The iso9660 filesystem was designed decades ago to be used on a CD/DVD and by design is read only. Doing an online search for iso9660 filesystem should give you any number of results with sites explaining it.
The Ubuntu download site recommends using Rufus. Is there some particular reason you want to use something else? Or have you tried Rufus? Never used it myself so…
HP always want to reset the “ubuntu” entry that the installer creates, usually to Windows and if no Windows gives error on no operating system. You may have to drill down inside the ESP and set shimx64.efi as “ubuntu” entry and move it to be first in boot order.
You just have to go into UEFI settings, and under UEFI should show the ESP efi system partition. And reorder Ubuntu to first.
I have no idea what I am dong. I have no idea how old old fred is but I am over 90 and my memory and everything else is getting really screwed up. Anyway, I am currently trying something new. I am currently asking claude what to do and he seems to have thoughts on int all. I have not started yet but am getting ready to. i can send what I get if you want to see it when I either finish or quit.
I have always used the startup disk creator. what this does is create a memory stick which can then be used to create an ssd. I use a 1tb ssd to do that which seems to be enough to run a system. I now have one but its giving me fits. I am not saying its bad its just different and i gotta figure it out.
In one of your earlier posts, you indicated that one partition on the drive you want to use has the iso file on it and oldfred explained that you cannot boot the isofile directly unless you use a loopback entry in a currently installed Grub bootloader. I would think the startup disk creator would extract and write the iso file to a partition or partitions on the drive you want to use to install. I’ve not used that software so I don’t know what it does.
Startup disk creator is essentially the very same thing as rufus or balena etcher, it is used to flash the iso onto a USB stick to make it an install media to boot a PC from that you want to install Ubuntu on … There is a tutorial at:
If you have installed to SSD, you can post a link to Boot-Repair’s summary report to see if it is correct. But it will not fix the common HP issues of boot order and wanting to boot “Windows Boot Manager” by default. You have to change settings in HP’s system settings.
I am a youngster, only will be 80 next year. In school in 60’s learned Assembler & Fortran. Started with CP/M, then DOS as well as using teletypewriter to connect to mainframe at work. Did not get Windows until 3.1 to have connectivity at work. Retired XP at home to only use Ubuntu.
up to this point its been really easy. You get a computer, remove all hard drives, put in the 1tb ssd and you are basically in business (still have to get the system running right, downlaod programs, etc but that’s pretty much it.
With the HP nothing works, I press the esc-f10 and get the startup stuff bit its not all there. for instance you cannot tell the machine what to boot first (the 1 tb with ubuntu on it). I have now spent a couple days and just failed on everything. I will continue. I think I will try ai and see what one has to say.
thanks for the reply. Hopefully, when you hit your 90’s you still have memory, etc. The good news is that there is evidence that they are getting close to fixing the problem. Hope its true!
I am a bit confused. I have the HP up and running and doing absolutely nothing. I have plugged in the 1tb ssd and the hard drive has been unconnected. When I started I got the setup stuff and was able to setup what comes first, etc. Now i get pretty much nothing but a lot of questions about what I do not understand. Been at it for a couple of days. I will keep on trying. If the HP was a Dell I would have been up and running as I have had several of those and they all worked just fine. It may also have something to do with the 1tb ssd ubuntu 25.04 on it.
I will give the boot-repair community help thing. didn’t know it was there. Is there some way to just test the 1tb ssd? I just checked the boot-repair. Seems they have nothing to say about ubuntu 25.04 I do have several ubuntu 24 1tb ssds. Perhaps I am ahead of myself and should try one of the ubuntu 24’s? (my hope was to upgrade everything - perhaps I should back that one back)
Anyway - I wlll keep on with it all. Think I will try the ubuntu 24 and see what happens.
I just checked again. Actually I had an ubuntu 24 in the HP. I tried the ubunt 25 and it REALLY did nothing. In the 24 I turn it on, it shows a white circle with HP in it, I press either esc f10 or just f10 and it then goes to the startup thing which consists of main security advanced and eufi drivers. Under those there is a bunch of other stuff. I have tried just about everything but nothing does anything it just sits there.
Oh, I have 3 ubuntu 24 ssd’s I have tested them on on this machien and they all work just fine.

Post link to summary report using live installer & downloading ppa of Boot-Repair.

Some systems have old firmware. Best to check that HP’s firmware & SSD firmware are latest versions. Some have solved various issues just by updating firmware to latest available. And what they say is in update is just highlights often many other fixes also.
Compare firmware versions to vendors support site, you can use live installer:
I wrote another one to you a bit ago. When I actually started reading about boot thing I got a bit stunned. Its a program! A program that can help me do what I am trying to do!! My question was where I should download and install on. I have a number of memory sticks as well as ssds. I just couldn’t figure out how much memory I needed for boot repair and if I needed to put the ubuntu 25 on one as well. Then I could have at it.
