Installation problems

I downloaded the recent version of the non-commercial QNX
and tried to install it.

After choosing the partition and the bootloader,
I get the following error message:

DINIT: can’t open drive ‘/dev/hd0t79’: No such file or directory
/qnxbase/safe-config/x86/bin/dinit -hq /dev/hd0t79: failed (12292 256)

When I boot from the cd, this partition does not exist as well.

Can anybody give me a hint what to do?

Sounds like your disk/controller may not be supported. Can you give more information regarding the hardware?
