I've got a new PC and I've installed knoppix 3.9 on it. Knoppix detected the SATA HDD which I partitioned using qtparted. I used the ext3 filesystem. The install process wrote the boot record the the MBR. I then tried to boot up without the live cd and I get the the following message: "PXE-E61: Media test failure, check cable"

HD is Western Digital WD1600JDRTL
Motherboard Intel D945GNT

Any ideas how to fix this?

Thanks.
