View Full Version : [ubuntu] Ubuntu Server 8.04 installer cannot detect or mount CD-ROM

I am attempting to install Ubuntu Server 8.04 and encountering the following error message:

[!!] Detect and mount CD-ROM

Your installation CD-ROM couldn't be mounted. This probably means that the CD-ROM was not in the drive. If so you can insert it and try again.

Try again to mount the CD-ROM? <Yes> <No>

The same error occurs when I attempt to check the CD for defects. Motherboard is ABIT AI7 with 2 SATA and 2 PATA slots. Hard drive is 750GB SATA, and I have tried with both SATA and PATA DVD+/-RW drives. The Kubuntu 8.04 LiveCD loads fine, and installs fine once the OS is loaded into memory. I have tried several different boot options from searching and none work. There are similar bugs, but with different circumstances (such as external firewire CD-ROM drive as opposed to internal ATA).

Please let me know what additional pieces of information are required to troubleshoot this problem.

Cheers,
mwjones

Edit your boot line and add all_generic_ide at the end.

Unfortunately all_generic_ide does not fix the problem. Currently I have the SATA DVD+/-RW drive in, but have tried it with both. Additionally, since Ubuntu is not yet installed, F6 is required to edit the boot parameters (as opposed to e in GRUB).

I've tried some additional items such as burning to different discs at different speeds, changing the mode in the BIOS (Auto, Enhanced, Combined, SATA Only), etc. A bug has been opened for this issue https://bugs.launchpad.net/ubuntu/+bug/237800

Please post any other suggestions.

Just an update on my end: I have moved on to just using Kubuntu 8.04. For further information on this issue, I guess just follow the bug report. Good luck!

Having a similar issue trying to install Ubuntu Server 8.04. Mobo is an ECS P43T-A2, DVD drive is a Lite-On 16D3S (a SATA DVD-ROM).

The ironic thing is the installer boots just fine from the same drive it apparently can see during install... :confused:

Exact problem here. Looking for a solution. Not really appreciating the irony of being unable to detect the cdrom (DVDdrive) doing the install....

I've heard changing ACHI to Raid sometimes works
