Can you get grub menu by pressing escape key just after UEFI/BIOS screen?

Yes I can do this

And if UEFI fast boot on, it will be too quick.

Fast boot is disabled in uefi

Do full power shutdown & "cold" boot to get UEFI/BIOS to rescan system and give just enought time to press escape key.

I waited 2 hours and tried to download again using the boot menu (escape). It did not help

Then can you boot recovery mode?

Yes, I can boot into recovery mode, but this also does not give any results, I fall into the busibox shell again with the same error

Or manually edit grub entry with e key.

If you don't mind, could you tell me how I can do this? Based on your advice earlier, I have already changed some parameters grub.cfg. Therefore, now during startup, when I press the e button, I see that there are hd0 and ahchi0 everywhere. I can also attach a photo of my changes.Maybe this is a stupid question, but should I have changed gpt2 to gpt1?)
I want to clarify that I changed exactly grub.cfg which is located in the sbd2 section
Made changes using sudo nano

Have you tried typing "exit" (no quotes) at busybox?

Yes, I tried to enter the output in the first screenshot. Thanks to this method, I learned that during boot the system cannot include the partition with the system enabled (sdb2)

The problem also persists on any Linux distribution. (I tried Mint, Fedora, Kali, Debian)
But the error is changing. Now I can’t really name any other errors.

Hi,

What do you mean with that you downloaded Ubuntu onto a flash drive?
You should have downloaded Ubuntu onto your hdd or so and from that created a bootable usb (flash?) drive.

Friends, what do you think the problem could be?
I reinstalled Ubuntu and I see this error again, but with a different uuid
O Great Oldfred, come to my branch

I can post the command results again if needed.

Can this statement be true?

I suspect either /boot/initrd.img is missing drivers to access the drive.

And how can you fix this? I'm ready to help =)

Hi,

Reading your original post I knew you would encounter difficulties, for you can't boot from a flash drive onto which you downloaded Ubuntu, or whatever distribution, directly. What you downloaded is a so-called image, which you should use to put it onto a flash drive using a special program, for Windows or for Linux, the name of which you should find for your self.
On the site of Ubuntu you can find info for installing Ubuntu which you can use.

Hello,
I followed this instruction:
Install Ubuntu desktop | Ubuntu
What else can I use? =)

[oldfred]

Are you doing LVM/encrypted install?
Since reinstalling try just ESP & / (root) as ext4.
If it does not boot, then run Boot-Repair and post link to summary report.

Please copy & paste the pastebin link to the BootInfo summary report ( do not post report), do not run the auto fix till reviewed. Use often updated ppa version with your USB installer or any working install over somewhat older ISO.
