USB booting :: Help! DSL on USB stick, but grub got on HDD

You can mount the iso in Linux:
mkdir /mnt/iso
mount theiso.iso /mnt/iso -o loop

And then copy the files where ever needed..

Also, if you have a spare pendrive, you could just try "burning" the iso to a pendrive:
dd if=theiso.iso of=/dev/sda bs=1k

And then trying to boot from it..

But if you do give up, I think it's possible to make grub automatically boot XP.. Depends a lot if your XP is on NTFS or FAT32...

edit: it seems to me that your comp boots usb natively, and there are none grub files around....

Oh, I *like* the idea of burning the iso to the thumbdrive!

I'm not sure what you mean about no grub files around... the HD is NTFS. But should I just *make* some file for grub to access? If so, where should I put it? I think I understand how to build it, but I don't know where it should go.

I needed at one point to remove Grub from a MBR. What I did after trying various other stuff unsuccessfully was using MBRWork as found on UBCD; running the option "install standard MBR code". I can't guarantee this will work and you should probably back up your existing MBR first. But it worked for me.
