Ubuntu install not booting normally after live boot ejected

[charles-namibia]

I have installed boot repair, attached here is a log, what worries me is line 5

=> No boot loader is installed in the MBR of /dev/sda

Is this why it is not booting?

You can now reboot your computer
"please do not forget to make your UEFI firmware boot on the The OS now in use- Ubuntu 22.04.3 LTS entry(sda1/efi/ubuntu/grubx64.efi file)!

rebooting the computer
and adding the UEFI boot as requested still does not boot though, even, deleting the boot file the the UEFI originally picked as the boot and leaving just new one also does no good, this PC just refuses to boot.....

I am most definitely out of my depth here, for sure.

No boot loader is installed in the MBR of /dev/sda

No. You have an EFI install and no boot code is placed in the MBR but rather is on the EFI partition of the hard drive, the filesystem partition as well as minimal code on the system board. The problem is more likely related to the message below. If you navigate to that directory while booted using the Advanced option in Grub, check to see what directories are there. There should be one named 6.2.0-39. If not, what is there? Check also /usr/lib/modules to see what is there.

modprobe: FATAL: Module efivars not found in directory /lib/modules/6.2.0-39-generic

Your boot repair output shows this:

(sda1/efi/ubuntu/grubx64.efi file)

Line 125 of boot repair shows the efi entry for Ubuntu pointing to shimx64.ef rather than the grubx64.efi. Don't know why that is or if that is a problem. Seems more likely it is related to the NVidia graphics. You might try booting again and when you see the Grub menu, go down to the option under Advanced Menu and highlight the entry you use to boot but instead of hitting the Enter key to boot, hit the e key to edit. This should show the menuentry for that option. Look at the line bdginning with linux and see what the numbers are or the vmlinuz file. If it is the 6.2.0-39, your problem is likely the graphics card.

Hi @yancek I do not know what is going on, I really do not, I can ONLY use ventoy to boot with, nothing else (Rufus or Etcher) will NOT work, I have no other VGA cards to use but the 2060, if I resume boot from recovery then ubuntu boots. I have installed, reinstalled and done all I can. If I try Ubuntu then my screen goes light blue and white and washes out completely and I can only see outlines of icons and nothing else, so, I would agree with a VGA issue, i do not know how to fix it, I have tried everything I can get my hands on and NOTHING works, barr what I have already said, Ubuntu fails to boot on it's own, I can delete the existing boot path and install my own, it does not work, when I boot back into bios, the old boot path is back and selected. The only way I can boot into ubuntu is via the recovery screen, no other way, I am, tired and frustrated, I have been at this for 3 whole days and I am tired.

Are you booting flash drive with Safe mode?
Then choosing to install optional restricted extras to get nVidia drivers?
If UEFI Secure Boot on you have to add your own MOK key machine owner key to authorized it as secure.

If you can boot to recovery mode, boot to command line & run this.
sudo ubuntu-drivers autoinstall

If you already installed an incorrect or want to reinstall a different version of nVidia driver, you must purge first.
sudo apt-get remove --purge nvidia-*
sudo ubuntu-drivers devices
ubuntu-drivers devices | grep recommended
sudo ubuntu-drivers autoinstall

#What is installed
dkms status

Hi @oldfred.

There is an underlying issue at hand. No one seems to hear this..... I have had to resort to Ventoy to be able to run the install, Nothing else will work, all the rest just hang. After using Ventoy, I can run the install of ubuntu to an hdd, once the install is done and the live boot media must be removed so the Ubuntu can boot from the HDD then the proverbial paw paw hits the fan..... Ubuntu does not boot from the HDD, I have to then hold down the power button, force the system to power down, then I have to power on and hold either Shift or escape to get to the grub, once there I choose advanced options for ubuntu to get to the recovery menu and then i can choose resume and ONLY then will ubuntu boot, it will not boot any other way at all, I have tried so many lines of code that I do not know up from down any more, Ubuntu does not boot from a power on at all.

The suggestions in post 14 by oldfred are meant to do that. You say you can boot in Recovery mode so do that then open a terminal and consecutively, run the commands suggested above in the third paragraph of that post.

[charles-namibia]

Yes, I will do that, just need a break now, will revert back when done...

@oldfred

I carried out the code you supplied.

Unfortunately there is no change.

Ubuntu boot problem remains.

Did you get to recovery mode?
Did you get any error messages?

[charles-namibia]

Did you get to recovery mode?

I am going to try explain again, I was not able to boot the live usb with anything other than ventoy, grub2 does not boot at all, only grub, if I run "try ubuntu" then my screen washes out. Running "install ubuntu" then the install runs till the "remove live boot media and press enter to reboot" after that the reboot happens and the system hangs, I have to force a power cycle, hold down "shift key" or "esc key", to boot into grub, after that I choose "advanced settings for ubuntu" then I am able to get into the recorey menu. Getting into the revovery menu is not a problem, the booting is a big problem

Did you get any error messages?

Honestly? So much happened that my head is spinning, the dkms status did come up empty because it was not installed, so, I had to go and read how to do that. If you ask about errors would they be another color or be listed as an error? I am sorry, but I am in way over my head and have no idea what I am supposed to look at anymore.

Sorry, this is all greek to me.
