trying to do, we could suggest other alternatives. For instance, if the<br>
disk is small, you could ddrescue it off to an image, dd that image<br>
onto a larger or same disk, and use that disk in another computer as<br>
sda.<br>
<br>
Or you could copy the Mandrake partition to a partition made of unused<br>
space on SDA, modify the /etc/fstab to either rename the devices, or<br>
better mount by UUID, and then add that partition to your current grub.<br>
<br>
I've seen things like you mention, where the live CD can boot only sda.<br>
And Grub really is a PITA.<br>
