You can boot from a window rescue disk. If you don't see the C: drive
anymore, you probably corrupted your partition table (or you have just
hidden the windows partition). You can use linux's fdisk program to
fix it.
Otherwise invoke "sys c:" from the rescue disk. This should restore
the windows boot sector, as well as the windows boot files.
