where is grub-reboot or something similar as "lilo -R"?

Sounds like you want the fallback parameter (see the grub info file).
If whichever entry as your default doesn't boot, it tries the fallback
one.  They both use a number as a parameter, so if your default was 1,
try your default as 2 (the next oldest one).

I'm not sure if this'll do the trick, though.  It depends on where the
failure happens:  If GRUB isn't able to find something to start booting,
I'd expect it to take action.  If GRUB has tried to boot a kernel, and
passed over to it, and the kernel fails to load, I wouldn't expect GRUB
to do anything about it.
