[gentoo-user] GRUB isn't working on SSD

Dear list,

After finishing the configuration, my gentoo was working very well. So, the
last step was to create a stage4, and replace my old hd.

I did it, installed grub lecacy in chroot. No error reported during the
installation. My /boot isn't a separated partition, and my root fs is ext4,
just like before. Everything is the same but the ssd.

I tried the grub2, but I had the same result. I don't think grub is the
problem, and I don't see need to change it, since I have just gentoo on my
machine.

what do you say?

olympus build # cat /boot/grub/device.map
(hd0)   /dev/sda
(hd1)   /dev/sdb
(hd2)   /dev/hdc
(hd3)   /dev/sdd
olympus build #

sdd is the boot ssd (mbr) - grub would not recognise it until this was set.

does grub find your ssd device at all?

You can find it in the grub shell using tab completion, it is
(hd<something>)

If you have the old and new drives now installed, grub's idea of device
numbers may have changed

Have you tried grub2-mkconfig -o /boot/grub/grub.cfg ?

Ah, you have a screen problem. Shouldn't be too hard to track down as
the only thing grub has available is what the bios provides.

My first step would be to double check your video settings in the bios,
then check if you have configured grub to run quiet.

I know my Ubuntu machines are all blank between post and kernel init
because Ubuntu sets it up that way for the "benefit" of the millions of
idiots running ubuntu. I can get a grub screen my pressing esc (or maybe
it is enter), this might be your trouble
