I moved the USB over to the Notebook and booted up. It showed the Lubuntu emblem but otherwise the programme is stuck

Did you try safegraphics mode? To see where the usb is hanging, at the grub menu for the usb, press e for edit and delete the splash and quiet, press ctrl-x to boot

With the problems you are having suggest to give ventoy a try to put the iso onto the usb:
https://www.ventoy.net/en/index.html I think Ventoy should be able to boot the iso without the need for modification of the iso

Thanks fatmac, I need to go very slowly here so I don't make a royal screw up.

1.when you write

Quote:

file.iso

do you mean the actual name of my iso file or
Quote:

file

like a generic command? I'll wait for an answer before I try

.

2.Thanks, I removed and re-inserted the USB and it's back to sd1.

3. I haven't upgraded my bios as yet. I want to follow the instructions given by you and colorpurple before i go off on my own and upgrade.

I went through the steps I gave earlier and the usb would hang on unable to find medium. After some trial and errors I think this will work:
Open a terminal cd to Downloads folder

Code:

sudo dd if=lubuntu-22.04.1-desktop-amd64.iso of=/dev/sdb bs=4M
sync
sudo mount /dev/sdb2 /mnt/usb
sudo rm /mnt/usb/EFI/boot/*
sudo cp bootia32.efi /mnt/usb/EFI/boot

If this doesn't work, I can only suggest you try ventoy

Yes, where I wrote 'file.iso', use the actual filename.

Hi fatmac and colorpurple. I tried as suggested without success. So over the weekend I thought I would do a "re-set".

The important lesson I learnt from these attempts is what you have told me: that downloading an .iso file and copying it is not sufficient to make a "live' USB. The programme needs to be 'revitalise" by another programmme like Rufus or Startup Disk Creator.

In my case I need to choose the BIOS format for the USB --FAT32.

Third I have to add the EFI bootreader

Quote:

bootia32.efi

.

Right now my USB is not showing the .iso version. My file tree shows:

Quote:

File system
607 GB Volume
Lubuntu 22.04.1 LTS amd64

The odd thing is that in an earlier iteration I right clicked on the Lubuntu file and extracted the .iso version. It appeared below the non .iso version. However I couldn't just eject the USB, I had to unmount and then eject. The.iso disappeared!

My plan is to blank the USB and try again using Startup Disk Creator.

Usually there is more than one way to do something. Did you try the suggestion in post 48?

RenH · 02-20-2023, 02:53 PM

Yes I did.

RenH · 02-20-2023, 02:57 PM

Here's what i got:

Quote:

dd: failed to open 'lubuntu-22.04.1-desktop-amd64.iso': No such file or directory

colorpurple21859 · 02-20-2023, 03:39 PM

you have to cd to the location of the iso file or put in the whole path name, It will be Downloads/lubuntu-22.04.1-desktop-amd64.iso if you are in your home directory, /home/reynold/Downloads/lubuntu-22.04.1-desktop-amd64.iso will work regardless of what directory you are in. The same thing applies when you go to copy the bootia32.efi
The command pwd will give the directory you are currently in.

RenH · 02-21-2023, 12:01 AM

Hi colorpurple,
I had written out the entire path before but I tried again; still no dice. Now I examined the graphic display of the lubuntu file on the USB and there is not even a hint of an .iso file. Nothing to extract either. I have two USBs with the identical version of Lubuntu, so somewhere I failed to make a live USB. I do know that I had the .iso version. I think the reason was I just copied [not knowing what i was doing] Lubuntu to the USB and then I extracted the iso version because I had two labels on my tree file The first was Scandisk 7.2 gig and below was the extracted Lubunu iso version. However, I couldn't take the USB and plug it into the Notebook without losing the .iso version.
I think the problem right now is that I don't have an .iso version. So I am gong to redo one USB starting with Gparted.

I had it running perfectly well on an old Toshiba Satellite, 1.3GHz single core with just 2GB ram, admittedly a little slow on the internet, but perfectly fine otherwise. t tv

I changed the cp(copy command) to rsync in post 25. See if using rsync gets you any further in the booting process of the usb.

RenH · 02-21-2023, 03:11 PM

Here is what I did after

mkdir

I have two USBs. I want to use one and follow the process of copying the Lubuntu to the USB and then extracting the.iso.

indicates ubuntu-22.04.1-desktop-amd64.iso is not in the Downloads folder. Until this is fixed the commands following are useless. What happen to using the lubuntu iso?

Don't know what you mean by this.
Are you doing this from a live iso on a usb?

colorpurple21859 · 02-21-2023, 04:38 PM

Maybe this will be easier, reboot the system,
Open file-manager find the usb and click on it to mount it, take note of where it is mounted.
Open another file-manager window go to the directory where the iso is you want to use
Right-click the iso and select mount
Go to where the iso files are located
Click on view in the ribbon and select view hidden files
On keyboard ctrl-a ctrl-c
Click on window for usb ctrl-v to copy files to usb
Once done coping copy paste bootia32.efi to efi/boot on usb
