Hey,
I got an A8n-Sli Deluxe and nanoboot was working perfectly, but no way to boot with XPEenoboot.
I tried the "nomodset" parameter with just a few more lines at boot and a green screen.
I removed my brand new *crappy* MSI nvidia GEFORCE GT610 and tried with my old Nvidia 8800 GTS.
XPEnoboot is now working flawlessly. Migration 5.0 to 5.2 in progress
cheers
