Create bootable file for imac
I am an intern at a company and I have been provided an Intel atom system which certainly is not gonna be able to run smoothly at this age of online everything, so I requested a change and they invited me to fix a imac that does not have a operating system as I had never used a mac but I still thought installing a mac from a bootable pendrive is easy but well apparently its not. I don't know where I can get an ISO file and how do I make a pendrive bootable.

What model/year? You might not even need to create a iso - many macs will let you install the OS off the internet

All Macs introduced since about 2012 can do "Internet Recovery" if you boot while holding down Command-Option-R. So that's the first thing to try.
If Internet Recovery is not an option in your situation, you sorta need a working Mac to revive a Mac with no bootable OS partition. From the working Mac you can go to the Mac App Store to download the latest OS (which comes as an installer app). Inside the OS installer app is a command-line tool called "createinstallmedia" that you invoke to create a bootable OS-installer partition on your USB flash drive. The full procedure is documented here: https://support.apple.com/en-us/HT201372
By the way, Mac disk images are Apple-proprietary .dmg files, not the simpler .iso format that was popularized by Linux. There might be ways to use non-Apple OSes to mess with .dmg files, but it's probably a lot of hassle, and you'd have to figure out how to do the work of the "createinstallmedia" tool by hand, which involves, among other things, copying certain files (which are required for booting) into certain special locations on the target volume.
