how to make a usb drive bootable with ubuntu

A UEFI bootable ISO image, a FAT formatted USB drive and a machine that runs Linux.

Very basic knowledge of UEFI booting and GRUB, as we are going to generate our own GRUB bootloader image with a plenty of modules included.

Very basic knowledge of GRUB configuration files.

I remember using it with Windows PE around 2005 and it seems to have been updated to support USB drives and UEFI, but remember that this tool also supports legacy booting. If you want to boot Windows too you might want to look at SARDU. Given that the ISO image is UEFI bootable, we can set up a USB drive containing multiple ISOs with different operating systems without creating a mess on the USB drive. Instead of extracting contents from an ISO image, GRUB and GRUB2 have been able to boot from ISO images directly through a loopback device. On Windows versions prior to Windows 8, you press Windows/Super+ R to open the run menu and open diskmgmt.msc, that would open Disk Management. Press Windows/Super+ X, go to Disk Management and check if the partition is marked as active.Press Ctrl+ H in Nautilus to display and copy hidden files as well. iso-file and copy the contents over to your USB drive. Where /dev/sdX would be your USB drive and 1 the partition number that should be used to boot. via parted: # parted /dev/sdX set 1 boot on You're done if you have only one partition on this USB drive, otherwise you need to flag the partition as bootable e.g. You can do something like the following if 604A-00EA is your USB drive and you already have p7zip installed: $ 7z x -o/media/$USER/604A-00EA/ This method also works for other install media that contains EFI loaders, like Windows for example. Use the latest AMD64 (LTS) ISOs, because these definitely contain UEFI bootloaders.Don't forget to create a partition after you've created the partition table.A GPT partition table like in preinstallations of Windows 8 and later is recommended.

You may still need to explicitly tell your computer to boot the media via UEFI.

Remember that for an installation or booting the media: Just copy the files to your FAT32-formatted USB drive. Creating UEFI-only booting USB live media is pretty straight forward.
