Select your PrimeOS ISO. I used the standard version of the ISO on my HP T520. If you have older hardware, then use the Classic ISO.
Ensure you have selected the correct USB drive. Leave the partition scheme as MBR and the rest of the options as default.

In here, ensure that legacy support is enabled and Secure boot is disabled
Press F10 to save and then go back and select the option to save changes and Exit

Scroll down and select PrimeOS Auto Install to a specified hard disk

Ensure you select your internal harddrive (normally sda). This will then do a complete format of your harddrive and then install PrimeOS for you.
Once done, you will see this option
Select the reboot option and remove the USB stick from your device.
Once PrimeOS boots, you will see this
Enter in those details and you will see the PrimeOS home screen
