Using grub to boot: grub> find /boot/gnumach.gz returns (hd0,3) Based on the above I believe the root partition for the Hurd is: hd0s4 Is that correct? grub> kernel (hd0,3)/boot/gnumach.gz root=device:hd0s4 -s Later in the boot process I get the following error: start (hd0,3)/hurd/ext2fs.static: (hd0,3)/hurd/ext2fs.static: device:hd0s4: No such device or address If the root partition is correct is it possible that I am having a SATA problem? hal
