Hi:
When Windows 7 start up. The first thing it does; is to send out a request to your Drive Manager and ask Hey buddy what drives do we have and the drive manager tell it, this what we got Drive C: Drive D : and Drive A ( if got that ( a Floppy disk drive) ). when you connected it to the USB port The USB bus should send a Request to Windows and say we got a New piece of Hardware and windows 7 should send a request to the New hardware asking what are you? and if your new drive has a plug and load program - it send a request to Windows 7 saying I'm a New disk drive and I want to load my drivers ( the interfacing program that enable windows 7 and the New drive to talk to each other) into you and please put my Id in your Disk Manager So I will recognize via my coded input code. And Windows will either say "go ahead" or No, because I don't recognize you HP code however sometime Windows 7 will recognize it - only after you restarted your again with the USB still plug in to it in both your drive and it. than it will recognize your external hard drive. to initialize the drive program
I hope this helps

how do I install Windows 8 on my external hard drive?
Christophe
I took all the steps necessary up to the point where I choose where to install windows but it wouldn't let me select the external hard drive because it's connected via USB... why won't it let me and/or is there a way around this because that's the only way I can connect the hard drive
Answer
Ifan operating system is already on the computer, make sure the drivers are correctly installed; and try installing when the OS is on. Windows should then detect the drive as if you have booted from a DVD, it might not detect
