"reboot and select proper boot device...." with new HDD, but works with the old?

[yeezus]

"reboot and select proper boot device or insert boot media in selected boot device and press a key"
So, i got my new HDD (wd10ezex) and I have my old Hitachi HDD.
I particionated the new, a 100gb where i installed the windows, and the rest.
When i start the computer with both hdd in, everything is fine. But when i take of the old Hitachi, this problem appears. When i put it back, works fine again. I checked the BIOS, 1st boot device is my WD and everything, but without the old hdd it just won't boot...
Idk what's the problem, maybe i did something worng with windows install? It was a clean install, and everything was OK...
But there's one thing i noticed. The Hitachi has a 8mb partition, and the WD hasn't. Maybe that's something important which needed to boot? How to create that partition?
I don't want to reinstall windows again..
Thank's for any help

Did you take the old drive out or unhook it before you started the install on the new drive? If not this is the problem. Reinstall Windows to the new drive again, and make sure you unhook the old drive first.

Hey there, yeezus!

Did you unplug your old HDD when you fresh installed Windows on your new WD drive?
I think that the OS installation has encountered some sort of a confusion and installed the recovery partition on your old HDD instead of the new one. This usually happens when you have 2 drives plugged in.
If it's still fresh, I'd suggest to repeat the clean install again, but this time leave only your intended OS HDD plugged in the SATA ports.

Keep me posted! Hope this helped!

These guys are correct.

Yep, I had the old HDD plugged in while I was installing the windows on the new, you guys might be right, I'll reinstall again and see what happens.
Thanks!

I ran the windows repair tool from the install, and it's working fine!

I know we are right. Windows will only allow 1 boot sector to be installed on a system. If the old drive is hooked up, it will simply tie the boot sector of the old install to the new installation. You pull the old drive out later, you have no boot strap on the new install, so you get the no bootable device error.
