Fix for 2 Boot Menus When Dual Booting With Another OS

Filed under: add to del.icio.us

This will get you down to only 1 boot screen.

It is really easy: On my system my main drive has two partitions. One for XP
and the other for Vista.

My XP installation is on C: and my Vista installation is on F:

I copied the F:\Windows\System32\winload.exe (Vista Installation) file to
C:\Windows\System32 (XP Installation)

Then I edited the boot.ini file as follows:

Original boot.ini:
[boot loader]
timeout=10
default=multi(0)disk(0)rdisk(0)partition(1)WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)WINDOWS=”Microsoft Windows XP Home
Edition” /FASTDETECT /NOEXECUTE=ALWAYSOFF
multi(0)disk(0)rdisk(0)partition(2)WINDOWS=”Microsoft Windows Longhorn”
/NOEXECUTE=ALWAYSOFF /FASTDETECT /USENEWLOADER

New Boot.ini:
[boot loader]
timeout=10
default=multi(0)disk(0)rdisk(0)partition(1)WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)WINDOWS=”Microsoft Windows XP Home
Edition” /FASTDETECT /NOEXECUTE=ALWAYSOFF /USENEWLOADER
multi(0)disk(0)rdisk(0)partition(2)WINDOWS=”Microsoft Windows Longhorn”
/NOEXECUTE=ALWAYSOFF /FASTDETECT /USENEWLOADER

As you can see I just added the /USENEWLOADER switch to the XP Installation.NOTE: Doing this may cause a code 10 error with Asus SCSI cards using LSI53C875 drivers. - Thanks Scott for the info.
