Help with installing debian

[Rohan J. Tilwani]

Hello there,
I am facing a serious issues installing the "Bullseye" version of debian.
Especially with Disks. I would be glad if you help me out. I am trying to
install live+nonfree latest version of debian. Initially i get error that
says SM bus busy. After I boot into live environment, I get another issue.
I cant locate my secondary HDD on Lenovo slim 5.(i5 11th gen, Nvidia MX450,
8gigs RAM, 256gigs SSD+1TB HDD). Please help.
Thank you.
