Dualboot won't boot. Tried boot repair

The only OS I see mentioned in your paste is

Linux Mint 21.2, victoria, x86_64

If you refer to the Support and Help rules you’ll note

Linux Mint is an OS based on Ubuntu, and supported by the Linux Mint team.

FYI: I’d start by checking the health of your sdb disk/device, then check for partition/logical problems if it’s actually healthy. I only scanned briefly though, as details in your paste show nothing I saw as on-topic here
