View Full Version : Unable to boot from USB drive after strictly following all instructions

Hi,

After reading and following all instructions I have attempted to run Ubuntu desktop edition 12.x from a 16GB USB drive. I downloaded the iso and the universal pen drive utility. I allocated the max 4GB storage on the drive with an apparent successful install. My system is both 32bit and 64bit compatible. When restarting the system, I used the F8 option to choose the USB drive as the start up device. The first few times I only got what appeared to be an icon of a hard drive and a person at the bottom of the screen. Eventually I was able to get to a progress bar which seemed to be loading. Just when I thought all was going to work, the screen turned into a massive black and white screen of non stop scrolling zeros and ones. Please note that I have also tried changing the USB drive to the start up drive in the bios with the same results. Any help and/or advice would be greatly appreciated.

Thank You,
Mark

Q? - If I were to install Ubuntu as a dual operating system on the same Hard hard drive with Windows 7, is there a risk of any existing malware on the windows 7 drive contaminating the Ubuntu installation?

Welcome to the Ubuntu Forums :-)

Several things might be causing your problems. It will be easier to give good advice, if you specify your computer

- Brand name and model
- CPU
- RAM (size)
- Graphics and wifi chips/cards

1. Have you checked with md5sum, that the download was good?

2. Have you tried another tool to make the USB install drive? Maybe you should start without persistence because it is easier. See this link

3. It might be the graphics card. Try with the boot option nomodeset and some other boot options too. See this link

A lot of people report problems when using Universal, try UNetbootin or Startup Disk Creator.
Sudodus, (the previous poster), also makes a foolproof installer called OBI for doing Full installs.

I have not heard of Ubuntu catching malware from Windows or anywhere else.
