Hitman contracts on pc

Hello,
a friend lend my games hitman contracts
and during the installation it makes me "Insert Disk 2 " and also just below it is "name of the road" and a field of writing and I do not know what to put in I try lots of stuff but I do not know if it's a code or a link on my computer
Please help me

Insert the CD No. 2 in place of No. 1 CD and click on ok

I get the same error with Hitman: Contracts.
Disabled all AV software.

When trying to run with a copied CD (used BW5), I get a "Please insert original disc instead of backup" error
