I have the solution to install windows 2008 x64 (or vista) using 32-bit bartpe. here are the steps, i hope someone finds this useful. 1. Download the attached bcd file. If it is no longer available this is how you generate it: Install Windows 2008 x64, after installation grab c:\boot\BCD 2. Download Windows 2008 x86 32 bit iso 3. Open Windows 2008 x64 iso and extract install.wim 4. Open Windows 2008 x86 iso and replace the install.wim with the one from the x64 version. This is located in the sources directory of the iso. 5. Save the iso 6. Burn to cd or mount the iso from bartpe. 7. Run setup /noreboot from the root of the iso. You can add an unattend file as well 8. After it finishes phase one. Setup quits but does not restart the computer. 9. Then assuming your windows installation is on C: do this (get bcdedit from 32 bit version of win2k8) copy BCD (from x64 version) c:\boot\BCD bcdedit /set {bootmgr} device "partition=C:" bcdedit /set {default} device "partition=C:" bcdedit /set {default} osdevice "partition=C:" 10. reboot, windows installation will continue and you should not get a bcd error black screen. The initial problem stems from the BCD not getting created when installing 64 bit windows 2008 using the 32 bit installer. Enjoy! One more thing, if you use an unattended file phase 1 needs to be spicified for x86 architecture and phase 2, after first reboot needs to be specified for amd64 architecture... wierd but works! -Zex BCD64.rar
