Ubuntu 14.04 USB flash drive isn't recognized during boot.

I have had a bunch of hardware failures this week and I am down to a hybrid image laptop harddrive with mint 12 installed on it to boot as /media/cdrom but I can't add to the OS, and I have to reinitialize everything each boot. I'd like to get wine/playonlinux up as well as some drivers for a soundblaster xtigy and live externals, midi, and usb devices such as m-audio and akai devices for FLStudio

I have downloaded unetbootin and Ubuntu 14.04, my hope is to install a new installation onto the harddrive with mint 12 on it, as I can't do a full install from the drive, so I figure if I make a usb flash of Ubuntu I can do an install of Ubuntu from the flash drive.

I managed to install Ubuntu 14.04 desktop amd 64 with unetbootin - I partitioned a 4GB staples relay UFD (universal flash drive) with a fat32 partition it shows up as an EFI system parition after the .iso was installed by unet boot in -- I did flag the drive originally as a boot flag drive when I originally formatted it but after install the boot flag is no longer there (is this because it is an EFI partition?) It shows up fine, but after booting, and I changed my boot configuration to boot USB first then Harddrive. I removed my mint drive so only the USB was in after the first failure that booted into mint, and with just the USB drive, nothing detects during boot.

I am pretty darn certain the problem is boot related, in that the USB isn't being recognized as a boot device.

Is this because EFI isn't supported on Ubuntu usb drives, only ubuntu cd drives?

Do I need to install a usb version of ubuntu rather than desktop amd64?

Do I need to alter the .ISO to install a different boot?

Note I still have mint12 running off a separate drive but it is a pendrive install of a hybrid image, I think I might have grub running, could I just add the flashdrive to mint12s's grub so I can boot off it from grub rather than BIOS?

None the less I'd really like to get a persistent Linux going whether ubuntu or mint.

What exactly do I need to do to get Ubuntu running from the 4gb flash drive and recognized by the Dell Latitude d630?

  • So have you installed Ubuntu 14.04 on the usb drive only, or did you managed to install it on the computer, but you still want to boot form the flash? Clean uo the question a bit. Because the problem in the first case might be UNetBootin. It tends not to work for me nowadays. Try to use another usb utility and create an image with no persistent storage if you only need it for install.Also you might try disabling secure boot see if it helps, but most likely UNetBootin messed up. – jetpackneedsrepair Aug 01 '15 at 12:06
  • What OS did you make the USB image on? If it's windows then it's almost certainly UNetBootin's fault. Try using imageusb . – jetpackneedsrepair Aug 01 '15 at 12:25
  • @Fabby I wouldn't call this off-topic as it seems clear (at least to me) that the OP is trying to install Ubuntu 14.04 dual boot with an existing OS (the type of which is mostly irrelevant IMHO) – Elder Geek Aug 01 '15 at 13:02
  • @ElderGeek: you're absolutely right! Sorry! Close vote retracted! – Fabby Aug 01 '15 at 13:10
  • it was put on the 4gb staples usb flash drive with unetbootin - the staples usb flash drive has not been recognized at boot so it has not been able to be used to put on the laptop harddrive. – William Ashley Aug 01 '15 at 16:18
  • I have a hybrid version of mint 12 on the harddrive that I am using now, but it deletes everything each reboot and I want to get a stable system that has wine/playonlinux to run flstudio and my music hardware. It is frustrating to reinstall every packages, each reboot. – William Ashley Aug 01 '15 at 16:21
  • what usb utility do you recommend to run on mint 12 to install the ubuntu iso. I have checked the md5 on the iso and it matches – William Ashley Aug 01 '15 at 16:23
  • Secure boot in the bios or boot sector? – William Ashley Aug 01 '15 at 16:23
  • I will check image usb and see if I can clean install it sometime over the next hour after I get an expresso – William Ashley Aug 01 '15 at 16:25
  • I'm off to reboot and see if I can find secure boot on the dell latitute setup screen, then try to burn the image to the staples usb with imageusb. – William Ashley Aug 01 '15 at 16:28
  • @WilliamAshley using dd as outlined in the answer below should result in an installer on USB. Intalling to a USB drive from any live media is no different from installing to a hard drive. Booting from USB is easily done by choosing it as the default boot device in your BIOS. – Elder Geek Aug 03 '15 at 17:45

As the D630 is an older model I don't believe UEFI has anything to do with it. Double check system requirements here I would avoid unetbootin as in my experience success is rare. I've had excellent results using dd to duplicate the iso to a USB flash drive. The process to do so can be found in here. Basically you just connect the flash drive you wish to install the image to and insure it's not mounted then issue the commands which you will need to edit as explained below. DO NOT copy and paste. Read the entirety of the answer and insure you have the device name correct before proceeding.

sudo dd if=YourUbuntuImageName.iso of=/dev/XdY
sync

Where YourUbuntuImageName.iso is changed to the name of your Ubuntu iso image and /dev/XdY is changed to the device name of the flash drive you want the image duplicated onto. dd uses a default block size of 512 bytes which you don't have to change. If you want a progress report during the "burn" you can install dc3dd with sudo apt-get install dc3dd and substitute dc3dd for dd in the command. The output of mount and sudo fdisk -l can be useful in determining the device name.

This will result in a USB bootable installer for Ubuntu. Boot from it using BIOS (I believe the D630 will let you choose the device to boot from if You repeatedly tap F12, to get the boot options menu) having booted from the installer, install Ubuntu normally choosing as the target the flash drive you wish to install to.

Installing Ubuntu to a flash drive is no different from installing it to any other drive. Your BIOS determines which device is booted from. You can create your own "persistence" with normal partitioning methods if you want home on a separate partition but installing Ubuntu normally to a flash drive will result in persistence of settings and installed apps (just as installing to a hard drive would) anyway so it's not truly necessary. Here's where you make the changes on a Dell D630 to allow USB Boot. F2 at Dell Logo should get you to the BIOS.
