Help installing windows to free space on harddrive

[alecwlkns]

I am having trouble installing Windows to my external harddrive. I have more than enough space (~350GB) free, but the Windows 7 installer DVD will not let me install to this space.
I need to install to this harddrive because the HDD that came with the computer is dead. Can you help me?

Is it formatted ntfs?
Most portable drives come formatted fat32.
Windows 7 will not work with fat32
anyhow instead of running you through all the possible reasons it may be best just to follow this.

following that should eliminate the majority of things that would be causing the problem.

I don't believe you can install Windows to an external hard drive.

oh wait are we trying to do this while it's still in a usb enclosure? bad idea would be horribly slow anyway.

I thought he was saying he had a external drive that he was using as a replacement.

...which would be the way to go here.
Remove it from the portable enclosure and put it in the computer.
