Re: After installation, "PXE-E61: Media test failure, check cable"
That error translates to "I can't find any bootable hard drives so I've moved on to try to do a network boot, and that ain't workin' either".
You need to check all drive power and data cables, verify that the SSD and 2 hdds are seen in BIOS, and that the BIOS boot sequence is correct. It MAY be necessary to set the "boot" flag on the SSD, if that is where you installed grub.
(FYI, I have a PCI SSD, OCZ RevoDrive, and my BIOS does not recognize it as a bootable device, therefore I had to install /boot on a different SATA device.)
