Microsoft revealed today that it will not support EFI booting for Windows Vista on its launch. The news will be a shock for owners of Intel Macs who had hoped they would be able to dual-boot between Windows Vista and OS X. Intel Macs only support booting via EFI.
Speaking at Intel Developer Forum San Francisco, Microsoft development manager, Andrew Ritz, also revealed that there will never be any support for booting Windows via EFI on systems with 32-bit processors.
Although Microsoft has previously said EFI booting would be supported by Vista, Ritz admitted that EFI support won't be seen in any version of Windows until the release of Longhorn Server.
