Is cygwin responsible for "ntldr is missing"?

[Mike Gerard]

Last night I uploaded, installed and ran the cygwin X11 server
on my home computer (Windows 2000 professional). All fine (except
that inside cygwin my Swiss-French keyboard was not treated
correctly). When I shut down cygwin was still running, so I
let the shutdown process kill it.

This morning I cannot reboot my system: "ntldr is missing"
all the time. I am inclined to think that it must be related
to cygwin. Maybe cygwin plays around with the partitions.

Anyway, how to recover the situation?

Thanks for any help,
