My answer is slightly long winded, but thorough and based on an expensive disappointment at the hands of Vista.
This is an ideal opportunity to try out the new Linux Ubuntu 7.10, the graphics and effects are far superior to Vista see link below :

Ubuntu is free as it is open source, the download link is :
http://www.ubuntu.com/
Once you have downloaded Ubuntu 7.10, you will have an ISO image file. You will then need to create a bootable disc of the file.
This can be achieved by using Nero Burning ROM if you have it or MagicISO a free trial of which is available for download :

Once you have created the bootable disc, we are going to call it the LIVE CD.
Start your PC from the Ubuntu live CD, select start or install when prompted, once the Ubuntu desktop has appeared in the top left hand corner there is an option to install, double click and the installation screen will appear.
Once Ubuntu has asked you about regional settings etc. it will then take you into the partitioning table, if you select the default setting which is on the top, Ubuntu will then automatically sort the space it needs and install its own Grub bootloader.
I am so taken with Ubuntu 7.10, I have ditched windows altogether and I am now running Ubuntu as my primary operating system.
You can run quite a number of windows applications on Ubuntu using WINE, a piece of software that emulates windows. For details of this visit :

Ubuntu 7.10 is also incredibly easy to use and has online support second to none :
