Dual Boot Oddity

[Guest]

Okay, first I tried upgrading XP Pro on my SATA hard drive. BSOD on last
reboot. Tried "repair" and got two choices (one Vista one Vista "repaired"),
both of which BSOD'd. Restored XP from image, booted to the DVD and
installed to the IDE drive (no Windows of any version, just a backup drive).
On last reboot, Vista loads, upgrades work, activation works, all is well.
Take out the DVD and reboot and straight to XP.

Hmmmm.... Put the dvd back in, reboot and DON'T "press any key to boot to
cd/dvd". Get the Vista & Vista "repaired" choices, where Vista works fine &
"repaired" BSOD's.

No big deal--I can just put the DVD in when I want to boot into Vista, but
does anyone have any idea what's causing this and what I can do to fix it?
In either system, looking in My Computer properties/Advanced/Startup &
Recovery options only shows that version as a choice for default. I could
manually edit the XP boot ini file if I remembered the context for the file,
I guess.

Sorry for the dupe--the silly web interface told me the first time that there
had been an error and closed, which sorta implied that it wasn't gonna get
there. I just didn't wait long enough for it to show up before retrying.

Again, my apologies.

Go into BIOS setup and swap the order of Hard Disk (Boot Priority).
Without the DVD, the computer is booting from the disk specified in
the BIOS. With the DVD, the computer is booting from the other disk.
