I installed XP Pro on one hard drive. I then inserted the Vista disk in the
DVD drive and booted into the Vista installation and installed it on a second
hard drive. Installation went smoothly (or so I thought) except that after a
few reboots I noticed that the Windows Boot Manager never appeared giving me
the choice to choose Vista or a previous operationg system.
If I take the Vista installation disc out the machine will boot into XP,
with the disc in it will boot to Vista. Any ideas on how to get Windows Boot
Manager to recognize both operating systems?

Assumptions:
1. If the XP CD instead of the Vista DVD is in the DVD drive, the
computer also boots to Vista.
2. There was a change in the hardware configuration between the
installation of XP and Vista, such as the second drive being added
after XP was installed. Otherwise, dual boot should have been
installed..
Cause:
BIOS doesn't provide the correct information to Windows setup as to
which disk the BIOS is set to boot.
Solution:
1. Go into BIOS setup and switch the disk that the BIOS boots so that
the same OS is booted with or without the Vista DVD in the DVD drive.
If the First Boot Device, Second Boot Device, etc. setting allows only
Hard Disk to be selected, then the bootable hard disk is selected
under Hard Disk Boot Priority or Hard Disk Drives. If both drives are
SATA, their cables can be swapped so either XP or Vista boots.
2. If the OS that boots is Windows XP, follow the steps at

to create dual boot.
3. If the OS that boots is Vista, do the following to create dual
boot:
