## Minimum
* 64-bit Intel or AMD processor (x86\_64 aka x64 aka AMD64)
* [Intel VT-x] with [EPT] or [AMD-V] with [RVI]
* [Intel VT-d] or [AMD-Vi (aka AMD IOMMU)]
* 4 GB RAM
* 32 GiB disk space
- **CPU:** 64-bit Intel or AMD processor (also known as `x86_64`, `x64`, and `AMD64`)

## Recommended
* Fast SSD (strongly recommended)
* Intel IGP (strongly preferred)
* Nvidia GPUs may require significant [troubleshooting][nvidia].
* AMD GPUs have not been formally tested, but Radeons (RX580 and earlier) generally work well
* See the [Hardware Compatibility List]
* TPM with proper BIOS support (required for [Anti Evil Maid])
* A non-USB keyboard or multiple USB controllers
* Also consider the [hardware certification requirements for Qubes 4.x].

- **Other:** Satisfaction of all [hardware certification requirements for Qubes 4.x]
## Choosing Hardware
* Please see the [Hardware Compatibility List] for a compilation of hardware reports generated and submitted by users across various Qubes versions.

## Important Notes
* **Installing Qubes in a virtual machine is not recommended, as it uses its own bare-metal hypervisor (Xen).**
* Qubes **can** be installed on systems which do not meet the recommended requirements.
- **Installing Qubes in a virtual machine is not recommended, as it uses its own bare-metal hypervisor (Xen).**
- Qubes **can** be installed on systems which do not meet the recommended requirements.
Such systems will still offer significant security improvements over traditional operating systems, since things like GUI isolation and kernel protection do not require special hardware.
* Qubes **can** be installed on a USB flash drive or external disk, and testing has shown that this works very well. A fast USB 3.0 flash drive is recommended for this.

(As a reminder, its capacity must be at least 32 GiB.)
Simply plug the flash drive into the computer before booting into the Qubes installer from a separate installation medium, choose the flash drive as the target installation disk, and proceed with the installation normally.
After Qubes has been installed on the flash drive, it can then be plugged into other computers in order to boot into Qubes.
