Headaches getting hardware created after Win 7 was last updated to work on it. Win 7 has no drivers for any of it, Maker didn't make them either. PC is too new.
generally its a better idea to put win 7 on before 10 as doing it the way helpster suggests will mean neither OS knows the other is there and booting between them will be annoying.
What laptop is it? Does it have win 7 drivers? If its only new you might find it can't even run win 7.
unplug the ssd, install win7 on the hdd
replug the SSD and try booting from the SSD, boot priority in BIOS
Dear helpstar,
i did that, but when laptop restart , it has messenger "selected boot image did not Authenticate. Press 'Enter' to continue".
so, sucure boot: disible. laptop can start win 7. However, starting window doesn't finish.
Ps: i don't connect SSD.

Omen by Hp 15 enery star, win 10 home. I haven't yet checked driver for win 7. new laptop.
when win7 is installed, replug the SSD. Win10 should boot if 1st boot priority in BIOS is set to your SSD. Afterwards you can use tools like BCedit, to get a dual boot menu
