[comp.sys.ibm.pc] HD partition and MS Windows

paine@fungus.dec.com (Willy Paine) (04/18/89)

After I change partition to split into two different operating systems
(Xenix/386 and Compaq Dos 3.31),  I can change active partition without
any problem and I can boot either system without any problem at all.
I notice that I can not run MS Windows/386 at all, even testing with
removing autoexec.bat and config.sys.  BUT if I boot Dos from floppy
disk, I can run Windows without any problem.  It appears that MS
Windows does not like mixed operating system HD partition???
 
Last Summer I had trouble with installing OS/2 in former Xenix computer
and MS told me to make low level format the whole hard disk.
 
How can I fix the problem with MS Windows?   Can you explain how HD
partition work?
