My friend's pc has two hard drives installed dual-boot on his dell pc. Both hard drives are windows xp. On the boot loader, they are listed as:

"Windows XP professional"
"windows XP professional"

Now, the frst hard drive caught many viruses and he was thinking of doing DBAN, and install windows XP all over again on the first hard drive. But he's curious about what will happen to the boot loader. Will the boot loader update somehow after he does a clean wipe of the first hard drive? Will it make a mistake such as list three different OS on the boot loader? Sorry if this sounded like a dumb question, it's just he wants to make sure if he can do a clean wipe on one of the hard drives without affecting the boot loader in some way. What he would like is if the boot loader will still load the exisitng 2nd hard drive (the good one) with the new installation of the first hard drive. So, is it safe?

If you overwrite the hdd, there will no longer be anything there, it will be a blank unpartitioned hdd.

O ok. So let's say if I dban the first hard drive, then restart, will the boot loader load only the other hard drive with XP?

It should look for the hdd with a operating system. To ensure this occurs, make the hdd with the operating system the first device in the boot order of the BIOS.

O ok. My other question is, what if I dban on the first hard drive, then reinstall windows XP on the first hard drive, will the bootloader remain unchanged as how it would show in the boot loader?

The MBL will be in whichever hdd has the operating system installed in it.

O ok. The reason I ask is because I want to make sure I don't remove the boot loader. I'm not sure in which hard drive the boot loader was installed. But by all means, the XP that boots first (the first hard drive though) in the boot loader is the one that's infected and needs to be DBAN. I want to DBAN it and then reinstall XP and make sure that there will be a boot loader, or in better words, both XP installations from each hard drive show up for me to be able to choose. I don't want to lose the option from choosing between both hard drives.

UPDATE: I just remember that the boot loader is coming from the second hard drive that's not infected. I assume that if I dban the first hard drive, the boot loader will still persist on the second hard drive. But what I'm curious to know is if I do a full wipe (DBAN or killdisk) and then reinstall xp again on the first hard drive, will the boot loader from the second hard drive recognize the new installed XP from the first hard drive? Or will the boot loader jump to the next hard drive?

When you say boot loader, are you referring to the Master Boot Record?
