There are lots of instructions out there on how to dual-boot Windows Vista and Windows XP, but if you chose Windows Server 2008 as a OS of choice, things are a bit different. To simplify things for following installations of this kind, here are my notes.
- Install Windows Server 2008 and leave some free space for Windows XP partition
or
Make room for Windows XP. - Install Windows XP
- Boot into Windows Server 2008 installation DVD
- Run command prompt and fix Vista's boot records
C:
cd \boot
bootsect /nt60 c: /force
bootrec /rebuildbcd
(trick: "my" copy of Windows Server 2008 64-bit doesn't have bootsect.exe and bootrec.exe in C:\boot, so I had to run above commands from boot folder on DVD!) - Download EaysBCD, add Windows XP, reboot and you're good to go.
Point 4. is where Server 2008 and Vista differ. Painful, but it works.
