1 If it's a similar laptop I assume you have grub2 installed in EFI mode.
2 Check if you have grubx64.efi in your EFI partition (usually /<mounted EFI
3 partition>/EFI/gentoo/).
4 Also check if you have efi boot entry for grub with efibootmgr utility. if
5 grub-install with EFI target was used on a new system it should call
6 efibootmgr to add a Gentoo entry in UEFI).

8 If you are trying to install grub in legacy mode then look in UEFI settings
9 if CSM or legacy boot is enabled. But since you have win11 and you want
10 dual boot I don't think that it's what you want. Os-prober will not pick up
11 EFI win11 installation if grub is installed in legacy and you can't install
12 win11 in legacy since Microsoft made win11 UEFI-only.
