How to make USB bootable Linux OS !! (Source

                                                                       Most of the popular Linux distributions these days offer live cd so that you can feel how their distribution feels before you can install it on your computer. If boot Linux using live CD the system takes ages to boot and applications installed feel sluggish as the optical drive offers lower data transfer rates. But if the same live cd is copied to a USB drive and made bootable then the system feels real fast as if you are booting from a hard disk drive.
There are several ways in which you can create bootable Linux drive, some of them requires lot of steps to be followed. In this post we see how we can create a bootable Linux USB drive from within Windows.


1. Windows XP or Windows Vista based host operating computer
2. USB Flash/Pen drive.
3. Get UNetbootin software from here.
4. A computer that is capable for booting from USB devices.

How to Create Bootable Linux USB Flash/Pen Drive

1. Download the version of Linux that you wish to install in USB drive. In this post we have taken Ubuntu 8.04.1 ISO file that we downloaded from Internet.
2. Open the UNetbootin utility and go to the second option called “Diskimage” and select ISO mode. Once these modes are selected then point the ISO file that you downloaded in step 1.
3. Make sure you that you have selected the correct USB drive of your choice where you want the Linux live CD to be copied. Warning: Make sure that you backup the data that is already existing in the USB drive as this software will erase that.
4. Once you hit the GO button the utility will start copying the necessary files to USB drive.
5. After the copying of the files is complete the utility will ask you to reboot. Now reboot your computer and boot from your USB drive.

How to make USB bootable windows OS ( source :

This guide works 100% for Vista & Windows 7 unlike most of the guides out there. I have seen many sites/blogs that have “Install Vista from USB guide” but either with incomplete steps or not working guide. I have also seen some guides that don’t’ use proper commands in this guide. After spending many hours I have come up with this 100% working guide.
Bootable USB drive
I just did this method on one of my friends machine and installed the new Windows 7 BETA. The main advantage is that by using USB drive you will be able to install Windows 7/Vista in just 15 minutes. You can also use this bootable USB drive on friend’s computer who doesn’t have a DVD optical drive.
The method is very simple and you can use without any hassles. Needless to say that your motherboard should support USB Boot feature to make use of the bootable USB drive.
*USB Flash Drive (Minimum 4GB)
*Windows 7 or Vista installation files.
Follow the below steps to create bootable Windows 7/Vista USB drive using which you can install Windows 7/Vista easily.
1. Plug-in your USB flash drive to USB port and move all the contents from USB drive to a safe location on your system.
2. Open Command Prompt with admin rights. Use any of the below methods to open Command Prompt with admin rights.
*Type cmd in Start menu search box and hit Ctrl+ Shift+ Enter.
*Go to Start menu > All programs > Accessories, right click on Command Prompt and select Run as administrator.
3. You need to know about the USB drive a little bit. Type in the following commands in the command prompt:
First type DISKPART and hit enter to see the below message.
Bootable USB Drive
Next type LIST DISK command and note down the Disk number (ex: Disk 1) of your USB flash drive. In the below screenshot my Flash Drive Disk no is Disk 1.
4. Next type all the below commands one by one. Here I assume that your disk drive no is “Disk 1”.If you have Disk 2 as your USB flash drive then use Disk 2.Refer the above step to confirm it.
So below are the commands you need to type and execute one by one:
(Format process may take few seconds)
Don’t close the command prompt as we need to execute one more command at the next step. Just minimize it.
Bootable USB Drive
5. Next insert your Windows7/Vista DVD into the optical drive and check the drive letter of the DVD drive. In this guide I will assume that your DVD drive letter is “D” and USB drive letter is “H” (open my computer to know about it).
6. Maximize the minimized Command Prompt in the 4th step.Type  the following command now:
D: CD BOOT and hit enter.Where “D” is your DVD drive letter.
CD BOOT and hit enter to see the below message.
7. Type another command given below to update the USB drive with BOOTMGR compatible code.
Where “H” is your USB drive letter. Once you enter the above command you will see the below message.
8. Copy your Windows 7/Vista DVD contents to the USB flash drive.
9. Your USB drive is ready to boot and install Windows 7/Vista. Only thing you need to change the boot priority at the BIOS to USB from the HDD or CD ROM drive. I won’t explain it as it’s just the matter the changing the boot priority or enabling the USB boot option in the BIOS.
Note: If you are not able to boot after following this guide means you haven’t set the BIOS priority to USB. If you got any problem in following this guide feel free to ask questions by leaving comment.
Update: If you find this guide difficult to follow, please use the easy-to-use guide to create a bootable USB to install Windows 7 using official tool.

Ubuntu TightVNC Server

This guide intends to show you how to build a headless server with tightvnc, such that you can remotely access the server’s gui using any vnc client.  I’m still working on it, so if you have any comments or questions, please feel free to let me know.
sudo apt-get install tightvncserver
Then create and edit: /etc/init.d/vncserver in your favorite text editor. Copy and base the contents between the ——, then modify the variables up top as necessary.
#!/bin/sh -e
# Provides: vncserver
# Required-Start: networking
# Default-Start: S
# Default-Stop: 0 6
# The Username:Group that will run VNC
export USER=”username”
# The display that VNC will use
# Color depth (between 8 and 32)
# The Desktop geometry to use.

# The name that the VNC Desktop will have.
OPTIONS=”-name ${NAME} -depth ${DEPTH} -geometry ${GEOMETRY} :${DISPLAY}”
. /lib/lsb/init-functions
case “$1″ in
log_action_begin_msg “Starting vncserver for user ‘${USER}’ on localhost:${DISPLAY}”
su ${USER} -c “/usr/bin/vncserver ${OPTIONS}”
log_action_begin_msg “Stoping vncserver for user ‘${USER}’ on localhost:${DISPLAY}”
su ${USER} -c “/usr/bin/vncserver -kill :${DISPLAY}”
echo “need to implement”
exit 0
Save the file and make sure the permissions are as follows:
-rwxr-xr-x 1 root root
Update your rc.d by running:
update-rc.d vncserver defaults
Reboot and you should be good to go.
