what does "keep nothing" in win 10 install mean?

[gsen]

HI,
So i have to perform a clean install of win 10 and i do not have a bootable disc and cant make one as my dvd writer isnt working...so ive decided too go with mounting the iso i have and installing from there
now my pc has three partitions...the c drive where the os is and other two drives
when i install the os it gives me an option of what to keep...and im rather interested in going with the "keep nothing" option...however does this option erase my entire HDD or just the partition where the OS is and clean install the OS there ?

Thanks

Just the partition with windows on it gets erased. teh rest of teh data is safe. BUt why aren't you installing from a bootable USB drive?

curious what it does if your documents etc are on another partition on same drive. I always assumed it wiped all drive but seems you right.
