problems booting from vista setup disc

[powpowmeow]

Have a brand new Acer laptop. It comes with Vista Home Basic 32 bit installed. I want to install another version of Vista over it. Have a setup DVD. I set the BIOS to boot from the DVD drive, i press the button to boot from disc, and the computer stays in a permanent loop with the black screen that says "(C) Microsoft" and the small status bar moving left to right. I can leave it there for an hour and it will do nothing. I have tried the official Vista recovery disc from Microsoft, and the exact same thing happens. I have tried using my XP Professional setup CD instead, and after about 5 minutes of loading drivers to run the XP setup, I get the bluescreen. I also tried a friends Vista setup DVD which is a different version that the one I am trying to install, and I got the same problem - computer was hanging on the startup screen with the status bar scrolling left to right eternally.

Is this a bad laptop or what?

Model Acer Aspire 5515. Optionally, you can do a restore from the X drive which will copy all the Vista Home Basic files from a 10 GB partition back to the main partition on the hard drive. I want a different version of Vista so obviously this will not help me.

Thanks all for you help!

Boot the PC normally and then insert the Vista disc. When it starts up it should open a box with the install options.

Boot the PC normally. After it has fully booted, insert the new disc.
