Suggested repair: __________________________________________________ ____________

The default repair of the Boot-Repair utility would reinstall the grub-efi of
sdb2,
using the following options: sdb1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file

Blockers in case of suggested repair: __________________________________________

/target detected. Please close the Ubuntu installer, then retry.

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your UEFI firmware boot on the Ubuntu 22.04.1 LTS entry (sdb1/efi/****/grub****.efi (**** will be updated in the final message) file) !

Sometimes this seems to happen in *buntu installs, mainly when it tries to update the grub package by downloading a fresher one.

Try again, but un-check the ;download updated' option AND make sure you are disconnected from the network, so it doesn't still try and update it anyway.

boot-repair's 'suggested repair' might work, though if it has to download the files it could just fail again, since grub never got installed to begn with. On a fully installed system, boot-repair's suggestion would work, as you'd have some grub files to work with.
Your system is not fully installed.
I'd not mess with boot-repair myself, I would just reinstall without a network connection.

HI. THANKS FOR THE ANSWER, BUT IT DID NOT WORK.
I tried to do as you said and same resul.
Any other solution?
Can I install GRUB manually?

See my thread on this same error I got trying to install Kubuntu, and which I solved. https://www.kubuntuforums.net/forum/...eds-assistance
