I've followed the instructions in the Gentoo Handbook and got to the stage where I reboot. However, once I select my system with Grub2, it just shows: loading *kernel*
loading *initialramdisk*

Any suggestions on what I should do?

Edit: I use the file system layout described in the handbook with one key exception because I have a BIOS system: I don't have a EFI partition.

The best advice is to use IRC: chat.freenode.net and /join #gentoo for live support from some very knowledgeable people.

First thing that comes to mind: make sure you have the modules required to access your hard-drive (FS, scsi, mobo controller) built-in to the kernel (ie Y, not M). I usually build in the main ethernet card as well so it always come up as eth0 (not that I have more than one anyhow. I just prefer having net whenever I reboot, irrespective of how.)

Mobo controllers tend to be the one, ime; but you only need the one chipset. lspci -k from live-disk will tell you what it's using.

People often forget scsi, but practically everything goes through that layer nowadays.

Can you please post a little more information about the procedure that you used to install? Did you use genkernel or compile your own? Are you seeing a kernel panic, or does it just hang? You should be able to boot a live CD and get back into your environment by chrooting following these instructions:

I compiled my own kernel. The system hangs, and I tried chrooting back in from the live cd to recompile the kernel. It still didn't work.

I use a MBR-style hard drive, because I wasn't sure if my system could support GPT.

You can try first installing it with Genkernel.
I also ran into the same problem where my kernel will not load.
I reinstalled Gentoo with Genkernel and it at least got my system booted.
After about 1 month, I switched over to a manually configured kernel.

I guess what I trying to say is that you should
try Genkernel if the manual kernel is not working out, get to know the system,
then attempt to use a manual kernel. :)
