Microsoft bombshell: no EFI support for Vista

Friday 10, March 2006 | By Dan Warne

From: Epinions › Hardware

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.

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.

NO EFI FOR YOU! Microsoft Development Manager Andrew Ritz has bad news for PC users hoping for next-gen booting.

Extensible Firmware Interface (EFI) is the modern and flexible successor to the 20-year-old PC BIOS. It is responsible for initialising hardware in the PC, and importantly, device drivers are stored in the EFI flash memory rather than being loaded by the operating system. It is a major change for the PC industry and both PC makers and Microsoft have been slow to make the switch. Because the Apple Intel Mac platform is entirely new, it does not have any legacy support concerns. It was hoped that 2006 would be the year PC makers would make the switch. Microsoft's lack of Windows support is a huge blow to Intel's hopes, and removes most of the incentive for PC makers to implement it in the short term.

That's terrible news for Intel Mac users who have been hoping that they could dual-boot Windows and Mac OS X on their new Macs: not only are their processors not 64-bit (and thus will never be supported by Windows EFI booting) but Windows Vista won't boot on EFI anyway.

It said its decision to 'reprioritise' EFI development to the server version of Windows was based on a lack of available desktop PCs with EFI support on the market.

"A combination of factors changed our plans. The big one, in my opinion was platform availability. With this huge move to 64-bit based platforms and for us to support it, we needed to see a large heterogeneous sample of 64 bit implementations out there for us to feel comfortable in supporting it." said Ritz.

I think this is a big mistake on Microsoft's part. I cannot imagine that it would take that much to add support for EFI (albeit I'm not a developer, so I could be wrong). We need to get rid of the aging BIOS and move to EFI and Microsoft not adding support for it means that OEMs won't add it (obviously). Bad, very bad decision.

Well theres a lack of desktop PC's with EFI support on the market because there is a lack of operationg systems supporting EFI. This is friggin stupid. Vista support all kinds of silly features that arnt released yet, where are thoes super high reselution displays they were touting a while back which vista will support?

They have a point, do any of you have a PC with EFI? I doubt it. It's useless right now. BUT...

I think new motherboards should start having them though, but I haven't heard of any PC motherboard company making the switch at all. And if Windows Vista EFI Support was only for 64-bit then its useless to Mac users since they're on 32-bit processors. For the ones that want EFI support, lets hope for a SP that adds it ;)

I find the current BIOS not user friendly at all for newbs, I've helped people over the phone with BIOS issues and its not easy since all BIOS are different. Hopefully EFI makes one standard and sets it easy.

Call me crazy, but I think this is all politics.

I think this has something to do with the Intel Macs and the fact that many people were going to purchase them only because they could run both OS X and Windows.

Does anybody else feel like this is just a stab at Apple from MS? It seems so... Before, MS had every intention to do it, then the craze set in that people would be able to run Vista on their shiny new Intel Macs, and now MS isn't going to support it...

Strange, very strange.

Ahh yes, Micro$haft's brilliant R & D always leading the industry with innovation................NOT!!!

One would think that a company that has 80% of the World using it's product would prefer to be in the driver seat in the industry.....but not so it's seems...instead a small company with an Apple as it's logo still leads in design with 8% of the Market share making windows users dream of the next best thing. lol They are certainly not afraid to take the bull by the horns.

I completely agree with you. I think this is a stab right at Apple since Apple said that they don't have a problem with users installing Vista on the new Intel-based Macs. Very poor decision on Microsoft's part.

EFI can load any program, including a traditional BIOS.

If Apple junkies want to run XP on their new Macs, they can write a no-frills BIOS. XP only needs a few Interrupts to set up and boot.

Well it can't be that easy. If it was, then wouldn't someone already have figured out how to do it. Especially with $12,000+ on the line :p

They have a point, do any of you have a PC with EFI? I doubt it. It's useless right now. BUT...

I think new motherboards should start having them though...

Certain Intel mobo's have EFI, and a few Media Center PC's use EFI, but they include a CSM so Windows behaves as normal.

I completely agree with you. I think this is a stab right at Apple since Apple said that they don't have a problem with users installing Vista on the new Intel-based Macs. Very poor decision on Microsoft's part.

If anything, MS wants Windows on Mac's, that then increases their market share to PC and Mac users, making them more money.

