Ubuntu Constant Reboot Error

mup.sus error post, a dual boot system is great to have on many levels.  Recently, my Linux box running Ubuntu 10.04 ran into problems booting, sending it into a constant reboot loop.  After doing some research, I learned that the problem pertained to the update that was applied to the bootloader GRUB.  A bootloader is basically the section of code that loads a particular operating system. Now came the fun part where I had to figure out how to fix the problem.  Fortunately, I came across the answer.  Use the following information after booting in via a Live Disc. ** SDA1 should be switched with the location of the hard drive where your Linux distribution is installed.  This can be found by going to opening Disk Utility. sudo mkdir /media/win sudo mount /dev/sda1 /media/win sudo mount -o loop /media/win/ubuntu/disks/root.disk /mnt sudo cp /mnt/boot/grub/grub.cfg /mnt/boot/grub/grub.cfg.copy sudo chmod +w /mnt/boot/grub/grub.cfg gksu gedit /mnt/boot/grub/grub.cfg Remove all lines in the file from the start of the file up to, but not including, the following menuentry ### BEGIN /etc/grub.d/10_lupin ### Reboot into your Linux box and all should be repaired.  Until next time … -D
