I was using windows os from a long time and just for an experience I am trying to use Linux os, as I am new to Linux I am fining difficult to create partition of my hard disk. If you are using Linux please help me to create partition.

Hello,

Have a look at man pages for fdisk, cfdisk, parted, gparted. And please remove the advertising in your signature, it's against the LQ Rules to which you agreed when signing up.

Kind regards,

just install gparted and simply edit your HDD partitions easily in GUI

If you have Vista or Windows 7 then use the built in tools to re-size partitions and create them in windows.

When you install then you select the new partitions. Be careful. Dual boots tend to mess up newbies.

If you want you can install to a usb flash or external usb hard drive. Remove power to internal hard drive before you attempt to be sure no data is written to that drive.

If you want you can usually do well with a free virtual machine. Most run fine on a newish system. It is the most safe way to run both at the same time at or near native speeds.
