How to restore previous Dual Boot

M

Mamoru Miura

Dear Sir/Madam

My PC has Win Me in Drive C, and I installed Win2000 in Drive D with keep
the C files.
Then, even seperatory installed, the boot screen never show the select menu.
So I manually add the following line in the file of 'boot.ini' of Drive C;

C:\="Microsoft Windows"

Yet the syatem said, when selected, Invalid System disk!.

Does any know how to solve this problem?

Thanks,

M.M.

You need a bootsect.dos file in the root of the C: drive, alongside the
boot.ini, ntldr and NTDETECT.COM files.

To create the file you will have to return the boot process to the
Windows Me operating system and then create the Bootsect.dos file, then
you will have to return the boot process back to the Windows 2000 boot
loader.

1- Return the boot process to the Windows Me operating system. To do so
boot with a Windows 98/Me startup diskette and at the A:\> prompt issue
the following command:

sys c:

Reboot the computer, it should now boot to Windows Me.

2- Create the Bootsect.dos file. Boot to the Windows Me installation
and use the ancient DEBUG command to create the file. Start an MS-DOS
Prompt and navigate to the root of the System drive (C:\) and issue the
following commands, pressing enter after each:

debug
L 100 2 0 1
N C:\BOOTSECT.DOS
R BX
0
R CX
200
W
Q

This will create the bootsect.dos file, verify its presence in the root
of the C: drive.

3- Return the boot process to the Windows 2000 boot loader (ntldr).
Boot to the Recovery Console with your Windows 2000 CD and at the prompt
issue the FIXBOOT command:

fixboot c:

The computer will now boot using the Windows 2000 boot loader. If the
boot.ini file contains a line to c:\="Description" you should be able to
boot the Windows Me installation.
