I had the same problem last night. I decided it was time to give my linux
setup a little more room, so I repartitioned the drive completely.
I removed all partitions, and used linux's fdisk to create a bootable dos
partition, and an extended partition containing a stackered dos partition
and 3 linux partitions (/, /usr, /tmp).
Then format c: /s /u and (try to) reboot: Missing Operating system.

I checked c:\: it did contain command.com, and the 2 system files.

I then tried to use DOS's fdisk to remove all partions: no dice. It
complained that a logical partition still existed in the extended, but
when I wanted to remove the logical partition from the extended, it said
there was no such thing. I just love MS-DOS. It can be _SO_ CONSISTENT.
[[check out 'dir *' and 'del *'...]]

So it left me with no choice but a low level format by means of the
AMI-bios setup harddisk utility...

That being done (took more time than I needed to eat my meal...)
format c: /s /u, and yes, it booted fine.

Then I used DOS's fdisk to create a partition table:
active bootable DOS,
extended partition for the rest, containing
small dos partition, to be stackered,
a lot of free room for linux.

That being done, I was still able to boot DOS, and went for Linux.
Linux's fdisk reported that my last cylinder was not allocated, but I
decided not to do anything about that (yet..., maybe some other time :-) ).
I created the 3 linux partitions as logical partitions in the free room of
the extended DOS partition, and installed SLS: no problems.

Everything is running fine now.

I hope this is of any use...

Good luck,
