[kwlug-disc] Cloning old PATA to SATA (old system)

[William Park]

If I remember,

   - grub-install takes the whole drive /dev/sda not a partition /dev/sda1.

   - Ubuntu or Fedora (not sure which) has "rescue" entry or something 
in the boot menu.  It does bunch of "bind" mount, and put you in 
"chroot" environment.  From there, you can run grub-install.

   - Doing it manually,
	for i in /proc /sys /dev ... ; do
	    mount -o bind $i /mnt/$i
	done
	chroot /mnt

Clonezilla probably didn't clone, sector by sector.  If it did, then 
everything would be identical as old layout.  And, all you have to do is 
change "hda*" to "sda*".
