→Fix the GRUB with the systemrescuecd
grub must be installed on all other drives to give the capacity to operate the system. To reach the boot menu of the bios, will depend on your hardware ... F12 under dell, Acer Esc, F11 from msi .... my sme is with Raid1 so I have two drives, you will need to adapt my example to your the number of disks.

==Fix the GRUB with the official SME Server CDROM ==
I presume that your SME Server is on a RAID1 of two disks (sda, sdb), otherwise you will have to adapt this HOWTO.
* start the system with your official SME Server CDROM
* give at prompt : '''linux rescue'''
* set your language and your keyboard
* set to '''no''' the start of network interfaces
* set to '''continue''' the question about how the system is mounted in /mnt/sysimage
* set to '''ok'''
* give at prompt :
chroot /mnt/sysimage
su -
* then you can perform
grub-install /dev/sda
grub-install /dev/sdb
do it for each disk you have on your server
* to exit
exit
exit
halt
then you can test if the grub is present on your drives.

==Installation of grub on a new disk==
When your system is started you can install grub by the command Line on any other disk you want. You have to change by the name of your new disk.
