log in as a root (not advisable but you have to) and use this command

root@localhost# cd mnt

check if cdrom folder is there or not? if not use following command

mkdir cdrom

go in to cdrom folder through cd cdrom command

and then use the command as below

mount -t iso9660 -r /dev/cdrom /mnt/cdrom

it would be work.

thanks
