How can I use Two Operating systems(Win 10 and Win 7) on Acer Predator Helios 500 ?

Hi!

I want to use Win 7 in second Hard drive of Acer Predator Helios 500 . Default Window in SSD of Acer Predator Helios 500 is Win 10. And Boot priority of Predator Helios 500 show only Window Boot Manager . So I can not set Hard Drive(drive D) as first boot priority . At Acer Predator 17, default setting of  boot priority order show many drives list (HDD0,HDD1,HDD2,USB HDD, USB CDROM) and can use different two windows ( drive C and drive D) by changing Boot mode  UEFI and Legacy.

So, What do I need to do and configure step by step in BIOS setting of Acer Predator Helios 500 to use two different Windows?

Thanks,

technically yes but it should be a bit tricky the best option should be the 7 installed first and then the 10 but you should be able to do it backwards too create a win7 uefi usb installation and give it a shot (in another driver or partition of course) see if it detects it properly and if u don't get any bsod during the installation if u get it means your best option is to go for legacy mode instead of uefi but the installed win 10 will not boot anymore and someone correct me if im wrong but u might need to go to sata ahci mode to be able to run 7 it wont run in rst optane mode my bios doesn't have those options i can't even change the sata mode it's locked so it's a bit of a nightmare to get dual boot
