From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0) Description of problem: I am attempting a clean installation using a downloaded CDROM image. The bootable CD is recognized, and anaconda asks the usual language, keyboard, and mouse questions, then it asks what medium I will be installing from (CDROM, NFS, FTP, etc) and I select CDROM (the very one I booted with). I then get the message: The Red Hat Linux CD was not found in any of your CDROM drives. Please insert the Red Hat Linux CD and press OK to retry. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Reproduced using SCSI CD-ROM and from ATAPI/IDE CDROM 2. Reproduced again on a different computer (my laptop) 3. I noticed that if I boot from the ATAPI CD-ROM, when I select the CD-ROM installation option the SCSI CDROM light blinks. The opposite happens when I boot/attempt insutall from the SCSI CD-ROM, so I tried putting copies of installation CD-ROM in BOTH drives at the same time- but the installation CD still wasn't recognized as an install CD. Actual Results: Cannot proceed past this error Expected Results: Proceed to partition definition, region selection, finally to package installation, etc. Additional info: The error message: "The Red Hat Linux CD was not found in any of your CDROM drives. Please insert the Red Hat Linux CD and press OK to retry."
When you booted from the CD, have you tried entering "linux mediacheck" at the prompt instead of going to installation? This will ensure that your CD was burned without any problems. Unfortunately, CD-R's have a tendency to degrade over time, especially if you leave them out in a well-lit area; even if your burner thinks everything went OK, it is not unusual to still have a problem on the CD-R where data is corrupted. I have had this problem with a variety of drives and discs. The mediacheck is an absolute must-do.
