I formatted my PC and installed Win7. I want to dual boot with Ubuntu 13.10. After I burn the iso file to 8GB USB stick with "iso to usb", restarted and I get this error:

BOOTMGR is missing

Press any key to restart

I tried formatting my USB (FAT32) but it's still not working.

Thanks for your time. Any ideas?

edit #2: There is a checkbox " Bootable, only supports Windows ISO image. " which the last time I left unchecked before burning.


What program are you using to create the bootable USB? I would suggest UNetbootin if you're not using it. Never had this sort of problem with that program. Download for Windows can be found here:

  • I used "ISO to USB", let's try that. Thanks! – Ekin Jan 11 '14 at 21:35
  • FYI, it still has be formatted in FAT32. – user219730 Jan 11 '14 at 21:36
  • Okay, but I can't see Ubuntu 13.10 on the distributions list. – Ekin Jan 11 '14 at 21:38
  • I wouldn't worry about that. Select the "Diskimage" radio button at the bottom and select your Ubuntu .iso. This is how I've always done it. – user219730 Jan 11 '14 at 21:42
  • Thanks, I have another question also. I've read some forums and people were saying that after 12.10 it was a "downgrade" not an upgrade to change to 13.10. I still think that using the latest version is better. What would you prefer? – Ekin Jan 11 '14 at 21:48

Use Unetbootin or Universal USB Installer (this can also make Bootable Windows in USB).Both of them works fine to make of any Linux Live USB ...

  • I used Unetbootin when I had this problem. I decided to install 12.04 until 13.04 comes out. Now everything goes well. Still thanks for your answer it would be useful for someone. – Ekin Jan 17 '14 at 18:07
