Is Unetbootin capable of making any iso file bootable
 
1)It is a great experience to achieve what I got today. I had downloaded GParted iso file (135 MB size). Now to make a bootable usb of it, I used unetbootin and to surprise I succeded in entering Gparted application and modified my partitions.
Earlier I was in a notion that it is used only for installing Linux by making bootable usb,etc. so, can it be used for any iso?

2)As I had earlier installed OS, I had to specify where I want to install it. But in this case (point 1) where I made bootable usb of Gparted iso: when I booted my system by doing the appropriate BIOS set up, It didn't ask me where to install Gparted. Directly I entered the Gparted application. So, please clarify me what happened in this case. Did it install in USB drive only?

3) When I entered the gparted application, there I opened a terminal. When I entered command
Code:

shutdown -h now
it asked me for root password. Because while booting from usb, it nowhere asked me for root credentials. so what is root password.

It can be used for pretty much any Linux based ISO, with a few exceptions. It can be used for more than installtion discs: utility discs (like gparted) and live discs.

There is no install. the GParted ISO has only one purpose, to allow you to edit partitions.

Use sudo, as per GParted's website:

1.Yes as long as the iso is bootable.
2.It placed the iso on usb so that you can use it, similar to a bootcd.
3.If you want to exit gparted
Right-click on screen & select "Shutdown Menu"

BTW congrats on getting usb working thru unetbootin.

The Unetbootin site and other apps like universal installer tell you the tested iso's that are known to work. Generally they fall into three categories. One is live plus persistence, two is live only and three is won't work. I'd guess many of the newish live cd's can be made to work but some odd distro's won't ever work with unetbootin.


Most distro's could be made to be installed to a flash as if it were a real hard drive and bypass the unetbootin deal.

Some unique distros like LPS and Puppy and DSL have their own odd issues.

Can Gparted iso file that I downloaded be used to run inside windows like any other exe file we run inside windows.
Can the iso be made to run in Linux also?

Iso's are meant to be booted I don't believe that gparted will run in windows either, but you can install to a linux system.
I thought that you had success with unetbootin. I found a video for you about unetbootin.

The GParted ISO file contains a complete Linux operating system that automatically starts the GParted application. It is in no way comparable to executable files on Windows or Linux.

If gparted is running from a booted linux system it is the root password that you created at installation.
You can however use sudo if you setup sudo, but to edit sudo
you still need the root password.

The GParted live-medium (like most live-media) has no root-password set, if you want to do something as root you have to use the sudo command, like in
Code:

sudo fdisk -l
