Just to make it clear from the start: I have absolutely no in depth knowledge of windows. I got this company computer with windows 7 on it that was in a domain. It starts up fine but I can't login because the computer is not connected to the domain anymore. My idea was to get the hard drive, put it in a external hdd interface and connect it to my laptop, recover the windows key with ProduKey (worked for me in the past) and just reinstall windows on the company pc. But when I try to connect the hdd it doesn't show up in the explorer and not even when I list the disks in diskpart. It just shows up in the diskmanager but it displays a storage capacity of 16TB (it's a 500gb hdd). Can anybody give me any advice on how to get the windows working on that machine?
