how can make load dos program in my c drive,i've no need of os because that program used by me it run on DOS

Answer 1

i can't understand your question because of your grammar

Answer 2

At the C: drive
do a make directory (to create a folder) like
md Jim (or whatever you like, 8 letters or shorter)
then cd Jim (prompt willl look like C:\Jim>
copy your programs like Copy D:\*.* C:\Jim
which means copy all of the D: drive to the Jim folder
to run, go to that folder and run the program like
C:>
cd \Jim
C:\Jim>
C:\JIm> start.exe (or whatever the program is.)
