I have window 8 on C drive I would want to install linux on E drive how can I do that ?
Defragment your drive, download a linux distro and get it onto a cd/dvd/usb stick (burn the image to dvd or use unetbootin to make usb stick bootable). Boot up from that and pay attention to what the screens are saying. Any? (certainly most) modern linux distro is going to hold your hand through the install and resize your Windows partition and create new ones for linux to be installed to. Pick a big name distro and read the screens and you pretty much can't screw it up. (although as always, you are going to want to have a backup of your very important files just incase something goes horribly wrong)
Hi Kaushik, bit of a late reply but if you're still having problems check out this guide by Leeky. It's for an older Ubuntu distro, but the idea of how to install Linux, specifically Ubuntu, alongside Windows is the same.
