If you have trouble booting an ISO image, here are some troubleshooting steps:
- Verify the downloaded ISO image using hashes or GPG key.
- Verify that your machine is x86-64 architecture (standard Intel or AMD 64-bit).
- If you’re trying to run a 64-bit virtual machine, verify that your 64-bit processor supports virtualization and that virtualization is enabled in the BIOS.
- If you’re trying to create a bootable USB from an ISO image, try using Balena Etcher which can be downloaded at https://www.balena.io/etcher/.
- Certain display adapters may require the
nomodesetoption passed to the kernel (see https://unix.stackexchange.com/questions/353896/linux-install-goes-to-blank-screen).
- If you’re still having problems with our 64-bit ISO image, try downloading the standard CentOS 7 64-bit ISO image or Ubuntu 18.04 64-bit ISO image and seeing if they run. If they don’t, then you should double-check your 64-bit compatibility.
- If all else fails but standard CentOS 7 64-bit or Ubuntu 18.04 64-bit installs normally, then you can always install our components on top of them as described on the Installation page.
