You don't provide enough information about your /boot, fs layout, etc., so it is difficult to know why the new GRUB2 failed to work. As a rule of thumb, if GRUB2 had worked before the likely problem is file corruption, or forgetting to run grub-mkconfig after you made and copied over your new kernel and initrd - it depends on what the message was when it failed to boot and what file it couldn't find. I'd run fsck on the /boot partition to make sure there is no fs corruption and hdparm on the disk would be advisable too. > I've reinstalled > using the grub-mkconfig command but have not reinstalled using the > grub-install command.

Also, I need to let my hair regrow a bit. ;-) Take a look at this page to make sure you don't remove some GRUB file needed for a boot: https://wiki.gentoo.org/wiki/GRUB2_Migration There are other GRUB related pages in the wiki to help with configuring GRUB2. BTW, you don't need the old legacy GRUB as a fall back to boot your system. You can use a LiveCD/DVD/USB and you can configure your GRUB2 to boot this from your /boot, or some rescue partition on disk. Of course, if GRUB or your /boot fs/partition is borked, then a LiveUSB is always handy. ;-)
