    Unable to boot from USB

    So there I just realized that my cd-rom isn't working properly so I decided to put the installation of Ubuntu on my USB pen. The pen is 8GB and I used UNetbootin to install the iso on the pen.

    When I restarted and entered BIOS to "Enable USB Boot" I couldn't find it. After long search it seems as I cannot boot from my USB.

    First Boot Options are
    - Hard Disk
    - CD - ROM
    - Lan Legacy
    - USB-FDD
    - USB-Zip/USB-LS
    - USB-CDROM

    Now, how can I boot from my USB key? Tested all of those 3 options, non works.

    -- Note
    The USB pen is formatted as FAT32, is that okey or does it have to be formatted as NTFS?

    Re: Unable to boot from USB

    On some computers, the USB drive is mounted as just another hard drive... see if you can find a "hard drive" option that allows you to set the boot order of the different hard drives, then move the USB drive to the top. (This is the method I use on my eee pc.)

    it can also be detected as a floppy drive (yes it's true)
    but some pc's just can't boot from usb.in these cases where you have no cd and can't boot from usb .
    you have 2 options
    a floppy boot(not sure how you do this)

    secend one needs windows to download unetbootin and do a net install
    hope this helps

    Yea I went a little bit deeper in my BIOS and noticed something like "Read USB Boot as FDD or HDD" Floppy Disk or Hard Drive. It was on Auto Detect and I canged it manually and tried to Boot both options, neither worked. :/

    Nwm people, thanks for the help, found a solution, just threw the disk in my computer, and decided to wait. After seeing the same error message over and over again for at least 6 minutes it got "fixed" or something, dont know, dont care, I got linux again..

    I tried unetbotin aiming for Net Install and it seemed to still want to write to the floppy (which I can't BOOT from)

    Any suggestions on how to make a NET Boot CD?

    Unless of course I can load windows and then launch something off the USB to start a NET or USB installer...
