I have the same Gentoo version installed on 16 machines. Using the same 3 DVDs created in the same way with the same CentOS version and 2 same brand portable DVD-ROMs, I have managed to get the installation on 15 of them. The 16th is showing up this error
Kernel panic - not syncing:VFS: unable to mount root fs on unknown block(2,0) after selecting boot from the DVD in the bios boot menu and booting up until I select the install option. Once the option is selected, the error message appears. I wanted to know if there is an error guide for the
unknown block numbers or would like to find the root cause for this.
There is no difference between the machines' BIOS versions, but I don't know how the first Gentoo install was performed.
