I downloaded the latest version of gparted-live: ver 126.96.36.199 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 programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc//copyright.

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?
