Microsoft said today the initial version of Windows Vista won't feature support for EFI booting. This means it will be impossible to run Windows Vista on the new Intel-based x86 computers from Apple.
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.
It will not be available in the release version of Windows Vista later this year – Microsoft says people will have to wait for an unspecified 'subsequent release of Windows client'. Ritz could not say whether that would be a service pack update to Vista or the next-generation of Windows.
