how do you install linux on windows because my friend wants linux on window:confused: :scratch: :Pengy: :newbie:

I recommend a live CD/DVD instead.

live cd of

Depending on computer specs and personal needs it is your choice.
Knoppix is a great live CD/DVD, Damn Small Linux is a great bare essential live CD, Ubuntu is a great Live/Install CD. There are lots of others. Check Distrowatch and search for live CD/DVD if you are undecided.

how do you instal linux not on windows

Any actual installation of Linux on a computer that is currently running only Windows involves resizing the single partition to allow Linux to be installed onto it's own partition. This allows booting into either Windows or Linux.

The advantage of a Live CD/DVD is that installation is not needed. The live CD/DVD just boots into linux and runs from RAM with no change to the hard drive. This is great for checking Linux out but has the downside of not saving configurations by default and being somewhat sluggish since the CD/DVD must be accessed rather than the hard drive.

There were many options to adding Linux to FAT partitions but current NTFS partitions are a different story. I am sure M$ did not do this on purpose. :)

Do you mean with a Virtual machine?
The most common method is dual-boot, but the virtual machine approach is getting more popular.

Please read my article on Getting started (link below). I think this will help you with several of your recent questions.

You can try the Virtual machine by Microsoft.

There is a pretty good virtual machine called vmware http://www.vmware.com/
not to hard to use and you can install any OS and run it from within windows.. I liked it more than a live CD/DVD only because it did not have to access the CD/DVD every time i changed something thus making it run a little smoother than the Live distro's

Try CoLinux (http://www.colinux.org). I know ubuntu and gentoo can run with colinux. Check out the colinux wiki for more info on how to install use different disto with it: http://colinux.wikia.com/wiki/Linux_Distributions. One distro is specifically tailored using colinux, so you might want to try that out: http://www.topologilinux.com/ because it doesn't require a dedicated partition for it. :)

i suggest VMware, it is a pretty good program

well what do i download from http://www.vmware.com/download/ goto this link

VMware Player at the bottom of the screen. Given the choice, I would choose virtualbox instead, http://www.virtualbox.org/, because it is faster.

VMware Server is also free

My laptop has a Pentium M 2.13GHz processor and 1GB DDR2SD ram, I just finished spending many hours installing the original Windows XP Media Center as a guest OS inside of Debian testing. Beryl in Debian was choppy and Windows takes like three times longer to boot up and power down compared to when it is in a dual boot scenario in it's own partition. And the hard drive in my laptop never stopped grinding as it was working all the time. I find it was allot faster to power down Debian and boot up Windows in a dual boot scenario than it is to have them both running together if I needed to run a Windows specific task. I love my Debian's power and speed and need it for certain forensics tasks, I could not accept the penalties associated with a virtual configuration in either OS and wiped out the virtual Debian, reloaded an image of it without vmware and reloaded an image of Windows in it's own partition as a dual boot. Much much better, I don't need Windows that bad.
All I can say, is if you want the virtual method of having more than one system, you better have lot's of ram memory. For now, I still have Debian as a virtual host on my desktop with Vista & Windows Media as guests. The desktop has a Pentium 4 650 (3.4GHz), it also has been penalized severely. I'm pretty sure that one also will go back to a non-virtual scenario. I left the tardy computer environment a couple years back, going virtual brought me back to those dreaded days, I prefer to see the tires spin the second the pedal hits the floor.
