Problem while installing RH9

[Együd Csaba <csegyud freemail hu>]

Hello,
I'd like to set up RH9 on my Compaq Presario 920EA notebook. I've downloaded
the binary iso images and burned the cd-s under WinXP. The disk boots the
system, which asks me about the language of the installation process and my
keyboard layout. Then it asks me about the installation media to use. When I
press Enter on Local CDROM, it says that there isn't any RedHat Install
CD-ROM in any of my local CDROM drives.

What can be the problem. Can it be that the integrity of the image is bad?
Can a demaged CD ROM be bootable?
How can I check the integrirty of an iso image undre XP?

Thank you in advance.
