Hi Ashesh, your blog looks nice :-)

Did you really write "the NTFS set as swap space"? If yes, then Linux is going to destroy your NTFS (Windows) partition little by little!!!

The swap partition should really be a separate partition because it gets overwritten dynamically by the Linux kernel when memory is scarce. I will advise you to create a small 1Gb partition for that purpose. You can slightly resize your main Linux partition using parted to create that space.

Use the mkswap command to "format" that new swap partition and modify /etc/fstab accordingly.

Anyway, welcome to the open source world! Have fun discovering the fantastic open source software that you have access to now. And don't forget to read the writings of Mr Eric Raymond!
