I want to make a tiny partition from C drive and install DOS (only DOS / Linux / Free DOS just for booting purpose) in that partition, programmetrically. I want to make it first in boot sequence.

I am using XP SP3 / Win7 32/64 bit. I know VB.Net. How to do that?

u can use diskpart.exe to create the partition.
start with creating the diskpart script with relevant information.
example:
            string partitionLetter = "Q";
            StringBuilder sb = new StringBuilder();
            sb.AppendLine("SELECT DISK=0");//Select the first disk drive
            sb.AppendLine("CREATE PARTITION PRIMARY");//create new partition
            sb.AppendLine("ASSIGN LETTER=" + partitionLetter);//assign letter
            sb.AppendLine("FORMAT FS=NTFS LABEL=\"TPS\" QUICK");//format new partition
            sb.AppendLine("EXIT");
            File.WriteAllText(@"c:\temp\part.scr", sb.ToString());//create diskpart script
            Process.Start("diskpart.exe", @"/s c:\temp\part.scr");//run the script

Open in new window

In exe path i.e. debug folder. When I will make the setup, it will be in the software setup, I guess

i don't think u can silent install freedos on your HD.
follow this steps from this website which requires no bootable or something like that.
http://marc.herbert.free.fr/linux/freedos_no_removable.html

download this installer from here: http://marc.herbert.free.fr/FDOS/beta9pre5/
once unzip the installer, goto FREEDOS\SETUP\INSTALL\INSTALL.EXE and run it.

DiskPart.exe should be located here:
C:\Windows\System32\diskpart.exe
the following OS should have it: Windows Vista, Windows® XP, and the Windows Server 2003® family:

As suggested by you I tried with the following code in VB.Net

Imports System.Text

Public Class Form1

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Try
            Dim partitionLetter As String = "Q"
            Dim sb As StringBuilder = New StringBuilder()
            sb.AppendLine("SELECT DISK=0") 'Select the first disk drive
            sb.AppendLine("CREATE PARTITION PRIMARY") 'create new partition
            sb.AppendLine("ASSIGN LETTER=" + partitionLetter) 'assign letter
            sb.AppendLine("FORMAT FS=FAT32 LABEL=""FD"" QUICK") 'format new partition
            sb.AppendLine("EXIT")
            System.IO.File.WriteAllText("c:\part.scr", sb.ToString()) 'create diskpart script
            Process.Start("diskpart.exe", "/s c:\part.scr") 'run the script
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try

    End Sub
End Class

But I am getting error. I tried from command line also. I am attaching the screen shots here

the instructions given depend upon the fact that there is in fact unallocated space on the hard drive or that it is a blank hard drive.

I would greatly suggest that you use a virtual machine to test things. dosbox comes immediately to mind

Dos / linux booting is pretty much foreign to modern operating systems and they require their own boot loader i.e. grub.  so now we are into a multiboot situation.

Since windows 7 is in the mix... then we are dealing with the bcd store. suggest you become familiar with the workings of easybcd http://neosmart.net/EasyBCD/  and look at how he handles the multiboot situation.

Dos boots from the first active partition and that partition MUST not be NTFS .. I think freedos only understands fat and maybe not even fat32 partitions.

This is a a fairly involved project and not something that I'd suggest a novice to cut his teeth on.
