Well after talking to some MS developers on the windows team, it turns out vista build 5270 does NOT have EFI enabled on it... to quote one of them "That is a known bug. EFI is not enabled yet. It doesn't look like it will be fixed for Beta 2" so this is why we can not boot it on a mac yet, it's not because mac wont support it, it is just because Microsoft hasn't enabled it yet!

They also say internally they have it running on a Intel Mac already with the build that does support EFI! so looks like by the time RTM comes around we will be able to boot it on a mac when EFI is enabled on the vista boot cd and in vista... they said it doesnt even work on the DVD yet, so the people that where "booting" too the cd were not booting through EFI, but the stub they put in place for EFI which does nothing so far besides show a "press a key to boot from cd" message

Gee, EFI support sounds like one of those core OS features that definitely needs to be integrated by a beta 2 release. Does that make B2 non feature complete, even if it is a feature like Sideshow that can't be used on any *regular* PC yet?

well EFI can't be used on regular PC's yet either.. .only intel 975x boards and mac's support it and 975x's are disabled by default too.. so not having it yet is no big deal

This is interesting, no wonder. Its one of the reasons why I have put off my purchase on an iMac Core Duo, the other is the Core Duo does not have any 64-bit Extensions. But here's the question thats bothering me, Windows XP Professional x64 supports EFI, it should at least be bootable then display a warning message about the processor not being 64 bit enabled.

well its IA64 xp (itanium) not the amd64 xp that supports efi and the 64bit warning shows up before the press any key to boot to cd. its somehow part of that loader. (if i remeber correctly)

The 64bit loader wont even load on a 32-bit system, so that won't work trying

Who would buy a macbook and want to install a Windows OS? I'm a Windows user through and through, but if I bought a mac, there's only one OS I'd be running on it and it sure as hell isn't Windows.

personally I'd want what ever OS I want on my system, I never liked the idea of being tied to OSX on a mac (sure you could use linux, but 2 os is still a limit) since there are more OS's for intel being able to boot other os's is a good thing, and the fact MS has Mac's up and running windows Vista says this is possible, and thus gives us choice in the end of what we run on Apple's over priced computers.. but the real idea behind this post is the fact people are screaming mac's wont boot EFI well they are trying to boot on something that doesn't even have a working boot loader on it to start with for EFI so just trying to clear things up here

Wow, and there are people who have quit work to find out that what they were working on sooooo hard didn't work because EFI just wasn't on Vista yet. Ouch.

Slight exaggeration on quitting work, but I'm sure you see my point.

"Who would buy a macbook and want to install a Windows OS? I'm a Windows user through and through, but if I bought a mac, there's only one OS I'd be running on it and it sure as hell isn't Windows."

Uh, you do realize that you can run more than one operating system on a computer don't you? Just because you have Windows installed doesn't mean OS X is out. Being able to run Mac OS and Windows on the same computer without emulation for the first time ever seems like a pretty big even to me. You really don't see the attraction of being able to run OS X whenever you want but still boot into Windows to play games or run Windows software? I doubt anyone was talking about buying a Mac and running only Windows on it.

"What is EFI?

Extensible Firmware Interface. It's what Intel is replacing the ancient BIOS with (the one from 1981 that we all still use for some reason).

Just need to get Mac OSX running on any windows machine, then problem is solved. Buy a cheap dell laptop and load up os x on it.

Who really wants to spend all that money just because the laptop says apple on it?

problem is you cant do that yet... they dont support EFI yet, wait a year and then they wil only very few Intel boards support EFI at all

The Febuary CTP of Vista is supposed to be feature complete. It's supposed to have EFI enabled.

And to TRC:

The first post that you quoted went on to say that he could run OS X and Linux, but he wants even more choices and doesn't want to be locked to just those two. If you would read past the first sentence, you would see where he expands upon the initial, summarizing sentence (which is how you're supposed to write). So, chill out.

I have a copy of Mac OSX running on my old dell....

that'd be the developer edition which was hacked to start with and doesnt even have EFI on it

did you read my original post by MS? they said it would NOT be in Beta 2 complete... just because an OS is feature complete doesn't mean it's a complete OS... i know makes no sense but feature complete is only completition of code for features they list as mandatory... EFI isn't mandatory yet They said sometime after beta 2 EFI would be turned on and also support for recognizing Blu-Ray discs (recog. not play!) would be added later! so the feb CTP will NOT have EFI like they said and beta 2 also will not have it enabled..

