Dual-Boot Missing?

[Guest]

Hi,

A week ago I had XP and Vista on seperate HDDs (using a dual-boot setup).
This weekend I decided to format XP HDD and install clean XP again. (needed
doing). However, now when I boot up my machine, it automatically loads XP
with no options. Vista still exists on the seperate HDD. I've also arranged
boot-up preferences > CD/DVD then > HDD etc... (in same order as before).

Any help?

Cheers,

Boot with your Vista DVD. There is a 'Startup Repair' option that will
rebuild the Vista boot files. Can't remember offhand how many screens one
has to go through to get to it though.

You over-wrote some necessary boot files that Vista installed and used on
your XP partition (in a dual-boot scenario). So Vista no longer exists in
the boot sequence. You will have to re-install Vista so that it can re-write
this information.
You could first TRY booting from the Vista media, and doing a "repair
start-up", but I really don't know if this will help in your
situation--maybe somebody else knows.
PS. when setting up a dual boot, it is almost always imperative to install
the newest OS last.

Startup Repair has worked for me after I had to do the same as the OP ;-)

When you formatted the drive you wiped out the boot configuration data store
that Vista needs to boot. The BCD store is written to the root of the boot
system drive of the first operating system installed on the machine. You
can try running VistaBoot Pro 3.1 from XP and choose the option to rewrite
the BCD store.
