Recover dual boot of Ubuntu after MAC OSX upgrade to Leopard

Asked by dplaisier

I've been dual-booting Ubuntu and MAC OSX (Tiger) on my powerbook for years... flawlessly... yaboot solution is great! Recently, I "upgraded" to OSX 10.5 (Leopard), which seemingly has also "upgraded" the boot block contents. The Ubuntu partition is still there, but now I'm not given the option to boot it anymore... goes straight to OSX. It appears that I have to do the ybin -v from the Linux side again (since presumably the /etc/yaboot.conf file is still there also). However, how do I "get to" (i.e. force a boot to) the "Linux side" in the first place (sorta like "forcing" a boot from CD w/ the "C" key, but instead of CD go to the Ubuntu contents... which appear as disk0s4 and disk0s5 on my MAC diskutility)?

There is either the option to hold down the Option (Alt) key at boot to select the boot partition or maybe resetting PRAM is sufficient if your yaboot partition is the first one. Please also see about how to restore yaboot.

That does it! Maximum apologies for not knowing my own Mac (the 'option' key... but I *did* know about the 'c' key... sigh... must be getting senile). Nevertheless, I now know about this wonderful forum! Outstanding. Thanks.
