I assembled a new computer. The motherboard is Asus M4A89GTD. I connected an external USB DVD drive to a USB port and an Intel SSD drive to Sata port 1. I am trying to install Windows 7 from the DVD drive. In the BIOS I have boot sequence as USB drive then the SSD. The BIOS recognizes my USB drive and it displays the model name in the device list.
When the system boots I get a message "Reboot and select proper boot device or insert boot media...". I know the dvd disk & drive work because I used them on another system to install Windows. I tried another boot disk but I get the same message. I also made the USB drive the only boot drive.
Somehow I think the BIOS is ignoring the dvd drive and the HD is taking over first. I think I read that the HD needs to be on a slave SATA drive? port 5 or 6? I will try these, meanwhile any suggestions? ACPI setting?
Did you go into the BIOS and ensure that you have enabled USB support for booting -- even though it is a DVD\CD drive to the BIOS it will be a USB device so in the boot options you need to have USB device in the list of boot devices.
