Hi, I have taken a hard drive out of one of my other PCs to use in a new one i built. It had Windows 10 installed already so it should have booted up fine. But it just showed the windows 10 logo and did nothing. No spinning circle or anything. So i though i would need to reinstall windows so i used a bootable iso i had used previulsy and it does the same thing. It wont even reach install options, it just sticks at the windows logo screen with NO spinning circle. I have tried Davriks Boot and Nuke but that does the same thing. I cant even reinstall windows which is very strange. Any help is appreciated. The PC specs are: Acer ASpire M5640 (modified with a core 2 quad q8200, 4gb ram and a 160gb hdd)
