I have an old Intel Pentium w/ MMX 166mhz box and an unknown speed (maybe 300mhz or so) computer that i am trying to get Windows 2000 Advanced Server on. I installed it on another computer because it is much faster. When i bring the hd back over to the computer, it will boot fine and in win2k it has a screen that is black with a gray bar on the bottom that fills and it says Loading Windows. When it gets to this point it reboots, and it does this over and over again on both computers. Linux also did something similar. I dont have a floppy drive on the computer and they have each 64mb of memory. Why does this keep happening?
