YDL-4.0 installation problem on G5

Wed Apr 6 07:38:57 MDT 2005

Hello,
I want to install YDL-4.0 on my G5 machine. I've downloaded the four iso
images (yellowdog-4.0-orion-20041107), burned them on CD's, and start
the instalation (install-g5 option). I choose to install 'everything'
and partitions made automatically.
I've encountered a problem at the last stage of the installation, when
the machine reboots itself it can not find the installed image. 
Is it sound familiar to anyone? Please help.
Thanks,
Tzachi.
