Uninstalling windows 7

[Wolverhampton]

I don't think you have to change the boot loader? as Vista and Seven use the same one?

I tried deleting the files but it wont delete some, then I thought of formating the partition, but it said some of the files were in use?

What should I do?

Delete the partition in partition manager. (in vista right click computer>manager>disk management)

Or if you don't want to loose the partition yes you could format it and you would loose everything on that partition.

Just make sure you don't format/delete the partition that your MAIN OS is on.
