I might be wrong but I don't think you can FDISK a HDD
without creating a primary partition. However this isn't
a problem as far as your drive assignments go as you can
re-assign the drive letters in windows to be whatever you
want. The only place that the drive assignments would be
mixed up is in true DOS which will assign them in the
order C:=HDD1-Primary1; D:=HDD2-Primary1; E:=HDD1-Extended1;
F:=HDD1-Extended2; G:=HDD1-Extended3; H:=HDD2-Extended1; etc.

You will need to FDISK, make active and format the new
replacement HDD to make it bootable (see Tech Bulletin #10
for the details). After that, you need to transfer the
OS from your backup drive to the new C:. Since you'll be
operating in true DOS, you won't have long filename support.
Although you could do the recovery with a bit of fiddling
around, I think you'd be better off doing the following:

1. Make your backup drive a bootable clone using the steps
in Tech Bulletin #10 except that it would not be set as
active.

2. Re-assign the drive letters in windows to the configuration
you want.

3. If you need to replace the original HDD1 drive:

3a. Remove the original HDD1 drive
3b. Put HDD2 into the HDD1 IDE0 slot and the new HDD3 into
the HDD 2 slot.
3c. Boot to DOS and partition and format HDD3
3d. Make HDD2 (backup drive) partition 1 active
3e. Boot to windows (on HDD2) and clone HDD2 to HDD3
3f. Swap IDE cables and make HDD3 (in IDE slot 0) partition 1
active
3g. Boot to windows and you should be done

Depending on your motherboard, you might be able to eliminate
the IDE cable swapping by setting the boot drive in the BIOS
which would make things easier. Also, I think some versions
of FDISK will allow more than one HDD to be set with an active
partition (not 100% sure on this).

Note: I haven't actually carried out this operation but I
think I've got it right. Others who are still using W98 may
be able to add something further.
