I searched through the last 4 months worth of postings to attempt to follow the prompt:

• Carnosaur is some cheap Roger Corman fun schlock
• Deathwish 3, Canon action film that is entirely over the top. Watch a 64 year old Charles Bronson do slow-mo vigilantism.
• Death Race 2000, David Carradine in a Roger Corman flick where the race is also scored by killing bystanders.
• Ninja III: The domination, Canon tried to do series but failed horribly, this one's opening scene agrivated my Wife out of watching it.
• Petey Wheatstraw, I have converted a few people to bad movies through Rudy Ray Moore and this is a soft entry.
• Return of the Living Dead, Oh baby, this takes zombies in a decidedly non-Romero direction and is full of fun.
• The Lair of the White Worm, I've seen this a few times over the last few years and I find myself chuckling throughout.

Why not install a live disc type image to USB and try out different varieties? Linux Mint offers three live images with Cinnamon, MATE, and XFCE.

I quickly found this article on installing them to USB: https://itsfoss.com/linux-mint-live-usb/

Many popular distributions offer live images so you can try before installation.

There needs to be some mechanism to recover your machine should this happen. It's not that much more difficult to do it on a windows machine either.

The truth of the matter is is if somebody has physical access to your machine it's not your machine anymore. They can pull out the hard drive and plug it into a machine that they have a password for and read from it if it's not encrypted. So on and so forth.
