Ok, i have a usb flash drive where i have a .iso of CentOS 6.0 LiveCD.
When i boot it up with the usb i get the error after the logo and spinning circle i get this error:
"Root device not found
Sleep forever"

I have booted both ubuntu, win8, magicpartion (?) with this mobo.
Havent changed anything since i installed ubuntu on the machine.

Have a ssd connected to the mobo with sata & no extra usb/ssd/hdds connected.

Dont know what to do...
