I wanted to install gentoo along side arch. After i was finishd with the Installation and rebooted the was no Gentoo option. I tryed using the same Boot Partition as my arch installation. Any ideas how to fix that?

When you run grub-mkconfig it should find both arch and gentoo kernels/initramfs and make menu entries for them

Hi. Have you installed os-prober and added GRUB_DISABLE_OS_PROBER=false to your grub configuration?

i had same issue once, it was because the grub detects gentoo but boots the kernel of arch instead

#

try seperating the kernel and intel ucode img of both os, like keep them in differnet dir
