So, I used LVM for the root filesystem. At the first boot, GRUB gave me an Error 15. I checked out the documentation, and it says that it can not find a file (but it does not tell what file).

I think error 15 means it can't find one of the files specified for the specific entry in /boot/grub/menu.lst (i.e. it can't find the kernel or initrd, not that it can't find any grub-specific files).
Interestingly enough, I get the same error when experimenting with the persistent device naming patch, and there the problem is that the /boot/grub/menu.lst file is created with entries like "kernel /boot/vmlinuz-<kvers>" and "initrd /boot/initrd.img-<kvers>".
Changing them at first boot to "kernel /vmlinuz-<kvers>" and "initrd /initrd.img-<kvers>" is enough to boot.
Could you please verify whether this is the case for you as well? -- David Härdeman
