Please take a look at this wiki page first https://wiki.archlinux.org/title/Improv … ot_process

There are more information that we need to be able to inspect this further,

* what boot loader did you use?
* did you use custom mkinitcpio?
* what is the output of `systemd-analyze blame`?

Unplug any cables or devices from you computer, except for mouse and keyboards.

Disable any boot animation or splash.

Reboot and inspect the logs with "journalctl -b". Pay attention on which line consume the most.

For reference, see this reply on the almost the same topic: https://bbs.archlinux.org/viewtopic.php … 2#p2221692

Could also be an internal drive (delay is split between firmware - ie. before any OS loads) and the kernel.
Make sure to also check https://wiki.archlinux.org/title/SMART

Re: Boot slow 1min 26.893s (kernel) Why?? What can a do fo fix it

I did the check in UEFI and all is OK

I did try different boot manger like ufiboot stub and boot time is fast but I can't login when I type password and klick enter mouse cursor disappears and nothing happened.
I try with both KDE and Gnome the same issue.

Now don't even grub works with login

What do you mean "check" and "all ok"? The system requires 90s to get through the uefi and another 90s to load the kernel.
Post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Well I can't log in
When I enter password nothing happened at login.
The system stays att the same login and nothing helps that inc keyboard or mouse

Just nothing ??

Try to boot the multi-user.target but quite frankly: boot something like https://grml.org and check the smart data of your drives because this increasingly sound as if your disk dies.
