Downgrade from Windows 10 to Windows 7

[sr16]

current os: win10 x64
the recovery files got deleted during disk cleanup. How do I downgrade from Windows 10 to Windows7? Also, will I lose my files? Will the files in drives(D&E)other than the system drive(C) be affected in any way?

Thanks in advance!

Since you "lost" (actually deleted yourself) the recovery files, you need your original Windows 7 install disk and product key. You should do a full reformat just in case, and you need to back up files before doing so.

Should I back up files on all my drives?

should always do backup.

Backups are always a good idea, though for this you only need to back up the files on the physical drive you are keeping in your computer to install Windows 7 on.

After opening up the W7 ISO, what do i select Clean Install or Upgrade(downgrade in this case)?

There is no downgrade from an ISO, do a clean install

You will only have "clean install" as an option when loading the disk (from a reboot). Just remember to back up your files first.
