It installs linux into a windows drive has an image file, so there is no need to partition the harddrive and no windows files are touched!
Of course file access is a bit slower than with a dedicated partition, but it's not very noticeable.
If you don't have the iso image it downloads the latest Ubunto for you and installs from that.
I do advice downloading the ubunto 32bit iso image first and placing it in the same directory of the wubi executable, because if you have a 64bit processor wubi will download ubuntu64 8.10 which has too many faults and bugs and Purebasic doesn't work on it.
(i've given up after 4 hours of downloads - package manager is broken in 64bit version and GTK2 just refuses to work
)( http://www.ubuntu.com/GetUbuntu/download )
To force a 32bit install run wubi.exe --32bit .
After installing you can access windows or ubuntu on windows boot startup !
If you don't like it, reboot into windows, go to the control panel and just press uninstall

I'm posting this from a fresh ubuntu32 8.10 install using wubi, took me just 10 minutes to install it, and purebasic took 5.