In the startup stuff I do have the chance to update the bios but, since I wasn’t going to use windows I passed it by.
Best just to install Boot-Repair into any working live install. You have reinstall it every time. But ppa and installing into a working live or any working system will be the latest version. The ISO is not updated as often.
Boot-Repair only fixes Linux issues on booting. But its report can tell us if your install is correct. Its standard fixes are updating or reinstalling grub & kernel. It cannot fix Windows nor other issues.
And if issue is just settings in UEFI, which is most common with HP, it cannot fix that.
Update firmware & review settings in HP’s System settings. Then post link to summary report from Boot-Repair, do not post report.
I’m not sure what the problem is you are having with boot repair as it is just a script you can download and run on any Ubuntu which is explained at the link below. Use the 2nd option explained on the page if you have an installed Ubuntu or derivative.
All HP computers do not have the same options. Generally though, tapping the Esc key prior to anything booting will give you options and usually you will see a screen showing what those options are. The F9 key will allow a one time change in the boot order. The F10 key will allow permanent changes in the BIOS firmware including setting a different OS, drive or partition to boot. When you access the BIOS with F10, you should see a tab at the top ‘Boot Options’ and using the arrow keys on the keyboard to highlight it will show your options in the main window.
If you have an EFI capable computer and highlight Boot Options in the BIOS, there should be a section in the main windows showing UEFI Boot Options and under it OS Boot Manager. If there is a right facing arrow next to it, that means there are multiple options so check that. I don’t know if your computer has these same options so you might give more details as to exactly what you see and do run boot repair but do NOT try any repairs, use the Create BootInfo Summary options suggested above.
Boot-repair has me a bit confused. Right now I hve an HP computer. The only thing that is connected to it is my created 1 tb ssd. I have told it to ignore everything but that as there is nothing else its connected to. Now there comes the boot-repair. What should I put that on? It is suggested that I put it on a usb port. I can, of course, download and put it on one and then reboot the HP. You may also be interested that HP keeps telling me that there is nothing on it to boot with, With the current setup. Wen I turn it on it comes up with the white circle with HP in it. Then it will take me to the system setup. There is a lot of stuff in that system setup but nothing seems to make any difference. It does have a place where I can define what to boot with but I have tried all sorts of stuff and nothing happens. Very strange.
I just did the install. I couldn’t see anyplace to say where I was supposed to put it so it ended up on my machine. I had a usb waiting but… Anyway:
I just did the boot-repair install. It installed it on my machine. I didn’t see anyplace to tell it to put it someplace else. The first two, I assume if I am to put something anyplace those would be the ones.
boot-repair.list
boot-repair.gpg
plus a huge bunch of other boot stuff. It all happened within 2 minutes. I am wondering. What do I do now and what do I delete.
Did some more reading. Seems it wants me to take a created disc that I have installed and running and THEN install the boot-repair which will mean that it will automatically install itself on the working created 1tb that I had installed and have been using all along. That being the case (if so) does that mean I shoult install that 1tb hard drive onto the HP computer?
OK - have now taken the 1tb ssd I use in this computer and moved it to the HD and then tried to boot with it. After a little bit that machine said:
please install operating system on your hard disk (there is none - just the 1tb ssd
that I am in that computer
Then:
Not found
Hard disc (3f0)
f2 for system diagnostics
For more goto www.hp.com/go/techcenters.startup
I did not go for the f2 as that just shows me the system that I have and nothing to do with anything else (I think)
the boot-repair, remember, was installed into this machine when it was dwnloaded so, I expect, the stuff therein are likely to be for this machine and not the one I am trying to get running. I am clueless and confused. I think I will give up on this until tomorrow. My wife is talking about starting dinner.
Thank you for all the time you have spent helping me and apologize. I could have done a lot better several years ago.
Oh, onr last. I took the ssd out of the HP and put it back into this machine to see what happened. Nothing happened. It just booted right up and I am there now.
Do you have a usb stick with the Ubuntu live/installer on it which you can use to install on the HP? Is the 1TB SSD the only drive on the HP? If not, are there other drives? Do they have any operating system on them? If you have the live/installer of Ubuntu on a usb stick, when you put it in the HP on which you want to install Ubuntu, does it boot? If it does, do you see the 1TB SSD which you indicate is attached to the HP?
It isn’t really clear if you have installed Ubuntu to the HP 1TB disk. If you are using boot repair it will only be useful if there is something installed on the HP and can point to problems with booting a Linux OS. If you do not have an Ubuntu or derivative installed on the HP, you need to use the 1st option at the boot repair site to write it to a CD/DVD/USB and boot it on the HP.
