I checked the checksum and confirmed that my download was correct.
Then, I used Nero to burn the image on a DVD-RW since I did not want to waste a DVD-R on it.
On my first attempt to install, the process took a very long time. I backed up my data and wiped out the hard drive. Then, attempted the install again. This time, everything went smoothly.
The installation takes about 14GB! So, you need a large partition for it compared to what you need for XP.
