Impossible if it is formatted with NTFS, which is the most likely filesystem it is formated with.
Microsoft was never willing to give out info for their filesystem, so there is really no decent ntfs port avaliable for anything but windows. Linux have read supports now and some half decent experimental write support, but it is still very experimental and they say you can risk losing data if you use it with write support enabled.
I think you would have more luck if it was formatted in fat16 or 32 though, which is what win9x/me used.
But here is something similar to what others suggested: Get a bootable dos/win98 floppy disk with fdisk and type fdisk /mbr
This will recreate the bootblock"master boot record" on your hd. This has worked for me in the past when i managed to overwrite my mbr.
