When I tried to boot from my RH 8.0 cd , before I can get on with the installation, I got an error message as follow:

ISOLINUX .75 2002-06-14 isolinux: Failed to get sector size, assuming 08100
isolinux: disk error 01, AX = 42CD drive FF

Boot failed: press a key to retry...

I have partitioned my 2Gb hard drive using Partition Magic Pro 7.0 in to 2 primary partitions in which the 1st 1,799Mb is of type Linux Ext2 and the other 267Mb is Linux Swap
I have also tried to make the 2nd partition as a logical 267Mb Linux Swap or delete all partitions leaving only one DOS partition but still got the same message.
I also tried with RH 7.3 and Mandrake 9.0 and they all have the same problem. The strange thing is that when I use RH 7.0, it still had some error messages but I can still go ahead and install it and get it working without any problem.
Has anyone ever encounter this strange behaviour ? If so, would it be possible that you can shed some light on me ?

Thanks !
