[ltp] Using winXP and Ubuntu

[JS]

I have installed winXP followed by Ubuntu on my T40/p

But when I run:

sudo fdisk -l

from a shell I get:

Disk /dev/hda: 80.0 GB, 80026361856 bytes
16 heads, 63 sectors/track, 155061 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

Device Boot Start End Blocks Id System
/dev/hda1 1 60945 30716248+ 7 HPFS/NTFS
Partition 1 does not end on cylinder boundary.

/dev/hda2 60946 142832 41270985 f W95 Ext'd (LBA)
Partition 2 does not end on cylinder boundary.

/dev/hda3 * 142832 155056 6160927+ 83 Linux

/dev/hda6 142227 142832 305203+ 82 Linux swap /
Solaris

I have heard that I could just ignore this error, but
that is not correct since it also messes something up
in winXP. Eg when I try to use Partition magic to
resize my NTFS partitions the program just exits with
an error. (this did not happen before I installed
Ubuntu).

I have tried to disable the PreDesktop Area option in
BIOS and then make the first partition with winXP
CD-ROM. I make sure to leave som space left which I
use for the Ubuntu installation. When installing
Ubuntu I just choose to use the free space and the
installer takes care of the rest.

Any ideas on why I get this critical error?

I have used the above procedure one a lot of machines
when installing Ubuntu and winXP without ever
encountering the fdisk error.

Hope someone can help!
