As a first step, I would recommend establishing that the download has integrity. As has been mentioned many times in other threads, the conventional wisdom on this is:
1. Download the iso file.
2. Burn the iso file as an iso at a very slow speed. Before burning check the md5 checksum against the established md5 (usually available at the down load site as a separate file.
OK I done that, 2 downloads from 2 different mirrors and both checked against hash. Burned both disks at 1x speed and tried booting from both, all exactly the same!
Install hangs at 'ready' on each of these disks (3 now). Running 'compatibility mode' hangs after a page of info, same spot, on each boot disk. Removed graphics card and connected to onboard video, no difference. Removed wireless PCI card and tried, no difference. Swapped RAM for other sticks, no difference. Tried other SATA ports, no difference. Tried AHCI, Native IDE and Legacy IDE, no difference.
Could it be because my CD/DVDRW drive is of the SATA variety? That's the only thing I can think of, as I'm practically running a 'bare' board trying to get this thing to install.
