ok
insert suse installation disc
boot into it
start with installation

when installing suse linux do folowing.
install bootloader
install bootloader on your MBR(master boot record of /dev/hda

after install computer will reboot.
you will see a bootloader screen
select a OS you want to boot
if you have dual boot with windows you will have to choose betwen
boot into windows
boot into suse

than the selected os will boot

note: if you have sata disk is sda instead hda

i hope that helps

Hi !

***** BIOS: The Basic Input/Output System is the lowest level interfae between the computer and peripherals. The BIOS performs integrity checks on memory and seeks instructions on the Master Boor Record (MBR) on the floppy drive or hard drive.

***** The MBR points to the boot loader (GRUB or LILO: Linux boot loader).

***** Boot loader (GRUB or LILO) will then ask for the OS label which will identify which kernel to run and where it is located (hard drive and partition specified).

***** The first thing the kernel does is to execute init program. Init is the root/parent of all processes executing on Linux.

***** The first processes that init starts is a script /etc/rc.d/rc.sysinit

***** Based on the appropriate run-level, scripts are executed to start various processes to run the system and make it functional.

In SuSE, it's just a little bit different (Take note of '/etc/init.d' and '/etc/rc.d -> /etc/init.d')...

Please see:

/etc/init.d/rc?.d
