Installing PCLOS to hard disk with WinXP

[sling-shot]

I am trying to install PCLOS to hard disk hda10 partition from the live CD.

During the process i selected install boot sector (or something like it) to hda10 and not MBR (that is where Windows' is which should not be touched)

i followed a guide published on the net somewhere

4. Dump Linux boot sector to a file. Type the following:
dd if=/dev/hda2 of=/bootsect.lnx bs=512 count=1
If your linux boot partition is not in the hda2 partition, change if=/dev/hda2 accordingly (use df to get the correct partition).
For example, if your linux boot partition is in hda3, change the command to:
dd if=/dev/hda3 of=/bootsect.lnx bs=512 count=1

But i get "access denied" error even when logged as ROOT.

Any idea why this happens?

The reason for "access denied" error was not found. But i succeeded in getting the boot sector by booting into Puppy Linux LiveCD and now i am writing this from the finished hard disk installation.
