I have an ASUS laptop with an SSD (where my Windows OS is installed) and a completely empty 1 TB HDD. Can I just boot the laptop from a USB on which the Qubes .iso is located, and then install Qubes on the HDD? Will this allow me to then choose between Qubes & Windows upon switching the computer on?
Thanks in advance.
It is very possible however this is not recommended for security reasons, but if you think you need to do this go to https://www.qubes-os.org/doc/multiboot/ and execute the steps there.
