Many of my friends wanted to try Linux, but they were afraid about messing up the existing partitions on their hard drives. If you have a flash drive with atleast 1GB free space, here is a no risk program !

In my previous post about installing Linux on flash drive we discussed only about Ubuntu Linux. What if we want to try other flavors of Linux? Here comes UNetbootin. It’s a free software which could make your favorite Linux distribution to boot from a thumb drive.

You can either select an ISO image already downloaded or if you are having internet connection then can download Linux distro of your choice from the list of  distributions.

No need to format your thumb drive in ext2/ext3. It’s a great advantage, that you could still use files in thumb drive on Windows. UNetbootin copies all the necessary files and makes it bootable.

We need to change boot order in BIOS : First boot device –> USB HardDisk

UNetbootin is an open source project hosted at sourceforge.net

Requirements

• Microsoft Windows 2000/XP/Vista, or Linux. If you are having trouble with the Linux version, try the Windows version, it usually works better.
• A broadband internet connection to download the distribution’s .iso file (unless you’re using pre-downloaded files)

Download UNetbootin for Linux

Download UNetbootin for Windows.

You can improve the performance of your existing Internet connection by applying these tweaks:

1 – Tweak Win XP TCP connection limit http://tinyurl.com/4bccwp
2 – Install cFos Traffic Shaping software
3 – Use OpenDNS, usually faster than ISP’s DNS http://tinyurl.com/ns48wa

Nowadays there are so many free DNS providers like the OpenDNS we discussed in the previous post

The best DNS server at one place may not be performing well at your region. It’s easy to check for the faster one for your connection. If you are on

• Windows, go to command prompt(Start->Run>type “cmd” without quotes)
• Linux users fire up a terminal

 

and issue this command

ping <DNS server address> eg: ping 208.67.220.220 (Open DNS)

The DNS address with less Round Trip Average(RTA) is the best for you.

For example:

With OpenDNS

C:\Documents and Settings\Vipin George>ping 208.67.220.220

Pinging 208.67.220.220 with 32 bytes of data:

Reply from 208.67.220.220: bytes=32 time=331ms TTL=43
Reply from 208.67.220.220: bytes=32 time=330ms TTL=43
Reply from 208.67.220.220: bytes=32 time=331ms TTL=43
Reply from 208.67.220.220: bytes=32 time=334ms TTL=43

Ping statistics for 208.67.220.220:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 330ms, Maximum = 334ms, Average = 331ms

With DNSAdvantage

C:\Documents and Settings\Vipin George>ping 156.154.70.1

Pinging 156.154.70.1 with 32 bytes of data:

Reply from 156.154.70.1: bytes=32 time=247ms TTL=48
Reply from 156.154.70.1: bytes=32 time=249ms TTL=48
Reply from 156.154.70.1: bytes=32 time=252ms TTL=48
Reply from 156.154.70.1: bytes=32 time=250ms TTL=48

Ping statistics for 156.154.70.1:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 247ms, Maximum = 252ms, Average = 249ms

Here DNSAdvantage is the winner. It may vary at your place depending on ISP, traffic etc.
