I've got a Windows 7 installation image on my USB hard drive, which is set up to be bootable. I know it works because I've used it on several computers, and it works on the computer I'm trying to install as long as the RAID controller is disabled. However, when I enable the RAID controller and attempt to boot from the USB driver, it hangs for 30-60 seconds and then gives me the "disk boot failure, insert system disk" error like it can't find any OS. Just for laughs, I disabled the RAID controller again and it booted fine. I'm having separate, unrelated issues burning a dvd with the ISO, so I would prefer to get this working.
1How does he slipstream the RAID drivers when first starting Windows, when it won't even boot the USB Windows installation disk? In order to ask for the drivers, Windows install has to boot. – kmarsh – 2010-04-15T20:55:10.690
He can boot Windows by changing the controller mode. Then he can enable the RAID drivers, then change the controller mode back, and reboot. – David Schwartz – 2011-10-30T23:57:46.963
