be able to boot on any computer. I tried it on my desktop computer, and it booted successfully--once. After that, I always had this problem. A few days later I noticed that my SuperGrubDisk flash drive partition started having the same problem--after using it in the same desktop computer. I think that it's a drive access problem that may be solvable with the help of this link http://ubuntuforums.org/showthread.php?t=442945 ...but I was never able to make it work. Any help is appreciated. ** Changed in: ubuntu Status: Invalid => New -- fdisk show FAT16 in a ext3 partition https://bugs.launchpad.net/bugs/329509 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
