Ok, this is weird..I recieved a 40gb western digital hard drive that wouldnt boot. I used fdisk to get rid of partitions and put a new one on it. I reformatted it and put XP home on it, and that got it to work somewhat. When I turn the computer on, it goes through its mobo posts etc like normal, then it goes to a screen that says keyboard is not found. Then right after it says keyboard found press enter to continue. If you press enter, it goes to the flashing cursor in the top left and sits. But if you press Ctrl-Alt-Del at the keyboard found screen, it restarts and boots normally. The actual OS and everything else works fine. The only explanation i can think of for tthis is that the boot sector is bad, so it wont start the first time, but when you restart it also looks in the first sector where it boots from?
It doesnt hurt anything, just adds a little more time to startup. Ive never seen this before, so I was wondering why it was doing this.
