i need to convert my COMPUTER OS from Windows to DOS.
i TRIED it before just for fun, but it didnt work for some reason.
but now i really need to convert one of my computer OS from Windows to DOS.
i ran FDISK and resetted all the partitions and installed MS-DOS.
but some reason, it didnt work
did i do somethin wrong??
if ANY1 knos how to convert, plz help me out
thank youWhat are the specifics on the machine, which version of DOS and your technique?WARNING!!!!
THIS WILL ERASE ALL OF YOUR DATA!

Ok now that thats out of the way. If you just boot from a Windows CD or Floppy at the command prompt type this:
format c: /s

That will format your C: drive and copy all the files that you need to make it BOOTABLE to the correct locations. Then you can load WHATEVER software you need.

If you need to boot into DOS with out losing all your data I believe (it's been a while since I used this) you can edit the MSDOS.SYS file on your C: drive. Change the line BootGUI=1 to BootGUI=0. The computer then should boot to DOS without loading Windows first.thnx for the replys.
for GX_1, my computer is pentium 2, 550Mhz(I think), and MSDOS that i have is 6.22. There are so many bad sectors in hard disk, so im thinking about putting new one.
If i buy new hard disk, and put it into the computer, do i just install MSDOS? or ill have to set up the partition? i know very basic about DOS like how to make directory or format, like basic stuffs.

for frankjoshua, i think that wouldn't work, if i format my hard disk with /s command, what about the hard disk partition, would it be still for Windows? i'm gonna try your way and see what i get.

thank you all.If I'm not mistaken, there is a 2GB limit on the partition size for DOS 6.22. Also DOS must be the installed in the first physical partition on the disk otherwise DOS will not boot.

Just my 2 cents worth. 8-)hi
just few more questions on DOS experts....
my dad somehow did fdisk and reset partition so that OS can be MS-DOS.
i needed to run some program which works only on MS-DOS.
but when i run that program, it keeps on saying DOS error 4.
does anyone knows what this means?

also, after i changed my OS to MSDOS, i dont know why but files such as AGAPCMAL, AGDLDAEI, AHAGADEA, or AHAJADDJ came out with out .exe, or .com.does anyone knows what this is?

last thing is that, i looked up through internet, and there's something called DELPART.EXE, to change partition from FAT to MSDOS ones. does anyone knows how it works or how to get them??


thnx allWhy don't you explain IN DETAIL what you have done so far. Your description has been confusing.Here are the MS-Dos error codes. Error 4 might be caused by the Files= command in Config.sys. See here.

Delpart.exe is used in a Dos environment to delete NTFS partitions. See here.

Like others I need to know exactly what has been done on your hard drive e.g. following fdisk was format used :-? and what are the partition sizes :-?

Thanks
