I installed Linux on my third hard drive. Then I took out the other two hard drives and Linux would not boot anymore. Do I need to reinstall grub or edit the /boot/grub/menu.lst? It says vmlinuz-2.6.15-23-386 file not found when grub comes up. that kernel is on the third hard drive though. I did not move the the third hard drive with Linux installed to another plug on the ide cable or another ide cable. I am using a live cd and I am able to edit the configuration files if I need to. Here is my /boot/grub/menu.1st: ubuntu@ubuntu:~/Desktop/v/boot/grub$ cat menu.lst # menu.lst - See: grub(8), info grub, update-grub(8) # grub-install(8), grub-floppy(8), # grub-md5-crypt, /usr/share/doc/grub # and /usr/share/doc/grub-doc/. ## default num # Set the default entry to the entry number NUM.
