Hi,

I have restored a W2K3 Server image using BartPE and imaging utility ShadowProtect.

I can see the volumes fine in Bart.

When I try to restart and boot into the OS via Bart, does not work. Get a bunch of errors:

Warning: Unrecognised partition table for drive 82. Please rebuild it using a Microsoft compatible FDISK tool. (err=14)

If I try
find /ntldr
Only seems to find the bart installation
(hd0,0)

However traditional nt boot floppy loads the W2K3 server fine.

Suggestions on how to troubleshoot would be appreciated.

Thanks

VW

I understand you stated like that,
You have 1 hdd with 2 partitions(A & B ), on A, Bart exists with using Grub4dos and on B, there is nothing.
You did restore 2k3 on B.
Is that right?
Did you rewrite your boot.ini for 2k3?
and you should use "find (hd0,0)/ntldr" command instead, I think.
Can I ask some questions?
Which one is primary partition and active? and is there ntldr on B? Which command you use in grub to call on B?

Regards,

@yahooUK
I guess I should have explained my scenario with a bit more detail.

I am running Bart off a USB key and that is the only "disk" that Grub can see (hd0,0)

The computer actually has 4 disks in it. Disk 1 is where I have restored the 2k3 image, the other 3 disks are blank so I don't see that they're relevant.

Did you rewrite your boot.ini for 2k3?

I did, and I then copied that boot.ini to my floppy boot disk so the boot.ini is obviously correct.

and you should use "find (hd0,0)/ntldr" command instead, I think.

That command finds my USB key. For some reason so far Grub cannot see the 2k3 image. I think that the error message being reported is significant because I have restored other 2k and 2k3 images to this server without issue in the past. What may be relevant is that the original system had a Dell diagnostic partition which for some reason Shadow would not image. So I left it as I did not think it was important.

On the destination system I modified the boot.ini accordingly and set the C: partition as active. I would have thought that should work OK.

Can I ask some questions?
Which one is primary partition and active? and is there ntldr on B? Which command you use in grub to call on B?

C: volume is active

There is ntldr on the partition

Regarding the command that's the problem, I can't find ntldr on B, so I don't know what to do next.

Cheers,
VW

"Drive 82" should mean that you have three disks in that machine:
First disk -> 80h -> 128
Second disk -> 81h -> 129
Third disk -> 82h -> 130

What do you mean by :loleverybody::

When I try to restart and boot into the OS via Bart, does not work.

When exactly the error you describe comes out?
Is it in GUI, a BSOD or what?

Can you post more details, as yahouuk asked and a description of hard disks, partitions, their sizes, their filesystems?

Was the image comprehensive of MBR (and hidden sectors) or you re-built them?

Also get HDHacker:
http://dimio.altervista.org/eng/
save both MBR's and bootsector's, zip them together and attach the zip.

@jaclaz
The error message in Grub is
Warning: Unrecognised partition table for drive 82. Please rebuild it using a Microsoft compatible FDISK tool. (err=14)

Is it in GUI, a BSOD or what?

I cannot get Grub to start the 2k3 image, so there is no BSOD or anything.

Using an NT boot floppy, 2k3 image starts fine.

Was the image comprehensive of MBR (and hidden sectors) or you re-built them?

Yes

Also get HDHacker:
http://dimio.altervista.org/eng/
save both MBR's and bootsector's, zip them together and attach the zip.

I'll get back to you with this in a day or so, the system in question is remote to me at the moment.

Thanks

VW
