Hi , I have finished building my PC and I have an Ssd and an HDD. Windows 7 64 bit is installed on the ssd and I want to now use one of my 500 gb hdd's for games and other stuff.

I have plugged in the HDD with sata,all normal. But when I go to boot up it comes up with the "American Megatrends" screen. I know that this means that it is using the HDD to try and start but I don't no how to fix it. Any ideas? :)  thanks.

As rgd1101 stated, set bios boot priority to the SSD.

Question, when you did the initial windows install onto the SSD, You did have the HDD disconnected? If not your System partition (that very small 100->400 mb partition) will be on the HDD, not the SSD.

Err, American Megatrends Inc is the BIOS manufacturer. When a computer powers on, it reads a program from the bootrom. This is called the BIOS or Basic Input Output System. The bios is programmed with the necessary pieces of information in order to control/signal the hardware components and some various configuration items, like boot devices. Whether you are booting from an SSD or HDD is configuration within the BIOS settings (or UEFI, which is a new generation of the same thing). But it still comes down to the fact that the BIOS will always run before reading the configuration to determine the boot device (although these days it is a boot device order of preference), which in turn will then pass control to the boot device, which should be configured to be your SSD if you have set up the priority order correctly before installing Windows (some bios's will only allow you to choose a single HDD for a boot device, and you may have to do this in a different setting to the priority order).

The boot priority order needs to be configured before installing Windows, as Windows will need to install the boot loader onto the boot device (the actual installation files can be anywhere, the boot loader goes on the boot device - generally you want them all on the same device so your computer is not dependant on having two disks installed in order to startup).

Anyway, it will always startup with "American Megatrends", because the BIOS is the first thing that loads on the computer - this can easily be proven by unplugging all SSD's, HDD's and powering on the computer.

^ 100 % correct on Bios display.

Only disagreement is "The boot priority order needs to be configured before installing Windows" This can be done, often is as in many cases the first boot device is the CD/DVD drive, after windows Installation.

It has already prioritized the ssd and it works if I unplug the HDD.

What is not working when the HDD is plugged in?

What kind of HDD is it? A USB device or is it internal?

Edit: Got confused with another post so removed some stuff.

It is an internal HDD and the problem is that when it is plugged in, the system goes straight to the page entitled 'American Megatrends'- like a new pc with no OS would. On this screen, it shows and recognises that there is an ssd and an hdd.

Presumably the American Megatrends screen shows the words ASUS EFI BIOS Utility at the top. If not, then you are still only in POST (Power On Self Test).

If you are only in POST, and it doesn't progress and there is no message for F2 for setup/Del for setup etc., then the plugging in of the HDD sounds like it is causing a failure in the POST somewhere. This could be caused by you HDD being dead, causing a short, or maybe having a jumper set on it in an incorrect position.

Which SATA sockets are you plugging the HDD into. And which one is the SSD plugged into.


I assume that the HDD is a SATA drive and not a PATA with an adapter.

Assume that the system works without the HDD.

Also, what PSU do you have, and what rating is it, how old is it. What other components do you have.



If it is throwing you into the BIOS screen directly, so you can change the settings for the bios, then that would be the time to select the SSD as the boot drive over the HDD.

If you aren't able to do this, then
