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...
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.
Alternatively, you can simply double-click on the file unetbootin-linux* since it will be executable after step 3. To use UNetbootin you simply have to insert the USB drive (or external USB hard drive) and launch the software (see step 5 above for what to type in your terminal).
edit: Alright, i understand this is r/linux and there is bias and anything with Windows is downvoted, but this works. Sometimes friends (or nephew in my case - for school) unfortunately needs to have windows installed and this is an easy solution. So, again besides the downvotes - this works.
I faced the same problem, i needed to put my backup windows 7 copy o a usb drive, but when the drive is formatted as fat32, windows wont boot. The only way to boot windows successfully using unetbootin is to use an ntfs formatted drive, which current unetbootin version don't seem to support, and because the "show all drives" option was missing, i couldn't make a custom selection. so i had to go back and use an older version of unetbootin to get the job done. the last stable version with show all drive option was unetbootin-linux-506. using that will help people who are facing the same problem like me for now. but i really don't think it was necessary to remove that option.
I have an external USB hard drive with two fat32 partitions that I wanted to use unetbootin to load iso images on and make bootable. These partitions would not show up in the menu and I had to use an older version with the 'Show all drives' option to select these partitions. Could the show all drives check box box at least be available after passing a cli argument? ie: 'unetbootin --all_drives' It seems this would still shield the regular users and allow those who know what they are doing to continue.
I'm also wondering why this option was removed, I've rarely been able to get Unetbbootin to find a multitude of my devices (USB Drive, SDCards etc.) I often have to resort to using an older version unetbootin to use this feature...
I am using Windows 7 64 bit and I am attempting to create a bootable USB drive with VMWare ESXi 4.1. I ran this in MacOS and the drive is detected, however nothing produces a bootable drive so I moved to trying the same steps in Windows (they say stupidity is trying the same thing over and expecting different results) however in Windows unetbootin only shows c:\ and not my USB drive. I have tried to format it it on MacOS and Windows as FAT and FAT32. I didn't even try NTFS because it's not supposed to work.
I am attempting to install a CD-bootable ISO into a loopback device to create a new ISO that will properly chainload from GRUB; I use Unetbootin ISOs + GRUB for cleanly segregated multiboot on a thumb drive. For people looking for a tutorial: nevermind, unetbootin doesn't allow it anymore!
After two days of reading and trying, I have come to the following conclusion:
To boot windows 7 from USB stick you (indeed) do NOT need unetbootin for
exactly the reason as is stated at the top.
Note that next you probably want to select an empty disk
(no partition table) and have that FIRST in boot order, and
the flash drive second. That way it will boot from USB the
first time and from the selected HDD that you install windows
to the second and subsequent times during the install of
windows (if it boots again from the USB the whole install
just starts from the beginning; if that happens just reboot
again and change boot order to boot from the selected
HDD).
Have you checked to see if unetbootin created a file named casper-rw in the root of a FAT32 formatted partition on the USB Flash drive? Or, if not, have you checked to see if an ext2 partition named casper-rw exists?
Are you sure you are using a current version of unetbootin, and sure that the flash drive was formatted as FAT32 when using it to setup a USB flash drive to boot into Linux Mint? If it was not formatted as FAT32, that could explain your issues.
Did you use UNetbootin on Linux or on Windows? I used the Windows version. But when I run unetbootin on Linux, it says "extlinux" must be installed, so I apt-get installed extlinux. Maybe the Windows download did not include these tools? Which may be required to create casper-rw as an ext2 filesystem.
Step 1: Open your browser and visit the official website of UNetbootin (unetbootin.github.io). On the home page, you will get the download button for various operating systems, including Windows, Linux and macOS.
