Hi, First, the scenario: I am trying to dual-boot Windows 7 with Windows XP Pro. Each is installed on its own internal SATA HDD, with XP being the older of the two OSes. However, when I boot my PC, it defaults to loading Windows 7, and does not present a Boot Choice menu. Easy BCD, installed on XP, cannot locate a BCD file, and when I navigate to Windows 7 (W>Windows>Boot>EFI (or PCAT) there is no BCD file to be found. I can find one under >Boot>DVD>EFI (& PCAT), and though I don't think this applies here I'll list what Easy BCD reports for them: DVD>EFI DVD>PCAT I don't have a 100MB "System Reserved" partition; the partition I'm looking on is definitely the one tagged "System" in Disk Management. I am now stuck and unsure how to proceed. Second, the history: I should provide some background to how I got to this stage as it involves live repartitioning of system drives, and a workaround for installing Windows 7. I began with XP Pro SP3 on its own drive, with a separate drive for data (ie. games). This has been functioning fine. I then purchased the digital download version of Windows 7 x64 Professional Upgrade from Digital River. I burned this ISO to a DVD, and booted from the resultant disc on startup (not by running Setup from the DVD whilst booted into XP). Following Paul Thurrott's advice here, I proceeded to clean-install Windows 7 to the first partition on a new (used) 80GB SATA HDD (the two other partitions consist of a swap-file partition for XP, and a backup partition for XP). Next came the partitioning: I booted into UBCD 5.0.2, launched Partition Magic and used Gparted to shrink the XP Pro SP3 partition to create space for a swap-file partition for Windows 7. And that's where I am now. If I leave Windows 7's HDD & XP Pro's HDD active in the BIOS, Windows 7 will load automatically on startup; if I disable Windows 7's HDD, Windows XP boots automatically. Obviously the stage I would like to get to is being able to leave both HDDs active in the BIOS, and receive the Boot Choice menu on startup. Can anyone help? Many thanks, S.
