Not creating the recovery disk set prior to making these changes was not a
good idea. When you installed XP it overwrote the mbr to point to XP's
bootloader instead of the proprietary boot manager that HP uses for their
Recovery Manager software. You will likely need to contact HP support about
how to access it (normally done by hitting F11 at startup).
If you install x64 to the Vista partition, programs will not be migrated as
this would not be an upgrade but rather a clean install. It would, however
alter the mbr once again and give access to both installations. Data from
the existing installation would be preserved in a windows.old folder
provided you do not format as part of setup and sufficient space is
