Hi all!

[... a notebook that can natively only boot from hard disk...]

I succeeded.
My steps:

-install grub on a spare disk
 -pay attention to 1) stage1.5 should be for FAT
                   2) stage1.5 should go to the place after the mbr
                   3) where did you left stage2?
-stage1 is now configured to read stage1.5 from track0 (of by one
 sect.)
-stage1.5 does now know how to find stage2 (partition and path)

-get the MBR of the target disk
-copy stage2 to the target disk (beware of the partition and path)

-get the MBR+stage1.5 from the spare disk (put it into an image file)
-now IMPLANT the partition table from the MBR of the target disk to
 the image we just made
-copy the image to the beginning of the target disk
-pray and reboot (-:


What you need: a working network to the notebook (for file transfer).
And tools to read and write directly from/to the disk.
A hexeditor on the helper machine is good. Some fdisk-alikes ar good
for verifications.

I append my image file: it (i.e. stage1.5) will look for "/stage2" on
(hd0,0).


Bye,
        Rob
