The alternative technique of DOS in reload system

A friend of a computer installed http://www.aliyun.com/zixun/aggregation/13559.html ">windows 98 and Windows XP two systems, running for a long time the computer runs slowly, in Windows 98 often appear panic, window can not open and so on, so I asked to help him reload the system. After going to know his Windows 98 installed in C, Windows XP installed in D disk, and in D disk with Ghost made a Windows 98 mirror file. I can't help brainwave. Why not restore Windows 98 with a ghost mirrored file in pure DOS, and then repair Windows XP with the Windows XP installation CD? Wouldn't that be quicker? But another question has come up, in the dual system under how to use the boot disk or the installation CD to boot, in order to boot into the pure DOS? After trying I found that I could enter.

The specific operation is when the boot press DEL, into the CMOS, in the second BIOS Advance features in the boot set to filename after the F10 save, insert the boot disk Restart can be, if the CD-ROM, convert filename to CD-ROM. This is always a bit of a hassle, there is no faster way to enter the DOS? After my repeated groping, I found a way to get into DOS quickly without using any CD. To do this: when the dual system menu appears, move the cursor to Windows 98 and then hold down the CTRL and M keys at the same time, and you will find a menu that has access to DOS in Windows 98. Delighted when I saw the lovely dos, I quickly helped him restore Windows 98 and then repaired Windows XP with an installation disc in Windows 98, less than half of the time expected. After many experiments, it was found that this method is suitable for all Windows operating systems which are equipped with dual systems.
