I'm sure i cant be the first with this problem, but after searching for about an hour or so im just gonna ask directly, sorry if this is a duplicate request. I'm Building a killer system for a friend of mine. Windows 7 64bit Ultimate for System Builders Asus Crosshair III Forumla 790FX Quad Core AMD 3.4GHZ Phenom Black 8GB DDR3 1600OC Dual Sapphire Radeon HD5850's 1GB DDR5 in Crossfire configuration LG Blu-Ray DVD burner SATA Lite-On Blu-Ray Reader SATA Dual 160GB WD Blue in Raid 1 Single Seagate 1.5tb WinTV HD TV Tuner Here's my problem. Windows 7 Loads from the LG Blu-ray device fine. I click on Install Now and get the following error. "A required cd/dvd device driver is missing." It tells me that i can remove the windows 7 disc to install the driver disc that came with the device, but the device is not recognized to do that. Will W7 installer recognize a USB drive that i could load the drivers to? I have tried using an older SATA Lite-on dvd burner with the same problem... I have also tried using an IDE DVD burner with no luck Thanks in advance for any help!!
