How to install a linux os like ubuntu,red hat and need to have windows os also

Can I ask why you want Linux. (class purposes, personal purposes, experiment etc.. )

Have you ever used these OS'?

If not the more logical way is to install them on a virtual PC. This way if you're not satisfied they're a lot easier to get off your PC. You can install Virtual PC 2007 from Microsoft (for free) and then simply put the disc in and create your Virtual Machine and it will bring up the OS in a new window. It's like having to PC's sharing one screen. I am unure if you've looked into this at all but it seems more logical for someone who has never used it before!

Let me know if this seems like the right path or if you'd rather do a dual-boot!

If you download and burn the Ubuntu .iso to a CD and boot from that CD then the installation routine will take care of making sure that you keep your Windows and have a Linux partition. It will install a boot manager (in this case GRUB) that appears on boot up and ask you which OS do you want top boot to.

Of course you do not need any OS to be already installed before installing Linux, as long as you can boot to the CD you can just use Linux as your only OS.

My turn for a different idea.
While both the above are excellent ideas, how about this..

If you are simply wanting to use Linux for the experience rather than an ongoing biases, how about booting to a Live CD.

Ubuntu does this well.
Basically this doesn't install anything to your hard drive, but runs the OS from CD.
So you get the experience without worrying about installation..

As a continuation of this you can also install some linux distros on to Flash drives, which might be useful for you.

That's probably the best idea because in that case you're not installing anything!

I didn't even think about it, but yes opensuse linux is another good live CD distributor as well as Ubuntu. Your options for Linux are endless and all have their pros and cons... I like some others dislike and I dislike some that others love. It's all personal preference and you'll discover you're liking when playing around with them!

Good Advice CurlyBen

I have been using ubuntu in my coll for 2years bt I didn't installed in my home... but I want to work with python and qtk programs...
Live cd not be much good to work with since I need to save the programs...

I need to have windows as well the linux os


Multipartitionig the disk is what I fell is critical in this

And more over comparing to ms it is having some cons to work with in xl,spreadsheets etc so I need the both os to be in my system

If that's the case then the first two responses are what you're looking at. You can set this LInux OS up virtually, you can still store all the programs and files you want or you can setup a dual boot. If it's something more permanent than I would suggest dual-boot. But I am a big VPC guy so I would say try either or!

Let us know what you think! Ask Q's if you need to, that's why we're here!
