Also, did you completely wipe the drive or did you just upgrade over the XP installation. What shoud I do to prep it? I've never wiped a laptop before. Is there any proprietary Dell software I will have to reinstall? Or do I just need to install the necessary drivers?
1. You will have to do a clean install (or custom install as Windows 7 calls it). It is not possible to upgrade install from XP.
2. Set your DVD drive as the First Boot Drive or Device in the laptop's BIOS. Put in the install DVD and reboot. You'll see a prompt to "Press any key to boot from CD/DVD drive". Do that within 5 seconds or you'll have to start over and reboot.
3. Once the install begins you'll get to a screen showing the hard drive and any partitions on it. Go ahead and delete all the partitions using the "Advanced" option in the window field below. Then create a new partition(s).
The partition for the OS install should be about 48-64 GB in size, then the remainder of the hard drive a separate partition for miscellaneous files and such. Then proceed installing the Windows 7 OS to the first partition you created.
4. You really don't need any DELL drivers or software, unless you want them. Just be sure to install the latest drivers for the main chipset, graphics media accelerator, sound, wireless networking, etc.
Get the drivers from the chipset makers websites, usually more up-to-date and compatible with Windows 7.
