Hello,
This is an English subsection of the forum, if there is one available in your language, please, go in there if you want to speak your mother's tongue.
Otherwise, in English, please :).
Also, funny story: I had this problem yesterday, you seems to have boot the USB live of Gentoo in BIOS mode, not UEFI.
Rebooting on it will allow you to finish the installation process in UEFI mode.
Regards,

Did you boot the live-medium in UEFI mode? Check if the /sys/firmware/efi directory is filled.
Did you chroot correctly? Please show the commands you used. |

Don't you forget to mount /efi ?
You have mounted a partition as boot, it should probably be a VFAT 32 partition, typed as EFI, with fdisk for example. And it should be named /efi, not /boot. So it's the same command (same partition) but you have to mount it on /mnt/gentoo/efi.
/boot is used for BIOS computer, not UEFI.
Did you use a GPT layout for the disk or BIOS ?

Once again:
Check your BIOS setting: CSM mode (some BIOS call it "legacy") must be DISABLED.
Our GentooCDs are dualboot-capable ... IF UEFI-(BIOS) is set to CSM they do an old MBR boot AND THEN you dont have a /sys/firmware/efi directory.

After booting the live medium (don't chroot yet):
| Code: | | ls -F /sys/firmware |
If "efi/" is not in the output, then the live medium did not boot in UEFI mode.

Good.

Yes, every bootable OperatingSystem (for UEFI) - every Linux and also Windows - use this NAME because it is a hardcoded name every UEFI understands. As you surely already know you must make an UEFI boot-entry to boot a kernel or bootmanager or Windows ... but you dont want to do this for every USB stick (or bootable CD). Therefore UEFI invented this hardcoded name. Now you can boot this WITHOUT having a boot entry. You must know: BOOTx64.efi IS the grub (only renamed from grubx64.efi to this name). See more here: https://wiki.gentoo.org/wiki/EFI_System_Partition#Removable_media
| borje2 wrote: | | shall I only have directory /efi? Not /boot |
You will need both directories. You mount your ESP (EfiSystemPartition) to /efi ... and then later grub-install will install your grubx64.efi (=first part of grub) INTO /efi/EFI/gentoo/grubx64.efi ... and ... the second part of grub INTO /boot/grub
Please read: https://forums.gentoo.org/viewtopic-t-1165115-highlight-.html

Sorry, I dont understand your question. Please describe in other words what you mean.

I get more confused with UEFI
shall I have 2 diffrent directory? /efi and /boot both mount on /dev/sda1?
mount /sys is it not in
mount --rbind /sys /mnt/gentoo/sys
and
mount --make-rslave /mnt/gentoo/sys

Two directory OK
mount ESP to /efi I don't understand how to
when I start from live-cd I go into bootsetup
I take
kör UEFI-program
CDROM: hp DVD-ram UJ8E1
EFI
BOOT
BOOTx64,EFI
ls -F /sys/firmware
Show:
acpi/ dmi/ efi/ memmap/

Alright. After booting your live medium, without chrooting, post the outputs of:
| Code: | $ lsblk -o name,mountpoints,partlabel,parttype
$ ls -F /mnt/*
$ mount |

Indeed, I wanted to say: /boot is used to install GRUB for a MBR/BIOS case (but also used in GPT/BIOS case IIRC), got a bit quick to answer.
That /boot partition will be where grub-install works on BIOS system.
While /efi is used on an UEFI system, and is used as the directory where you use grub-install command.
Is that more correct ?

No.
I don't like the term "the /boot partition". If it means anything, it is "the partition that you mount at /boot", which is a user's choice and may very well be none. Although the chosen bootloader (or lack of) can force the user to set things up in a particular way. So in my opinion the term is best avoided.
grub-install always installs most of GRUB (modules, fonts, themes, files for localization, etc.) to the /boot directory, regardless of target, and regardless of which partition holds the contents of that directory —unless said partition contains a filesystem type that GRUB doesn't support reading from—.
The rest of it depends: on UEFI systems, grub-install additionally installs a PE32+ file to the EFI System Partition. Which can be mounted wherever you want as long as you tell grub-install where it is. Although three choices are the customary ones: /boot, /boot/efi and /efi. The Gentoo Handbook currently favors the latter.
On BIOS systems and disks with a GPT, grub-install additionally installs part of it to the protective Master Boot Record, and part of it to a partition marked in the GPT with a special Partition Type GUID.
On BIOS systems and disks with a MS-DOS partition table, grub-install additionally installs part of it to the Master Boot Record, and part of it to the space between the MBR and the first partition —which must be large enough—.
Oh, and you usually don't need to tell grub-install which system it is: it does a decent job guessing it and figuring out what to do. I. e. --target is not generally needed.