Really? I know plenty of people that would be interested in doing just that.

I think the point for many isn't to run just Windows on them (although I can see people do it for the design), but to run both.

Think of a scenario with for example Windows as a game platform, with OS X for the rest. Full speed, no emulation layers, same box!

This route would also likely be a legal one too, as opposed to the hacked developer builds.

OS X + Vista on a slick Intel Core system sounds pretty appealing to me at least, maybe even moreso than Windows + Linux in the same scenario. :)

Amen to that! I can't wait...but I guess I'll have to, at least until Vista RTMs (and until I can afford a new laptop).

I like how their laptops are small and their design is better then most of the intel based ones out there right now...thats the only reason i'd get a mac right now... but i'd want to use windows and mac os x personally...

    • This sounds like underneath the nice marketing spin, either someone at Adobe got tired of their lazy devs and asked Microsoft to train them to help sort Adobe's old spaghetti code to make it go faster, or Microsoft wanted Adobe's crap to run better on Windows to make it look better against Apple, so they offered to intervene. Either way, GOOD.
    • My favorite file manager for Windows 11 finally gets a long-requested feature by Taras Buria Files is among the best File Explorer alternatives for Windows 10 and 11. This free app is packed with all sorts of features and conveniences, but there is one crucial feature that is still missing—Tree View. Fortunately, the latest update in the Preview channel finally delivers it. With version 4.1.4, which is now available for download in the Preview channel, developers implemented Tree View, a new mode that displays folders in an expandable hierarchy. Windows 11's stock File Explorer always had this feature, but it was nowhere to be found in Files until now. Starting with the latest preview update, you can expand each drive and its nested folders without leaving the current location and then open the folder you need in the main view. To try Tree View in Files, update the app to the latest preview version, then click the small arrow next to a drive to expand its content. The developers say they are rolling out Tree View in Preview first to gather feedback from users and improve the feature before bringing it to all in the stable channel. In addition to Tree View, Files 4.1.14 improves the Windows Fonts folder. You can now preview each font directly in Files with no need to open the built-in font viewer. For now, these two features are only available in the Preview channel. For those using the stable release, developers recently released version 4.1.3, with improvements for the built-in tag system, on-demand folder size calculation, and plenty of various fixes. You can check out the full release notes here. You can download Files from the Microsoft Store (paid version) or its official website (free).
    • Who is paying for this 30x scale-up? Its sounds expensive.
    • Millions of users to benefit from Windows 11's new performance boost on Adobe Photoshop by Sayan Sen Despite the advent of AI-generated imagery, Adobe's Photoshop remains one of the most popular tools on this planet. Adobe does not have a publicly reported total user count but it's probably not wrong to assume there are millions. As of 2025, Adobe Creative Cloud has had approximately 41 million paid subscribers, many of whom likely use Photoshop. In addition, more than 166,000 companies worldwide are apparently also using the app. These figures are according to a very recent report by SQ Magazine. Out of them, it is fair to assume that many are probably running Windows. As such, there is good news for these users as Microsoft has announced Photoshop is getting a big 20% performance boost on x86-64 (AMD64) systems and a 13% bump-up on Arm devices. This is definitely great news for them as many have complained about the slow performance and general sluggishness of Photoshop on Windows 11 ever since the advent of the latter back in 2021. If you are wondering how Microsoft managed to do this, the answer lies in a combination of compiler-level optimizations and a technology called Sample Profile Guided Optimization (SPGO). According to Microsoft, Adobe worked closely with the company’s Visual C++ team and adopted the latest MSVC toolchain enhancements together with SPGO to squeeze more performance out of Photoshop’s CPU-bound workloads. Unlike traditional Profile Guided Optimization (PGO), which requires developers to create special instrumented builds and run lengthy training workloads, SPGO gathers performance data directly from optimized release binaries. This means Adobe could collect real-world usage information which gives a major advantage to this technique, as companies could leverage data collected from actual customer workloads rather than only relying on synthetic benchmark runs. In theory, this should allow optimizations to better reflect how users interact with software in the real world. Thanks to this, there are improvements to code layout, function inlining, hot-and-cold code separation, and other low-level tweaks that help processors execute instructions more efficiently. Essentially the compiler is better able to identify “hot” code paths, those which are most frequently executed, and optimize them accordingly.
