Sometimes, especially with older CD-ROM drives, the installer may fail to boot from a CD-ROM. The installer may also — even after booting successfully from CD-ROM — fail to recognize the CD-ROM or return errors while reading from it during the installation.
There are many different possible causes for these problems. We can only list some common issues and provide general suggestions on how to deal with them. The rest is up to you.
There are two very simple things that you should try first.
• If the CD-ROM does not boot, check that it was inserted correctly and that it is not dirty.
• If the installer fails to recognize a CD-ROM, try just running the option Detect and mount CD- ROM a second time. Some DMA related issues with very old CD-ROM drives are known to be resolved in this way.
If this does not work, then try the suggestions in the subsections below. Most, but not all, suggestions discussed there are valid for both CD-ROM and DVD, but we’ll use the term CD-ROM for simplicity.
If you cannot get the installation working from CD-ROM, try one of the other installation methods that are available.
