Does 24.04 Live USB do verification on startup?

[echaskaris]

I remember this being a thing in older usbs I made.
I'm trying to install 24.04, but there is no progress shown on screen, just purple and the USB flashing, and occasionally stopping.
I'm installing on a Legacy Bios laptop with USB 2.0.
Any idea what's wrong? Thank you.

Booted from a desktop and booted fast with no issue and no file verification.
There must be some bug preventing it from working on the laptop. I can't blame it though, laptop is a bit old.

It's impossible to help much without some idea about the hardware of your laptop. A laptop which is legacy boot only and does not offer UEFI must be earlier than the hardware needed for Ubuntu 24.04

I suggest firstly you should try a lower resource requiring version (Xubuntu, Lubuntu) rather than the default gnome Ubuntu which needs better hardware than you probably have at present.

If you really want Ubuntu, see if it will boot to the live desktop GUI, open a terminal and run command inxi -fzx then post back here the output you see.
Please use Code-Tags for terminal output. See my signature below for a How-to

The laptop runs 22.04 fine. It's a Lenovo Thinkpad L520 with 4GB RAM.
It doesn't enter gnome I think. If I remove the quiet and splash boot parameters it doesn't get stuck with an error.
Maybe I'll do more testing and report a bug.

4G ram is minimal for Ubuntu 24.04 so I still suspect your low resource hardware but to be more sure please run the inxi command I asked for earlier.

I am not sure what you mean by verification. My experience installing Ubuntu 20.04 LTS and 20.10 beta is that it takes time. A lot of time. Even on a NVME drive and longer on a SATA hard drive. I almost gave up waiting thinking the process had stopped.

From 24.04 LTS a different installer program is used. After some time we get a Ubuntu splash screen with the Ubuntu icon screen bottom & centre. Then, after a time a purple screen with a line drawing of a numbat (24.04) or an oriole (24.10) appears. Following this is a white panel that says "processing Ubuntu." All of this takes a long time. Once we have worked our way through the install choices the slide show begins.

In the past the installer would inform us of what packages were being installed. This does not happen anymore. We are told "Installing system" and "setting up the system." All the while red stripes chase each other from left to right at the bottom of the panel.

In the past when we installed from DVD we could hear the DVD spinning and the hard drive spinning. With USB memory stick and SSD/NVME there is no sound. It is easy to get fooled into thinking the process has stopped.

Ubuntu has various products & release, and there is variation between them.

Yes modern Ubuntu install media does self-verify; however the verification process has varied over time. A decade+ ago there was a menu items that triggered that verification, then it was moved to a automatic process that was very visible & caused boot to pause (though the verification could be cancelled if you were fast enough), but due to complaints about waiting, the process was switched to a background one which is still used today.

Myself, if I've not verified the install media before, I'll wait for the background verification to complete before I actually install, I do that as the machine is more responsive when its completed AND I know media problems won't negatively impact installs.

If you want to know more about media checks; I'll provide a link to an answer I've written on another support site - https://askubuntu.com/questions/1311...ubuntu-install

You only specify release, Ubuntu 24.04 LTS ISOs are available using three installers and what I mentioned I know applies to `calamares` and `ubuntu-desktop-installer` (Ubuntu 24.04 Desktop & flavors) but I believe would also apply to `subiquity` ISOs (Ubuntu 24.04 LTS Server)

I still think it's some bug, 22.04 live usb opened and installed fine, and fast too.

Setting "nomodeset" kernel parameter fixed the booting issue, will try to upgrade 22.04 to 24.04 sometime.

Similar thread. Suggest more RAM, faster drive, and lightweight flavor for older BIOS only systems.
