I somehow botched my gentoo installation. After finishing the guide and rebooting, I had two new boot options thanks to efibootmgr, both "gentoo" because I accidentally used efibootmgr to create an initramfs entry of gentoo and one without initramfs. Both of which however only take me back to the boot entry screen after choosing them. Though somehow systemrescuecd's option to load your existing Linux distro is able to take me to my finished installation.

Since gentoo doesn't give me any errors when it tries to boot, just takes me back to choose what to boot from, I'm unable to see where the problem occurs, just that systemrescuecd seems to be able to circumvent it. After logging on to the system through systemrescuecd, is there any way to diagnose and fix the issue?

Yes, just load systemrescue again the way you did when you originally installed and chroot into the environment again like you originally did and redo whatever it is you did to create the boot loader and don't make any mistakes this time.

So basically, don't format any disks, that would mean a lot of wasted time, and just mount the drives and chroot back into it like you did the first time.

As a protip, you can chroot into any linux install from another install this way to fix whatever problems it may have to say repair the bootloader or alter settings or even install and de-install stuff. If you dual boot two installs you can chroot from one into the other and just use the package manager of the slave one to update that system if you want while running the other as a host.
