Boot issues with boot camp

[brant7474]

I tried to start my macbook today, which has mac os 10.4 and windows XP installed on it, and it refuses to go into MAC OS. When I hold the options key down to select the partition, it doesn't matter which partition I select, it boots into XP. I have the settings selected in the control panel start up menu to boot to mac os as well, but it doesn't work. I've had bootcamp installed for almost a year with no issues. Anyone know how I get back onto MAC OS?

I think I found the issue. I had just told it to update to MAC OS 10.4.11, and supposedly this update does not mix with bootcamp, causing the MAC OS partition to become inaccessible. Anyone have any experience with this? Solutions appreciated!
