Reboot and Select proper Boot Device or Inser

Specs: Windows 7
I am building a new system. Today I put everything together and popped my windows 7 dvd into the drive and fired it up. I got a black screen with the message "Reboot and Select proper Boot Device or Insert Boot Media in selected Boot device and press a key"

I rebooted, same thing. Opened BIOS and checked devices. It sees the DVD drive and hard drive. Reset the boot sequence to DVD first. Restart and get the same message. Switched out the windows 7 disc for vista, same message. So I loaded the Windows 7 install files to a flash drive and hooked it up, changed boot sequence to usb, but get the same error. I have tried switching out the cables and made sure everything is connected well, still the same message.

Anyone have any idea what's up? Faulty motherboard maybe?

Without any additional hardware specs I can only guess at your problem but I would guess that you have selections in the BIOS set incorrectly. Specifically, SATA drive settings.

System Specs:
Asus M4N68T-M AM3
AMD Athlon II X2 250 AM3 3.0Ghz
Kingston 2Gb (2x1) DDR3 1333
Western Digital Caviar Black 500Gb Sata 32mb

I'm leaning towards a motherboard issue. On a whim I decided to pop in the recovery DVD for my laptop to see what would happen. Low and behold it started to load windows and then expectedly said "system does not match recovery specs." So I can be pretty assured everything is functioning fine, except for whatever reason the motherboard isn't recognizing the windows install DVD as bootable.

Well, I'm stumped. I've tried every possible configuration of SATA settings, tried switching out the motherboard with a replacement, still no luck. As it stands now I have 500 dollars worth of useless, non-refundable computer parts.

Is your optical drive ATA or SATA?

It appears to me that the system is not finding the hard drive. Look at the settings in 2.3.3 & 2.3.4 to see how to configure the drives. There are three choices for SATA devices. Disabled/ SATA 1,2/ SATA 1,2,3,4. Use SATA 1-4 and connect the hard drive to port #1 & SATA optical drive to prt #3.

There is a reference in the manual to look at the supplement to the manual concerning AHCI settings. That supplement is not included in the download manual so I can't view it.

Each SATA drive has a sub menu included, which must be configured. Most likely you will need to configure to use AHCI settings, but not sure of that.

Watch the POST screens at start up to verify all drives are being configured by the BIOS.

Boot order also has a submenu to select which device to boot to first. Tap F8 when the ASUS logo appears to get to that menu.

Disable any RAID settings.

Is Windows 7 DVD a "factory" DVD or a copy ?

If it's a copy
- it may not have been made properly (it's not bootable) , in which case the DVD will NOT boot the system on ANY computer. E.g. try to boot your laptop with it.
(The *.img file that makes the DVD bootable is not visible in Windows - if you use "Disk at Once" or similar in a burning program to copy the entire Windows disk, that hidden file is copied, but if you copy the contents of the Windows disk, it is NOT copied . You must have Windows Folder Options set to show all hidden files and folders before you make the copy. )

- the same applies to copying the contents of an actually bootable Windows 7 DVD to a flash drive - you MUST do that the right way, otherwise the USB drive will NOT be bootable. Try the USB drive that you copied the DVD contents to with another computer - I suspect it probably will NOT boot the system on other computers capable of booting from a USB drive either.
(The procedure for making a USB drive bootable is different.)

- a DVD-R burnable disk should read fine in any drive capable of reading from a DVD, but other types of burnable disks may NOT read properly in a drive it was not made in, and/or may NOT be found by the bios to be bootable in that case.

Are you SURE the drive you're inserting the DVD in can read DVDs ? If It can't, the bios will NOT find a bootable disk.

Is the optical drive you're inserting the Windows 7 DVD in new or used ?
If it's used, the laser lens may be "dirty"- if it is "dirty" that can prevent the disk from being detected as bootable. Use a laser lens cleaning CD in the drive. If you don't have one, get one, you should have one. Most places that sell CDs and DVDs have them, or even some "dollar" stores have them for a buck or two.

An optical drive does not necessarily have to be first in the Boot Order or similar settings in the bios Setup in order for you to be able to boot from a bootable optical disk - it just has to be before any hard drive.

You can have problems with a data cable that results in a bootable optical disk not being found bootable.

It is common to un-intentionally damage IDE data cables, especially while removing them - the 80 wire ones are more likely to be damaged. What usually happens is the cable is ripped at either edge and the wires there are either damaged or severed, often right at a connector or under it's cable clamp there, where it's hard to see - if a wire is severed but it's ends are touching, the connection is intermittant, rather than being reliable.
Another common thing is for the data cable to be separated from the connector contacts a bit after you have removed a cable - there should be no gap between the data cable and the connector - if there is press the cable against the connector to eliminate the gap.
80 wire data cables are also easily damaged at either edge if the cable is sharply creased at a fold in the cable.

Try another data cable if in doubt.

Check your SATA data cables. The connector on each end should "latch" into the socket on the drive and on the mboard, or on the drive controller card - it should not move when you merely brush your hand against it near the socket - if it does, mere vibration can cause a poor connection of it - use another SATA data cable that does "latch", or tape the connector in place.
(There is a slight projection or bump on one side of the outside of the connector that "latches" it into the socket - it's easily broken off or damaged)

The same thing applies for the SATA power connection.
