Depending on the computer, this low-level software is may be called the “BIOS” or “UEFI”.
When a computer boots up, it first runs low-level software before the main operating system. “Booting” is the process of starting your computer. This section will demonstrate a simple installation using mostly default settings. Instead, choose the "Install Qubes OS" option. Note: Using Rufus to create the installation medium means that you won't be able to choose the "Test this media and install Qubes OS" option mentioned in the example below. If those settings are not nested under the Advanced tab, you might find them under the Security tab. This external guide made for Intel-based boards can help you figure out how to enter your BIOS or UEFI to locate and activate those settings. This parameter should be activated in your computer’s BIOS or UEFI, alongside the standard Virtualization ( Intel VT-x) and AMD Virtualization ( AMD-V) extensions. For Intel-based boards, this setting is called Intel Virtualization for Directed I/O ( Intel VT-d) and for AMD-based boards, it is called AMD I/O Virtualization Technology (or simply AMD-Vi). Without it, Qubes OS won’t be able to enforce isolation. You may also find it helpful to consult the Hardware Compatibility List.Įven on supported hardware, you must ensure that IOMMU-based virtualization is activated in the BIOS or UEFI. Other hardware may require you to perform significant troubleshooting.
To ensure compatibility, we strongly recommend using Qubes-certified hardware. Qubes OS has very specific system requirements. See installation security for more information. Do not install Qubes on a computer you don't trust. No software can provide security if it is installed on compromised hardware. Warning: Qubes has no control over what happens on your computer before you install it.
