WinMe Boot Recovery

In an attempt to dual-boot I loaded the boot-loader XOSL on my WinMe box, which seemed to work fine… but the dual-boot didn’t work as planned so I thusly tried to remove the new boot-loader….
Did an fdisk /mbr… and was the greeted with a “missing operating system” error on boot. So I then tried the tried-and-true method of running “sys c:”….
No luck… same error…
What am I missing here? Is there some trick to booting WinMe that is different from 95/98?
