Can't Boot Live CD - SATA Drives?
What's the Live CD you are using ? Some old version of boot cd don't support sata drives and this may cause some problem.
Also, it's possible the BIOS settings are bad, with some SATA and IDE motherboard, you have the possibility to set BIOS settings with SATA enhanced and others ... (don't remember exactly). This was I reason I had some problem to boot live cd.
A good live cd is the Knoppix, the hardware detection is very good. I use the 'FCCU gnu/linux boot cd', it's a Knoppix 3.9 modified.
