Hi all, All resolved now. Thanks to Paul for pointing out the basics :) This had nothing to do with the e1000e as I thought earlier. It has to do with the AHCI mode set for the SATA interface. These where the steps I took to resolve it: 1. Start Laptop 2. When first boot screen appears, press F1 to get into the BIOS setup 3. Go to Config > Serial ATA and change AHCI to Compatibility 4. Press F10 to save and reboot Now it boots and installs. Since CentOS has an older kernel than RHEL 6.1 I am not able to get screen resolution etc to work so I will run RHEL on this one as Keyboard keys, Web cam, Sound, Ericsson WLAN, all just works :) Thanks a lot for your help peeps.
