Say steam it should be installed over the folder where your backup is stored (if you want you can put it back on C: before) ... after this start steam and it will automatically download and check all files that are missing maybe. All your games are still available than.
I have a counter strike source copy since 8 years in my steam folder and I reinstalled my OS again nearly every 2 years...
Just to confirm, I already have my previously and working steam game in my drive. If I re-install Steam and it prompts me to 'Install' the game again and I click 'Install', it won't erase my existing copy? Thanks.
