Mostly, it happens after a fresh install of VirtualBox, and suddenly, the VM refuses to start. The root cause? Hardware virtualization support isn\u2019t enabled in your BIOS or UEFI settings. Sometimes, Windows might have Hyper-V turned on, which can also block VirtualBox from using virtualization features properly. These errors happen across different setups, whether you&rsquo;re running Intel or AMD CPUs, and fixing them involves a couple of steps\u2014either toggling settings in BIOS or turning off Hyper-V in Windows. Fixing these errors means enabling virtualization in your BIOS, or if that doesn\u2019t work, disabling Hyper-V in Windows. Both methods are straightforward once you know where to look. After applying these fixes, you should be able to create and run virtual machines without hassle. Now, let\u2019s get into how to do it step-by-step.<\/p>\n<h2>How to FIX: &lsquo;VT-x is disabled in the BIOS for all CPU modes&rsquo; in Windows 10\/11<\/h2>\n<h3>Method 1. Enable Virtualization in BIOS<\/h3>\n<p> This method makes sense if your system&rsquo;s BIOS isn\u2019t set to support hardware virtualization. The errors come up because virtualization extensions like VT-x (Intel) or AMD-V (AMD) aren\u2019t enabled. Enabling this support usually is enough to fix the problem\u2014on most machines, it just takes a few minutes. When you disable it, the hypervisor like VirtualBox can\u2019t access virtualization extensions, so that\u2019s when errors pop up. Enabling it helps Hyper-V, VirtualBox, VMware, and other hypervisors work smoothly.<!-- Entering BIOS setup varies, but here\u2019s a common process --> <\/p>\n<p><strong>Step-1: Enter in BIOS\/UEFI Setup<\/strong><\/p>\n<p>Here\u2019s how to get into BIOS or UEFI. The trick is, it\u2019s different depending on your machine. On Windows 10\/11:<\/p>\n<ul>\n<li>\n<div align=\"left\"><strong>A. Enter in BIOS from Windows 10\/11<\/strong> <\/p>\n<ul>\n<li>Press and hold <kbd>Shift<\/kbd>, then click <strong>Start<\/strong> &gt; <strong>Power<\/strong> &gt; <strong>Restart<\/strong><\/li>\n<li>After the restart, pick <strong>Troubleshoot<\/strong> &gt; <strong>Advanced options<\/strong> &gt; <strong>UEFI Firmware Settings<\/strong><\/li>\n<\/ul>\n<\/li>\n<li>\n<div align=\"left\"><strong>B. Enter in BIOS using a key (like F2, F12, DEL)<\/strong> <\/p>\n<ul>\n<li>Shutdown your PC, then power it on and repeatedly press the key that enters BIOS. Usually, F2, F12, F10, DEL\u2014depends on your manufacturer.<\/li>\n<li>Pro tip: if you\u2019re unsure, check your manufacturer\u2019s support page for exact keys.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>If your computer prompts you to press a key, do so quickly before it boots into Windows. Sometimes it\u2019s a bit tricky, but keep trying. Once inside BIOS\/UEFI, <\/p>\n<p><strong>Step-2: Enable Virtualization in BIOS\/UEFI<\/strong><\/p>\n<ul>\n<li>\n<div align=\"left\"><strong>AMD CPUs:<\/strong> Go to <strong>M. I.T<\/strong> or <strong>Advanced Frequency Settings<\/strong>, then look for <strong>SVM Mode<\/strong> (sometimes called \u00ab\u00a0Secure Virtual Machine\u00a0\u00bb) and set it to <strong>Enable<\/strong>. This allows your AMD processor to run virtualizations.<\/li>\n<li>\n<div align=\"left\"><strong>Intel CPUs:<\/strong> Navigate to the <strong>Advanced<\/strong> tab (or sometimes called <strong>CPU Configuration<\/strong>) and set <strong>Intel\u00ae Virtualization Technology (VT-x)<\/strong> &amp; <strong>VT-d<\/strong> to <strong>Enabled<\/strong>. If you don\u2019t see it, look for a similar setting under features like <strong>Security<\/strong> or <strong>System Configuration<\/strong>.<\/li>\n<\/ul>\n<p> <!-- Save changes after enabling virtualization --> <\/p>\n<p><strong>Remember to save and exit BIOS. Usually, it\u2019s <strong>F10<\/strong> or selecting <strong>Save and Exit<\/strong>. Once you\u2019re back in Windows, try running your VM again. If it still fails, move to the next method.<\/strong><\/p>\n<p><strong> <\/p>\n<h3>Method 2. Disable Hyper-V in Windows Features<\/h3>\n<p> This one trips up a lot of folks, especially since Windows\u2019 Hyper-V is turned on by default in some editions. Hyper-V acts like a built-in hypervisor, but VirtualBox can\u2019t natively run alongside it unless Hyper-V is turned off. Disabling Hyper-V is pretty easy, just a couple of clicks. The reason it helps is because Hyper-V reserves virtualization extensions for its own use, so VirtualBox or VMware can\u2019t access VT-x\/AMD-V anymore.<!-- How to disable Hyper-V --> <\/p>\n<p><strong>Step-1: Open Windows Features<\/strong><\/p>\n<ul>\n<li>Press <kbd>Windows<\/kbd> + <kbd>R<\/kbd> to open the Run dialog box.<\/li>\n<li>Type <code>optionalfeatures<\/code> and hit <b>Enter<\/b>.<\/li>\n<\/ul>\n<p><strong>Step-2: Turn off Hyper-V<\/strong><\/p>\n<ul>\n<li>In the Windows Features window, find <strong>Hyper-V<\/strong>.<\/li>\n<li>Uncheck the box next to it, then click <strong>OK<\/strong>.<\/li>\n<\/ul>\n<p>Be aware: on some setups, Hyper-V might be grayed out or not visible. If so, you can disable Hyper-V through PowerShell or Command Prompt:<\/p>\n<pre><code>Disabling Hyper-V via PowerShell: DISM \/Online \/Disable-Feature:Microsoft-Hyper-V-All <\/code><\/pre>\n<p>Or using Command Prompt as administrator:<\/p>\n<pre><code>sc config vmms start= disabled sc stop vmms <\/code><\/pre>\n<p>After turning Hyper-V off, restart your PC. Now, try creating your VM again. That usually does the trick \u2014 on some setups, Hyper-V\u2019s let-hypervisors run interference.<\/p>\n<h2>Wrap-up<\/h2>\n<p> Getting virtualization enabled or disabling Hyper-V tends to fix these pesky errors. In my experience, the BIOS setting tweak is the most reliable, but sometimes Windows just keeps Hyper-V active, so the second method is helpful. It\u2019s kinda weird how Windows can block VirtualBox without you realizing, especially after a Windows update or clean install. But both fixes are straightforward once you know where to look. Hopefully this shaves off a few hours of head-scratching for someone. If the errors persist after trying these, it might be worth checking if your CPU actually supports hardware virtualization or if some other security setting is blocking it. Good luck! <\/p>\n<h2>Summary<\/h2>\n<ul>\n<li>Enable virtualization in BIOS\/UEFI settings.<\/li>\n<li>Disable Hyper-V in Windows features.<\/li>\n<li>Restart after making changes and retry creating your VM.<\/li>\n<\/ul>\n<h2>Final thoughts<\/h2>\n<p> Sometimes, fixing virtualization issues is just about checking the BIOS or turning off Hyper-V. Not everything is straightforward, but once you get it enabled or disabled, VirtualBox (or other hypervisors) should run fine. Fingers crossed this helps someone avoid hours of frustration.
