Hello I have a Pc,WinXP was setup on the first partition,formated NTFS.I have some program run in MS-DOS and i have already install MS-DOS at the second partition,formated FAT32.But i dont know how to config my windows so that when the PC boot,there 2 choices for me,boot to Win and boot to DOS.Former time,when i have already bought the PC,they do that for me but i dont know how they do.Pleasy help me.Thanks so much! -------- jinajinajinana How to create a multiple-boot system in Windows XP http://support.microsoft.com/kb/306559/en-us Install the operating systems in the following order: 1.

To do so the second partition (where MS-DOS is installed) would have to be marked as active, you can check or do that with FDISK. Which partition are you you booting with now, which operating system starts when the computer boots?

Boot to your Windows XP installation and from the command prompt run the Debug command to create a boot sector file for the DOS installation on the second partition. You can run these commands at the debug screen, but an even easier way is to just copy them to a file and have debug run them automatically. Copy the stuff *between* the === lines and save it in a notepad file as READ.SCR, save the file in an easy to find and navigate to directory, the root folder of the XP installation drive (C:\) is as good a place as any other: READ.SCR ============================================ L 100 3 0 1 N C:\BOOTSECT.DOS R BX 0 R CX 200 W Q ============================================ Now, start a command prompt session and navigate to the folder where the READ.SCR file is located and issue the following command: debug <read.scr This will create a C:\BOOTSECT.DOS file from the boot sector of the DOS installation on partition 2. For this file to work Windows XP must be installed on the first partition and DOS must be installed on the second (D:\) partition of the same disk. Verify in the root folder (C:\) of the XP NTFS drive to make sure that the newly created bootsect.dos file is present, it will be in the root folder along with the hidden system files ntldr, boot.ini and NTDETECT.COM. Now edit the boot.ini file and under the [operating systems] section add an extra line for the DOS installation: c:\="DOS" The boot.ini file will now look something like this: [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect c:\="DOS" You should now be able to boot the DOS installation on the second partition. If it doesn't work post again and we can try another slightly different method of arriving at the same goal.

I followed, but it say these: --------------------------- 16 bit MS-DOS Subsystem --------------------------- C:\WINDOWS\system32\cmd.exe - debug An application has attempted to directly access the hard disk, which cannot be supported.

Toggle the active partition and boot to your MS-DOS installation and run these debug commands to create the Bootsect.dos file: L 100 2 0 1 N C:\BOOTSECT.DOS R BX 0 R CX 200 W Q The file should be created in the C:\ root of the DOS installation. Use the debug command to verify that the file you just created is for the MS-DOS installation: At the DOS prompt enter the following debug command: debug c:\bootsect.dos Then at the debug prompt enter: d 100 L 100 this will allow you to see the beginning of the bootsect.dos file. The first bytes should read MSDOS... Then at the debug prompt enter: d 200 L 100 you will now see the second half of the file, the last bytes should read IO SYSMSDOS SYS. Now, toggle the active partition again and boot to the Windows XP installation. Copy the bootsect.dos file that you created to the root of the XP inatallation alongside the ntldr, NTDETECT.COM & boot.ini files. Edit the Boot.ini file and under the [operating systems] section add a line for the MS-DOS operating system: c:\bootsect.dos="MS-DOS" Now, with the Windows XP partition set as active try to boot to the DOS installation. If it doesn't work don't despair, we can transfer the XP boot files to the DOS partiton and change the boot sector to boot the operating systems from that partition instead of the XP partition. John Brother,are you still there? Sorry that these time i didn't online because the IE have problem,cannot logon(seemed there's a risk in my PC and it shutdown my IE usually,so save..) Come back with my MS-DOS problem,i followed ur way,boot to MS-DOS partition and use that command but cannot run.It say bad command line.So,can i use MS-DOS beside Windows in these case?Is it able or not able.....? Hope you come back and help me soon,thank alot! --------------------------------------------------------------------------------------------- > > I followed, but it say these: > > --------------------------- [quoted text clipped - 62 lines] > > John While booted to DOS did you run this from the Debug Prompt? At the command prompt you have to start Debug first then issue the commands at the debug prompt. If this doesn't work our option list is becoming shorter, a bootsect.dos file must be generated for ntldr to use to boot the DOS installation. But there are still other options available...

