What is the functional equivalent of the old "fdisk /mbr"
in XP?

I need to remove a boot sector virus from my computer,
the virus is called "Partition Magic 8.0". :-)
Seriously though, PM8 quietly installed a boot-loading
"overlay manager" on my hard drive. Unfortunately, this
conflicts with Symantec Norton Ghost when I boot from
the HDD.

"In the old days" (pre- Windows XP) if I was caught in
this situation I could simply run "fdisk /mbr" to replace
the infected boot sector with Microsoft's original.

So, what is the functional equivalent of the old "fdisk /mbr"
in XP?

Hi there atr!

Essential disk maintenance tools have moved to the Recovery Console,
which is available when you boot from the original XP CD. You cannot
actually change the MBR while XP is running.

Here's the Microsoft support article which describes how to access the
Recovery Console:

Once you're in the RC, use the command FIXMBR, which is the equivalent
of fdisk /mbr (it writes a fresh copy of the MBR).

I hope this helps! If anything's unclear, then please don't hesitate
to use the "request clarification" feature before rating this answer.

All the best,

Thanks for the fast answer.
