Re: GRUB2 fails when booting from CD

[Phillip Susi]

It sounds like you built the iso to use hd emulation instead of native
el-torito boot, and you don't have the correct modules built into the
core image.  Either that or if hd0 actually is the hard disk and not an
emulated one, you don't have the partition table module built into the core.
