Check Point and GRUB-problems

This post serves more as a reminder to myself about Grub rather than providing new and exciting information.

The /boot/grub/grub.conf file is either empty, or corrupted.

Check Point FW boots into grub command prompt – Manual boot

If all you can see is a grub command prompt you need to do the following to manually boot the firewall.
1) Mount the root partition
2) Specify Initial RAM Disk
3) Specify Kernel to load
4) Boot

grub> find /grub/stage1
(Returns something along the lines of (hd0,0)
grub> root (hd0,0)
grub> kernel /vmlinuz (Press tab and choose correct architecture)
grub> initrd /initrd (Press tab and choose correct architecture)
grub> boot

* The operating system should boot and a new ‘/boot/grub/grub.conf’-file should be generated.
* The default=X in /boot/grub/grub.conf refers to title number X (First title is 0, second title is 1 and so on)
* vmlinuz in /boot/ is a symbolic link
