Windows 7: Windows Boot manager does not find the boot drive

In BIOS can you set the SSD as the first boot device ?
I have Legacy BIOS, not UEFI, so my choices are different than yours.

Now Christoffer mate if you have the OS on a SSD then that disk 0 is indeed a very large one so what are disks 1 2 3?? spinners.

I am asking because Windows installs as I am sure you know to a drive it designates as C: drive.
, and most folks install a small SSD as the boot drive to save money and keep larger drives for data.

I would like to see a pic of the BIOS components and also the boot order screen.

Also just what is on those external drives??

I would advise you to connect your external HDD only after your PC Completes booting .

Thanks for the tips. However, I cannot switch to legacy booting, since the BIOS does not have that option. I need to be able to reboot remotely, which means I need to be able to boot with the external drives connected.

Regarding the drive setup. It is a computer used for scientific processing of huge uncompressed video files, hence the big disks.

Odd thing. If I turn off the USB legacy support in the BIOS the computer boots correctly even with the external drives connected.

Hi, I installed Windows 7 in UEFI mode to an SDD and I figured it would be easy to take my old drive which also had Windows 7 installed, hook it up to a SATA port, and copy over the files that I wanted. In my BIOS interface I can select the SSD drive to boot from, or "Windows Boot Manager"....
