I am running Virtual PC 2004 on a Win XP Pro system.  I
installed Win2000 without any problem, but Win98 has
humbled me :-(  Since I am builing from scratch I was
able to try many different configurations (EX.  WinXP
booting from the C: Drive using both NTFS and FAT32 and
booting from  a different drive leaving the C: drive
formated with FAT32)  I am using a Win98 boot disk in
drive A: and Win98 CD.  I have also tried capturing a
Win98 ISO image and the A: Drive.  I have tried setting
the hard drive as virtual and pointing it to the C: drive
as physical.  The typical result has been that when I run
the virtual machine it boots from the A: drive, but
reports that there is no C: drive available on the
system.  The ramdrive is created as the C: drive and the
CD rom is available.  For a brief period of time, for
reasons unknown to me,  The C: drive was visible.  When I
started the Win 98 installaion it ran scandisk and
reported that every thing was okay, but when Win98 began
to install it reported a severe hard drive error and
stopped.  At that time WinXP was booting from the F:
drive with an NTFS format.  

I apologize for the length of this post, but since there
doesn't appear to be much documentation I thought it
would be best to give the details.

Any help will be greatly appreciated.
