I'm having exactly this same problem when installing ubuntu 8.04 LTS server (alternate CD) in both normal, and expert modes.
It boots perfectly fine from the CD-ROM but when it gets to the stage of detecting and mounting the drive, it fails with the error "No common CD- ROM drive was detected" For those wondering, it's not a fault of the burning process on the CD, or any fault on the CD as i've checked the CD against what's on the site, and it checks fine. it is not faulty hardwareeither because the CD-ROM drive worked fine with 6.06 LTS. Only ideas I've seen anywhere suggest that it has something to do wqith the SATA drivers installing and blocking the CD-ROM drivers, but this shouldn't effect me as I do not have any SATA hardware on that PC (as far as I know) I also tried generic.all_generic_ide=1 as an added option but got the message that it was an invalid parameter. Things to note in my case: eMachines i400 400 mghtz intel celeron CPU 256 MB RAM standard double speed IDE (ATAPI) CD-ROM drive set as secondary slave 3 standard IDE hard disk drives ranging from 3.7GB to 4GB in size all properly installed (none are SATA that I'm aware of) worked perfectly fine with kubuntu 6.06 LTS Any assistance would be helpful as I have yet to get any help with this issue -- No common CD-ROM drive was detected. https://bugs.launchpad.net/bugs/195614 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
