I have an iBook G3 and it had Mac OS 10.1.5 and Xubuntu installed.

When I would turn on my computer there was a screen asking me to

click l to start with Linux

click x for Mac Os

click c for CD

 

Than one day I upgraded my Mac OS from 10.1.5 to 10.3.Now 10.3.9.

But when I open the computer now the dual boot screen is gone.

It simply start up with Mac Os.

Why did that happen?Is Xubuntu still installed on my computer?

That's a PowerPC machine, so no BIOS, EFI, MBR etc. However, an overwritten/deactivated bootloader could very well be the problem. I don't have a lot of experience with PowerPC Macs, especially running Linux on them, but my guess would be that you could boot from the Xubuntu disc and reinstall the bootloader - give it a go and see if there are any repair or rescue options.

 

Also, you could try holding Option during startup to get a boot selection menu, but I don't know if the firmware will recognise the Xubuntu partition.
