If it boots it'll error out. No drivers on the old drive for the new machine.
You can't just move a drive and expect it to work.
I am wondering if I can take the HDD out of my old emachine C2825 120gb and put it in my Compaq presario S4020WM. Will be compatible? Is it fairly easy to do? I am upgrading the emachine and the presario will be my kids to use for internet mostly.
Thank you for any assistance
