suddenly my Gentoo box does not boot any more. It halts after Grub

I booted from a rescue stick and chrooted into the system. I manually
ran grub-install to the SSD and grub-mkconfig to the boot partition without
success.
Does grub need busybox?
No.
What is wrong or what is missing when the box halts after writing "GRUB "?
"GRUB " is written by GRUB boot image, usually located in the MBR. Then
it should load GRUB core image which should write "loading". The core
image is usually located in sectors next to the MBR in MSDOS scheme MBR
or in a dedicated BIOS boot partition on GPT scheme. It can also be
located in a plain file /boot/grub/i386-pc/core.img but this is
discouraged because using block lists with a file is unreliable.
How can I get my box boot again?
You can run bootinfoscript and check if GRUB is properly installed.
