Used a kickstart script to install the system, got slightly different results. Upon boot, I see: L 99 99 99 ... 99 and so on. This could be due to a correctly configured BIOS (set to AHCI). However, the installation boots when the installation disk finds an installed copy of CentOS on the hard drive? For the moment, I am carefully fiddling with grub. -------------- next part -------------- An HTML attachment was scrubbed...
