Installing WIN 98 onto a SCSI Hard Drive

Hi .I'm trying to install either WIN 98 or WIN ME onto a Seagate SCSI 2GB Hard Drive on a Dell dimension PC. I've run fdisk, scandisk, and formatted C;, with no problems. It identifies my CDROM as E:?, but when I try to run setup, I get a message saying that there is no boot sector, and that setup requires the largest executable program to be at least 450000bytes to run. I do not have the option in Boot sequence to boot from CD.

Help???

Thanks,