If i mark DOS partition active then setup windows after then i will be able to do this thing(choose boot to win or to dos) but in that,the windows partition lettered F:(the end partition) and i don't want this thing. Ok John,brother,can u teach me understand the structure of bootsec.dos file ok? I feel so curious about bootsec.dos ja.Thank John,i hope will complete my problem soon. > While booted to DOS did you run this from the Debug Prompt? > [quoted text clipped - 87 lines] > > - Show quoted text - Debug is an ancient command that is included in almost all versions of MS-DOS, is it part of your DOS installation? If you can't create the Bootsect.dos file you will have to use a third party boot manager. Another way of creating the multi-boot is to start a Windows XP installation from the up and booted MS-DOS installation and then aborting the installation before the first reboot. When the computer reboots after the aborted setup select to boot to the MS-DOS installation from the boot menu and then clean up the aborted installation files and add a line to the newly created boot.ini file on the C: drive to point it to the XP installation on the other drive. To launch the XP setup from DOS insert the CD in the drive and navigate to the i386 directory and launch the Winnt command.

[quoted text clipped - 119 lines] > > - Show quoted text - Ok,thank you! > Ok,thank you! You're welcome. There is another way that might/should also work. 1- Create a boot floppy for the XP installation: Boot to the Windows XP installation and format a floppy diskette. The diskette *must* be formatted with Widnows XP, if it is formatted with Windows 9x/MS-DOS the boot diskette will fail to boot Windows XP. After the diskette is formatted copy the file ntldr, NTDETECT.COM & boot.ini from the root of the XP drive onto the diskette. 2- Try to boot to Windows XP with the diskette. Shutdown the computer, go in the BIOS and change the boot order so that the diskette is set as the first boot device. Insert the diskette in the computer and boot to Windows XP with it. 3- If you can successfully boot to Windows XP with the diskette, shut down the computer and change the Active partition to the MS-DOS partition. 4- Boot with to Windows XP with the floppy boot diskette. Even if the MS-DOS partition is the Active partition, (which it must for this method) you will still be able to boot XP with the floppy diskette. After the XP installation is booted you can use the Disk Management tool to verify the active status of the partitions, the MS-DOS must be the active partition. 5- Install the Recovery Console. While booted to the XP installation insert your Windows XP cd in the drive and in the Start Menu-> Run box issue the following command: d:\i386\winnt32.exe /cmdcons where d is the drive letter for the CD-ROM drive. This will launch the install routine for the Recovery Console. When the installation sees the MS-DOS FAT partition as the Active partition it will (should) create the necessary bootsect.dos file for the DOS installation and it should copy the necessary system boot files to the partition, create a proper boot.ini file for the operating systems and write the proper boot sector to the partition to allow it to boot the XP installation.

You're welcome Olicaca, thanks for letting me know the outcome of your efforts! John > 2 choices for me,boot to Win and boot to DOS. Just curious as to why you need to boot to DOS and/or a FAT32 partition. What do you need there that couldn't be achieved in a DOS shell? (Which I personally find way better than MS- or IBM- DOS ever was.) Also, I think IBM DOS v7 supports NTFS partitions. Ed I need use DOS for delete some files when i cant access it from Windows.I dont really understand your recommen aswell,sorry my English not well.Anyway thanks for the care. ------------------------------------------------------------ On 21 Tháng Ba, 01:35, "Ed Covney" <ed(dot)covney(at)gmail(dot)com> wrote: > > 2 choices for me,boot to Win and boot to DOS. > [quoted text clipped - 6 lines] > > Ed > I need use DOS for delete some files when i cant access it from > Windows You do not need DOS, you need to boot to anything but the windows drive you are targetting. If you can afford a 2nd hard drive, install Windows on it as well. Now you'll have 2 copies of windows on two drives on one system. (Hint un-cable drive #1, while installing windows on drive #2) Change the BIOS to boot from drive #1 or drive #2. While booted to drive #2, you can make any changes you want to any file or directory or drive #1 (and visa- versa). There are many other benefits to being able to boot to either drive 1 or 2.

Any hard driver bigger that 32Gb will more than likely be set to NTFS, which can not be accessed directly with most versions of DOS. All is not lost, there exists several "boot" CDs which will let you access all XP NTFS partitions so that you can manage the XP. I have a hiren't CD but it scratched all,cannot use and very tiresome that eachtime i need DOS will have to insert CD,not including that i live in the country, the way to the software shops far alittle .Anyway i want DOS on my harddisk aswell,must be have DOS,not discussion any reason.. :-C ---------------------------------------------------------------------- All is not lost, there exists several "boot" CDs which will let you access all XP NTFS partitions so that you can manage the XP.- Ẩn nội dung trích dẫn - > I have a hiren't CD but it scratched all,cannot use and very tiresome > that eachtime i need DOS will have to insert CD,not including that i [quoted text clipped - 10 lines] > > - Show quoted text - XP does not have a full dos. If you have an Internet connection and a CD/DVD burner, you can locate a XP emergency boot CD image and create a CD. |
