I have HP G56 laptop and it originally came with Windows 7 which microsoft updated to windows 10 for free. I did clean install and so i don't have option to go back to windows 7.

I want to try Ubuntu as after upgrading to windows 10, my laptop runs slow. I have created bootable USB several times but can't make my laptop to boot. I saw tutorials and already setup bios to boot from USB first and also turnoff fast boot from power option. I can however use other USB for windows 10 that i have and that works but not from Ubuntu USB

    1. Please tell us more about your computer - brand name and model; 2. Turn off secure boot in an UEFI system menu; 3. Which version of Ubuntu are you trying (name of the iso file)? 4. Did you check the iso file with md5sum? 5. How did you create the Ubuntu USB drive (which tool/method)? 6. Does the Ubuntu USB drive boot in another computer? – sudodus Mar 24 '18 at 20:38

    I tried USB on my friend's laptop and it works so some settings are wrong or needed to be tweaked. – Poorav Mar 28 '18 at 11:45

    I believe i do have BIOS mode (not UEFI) on my HP G56 laptop as i do not see UEFI option. I did made USB with Rufus-2.18 so let me ktry ubuntu 16.04.1 ISO instead of 16.04.4 ISO, hopefully that will work. – Poorav Mar 28 '18 at 11:49

    reset bios to default, as may be you have some bad setting preventing boot from usb. Try also F9 during bios to display boot menu. Try another usb device (the fact it works on another pc don't mean it is ok for your pc) – laugeo Mar 31 '18 at 12:01

    I truly appriciate your help. yes lets see what happens. One last thing though, i have win10 bootable use and it do work with this laptop. So i am not sure what bios setting would be wrong but ubuntu usb don't work – Poorav Apr 1 '18 at 13:38

You commented that:

It gets a hangup at boot, it displays "press Esc to see startup option" and nothing happens. If I press Esc then it displays "press Esc to pause" and if press Esc nothing happens. Basically I have to turn off the laptop by pressing the power button.

The Ubuntu live USB that you made with the 1.5GB Ubuntu iso is not loading successfully, so try booting your laptop with the Ubuntu Minimal CD. The Ubuntu Minimal CD is less than 60MB in size, and loads the rest of the packages required to install Ubuntu during the installation process.

How to make an Ubuntu Minimal USB

It is possible to make an Ubuntu Minimal USB on either Ubuntu or Windows Subsystem for Linux 2 in Windows 10 using dd. While the minimal iso image is handy, it isn't useful for installing on UEFI-based systems that you want to run in UEFI mode. The mini iso lacks the proper files for booting the computer in UEFI mode. Thus the computer will boot in BIOS compatibility mode, and the installation will be in BIOS mode.

  1. Download the Ubuntu Mini CD iso file from the link on the Ubuntu Documentation Installation Minimal CD webpage. Download the file called mini.iso to your Downloads folder. You can download the mini.iso file to wherever on your computer that you want, but download it to your Downloads folder so that you can easily run the commands in the following steps without changing anything.

  2. Verify the md5 checksum of the Ubuntu mini CD iso file that you downloaded by running these commands:

    cd ~/Downloads/
    md5sum 'mini.iso'  

    If you are using Windows Subsystem for Linux download the Microsoft File Checksum Integrity Verifier tool from the official Microsoft Download Center. The Microsoft File Checksum Integrity Verifier tool is a command line utility that computes MD5 or SHA1 cryptographic hashes for files.

  3. Check that the results of the command match the MD5 checksum of the mini.iso file on the Ubuntu Documentation Installation Minimal CD webpage.

  4. Get a USB flash drive, 1GB or larger. Delete all the files from the USB flash drive. Mount the flash drive using the Disks disk utility. Or burn the Ubuntu Mini CD iso file to a CD.

  5. Check in the Disks disk utility to find out the device name of your USB flash drive. This is very important because if you use the wrong device name in step 6, you will overwrite your whole operating system instead of writing to the USB flash drive. So check the USB flash drive device name twice. It should be something like /dev/sd* where instead of the * character there is a lower case letter like a, b, c, etc. In the following step I am assuming that the device name is /dev/sdc, but the device name of your USB drive could be something else like /dev/sda or /dev/sdb so check the device name of your USB drive twice and make sure that you get it right in step 6!

  6. Open the terminal or Windows Subsystem for Linux and run the following commands:

    cd ~/Downloads/  
    sudo -i  
    dd if='mini.iso' of=/dev/sdc bs=4096  ## make sure that the device name of your USB drive is correct!

    The dd if='mini.iso' of=/dev/sdc bs=4096 command should take only a few seconds to complete on most computers because the mini.iso is a small file, less than 60MB. The result of running this command will be a bootable Ubuntu mini USB.

  7. Boot the computer from the Ubuntu mini live USB (or CD). The Ubuntu mini live USB (pr CD) should boot successfully and show a menu screen.

  8. If you select the Install option (the complete install, not the cli install) from the menu screen in Step 7, then you can select other options during the Ubuntu installation process to download all the packages that you need to perform a complete Ubuntu installation. Select the Ubuntu desktop package collection from the list of predefined collections of software in the Software selection screen in the Ubuntu mini CD installer. When you restart the system at the end of the installation, you will have a working Ubuntu desktop with the default desktop environment.

  • +1. I would be even happier, if you suggest a safer alternative than dd. There are tools with a final checkpoint ... :-) -- Let us wait and see if @Poorav is helped by this method; maybe we must also help at the BIOS/UEFI level to make the computer boot from USB. – sudodus Mar 31 '18 at 8:19
  • Talking about tools with a final checkpoint, I can refer to this link: Accidentally did dd /dev/sda. You can scroll down to 'Safer tools to create USB boot drives with Ubuntu'. – sudodus Apr 6 '18 at 8:54

My laptop suffered from similar problem, what i did is that i

1- disabled 'fast BIOS Mode' under the advanced settings.

2- disabled 'UEFI Boot support' (although my laptop doesnt have UEFI but this option is there is the BIOS settings, after disabling these it recognises the bootable usb)

    i also have BIOS mode (not UEFI) but still that option is there in boot settings.... – waqar Mar 31 '18 at 11:40
  • 1. I have disabled fast bios but no luck – Poorav Apr 1 '18 at 13:46
  • 2. I do not see UEFI boot support in bios settings – Poorav Apr 1 '18 at 13:46
  • FYI, my bios version is Hewlett-Packard F.15, 4/7/2011. I – Poorav Apr 1 '18 at 13:48

I remember having this problem on an older laptop a year or two ago. It probably has something to do with how the computer is trying to start. Sometimes UEFI won't launch a Legacy USB and vice versa. Make sure you're iso file is for UEFI booting or disable that and use Legacy, but then you need to make sure that your iso file is the one that boots with Legacy.

    Not sure how i do this? – Poorav Apr 1 '18 at 13:51

Try to put your bootable media in USB 3.0 ports instead of 2.0 It seems that 2.0 ports are totally frozen in my case. Ubuntu does not recognize any input in the test mode of bootable usb media and also after I managed to inatall the entire OS including keyboard or mouse.

  • 2
    Also the reverse is sometimes true. If USB 3.0 ports don't work try inserting the USB bootable media in a USB 2.0 port. Also sometimes trying any other USB port works. And if none of these work sometimes trying a different USB stick works. – karel Dec 24 '18 at 14:41
  • I have just experienced this issue in a HP 15-bc451ns, where Ubuntu 18.10 doesn't load in a USB3.0 (marked as USB SS) but yes in a USB 2.0 – Nothor Jan 24 '19 at 19:28
