Cannot boot from install cd

[Endre Szabo]

Hello

Having the install cds written correctly, I inserted
the cd #1, set the boot order with the cd to be first,
then booted. The process skips the cd (as there were
nothing in the drive) and continues from the hdd. 
Tried with another bootable cd (a livecd), the same
happened.
I've got a Philips CD-DVD writer as cd unit.
What can be the problem?

Thanks
Endre
