Is there anyway I can make this bootable as I have my dell hard Drive in it. And display went on dell on second hard drive Etc. It's far to old to sink any more money into it so I bought a new one with Windows 10 Home upgrade. I would prefer to have windows 7 pro licence on my new computer so I can upgrade to Windows 10 pro. Or do I have to buy an external hard drive to clone the Disk and go from there. It would be much easier if they would let you put in your Windows 7 pro licence but I don't know a lot, so there must be a reason as to why you can't do it.
