I am a new user for Ubuntu. I downloaded 13.10 yesterday and made a bootable USB with universal USB installer on my Lenovo IdeaPad Z580 laptop which is now using UEFI; everything appeared OK.

When I booted from the LiveUSB I got the choices of trying or installing Ubuntu but both of them keep giving me these error:

[ 1.929082] kernel panic-not syncing vfs unable to mount root fs on
unknown-block (0.0)

Please tell me what is going wrong?

  • @Aaron - depends what you mean by name - I think you mean the computer's make and model? – Wilf Jan 2 '14 at 19:14

    @wilf: Sorry, I should have been clearer :). That's what I meant. – Aaron Hill Jan 2 '14 at 19:29

Perhaps the USB may not have created the filesystem properly, so I would reformat the USB Flash Drive (as FAT32, the most common format for bootable USB FlashDrives) then reinstall the LiveUSB with Universal USB Installer again.

When the PC reboots, disable the UEFI function in your BIOS. I believe the BIOS listing should be UEFI/Legacy Boot and changing that to Legacy Only will solve the other possible source of your problem.

It's also a general good idea to specify which version (e.g., Ubuntu with Unity, Ubuntu GNOME, Kubuntu, Xubuntu or Lubuntu) of Ubuntu you are trying to install.

  • computer(Lenovo Z580) is using UEFI, version is 13.10, please tell me why FAT32 formatting?? Thanks. – Muhammad Emad Jan 2 '14 at 19:25

    @MuhammadEmad Fat32 is a universally recognized filesystem, and most systems can read, even old ones, so you don't have to worry about your computer's ability to read it. – RPiAwesomeness Jan 2 '14 at 19:27

Trying to install Ubuntu from a USB disk on a Windows 7 system led to a lot of errors. I found that, in addition to disabling Windows active security protection during the time I was using uNetBootin but also that my flash drive was too big (64gb).

For me the issue was that I was using exFAT which is a proprietary filesystem. Since it is not generally recognizable, that was the first error. In order to get around this, I ran: FORMAT/FS:FAT32 E: (E: being my USB drive).

After this, installing with UNetBootin went fine. But do not use exFAT to try to install from a USB drive, it's not supported.
