I am following the steps in the C# OSDev series, except I am writing the kernel in C. I am using grub2. My directory layout:

Code:
.:
boot  kernel.bin

./boot:
grub2

./boot/grub2:
grub.cfg


Contents of grub.cfg:
Code:
multiboot /kernel.bin
boot


But I get a grub prompt when I run
Code:
grub2-mkrescue -o image.iso iso
and boot the image.iso.

Anyone have any ideas?

Is that all? Try this:
Code:
menuentry "Run my kernel" {
multiboot /kernel.bin
}

Grub2 looks for its configuration file in /boot/grub/grub.cfg (not /boot/grub2/grub.cfg).

Regards,
John.

Thanks!! That fixed it. I wonder why, but in Fedora 17 (what I currently run) the grub.cfg file is located only in /boot/grub2. The only file in /boot/grub is /boot/grub/splash.xpm.gz. Hmmm... Interesting.

The GRUB2 installer can take an argument to change the directory in which it looks for (some) things.
