Ubuntu: Cannot successfully create a bootable Ubuntu USB drive


I am trying to create a bootable Ubuntu USB drive.

I tried the Universal USB Installer and UNETbootin to create it but when I booted the USB stick,

error loading operating system  

shows up. I tried changing the BIOS to boot from USB by default but always got the same error message.

When I was in the Universal USB Installer it gave me this error message:

can not open output file autorun.inf

Also an error prompt opens:

An error occurred while executing syslinux.  Your usb drive won't be bootable.  

when it was extracting from 7zip.

The drive is formatted as exFAT. I'm not sure if that is important.

Edit: re-downloading the iso didn't work or formatting the drive.

Edit 2: Since I couldn't format it as normal FAT I formatted it as NTFS and that worked.


Try re-formatting the flash drive to Ext2/3/4, and then when you install, have it format to FAT. That has worked for me in the past.


I would recommend you to format your usb drive and then using unetbootin you can create it bootable.
