I am receiving a "Missing Operating System" error message when booting my Compaq DeskPro M series computer.  I have a drivespace compressed Conner 340 mb hard drive and am running the windows 95b operating system. I do not have a compressed disk backup system disk, only an uncompressed copy made before running drivespace.

I would like to reformat the harddrive and start over.  The following responses were received while trying to reformat the drive (after booting with the uncompressed boot disk):

format c:   Drive C is a compressed drive.
               Use the Drivespace tool to format the drive.

drvspace format c: This program requires MS Windows

scandisk /all  This version of MS Scandisk will work
                  only with MS-Dos Versions 5.0 & later

a: uninstall  file C:\IO:DOS is missing or invalid
                 file C:\W95undo.dat is missing or invalid

Please advise.

Boot with your Win95 startup disk or boot disk, then 'Fdisk' and delete your primary dos partition, and create new one before your format.

Also, be sure to have your CDROM's driver file available for the new installation.
Let us know if you need help with setup.

Thanks for the help. I got into this problem when I partitioned and formatted my hard drive before I added my Compaq diagnostics and setup partition.  When I tried to add them later, the computer responded that it needed space reserved at the beginning of the hard drive for these files.      

I have now reloaded everything, starting with the partition and files needed for diagnostics, followed by the dos partition and the formatting of the drive, and then loading operating system and application software.
