Thanks all,
very good link RTFM, thanks.
TCS, the boot feature I have was installed automatically by SuSe - quite brilliant but was always defaulting to SuSe- didn't want to complicate my life with a proper boot program since I only use SuSe for fun/learning hence was wondering if there was a simple solution.
The winner is Tinstaafl - it is using Grub and editing the loader did the trick - thanks a million.
Cheers
Charles
