For a proper clean install, you need to frormat the partition first.
You can do it during installation.
When you get to screen asking where you want to install 7 , select Drive Options( advanced) , the next screen allows you to repartition, delete, format, as you wish.
If you simply format the partition , then install 7 - you won't get the Windows.old folder.
However, that will also remove the Active flag ( if present).
Unless you have another Active partition - you will get the 100mb "system" partition.
As Tews says, easiest is to use 3rd party bootable partition manager - Boot the cd, delete the existing partitions - create new one(s) first - mark the intended 7 partition Active.
Then Boot 7 dvd and install direct onto that partition.

My pc is choc-a-block full of rubbish and I want it all gone without having to go through deleting it all manually..I've been able to wipe everything with previous windows installs so I can't understand why it doesn't work with Windows7.
Also, I have 2 partitions on my hard drive (the other has Linux on it)...I'd like to go back to just having the one & installing windows7 over everything...does anyone know how I can do this...pleeeeeeease???
forgot to mention...I'm not very tech savvy so please make any helpful hints as simple as possible. lol Thank you
