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

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 these links:

    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.

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 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.

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.

I have been struggling for ten years with the problem that an older computer (32 Bit Acer Aspire One) BIOS does recognize my USB .iso file. I just today found the answer from a wiser person than I and I want to share this with all of you.

Here is how to do it properly: If your computer has only LEGACY boot mode, the USB stick has to have a MBR (Master Boot Record) partition table before making a .iso installation (boot) file. And the USB should have a single FAT32 partition.

If your computer is in UEFI boot mode, the USB stick has to be formatted to have a GPT (GUID Partition Table) partition type.

So in short: if your USB has a GPT partition table, it won’t work in legacy-computer, and if your USB has a MBR-partition table, it won’t work in UEFI-computer (might work since UEFI is the new standard and may be backwards compatible).

THE SOLUTION IS: Change partition table type (MBR vs GPT) of the USB to correspond the boot mode of the computer (Legacy vs UEFI).

In Linux you can change partition table type of the USB stick in GParted or KDE Partition Manager and your problem is solved: Your computer now recognizes the USB stick!!!!

Sometimes GParted and KDE Partition Manager won't do the job. Then you have to use program called Disks, which will erase old partition table and create new.

However, when I tried to re-do an install to the same Acer Aspire One, it did not succeed.

After multiple attempts and hours of research, I did find a writing that said that another USB device connected to port near USB stick may cause the computer not to recognize the USB iso-stick.!!!

I had a mouse connected to port next to USB stick and removing the mouse everything worked again: Computer recognized the USB .iso and started booting from it.

So remove all other USB devices before inserting an USB .iso.

UPDATE: Trying to boot from USB iso third time gave following error: USB 5-5 device descriptor read/64, error -71 and solution was found in here:

By adding the following line to /etc/modprobe.d/options (I did not have an options file there, it had a different name):

options usbcore use_both_schemes=y

computer recognized USB stick and it solved this problem.

I was unable to boot from USB key with an ASUS N53s Laptop with a key made from Lunbutu V18 to setup an Ubuntu V20.

Seems the key use the UEFI mode. The BIOS saw it, the GRUB menu was displayed but stalled after pressing Enter key.

So I reinstalled the key from Windows using Rufus (look like it make a not UEFI one) and I used the "Bypass boot order" or "Boot override" section provided by the ASUS BIOS. The section list all the connected USB devices, you select the one you want to boot in directly and it worked !

Putting the USB key, first in the boot order was no enough, it was looping into the BIOS menu.

I encountered issue when trying to boot ubuntu 22.04-lts on HP envy x360. I wrote here how did I resolved it: https://chanon.info/install-ubuntu-22.04-on-hp-envy-x360/

Basically, with Rufus, you need to enable 'Add fixes for old BIOSes' option. Hopes this help.