and bob, elilo

    • @Sayan...I have defended you at various points as I hope you know. This headline however is utter trash...shame on you sir!
    • An actual cosmic "Eye of Sauron" had been looking straight at us all along by Sayan Sen Image by Kovin P. Vasquez via Pexels | Not representative An international team of researchers has solved a long-standing mystery surrounding a distant blazar known as PKS 1424+240, helping explain why it produces some of the brightest high-energy gamma rays and cosmic neutrinos ever observed despite appearing to have a relatively slow-moving jet. The findings were published on June 6 in Astronomy & Astrophysics Letters. The study addresses a broader challenge in astrophysics: understanding how extreme cosmic objects accelerate particles to very high energies and produce very high-energy (VHE) photons and neutrinos. PKS 1424+240 is located billions of light-years from Earth. It has attracted attention for years because it is both a powerful source of VHE gamma rays and the brightest known neutrino-emitting blazar in the sky, according to observations by the IceCube Neutrino Observatory. It is also associated with one of the strongest peaks in IceCube's nine-year neutrino sky map A blazar is a type of active galactic nucleus powered by a supermassive black hole that pulls in surrounding matter and launches jets of plasma moving close to the speed of light. What makes blazars unique is their orientation. One of their jets points almost directly toward Earth, making them appear exceptionally bright across the electromagnetic spectrum and allowing scientists to study some of the most extreme physical processes in the Universe. The scientists exclaimed it's like the 'Eye of Sauron' in deep space. Usually, the brightest gamma-ray-emitting blazars are expected to have jets that appear to move very quickly. However, radio observations of PKS 1424+240 suggested that its jet was moving much more slowly, creating a contradiction that became part of a long-running problem known as the "Doppler factor crisis." To investigate, researchers analyzed 15 years of observations from the Very Long Baseline Array (VLBA), a network of 10 radio antennas spread across the continental United States, Hawaii and St. Croix. Using a technique called Very Long Baseline Interferometry (VLBI), astronomers combine signals from widely separated radio telescopes to create a virtual Earth-sized telescope capable of revealing extremely fine details. The team combined 42 polarization-sensitive radio images collected between 2009 and 2025, creating a much deeper and more detailed view of the jet than had previously been possible. The observations were carried out as part of MOJAVE (Monitoring Of Jets in Active galactic nuclei with VLBA Experiments), a long-running program that studies the brightness, polarization and magnetic field structures of jets produced by active galaxies. The project aims to better understand how activity near supermassive black holes is linked to high-energy radiation and neutrino emission. “When we reconstructed the image, it looked absolutely stunning,” said Yuri Kovalev, lead author of the study and Principal Investigator of the European Research Council-funded MuSES project at the Max Planck Institute for Radio Astronomy. “We have never seen anything quite like it — a near-perfect toroidal magnetic field with a jet, pointing straight at us.” The image revealed an unusual geometry. The researchers found that Earth lies almost directly in line with the jet, with a viewing angle of less than 0.6 degrees. In simple terms, astronomers are looking almost straight down the jet. This turned out to be the key to the mystery. Because the jet is aimed almost directly at Earth, a relativistic effect called Doppler boosting dramatically increases its apparent brightness. The study found that this effect boosts the emission by a factor of about 30 while also making the jet appear slower than it actually is. “This alignment causes a boost in brightness by a factor of 30 or more,” said Jack Livingston, a co-author at the Max Planck Institute for Radio Astronomy. “At the same time, the jet appears to move slowly due to projection effects — a classic optical illusion.” The nearly head-on view also gave scientists a rare look at the jet's magnetic field. Using polarized radio signals, they detected a clear toroidal, or doughnut-shaped, magnetic field component. The observations suggest the jet carries an electric current and that its magnetic field helps launch, shape and stabilize the flow of plasma. Researchers believe this magnetic structure may also play a key role in accelerating particles to energies high enough to produce both gamma rays and neutrinos. “Solving this puzzle confirms that active galactic nuclei with supermassive black holes are not only powerful accelerators of electrons, but also of protons — the origin of the observed high-energy neutrinos,” Kovalev said. The research was conducted under the MuSES (Multi-messenger Studies of Energetic Sources) project, which investigates how active galactic nuclei accelerate particles and generate different cosmic signals, including light and neutrinos. Scientists say understanding how protons are accelerated and linked to neutrino production remains one of the major unanswered questions in astrophysics. The findings help explain why some blazars can appear to have slow jets while still producing extremely bright high-energy emissions. More broadly, the study strengthens the link between relativistic jets, magnetic fields, gamma rays and high-energy neutrinos. Researchers say the results provide new clues about how some of the Universe's most powerful natural particle accelerators work and offer important insights for multimessenger astronomy, which combines different types of cosmic signals to study extreme events in space.

