repair Vista Boot

The other day after installing Windows XP into my system over Vista, the Vista boot manager menu is no longer appearing. So, I write a DOS batch file called nt60repair.bat:-

@echo off

color a

echo Run DAEMON first...
pause

echo.
echo Load vu5384.iso ....
pause

d:
cd boot
bootsect /nt60 c:

echo.
echo Vista Boot Manager repaired...
pause

Because vu5384.iso, a Vista beta, is to be used for repairing, a virtual CDROM utility program has to be first installed and loaded it. This way I don't have to reinstall Vista.
