Quick help with installing windows to SSD

I have win8.1
Do I just upgrade win8 to 10 on my hdd then create iso to my usb/dvd then install it to ssd. Boot win10 from ssd and delete the hdd partition

Deleting partition will remove windows 10 I had on hdd right? IS there anything I need to tweak in bios to make sure it will work ( other than set boot device to ssd of course)
 


someoen =e told me b4 that i should get win10 for licesnse key first. then go to ssd and sign in with my ms account
