I just recently updated my bios from ver a07 to a11 and now my computer will not boot from the hard drive. I get a message saying "reboot and select proper boot device or insert boot media and continue" i dont have a boot disk just the windows 7 that came with the computer. Note that i have a alienware aurura r4 with 2 solid state hard drives. I can go into the alienware pre boot system assement from boot options and that shows my hard drives and boot path are working fine. In bios settings my sata mode is ahci and the boot mode is legacy and it shows my hard drive under the first boot option but uppon boot up it goes straight to the prev message.

Try loading Failsafe Defaults or BIOS Defaults (same thing, just different wording) in BIOS Setup.
Save to CMOS and exit/reboot.

"in bios settings my sata mode is ahci and the boot mode is legacy"
Are those the same settings as prior to updating the BIOS or don't you know?
It seems rather strange to me to have Boot Mode = Legacy, yet SATA Mode = AHCI
BIOS update may have changed one of those. Try SATA Mode = IDE (Leave Boot Mode alone).
If that doesn't work, change SATA Mode back to AHCI.
Then try instead changing Boot Mode.
Only change one setting at a time and don't forget to Save to CMOS and exit
If changing either of them makes no difference, set them back to what they were after the update, then start a new thread, explaining what you've tried already that didn't help.

ok so far i have tried sata mode ahci and raid. When i have it in raid i do get the hardrive boot up screen i had prev to the a11 update. How ever it now says in that screen that my raid volume status failed and that its not bootable. This screen also shows both hard drives 0 is non raid and 1 is member disk. Now for the boot mode i have tried both combos Raid+legacy wich gives me the "reboot and select proper boot device..." after the sata control screen. While Raid+ uefi mode i get a screen that says "internal hard disk drive not found to resolve this issue, try to reset the drive" again this is after the sata control screen. Now there is options in the intel rapid control sata menu to 1. Create volume 2. delete raid volume 3. reset disks to non-raid. IM not sure what any of those will do.

I can't suggest anything else or tell you which settings you need. BIOS is not my area of expertise beyond a few basic settings, and my board doesn't have UEFI anyway so I've never had to deal with that.
As I suggested, start a new thread so it shows as unanswered and a mobo expert will hopefully respond.

I'm in the same boat as dameius (was): upgraded BIOS from v A07 to A11 (also on an alienware box), and then couldn't boot (got the same error: "reboot and select proper boot device or insert boot media and continue"). Both my drives showed up in the BIOS/UEFI settings. These drives had worked under Windows 7 and the subsequent Windows 10 upgrade, but after the BIOS flash, the OS drive would not boot into Windows anymore. Fiddling with boot settings did nada.
Ultimately had to install a new hard disk and reinstall Windows 10 on it and start rebuilding everything from the two older drives. Now, I'm not sure if this is related, but Windows 10 then failed to see my two old hard disks when I readded them after the fresh install. They did not show up in either Device Manager or in Disk Management (lots of folks online have this issue). When I attached them via a SATA to USB cable as external drives, they worked just fine, but both were invisible to Windows 10 whenever installed internally. All online advice didn't work (chkdsk /f showed no problems, etc, etc, out of desperation, I even deleted the SATA AHCI Controller). I tried reformatting one when mounted externally, and Windows still couldn't discover it when mounted internally. What finally worked was to have all three disks internally installed, then reinstall windows. During the install, all three drives with their partitions were visible to the Windows installer, and for some reason, Windows 10 was then able to see them when the install was complete. Doesn't fill me with confidence for ever adding another internal drive in the future...
