I recently updated my computer using the modified 10.5.5 update package for AMD. Right after updating when I restarted the computer, it was not loading bootloader anymore. I ran the fdisk commands and such but nothing seems to work. The only way the computer is booting is with the dvd still in the drive. Without it, I just get a blinking cursor. How do I fix this? I am running leo4All v4.1.1 with Chameleon bootloader.
