How can I boot an Ubuntu 18 live USB from GRUB? [on hold]












0














I have Ubuntu 18 and Windows 10 installed in dual boot on my machine.



I now have to do some tuning on the disk partitions and wanted to do it with the gparted available directly on the Ubuntu live USB.



The problem is that I cannot manage to get the USB booting.

I unfortunately do not have access to the BIOS. Before I installed Windows, GRUB was directly booting the USB when I typed exit on the grub> command line which is how I could install it, but now when I do exit at the GRUB command line it boots directly to Windows 10.



How can I boot to the live USB from GRUB?



I tried the solution posted in How to change boot order in grub2 to include bootable USB? and also mentioned in this blog post and it did not work.



To give more information:

it is a UEFI boot



here are the information about the USB I get using
lsblk -o name,mountpoint,label,size,uuid



NAME        MOUNTPOINT                 LABEL         SIZE UUID
sdb 7.2G
└─sdb1 /media/rayan/UBUNTU 18_0 UBUNTU 18_0 7.2G 466D-342D

    Welcome to Ask Ubuntu! :-) Unfortunately, the boot process before Ubuntu is run is a feature of the BIOS / UEFI firmware, so you need to get that sorted first as those questions are off-topic here, but on-topic over at superuser.com, a sister site to Ask Ubuntu.

    Try configfile entry here, example uses your label, so make sure it has a label. askubuntu.com/questions/344125/… Or use a chain type entry to /EFI/Boot/bootx64.efi. Assumes newer UEFI boot, not old BIOS boot.

  • @oldfred I think I tried this too. But did not try with a chain type. It is a UEFI boot btw. What would be the difference for a chain type entry?

Thanks to @oldfred I found a solution by using this one



I had to modify it for my case like this:



menuentry "Ubuntu 18 live" {
search --set=root --label "UBUNTU 18_0"
configfile /boot/grub/grub.cfg
}


and it worked perfectly

    Booting Full Install Flash Drive from Internal Grub



    What works for me is to:




    • Boot the computer from the internal drive.


    • Plug in the Full install USB drive.



    • Open Terminal and run:



      sudo update grub



    • Next boot, Ubuntu from the USB drive, should appear as a grub option.



    Note:
    Running update-grub automatically adds the new menuentry(s) to 30_os-prober.
    The menuentry(s) can be cut and pasted to 40_custom if desired.
