reboot and select proper boot device asus windows 7

I cannot use the computer in this state: "reboot and select proper boot device"
Asus windows 7,
this is the message I get when starting my computer. It has never happened before. I am presently in the BIOS advanced mode:

Bootup Numlock State = On
POST delay time = 3 sec
Wait For 'F1' If Error
Fast Boot = Enabled
USB Support = Partial In
Network Stack Driver Support = Disabled
Option ROM Messages = Force BIOS
Setup Mode = EZ Mode
Next boot after AC Power Loss = Normal Boot



My specs are under avatar

Thanks for the reply mellon, unfortunately that does not seem to work. My OS is on the ssd which is the primary boot, but it doesn't fix the problem.

Is your SSD registering in the BIOS under Storage devices, or boot order? If not test it using the manufacturer's diagnostics and Disk Check.

If so assure the 100mb System Reserved partition (preferred if you have it) or C is Partition Marked Active then run Startup Repair - Run up to 3 Separate Times.

If this fails reset the BIOS to defaults and try again.

Disable Fast Boot to read all messages during post.

All other steps available are here for Troubleshooting Windows 7 Failure to Start including using Paritition Wizard boot CD to mark Active and Rebuild MBR. If you do these then post back a camera snap of the PW drive map and listings as this will tell us a lot. Then do those steps with PW, if it doesn't start do the 3 repairs again.

Hi Greg, thank you for the reply. I can only get to the BIOS on my desktop. The OS is not recognized by the motherboard. So-far I have reset the defaults, did not work. In Hard Drive BBS Priorities (bootorder) the ssd is first boot and the hhd is second. However in Boot Option Priorities option #1 is the ssd and option #2 is P3: TSSTcorp CDDUDW SH-222BB. I do not know what that is.
Windows 7 came preloaded on the machine. I have the disk and ran it. I couldn't use the keyboard, it won't work. I have a Wacom Intuoso Tablet and tried that with its stylus. That way I could use the cursor but not the keyboard. I ran the repair 3x. There is also an option to run a command prompt, but as the keyboard won't work I couldn't use that either.
When you say to run the repair 3 separate times, do you mean to reboot between running it?
Is there somewhere in the BIOS where I can see the OS?

The BIOS only shows hardware, not software. It has no idea of what operating system is installed. It only does what you tell it to do. When you set the boot drive the BIOS initializes it and looks for a boot loader to run. If it can't find one it then goes to the next device set in the BIOS boot device order. If it can't find a bootable device you get the error you mentioned. Option #2 P3: TSSTcorp CDDUDW SH-222BB is likely your optical drive. Your CD or DVD drive. If your keyboard is wireless try a wired USB keyboard. On my two ASUS motherboards, the quick boot option menu is accessed by pressing F8 during the POST. Its a one time quick access menu to set the boot device for that boot. Are you having any other issues like the date and time in the BIOS being messed up. It doesn't happen very often but sometimes a dead BIOS/CMOS battery can cause weird things to happen. You can boot up without it, the BIOS just won't retain any settings when you shut down again. If you don't have a spare you could just remove it for testing purposes, and then put it back in. If try it keep track of the polarity when you take it out and be careful of static discharge.

Thanks for that info Alpha, presently it does not recognize the disk either, I'll go back and try to set it to dvd/cd and hope I can at least try again.

Normally if the CD or DVD is bootable you'll see a "Press any key to boot from the DVD" which times out automatically. It couldn't hurt to power down and check all your SATA cables and Power cables to your drives to make sure they are all firmly connected. Vibration and heat cycles can sometimes work them loos in their connectors. Just to confirm, the SATA drive is listed correctly in the BIOS boot options menu?

I just ran the repair and the result is:
root cause found, Partition table is corrupt on disk \Device\Harddisk 1
Repair action: Partition table repair
Result: Failed. Error code= 0x490

I don't know what that means and Google wasn't much help. I have to call it a night for now, I'll have another go at it tomorrow. My back is acting up and I have to take a break from my PC for a bit.
