Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

it says missing bootmngr or something like that. I'm on ubuntu 12.04 or whatever, the newest one using the gparted to format to NTSC and then unetbootin to install the bootloader, and the iso, then restart. also, i do not know how to use terminal or code..and im also using an external hardrive because this laptop is missing one...

1.12.04/2.NTFS/3. I did not undertand what is it that you did. You got the UBuntu ISO, burned it into the USB using Unetbootin..then what? Windows got messed and it says bootmgr is missing? that is fixed using the Windows CD not the Ubuntu USB.. –  Uri Herrera Jul 10 '12 at 22:25

Unetbootin in not intended for making bootable USBs with Windows. Use proper tools for the job, and proper help and support sites as well. –  mikewhatever Jul 11 '12 at 0:18

That worked for me.

  • Format your USB as FAT32 in GParted
  • Open UNetbootin and get it as far as the stage where it brings up the USB partition to install to e.g. /dev/sdb1 - Don't install the ISO, though
  • Leaving UNetbootin open as is, reopen GParted
  • Format the USB in GParted as NTFS
  • If GParted doesn't automatically add the "boot" flag, add it yourself
  • Now, go back to UNetbootin, which you've left open in the meantime, and click OK

Doing so, UNetbootin will think you are using a FAT32 partition and will let you use NTFS format.

EDIT: at this point UNetbootin complained the USB device was unmounted. Keeping UNetbootin open I ran sudo mount /dev/sdb1 /mnt. Then I hit "OK" on the still-open UNetbootin. It wrote the USB image to the USB.

I tried that but I get a "BOOTMGR is missing" message at boot. –  Krige May 21 '13 at 16:17

Cool, a great way to get around newer versions of unetbootin not supporting NTFS. –  Bealer Jun 18 '13 at 20:16

What a great ugly dirty hack! But it's not your fault :) Thanks, worked very well! –  gyabraham Oct 19 '13 at 10:40

a more elegent way with recent versions: unetbootin installtype=USB targetdrive=/dev/sdd1 (for example). This worked for me, YMMV. –  dpb Apr 13 at 20:02

If Windows is what you're trying to install, then Windows 7 bootable USB DVD download tool from Microsoft (Also works on XP) allows you to create a bootable version of windows 7 OS for installing windows through USB drive. To download this utility click Here.

Note: You need to run this on a windows machine.

For more information see Windows 7 USB Creator

Now to create a bootable Windows 7 USB Drive while using Ubuntu, then you need to make sure you have a Windows 7 .ISO file (you can create it from the DVD) and a 4GB USB flash drive (or larger).

Install Gparted and format the USB drive to NTFS. In Ubuntu, use the following command to install Gparted:1

sudo apt-get install gparted

To be able to format a drive to NTFS, you'll also need ntfs-3g - install it using the following command:1

sudo apt-get install ntfs-3g
