HELP!! /dev/root mount failure

[Hadders]

Okay,
  First off thanks to everyone for speedy replies. 

Secondly, I've solved the problem. 

The mkdevroot failure was a lilo problem. As soon as I went back to 
using grub, the problem went away and my Linux loaded, as expected. So I 
then immediately tried my old trick of "dd if=/dev/hda 
of=/tmp/linux_boot.img bs=512 count=1", to take a "snapshot" of the 
first part of the boot sector so my Windows disk could then refer to 
that in its boot.ini; c:\linux_boot.img="Core 5".....

However, this didn't work.

So, some more searching found that when using the NTLDR as your boot 
manager, you have to have the Linux AND the Windows partitions on the 
same disk, if you want to use grub.  But I know this is not the case 
with Lilo, as I've set up lilo for a second disk in the past without 
problems.....Windows on one, linux on another and Windows booting linux.

However, the key seems to have a separate /boot partition and to install 
your boot manager into that, NOT the MBR of the target disk. Then taking 
the 512 dd works....

So, now I've got Windows and Linux on the same disk, and Windows is in 
control of the MBR. I've always found this the safest thing to do, as 
I've had some bad experiences a few years ago. Admittedly, grub was 
young back then.

If anyone can confirm a working lilo-22.7 /etc/lilo.conf, that would be 
awesome, but in all honesty, I'm happier with grub as it's much nicer 
(/boot/grub/grub.conf, changes are less hassle)....
