Booted to OS 9. Now stuck. Startup Disk doesn't show OS X as a boot option.

I assume you want to startup in 10.2.

Depress/hold the X key at startup & it should boot into 10.2.

Another way. Depress/hold the Option key at startup which activates the Startup Manager. In the window that opens, select the 10.2 HD icon & click on the right Arrow.

Another way to get there, using the method you expected to work, is to update to a later version of Startup Disk Control Panel. The version you are using does not understand how to boot Mac OS X directly:

TA20415- Mac OS X, Mac OS 9: Use Current Startup Disk Control Panel or Mac OS 9.2.2

a link to download of the latest Startup Disk Control Panel is included in the article. It is compatible with every version of OS 9.

Thanks to Grant for the link,

And although this question is now answered, I've used this version of the Startup Disk CP in OS8.6 on my rev.A iMac G3 (Bondi Blue). This gave me OS8.6, OS9.2.2 and OSX 10.2 (each in their own partition, all within the first 8GB of disk).

Just in case it helps someone else.

Thanks for that info, Simon Teale. I did not know it worked as far back as 8.6.

Did you happen to try anything older as well?

Grant,

Sorry, no I didn't, but then my choices were OS8.5 or OS8.1. Both rather poor imitations of 8.6.

Can't remember the big changes in 8.5 or 8.6 and whether they would be required for the CP to work.

Just one caveat, might have been the Startup Disk CP from my MDD (OS9.2.2+) that I used. But I definitely remember also doing this before I bought the MDD.