    • Microsoft Weekly: Surface Laptop Ultra, Windows 11 context menus, Build 2026 recap, and more by Taras Buria This week's news recap is here, with Microsoft announcing the new Surface Laptop Ultra, fresh chips from NVIDIA for Windows on ARM, a no-build week, fixes for Windows 11's context menus, gaming news, reviews, and more. Quick links: Windows 10 and 11 Windows Insider Program Updates are available Reviews are in Gaming news Great deals to check Windows 11 and Windows 10 Here, we talk about everything happening around Microsoft's latest operating system in the Stable channel and preview builds: new features, removed features, controversies, bugs, interesting findings, and more. And, of course, you may find a word or two about older versions. At Computex 2026, together with NVIDIA, Microsoft announced the Surface Laptop Ultra, its most powerful laptop to date, powered by NVIDIA's RTX Spark processor. Details about this computer are currently scarce, as Microsoft has only revealed certain parts of its specs. So far, we know that the computer has a 15-inch mini-LED display, a rich set of ports, a powerful processor, and all-day battery life. It also comes with a new wallpaper, which you can already download here in full resolution. The Surface Laptop Studio is not the only NVIDIA-powered Surface, which Microsoft unveiled this week. At Build 2026, the company also debuted the Surface RTX Spark Dev Box, an odd-shaped desktop with a 20-core NVIDIA Grace CPU and an NVIDIA Blackwell RTX GPU with 6,144 CUDA cores and fifth-generation Tensor Cores with FP4 precision, connected via the NVIDIA NVLink-C2C chip-to-chip interconnect for high performance. According to Microsoft, it can run models with up to 120 billion parameters locally without relying on cloud GPU infrastructure. These two new Surface devices are likely to cost quite a lot, and for those who need a more affordable device, Microsoft is preparing the next-gen Qualcomm-powered Surface Pro and Surface Laptop. This week, details about these two devices leaked in plenty of detail. Other announcements at Build 2026 include the following: Microsoft unveils new security tools for IT admins and developers building AI products Microsoft announces Scout, an OpenClaw-powered personal agent for enterprise customers Microsoft unveils MAI-Thinking-1 reasoning and MAI-Code-1 coding models Microsoft announced a new Windows 11 native command-line utility Microsoft unveils Majorana 2 quantum chip, accelerating commercial timeline to 2029 Microsoft believes that AI agents will eventually replace apps through Project Solara Microsoft introduces Web IQ, a Bing-powered search system built for AI agents Last week, Microsoft released a new Experimental build, which introduced a major Start menu upgrade. It now lets you toggle off specific parts of the menu without affecting other features, resize the menu, and hide additional UI elements. We published a closer look here, so if you want to know what Microsoft is cooking without enrolling in the Insider program and installing unstable builds, check it out. Speaking of new features, many users are very annoyed about the way Microsoft delivers them. Recently, a frustrated user shared their experience with gradual rollouts, and even Microsoft engineers admitted there is a flaw in the system that prevents new features from applying properly. One of those new features includes the ability to uninstall AI models in Windows 11 with a single click. Windows 11 is finally getting fixes for its slow context menus. Marcus Ash from Microsoft confirmed that the company is working on fixing Windows 11's context menus. Reworked context menus are going to be faster, simpler by default, and "configurable to what you use most." According to Marcus, Microsoft will share more details soon. Windows Insider Program Windows 11 preview builds, released last week, are now available for download as standalone ISO files. These days, Microsoft regularly pushes new images, allowing users to clean-install its recent Windows 11 preview builds faster and easier. If you want to try the latest Windows 11 features without jumping through the Windows Update hoops, get those new images here. Sadly, Microsoft did not release new Windows 11 preview builds this week. Come back next time. Updates are available This section covers software, firmware, and other notable updates (released and coming soon) delivering new features, security fixes, improvements, patches, and more from Microsoft and third parties. Microsoft is preparing new features for Teams. Later this month, the messenger will receive a new download manager with auto-dismissing notifications, reducing clutter and making the overall experience less annoying when dealing with downloads. Mozilla released Firefox 151.0.3, a new bug-fixing update for the browser. It is a small release, which fixes problems with pasting into text fields and the oversized VPN button on the toolbar. The update is now available for all users in the Release channel. Here are other updates and releases you may find interesting: VS Code 1.123 introduces massive upgrades for persistent AI developer workflows Microsoft OneDrive is getting a simple yet much-needed feature Microsoft faces heat after quietly blocking promised Office features on Apple systems Microsoft resumes forced Copilot app installation on some Windows PCs Browser vendors pen an open letter to Microsoft, saying "enough is enough" Here are the latest drivers and firmware updates released this week: AMD Radeon Software 26.6.1 with optimizations for F1 25: 2026 Season, World of Tanks: HEAT, and various bug fixes. Reviews are in Here is the hardware and software we reviewed this week Steven Parker dropped more mini PC reviews this week. GEEKOM Air12 2026 Edition is a low-power, affordable computer with an Intel Tiger Lake Pentium Gold processor, up to 16GB of memory, and 512GB of storage, costing just $349. It is light, quiet, energy efficient, and has modern ports on the front. However, the front-facing USB Type-C is data-only, and there are some quirks with the computer's memory, so check out the full review. The AMD RX 9070 GRE has been released worldwide, and we published a benchmark review comparing this powerful graphics card to the RX 9070 XT, 7800 XT, the NVIDIA RTX 5070, and RTX 4070. It has solid, balanced performance, plenty of RAM, and low temperatures, but watch out for mediocre ray tracing performance and not the best efficiency. Also, we reviewed the Cuktech 10 Ultra, a compact, high-power charger with four ports and a big display full of various stats. This tiny charger can pull nearly 120W and spread that power according to each connected device's needs. It also comes with a high-quality 240W cable, three power modes, and retractable prongs. The best part? It is quite affordable, just make sure you have an outlet placed in the right spot to benefit from the built-in display.
