Dell Precision 7720 grub2 bios setting

good afternoon all
i bought an Dell Precision 7720 a huge upgrade from my 2008 HP Pavilion dv7,that still works well.
but i wonted to do other things vm's, video editing ....

it came with a 2tb ssd, so i shrunk win 10 and created a partition for /.
so i install arcolinux openbox iso . everything went fine calamares finished without any problems, reboot and it went right into win 10.
i looked at the /dev/sda and nothing pertaining to Linux had been added.

now arch wiki states it wont's to have a 300 mb boot partition.

so i pulled the 2tb ssd and install a 60 gb ssd.
booted in to bios and this new ssd did not show up, well i forgot this device had been wiped.
so i booted my usb and formatted my ssd with gparted.

set the partition table to gpt

/dev/sda1 boot flag 300 mb
/dev/sda2 swap 16 gb
/dev/sda3 ext4 (rest of the drive)

install went fine , rebooted it says it can't find any boot media.
i messed with all the setting in the bios. still isn't working.
parted /dev/sda disk_set pmbr_boot on (tried that no.)

so i though i had messed up fooling with the bios, i switched the 2tb ssd back in laptop and wala i didn't have to do anything booted right into windows.

i did not like a 2tb hard drive so i ordered 2x 512gb m.2 pcie 2280 cards
i'm hopping i can put win 10 on one and linux on the other? maybe

any ideas ?
