When I turn on my computer a black screen comes up and then some writing comes up saying... Intel UNDI, PXE-2.0 (build 083) Copyright (C) 1997-2000 Intel Corporation For Atheros PCIE Ethernet Controller v2.0.2.2(03/31/10) Check Cable Connection! PXE-M0F: Exiting Intel PXE ROM. No bootable device -- insert boot disk and press any key ......So what does it need me to do?

That message is because the laptop is trying to boot through the network. You have to change the boot order in the BIOS, and put on first place the hard drive. Press the F2 key just before turning on the laptop. You should go to the bios program. On the bios, search for the Boot tab-move with the directional keys- you should see something like this: http://slackworld.berlios.de/2007/images_vmware/vm-bios-cdrom-boot.png. Press F5/F6 to move the hard drive on top. Then press F10 key, hit "Y" and then "enter". The laptop will reboot and it should boot through the hard drive-on which you have windows. If with hard drive on top, you still get that messsage, you will have to reinstall windows-it means that the files in the hard drive are corrupted- or replace the hard drive.
