You done lost either your OS partition or your hard drive.

Run grub-rescue from a live linux cd, or repair from a windows install disc.

Your disk isn't configured to be bootable.

In windows:
Put your cd in
cmd.exe
diskpart
list disk (to get the disk number)
select disk #
list part
select part #
set active

You should install Gentoo and get an array of more avant garde errors.

OP needs to compile a custom kernel.

>>53785709
are you in fast boot mode?

if so, have you plugged/unplugged a piece of hardware on your computer? it may be the cause.

Hard drive dead
hope you have backups

It may be possible that your bios battery is empty so the bios reset and the wrong boot disk is selected. Google how to change the boot drive in bios, I'm not gonna explain it here.
