How new installation work (bootloader):
---------------------------------------
i) The installation tries always to propose bootable system. It means last
installed SUSE should start when you reboot PC. The cause is finishing
installation. (Installation has 2 steps: the second start after reboot)
ii) During installation bootloader also tries to add other installed OS from
other partition to boot menu like chainloader or configfile. (It works only for
GRUB) It is cause why you are not able to select create chainloader from just
installed system. I accept that adding other OS is not ideal and it doesn't
work perfect for adding other distribution like RH or Ubuntu.
iii) If you want still create chainloader from just installed system. You have
to do it manually. :(
How to "create" chainloader from just installed system:
-------------------------------------------------------
a) If you have other installed system your MBR include some boot code and start
some bootloader (in this case GRUB)
b) New installation always tries to modify MBR. It is necessary deselect 3
checkboxes "Boot from MBR" , "Write generic Boot Code to MBR", "Set active boot
flag..."
c) You have to select "Boot from Boot Partition"
d) After reboot your PC start as usaully with last installed OS and there is
necessary to modify menu.lst manually. It means add chainloader to new OS (just
installed but only the first part)
e) You can reboot PC and select your "chainloader". The installa will be
finished and you have installed new OS which is bootable from previous OS (e.g.
Ubuntu, RH, or other SUSE)
