Can't boot my Ubuntu OS on my laptop

[PierreZara]

Hi,
I used a external ssd to install a Ubuntu version (Ubuntu 22.04.3 LTS), the goal is to have a "portable ubuntu OS" that i can use on my different computer.
On my 'main' laptop i can boot the OS and use it like a normal OS.

But when i want to boot it on a old laptop: Lenovo ThinkPad T510, i select my USB boot where my Ubuntu is, but i only have a black window with a blink white underscore on top left corner.

On this laptop there no option to select 'boot mode: Legacy / UEFI (see bios picture).
I disabled the security: 'Security Chip' and 'Memory protection' but im always stuck on same black window.

I read this post: https://www.linux.org/threads/linux-newbie-cant-boot-from-usb.28134/, i have the same bios and same computer if you want some details.

Thank you,
Pierre

Hello @PierreZara,
Welcome to the Linux. org forum.
Form the screen shots you posted there are a couple things I would try first. 1. disable the quickboot 2. click on security and make sure secure boot is turned off and give it another try.

Thank for your fast answer,

1. I just have the choice between 'Quick' and 'Diagnostic'; same result when i change it

2. I don't have this option on my BIOS

Try changing the Boot order so USB FDD (Floppy Disk Drive) is changed for USB HDD (Hard Disk Drive).
