The time and effort to make a bootable Linux USB flash drive is certainly justified.

#WHAT IS PERSISTENCE IN UNIVERSAL USB INSTALLER WINDOWS#

I'm not a big Linux user, but anyone running Windows should get in the habit of using it, along with Firefox, for online banking. The drive is advertised as being relatively fast (I haven't tested this in detail and the vendor does not offer much in terms of hard numbers to document the speed) and Ubuntu booted and ran fast enough to satisfy most people.

It came pre-formatted with the necessary FAT32 file system. The flash drive I used was a Patriot Xporter XT that was recently purchased for $13. I did this testing because I've had more than one copy of Linux go bad on me after installing bug fixes. But, a later test of this same procedure didn't go as well, there were a handful of applications that failed to startup. One time after renaming the casper-rw file back to its original name, a subsequent reboot was fine, the system changes I had made re-appeared. But, if it was booted with an external USB mouse present, all was well.

It also failed to recognize an external USB mouse inserted after the system had booted. However, on three different laptop computers, this newly reverted copy of Ubuntu failed to recognize the internal mouse hardware. Sure enough, Ubuntu booted in a virgin state. Changes made to the system persisted across reboots and switching computers.Īs an experiment, I renamed the casper-rw file, while in Windows, and rebooted to Ubuntu. Afterwords, Ubuntu 10.10 booted just fine on both a ThinkPad laptop and a Samsung netbook. I opted to create a 2GB casper-rw file and the installation proceeded without a hitch. How a 4GB file would fit on my 4GB flash drive alongside the OS is also not explained. What 'casper' is, is not explained, but it appears to be the work area where system changes are saved. Mostly, it lists the pros/cons without specifically explaining things.įor example, I was offered a choice of creating a 4GB casper-rw file. There is documentation for persistence, but you know you're in trouble when it starts by defining the word, as if 6-year-olds were interested in installing Linux. This is not clearly stated but seemed to be true in my testing. If you disable persistence, then your USB flash drive will, like a CD, be exactly the same every time it's booted. The last step, persistence, is poorly documented.

When I ran it, the only drive letter I could use was, in fact, the correct one. Next, you point it to the drive letter with the USB flash drive.

In my case, it automatically found the ISO file.

Then you point the software to the already downloaded ISO file.

The first step to running the Universal USB Installer is to chose the Linux distribution you want to install onto the flash drive from the list of supported distributions.

You should download the ISO file for your preferred Linux distribution ahead of time.Ubuntu 10.10 took up 692 megabytes on my flash drive. This is certainly possible, my experience has been that having a few extra folders does not interfere with Ubuntu running from the flash drive. Any more seems wasteful, unless you want to store other files on the drive. The flash drive should be at least two gigabytes.Files on the flash drive before starting the installation, are not wiped out when Linux is installed.The installer program used to be able to format the drive for you, but this feature has been removed. The flash drive needs to be formatted with the FAT32 file system.The Universal USB Installer runs under Windows XP, Vista and 7.You are much better off reading about the Universal USB Installer from the source. The bad news is that Canonical's documentation is far from complete. I've used it in the past, from within Windows, with good success. Thankfully, Canonical, the company behind Ubuntu, now seems to have endorsed the Universal USB Linux Installer available at. This was documented poorly and failed as often as it succeeded. In the old days, I used to create a CD, boot to it and then use the included Startup Disk Creator from within Ubuntu to create a bootable copy on a USB flash drive. I was pleasantly surprised that the Ubuntu download page now includes instructions for installing the system onto a USB flash from Windows, OS X and, of course, Ubuntu. My USB flash drive with Linux was getting a bit old, so I set out to create a new one with the latest version (10.10) of Ubuntu.
