Booting from DOS **urgent**

you did not tell ur Operating System!!!

I have Windows XP Professional

In XP, u can't
It can be done in Windows 98 but not in XP!

But u can install DOS on ur system separately and then can boot into DOS, but u can't open windows XP from that!

You can make bootable disc by nero. then u canboot ur comp through it and start dos. u r wrong Vishal Gupta.

there is another method while turning on ur comp hit F8 button repeatedly. u 'll see a boot menu. then u can start command promt

^^
1.) Thats not DOS, its Recovery Console.
2.) vineet wants to start DOS and from DOS he wants to start windows XP. Thats not possible in Recovery Console!

And no need to boot using XP CD to just use that DOS (Recovery Console), which u r talking about, u can install it on ur Hard disk, just start windows and insert ur XP CD and open the I386 folder and give following command in addressbar:

winnt32 /cmdcons

Firstly, why do you want to boot into DOS?

Thanks for you suggestions.I will use a bootable disc.But ,is there anyone who can solve my second problem related to c++.
