#A Bootable Flast Drive For Ubuntu On Windows 10 BootUnfortunately The

Sometimes a virtual machine won't cut it for me typically due to memory, disk and performance limitations. Here's a screenshot:I regularly have the need to try things out on Linux. Then mount the ubuntu.iso file with the below commands in terminal: sudo mkdir /media/iso/ sudo mount -o loop /path/to/ubuntu.iso /media/iso Insert your USB flash drive. Place the ubuntu.iso file in any hard disk partition. Creating a bootable Ubuntu USB flash drive from terminal.

ISO to USB also supports the creation of a bootable USB. It is tough, but I'm writing this from my portable Ubuntu Linux installation running off a USB-attached SSD! What you needInstalling Windows on a Mac should be a piece of cake with Bootcamp, but that rarely is the case. Moreover, all the preparatory work has to be performed using a single-boot Windows computer without ending up having a dual boot system. That entails having the Linux installation on an external, USB-attached hard disk drive which can boot with relative ease on any UEFI-enabled PC (driver compatibility notwithstanding).

An empty external (USB) hard drive. The computer will restart using the new settings, booting from. Save the change and then exit the BIOS Setup. Move USB device to the top of that hard drive list. Alternatively, if you feel confident using the macOS command line, see the community documentation on How to install Ubuntu on MacBook using USB Stick for a more. See our How to burn a DVD on macOS for further details.

I have a Macbook pro (late 2009) running OSX 10.6.8. You should see EFI Boot which has a nice little USB Drive Symbol on it in the. YouвЂ™re ready to reboot: During the startup of your Mac hold Alt/Option. You should have 2 files on your USB drive now: bootX64.efi and boot.iso both in /efi/boot. For those of you worrying about performance, the USB 3.0 port is faster than the maximum transfer rate of any SSD I've seen to this date.Copy the Ubuntu image into /efi/boot/ on the USB Drive, too and rename it to boot.iso.

You will need them both! CaveatsHaving a dual- or multi-boot system isn't as straightforward as it used to be a decade ago. Also test both your bootable media. If it breaks don't cry, I warned you. You are going to make changes to your computer.

FastBoot caveatsMany boards come with some sort of 'fast boot' or 'boot optimization' options. I suggest turning off Secure Boot if possible. Even though Ubuntu does support Secure Boot (it comes with signed bootloaders) I have no idea if my method uses the signed bootloaders or not. Secure boot caveatI have only tested these instructions with Secure Boot turned off. Below is a selection of problems that got me moderately stumped along the way. Given enough experience and patience you can work around them.

USB host controller caveatSome firmwares will present the USB host controller as UHCI (USB 1.1) at boot time. It's best to understand what it does and disable it if you plan on writing to your Windows drive from Linux. This feature takes some shortcuts when it comes to booting and also makes the NTFS filesystem remain in a dirty state, making it unwriteable from Linux. I had to disable both.It's worth noting that Windows 8 and 10 have an Fast Startup or Fast Boot feature. It also has an option to support Intel Rapid Start Technology which does get in the way of booting to multiple OS.

Therefore the Linux boot will hang forever without any further indication as to what went wrong.Most affected boards (including my Intel NUC) have an option to enable the xHCI host controller interface by default. Therefore the controller resetting means that Linux can no longer communicate with the USB-attached hard drive. At this time Linux loads the xHCI driver and the USB host controller resets itself.However, your root filesystem is inside a device attached to this USB controller.

Remember that you may have to enter your computer's boot manager to do that (on my Intel NUC I have to press F10 on most other BIOS I've seen it's F9 consult your BIOS documentation).Install Ubuntu Linux regularly. Installing LinuxBoot your computer from the Ubuntu Linux bootable USB drive. If you are only using modern operating systems with USB 3 support (anything newer than and including Windows 8.1 and Ubuntu Linux 15.04) you can safely enable that option.

For starters, the external HDD is not portable as you cannot boot with it on another computer.Secondly, if you remove this external HDD your Windows won't boot. Therefore it adds itself (actually, the bootloader it uses, GRUB2) to your computer's UEFI configuration. Fix Windows 10 bootUnfortunately the Ubuntu Installer assumes that you want a dual booting configuration alongside Windows. This guide assumes the use of btrfs and will point out the caveats with this approach. For your sanity's sake I recommend using ext4. I chose to create a modestly sized root partition (about 40Gb), a swap partition that's as big as the biggest RAM configuration I am going to be using this installation with plus one Gb (my computers max out at 16Gb so I made a 17Gb swap partition) and the rest of the disk went to a massive /home partition.Caveat: I chose to use btrfs which вЂ“ as I learned along the way вЂ“ makes things a bit more complicated down the line.

It will have a volume ID, let's say 99. Verify that the EFI partition is using the FAT32 file system. Select the operating system and click Next.

Again in the command prompt type: Now we need to fix the boot record. Back in the command prompt type:

We have to create one on your hard drive. An ESP is simply a FAT32 partition with a special flag that tells the EFI BIOS to look inside it for boot information. Create an ESP on the Ubuntu HDDA hard drive is not bootable with UEFI unless it has an ESP (EFI System Partition). From our trusted command prompt:At this point exit the command prompt and shut down your computer.

Identify from them the drive that has the Linux partitions, in my case /dev/sdb. Run sudo fdisk -l to get a list of partitions. Boot with the Ubuntu Linux bootable USB stick using the option to try Ubuntu before installing.

Of course it is, I am using it to run the computer off it, duh! I will call it /dev/sdXY from now on.Why not just click on GParted on your desktop? Well, I kept receiving errors about the Ubuntu Linux bootable USB stick because it was already in use. Also identify the partition that contains the root filesystem.

One more thing! Note down the the partition that contains the ESP filesystem. This is what makes the partition 'special' to the EFI BIOS. Set the boot and esp flags. You need to do that now for the next step to be possible. Create a new partition on the free space, changing the file system to fat32.

01234567-89ab-cdef-0123-4567890abcde Note down the UUID, e.g. Double click the partition with your Linux root (/) filesystem on the external HDD Launch GParted from the Terminal, as we saw above: Otherwise GRUB2, the Linux bootloader, won't be able to update itself, making your system unbootable after the next kernel update at the latest.

Otherwise you'll never be able to install GRUB and you'll probably lose an entire day, like me. We need to mount the btrfs subvolume containing the root partition instead of the entire partition. You used ext4) sudo umount /media/ubuntu/ 01234567-89ab-cdef-0123-4567890abcdeIf you DID use btrfs, you made your life complicated. 0123-ABCDThe process is different depending on the format of your root partition on the external hard disk.If you DID NOT use btrfs (e.g.

When you have an external drive it is critical that you use the -removable option in the last step. We need to put a bootloader in it to make it actually, well, bootable.First caveat: all the instructions you find on-line assume you are using a dual boot system with Windows or macOS. Comment it by placing a # in front of it.UUID= 0123-ABCD /boot/efi vfat defaults 0 1Install GRUB2 on the external drive's EFI System PartitionRight now our external drive has an empty ESP. There is a line with /boot/efi already in this file. Umount /media/ubuntu/ 01234567-89ab-cdef-0123-4567890abcdeThe rest of the instructions are common, no matter if used btrfs, ext4 or something else
