This is probably a problem with acronis software, but maybe somebody can
suggest something.

I have an acronis true image backup of a linux disk that has 3 partition:
compaq service (39mb), boot (104mb) and root (840mb) total of 1gb disk
(this is a solid state compact flash type disk, not a hard drive). I need
to debug a problem, but the core dump exceeds the remaining capacity of the
flash drive.

I tried reinstalling the backup on a larger disk, marking the /boot
partition as active, all the rest as primary. I tried various combinations,
all I can do is boot into the grub prompt. Not sure what to do afterwards.
I also tried acronis partition expert that allows partitions to be copied
and resized at the same time. Same problem, i boot into that GRUB> prompt
consistenly.

...TIA..

What is the compaq service partition -- a hidden compaq tools
partition?

What kind of disk -- hard drive?

Marking the partition as active means _nothing_ to Linux -- it's
strictly a windows gobblin.

What do you mean by "tried various combinations" -- just
guessing/hoping to find some magical way to "mark" the partition
_type_? Active? What tool?

What does tab completion offer? "find /boot/grub/grub.conf"? Where
and how is grub installed? MBR? Partition boot sector?

Have a look at the grub info pages for documentation -- it's pretty
complete, but sometimes concise and subtle ;-)

Not sure how grub treats your "disk device" -- hd0? fd0?
Try:
grub> cat /boot/grub/grub.conf

If you get errors whenever trying to access the fs this way, it means
stage1_5 file is not being located and you will have to use grub
notation to point to partitions -- eg., /boot would be called
hd0,1(first hard disk, second partition) and command would be:
grub> cat (hd0,1)/grub/grub.conf

See especially:

for help in "manually" booting from the prompt and here for list of

Thanks for the references below, I usually get as far as "man xxxx" and
anything beyond that and not found by google is an incantation AFAICT.

It appears my problems it that the disk I am duping the image on is a SCSI
and the system on the "acronis backup image" was built before the SCSI
controller was added. I edited /etc/modules.conf and added "alias
scsi_hostadapter aic7xxx" but it seems there is more to it then that. I see
the aix7 drivers in lib/modules... but it still fails to boot. I did go to
the acronis forum and posted much this same question and got no response
yet. I tried the latest version of true image (8.0) and saw a warning that
what I was about to do would require that I have a linux boot diskette
ready. It gave (acronis true image 8) instructions on working with lilo,
but not with grub. In any event I suspect the problem is the scsi
controller being used to boot a linux image that was built with no
controller present.

Thanks, I did some reading up on grub and was able to solve the problem...

At the GRUB> prompt I issued "find /grub/stage1" then (assuming it was
actually found there:YES!)
I specify "root (hd0,1)". This then allows the mbr to be created (i am
guessing about the technicals here) using "setup (hd0)".
Subsequently, you can reboot, the scsi controler is discovered and I have
now migrated to a larger linux (red hat 9) drive.
I also got some help from google for this else I would have no idea what to
do with those commands.

Good job ;-)

You basically did the "native" installation routine. Good to keep in
mind that you can always "re-install" grub in this fashion -- many
folks are too intimitated to try it without lots of hand-holding.

Keep up this kind of solve-it-yourself work and you'll have people
asking you for help;-)

glad you got it going,
