I've used Ubuntu and Mint distros before.
My Lenovo was selected because it was on the Qubes lists. It was supposed to be a barebones refurbished.
Not great specs, but I think it was minimum recommended.
Do you think I could dual-boot Qubes?
I have done much dual-booting since UEFI, and I am enjoy my free windows 10
(As much as anyone CAN enjoy windows.)
