Make a USB installation media from a Linux ISO

This is for those people who are going to migrate from Windows to Linux. It is better to use a USB flash drive for OS installations instead using a boot-able CD or DVD. Because it is faster and more reliable.And it is more flexible when you use it as a live system. So I am going to explain how to do it. Lets make a boot-able Linux USB installation media from a Windows system.

Requirements :
           1. A Working USB drive of 1GB or greater.
           2. Unetbootin : Free utility (Click to Download)
           3. A Linux/BSD Distribution ISO like Ubuntu
           4. Windows XP or later as your base.
Now gather all the items listed above then lets get started.

1.Install Unetbootin and open the utility. It will be looking as follows:

From the above window select the ISO disk image from your local drive where it is saved and select the target USB Drive which is going to convert to a boot-able one, leave all other options and click OK.If your USB does not  detected then reformat it to FAT32 and try.

2. It will take couple of minutes to copy the files and make it done .After that click on 'Restart Now' or 'Exit  according to your wisdom.Now your boot-able Linux USB is ready. You can make use of it.

Please Note : 
Sometimes there may be a boot device error and you will not be able to boot up from your USB boot-able drive. This is because your partition is not active .To Fix this error follow the steps below.

1. Open windows command line (for windows XP type cmd in run window and press enter ,For     Windows Vista or Later type cmd in start menu ,right click on it and select run as administrator and then OK )
2. Now type : 
             DISKPART .
3. In diskpart utility window type the following command:
             LIST DISK
4. The above command will list all the disks in your computer. Figure out your USB drive number. I assume mine as 1. Now type :
             SELECT DISK 1
             SELECT PARTITION 1
5. To save all the operations and exit type the following commands.You are done.

To get started open up the  terminal and  :
  • Type df you can see the list of partitions with available free space listed.
  • Type df -a to get a detailed listing of free space. this Include in the listing file-systems that have a size of 0 blocks, which are omitted by default.
  • Type df -h to get a listing more optimized .Here size is listed in MBs .-h stands for human readable form .
To get the detailed syntax information use the command man df. This will list all the possibilities of the command.
