These steps do not turn off UEFI (which isn’t possible, since that’s what your motherboard is running), but they do enable you to boot into Windows the traditional way (via the MBR). Two separate steps are often required to fully achieve this we have documented both with visual guides and sample images taken from the more-common UEFI configuration pages: Most PCs and laptops currently shipping with and using the UEFI firmware and bootloader can be configured to disable UEFI entirely and instead revert to “legacy” MBR boot mode. These limitations are not short comings of EasyBCD nor can they be lightly bypassed, they have been put in place by Microsoft. It abides by the restrictions Microsoft has placed on the bootloader that will block any attempts to load non-Microsoft-signed kernels (including chainloaders) from the top-level BCD menu, and it will create 100%-compliant UEFI entries other installed Windows operating systems on your PC. In UEFI mode, much of EasyBCD’s functionality will be disabled for the safety of your PC. You can add multiple Windows Vista, Windows 7, Windows 8, and Windows 10 entries and you can also boot into BCD-based portable media, such as WinPE 2.0+ images.ĮasyBCD is 100% UEFI-ready. You also cannot add DOS, Linux, BSD, or Mac entries. ![]() This means that you can no longer use EasyBCD to add Windows 9x, XP, or Server 2003 entries to the BCD bootloader menu. If your Windows PC is booting in EFI mode, Microsoft has blocked the loading of legacy or non-Windows operating systems from the BCD menu. Press ‘OK’ to continue or ‘Help’ to read more about these limitations and possible workarounds. Due to limitations set by Microsoft, many of EasyBCD’s multi-booting features cannot be used in EFI mode and have been disabled. Upon starting EasyBCD on a machine that is currently booting in UEFI mode, the following dialog will be seen:ĮasyBCD has detected that your machine is currently booting in EFI mode. It is not fundamentally incompatible with dual-booting, but the way that Microsoft and PC manufacturers have implemented UEFI, it makes it a lot harder to do so. ![]() Newer computers are shipping with a BIOS replacement called UEFI – short for Unified Extensible Firmware Interface – that completely changes the way operating systems interact with and are loaded from the hardware in your PC. The changes are not small and have had a massive effect on the process of dual-booting on a Windows machine. ![]() Unfortunately, W10 (and W8.With the release of Windows 8 and Windows 10, many new computers are shipping with something known as the UEFI firmware and boot manager in place of the traditional BIOS and MBR approach to starting up your PC. That turned out to be a problem with W10 authorization where it wasn't allowing the program access to various system files and folders without me going in and telling W10 to let it do what it needed to do. I did have a problem when I first switched to W10 from W7 with Hauppauge's WinTV8 application which worked perfectly on W7, and appeared to install fine on W10 but didn't do anything when started. I don't recall ever seeing that, though I suppose it might have happened once, years ago on first installation but if so it obviously never caused a problem.
