Topic: MBR vs UEFI Live USB Boot


  • Model: Msi GL72 7QF

  • Processor: Intel i7-7700HQ; 2.8GH

  • RAM: 16GB DDR4

  • GPU onboard: Intel(R) HD Graphics 630

  • GPU card: nVidia GTX960M, Optimus enabled

  • SSD: 500GB, GPT UEFI

  • OS: Windows10 Insider Preview; Mageia 7; Ubuntu 18.04.3 LTS

  Secure boot and fast boot: disabled

I downloaded the latest version of gparted-live: ver and used mkusb to create a live USB stick.
Using the live USB on my desktop computer with Windows 7 worked flawlessly.
Using the live USB on my laptop (described above) failed to open the GUI.  The following message appeared:

Debian GNU/Linux bullseye/sid debian tty1
debian login: user (automatic login)

Linux debian 5.2.0-2-amd64 #1 SMP Debian 529220190821 x86_64

The desktop is MBR formatted but the laptop is GPT booting in UEFI mode.  In the past the nVidia card required adding mods (nouveau.modeset=0) to the kernel instructions in Grub, but that does not work in this case. I tried all the offered scenarios. Also, both the desktop and the laptop have identical nVidia cards.  I tried all the variations of video parameters in the setup, but nothing changed. 

Apparently the live USB is booting in the UEFI system but not progressing to the user interface.  Is this to be expected on such machines, or is there a solution for booting in the UEFI environment?

You might try the suggestions in Tips on Booting GParted Live.  You might also try one of the other GParted Live images (i686, amd64).


Re: MBR vs UEFI Live USB Boot

gedakc- Thank yoiu for your good advice.  Regarding the additional booting tips:

1- The MSI is configured correctly for UEFI.  Windows 10 came preinstalled with it, plus mageia7 and Ubuntu 18.04 are currently installed and working on the same SSD as Windows.
2- None of the other graphics modes produce a different outcome.
3- Forcevideo does not fix the problem at either of the settings' extremes.
4- Addition of the kernel mods for my Intel and/or nVidia card has absolutely no effect.  The boot outcome is identical with or without the additions.  Could you shed some light on exactly where in the Grub kernel commands these mods should be added? I've been putting them immediately ahead of the "nosplash" instruction.  Is there a better place?
5- Does not apply

I have also created gparted-Live in all three versions of the .iso.  I have gone so far as to create the boot disks using three different methods: Unetbootin, Rufus, and mkusb.  They all end up with the same screen.

Most of the Ubuntu derivative distros using a 5.2.x kernel will boot on this laptop by adding nouveau.modeset=0 and then installing the nVidia drivers after logging in.  Apparently Debian is immune to this fix.  I take it there is no known solution.


Re: MBR vs UEFI Live USB Boot

The GParted Live image is based on Debian Live (SID).  If problems are experienced booting Debian Live (SID) then the issue should be pursued upstream.

Another option you might consider is to boot a different distro containing GParted, such as System Rescue CD.
