Sorry I am a little confused on the topic. I have an asus essentio series with asus uefi bios utility and I tried installing linux on the hardrive by creating a "/boot", "/" root, and swap partition. I have successfully installed the linux operating system but the grub menu only shows up when I have the usb plugged in. I was hoping that linux or the grub menu could be accessed from the bios utility similar to how windows 10 can be. But it doesn't show there, when I hold shift at the start screen to force boot grub it works but it only works with the usb plugged in, otherwise it tells me to insert a boot media because it doesn't detect linux or grub. Im sure there are similar issues somewhere on the internet but I have failed to find one that properly explained the issue, When I load linux from the usb everything works fine as if it was installed on the computer. But it just doesn't allow me to dual boot or boot in general unless that usb is plugged in.
I did install windows before attempting to install linux

What I would like is for it to boot grub or linux os directly from the bios or at least display grub menu at pc startup without the usb needing to be plugged in. If I wanted to make a plugnboot usb I would have just launched the usb with persistence and I wouldn't have installed linux on my hardrive. I assumed that because I have reserved a space for the linux OS and grub that it would boot from there but nope. :( Any clue what I did wrong?

On my boot options I have this displayed
asus sh-224DB -This was here origionally and does nothing as far as I know but boots linux when usb is pluged in.
Windows Boot Manager (P1: TOSHIBA DT01ACA100) -Boots Windows.
PO: TOSHIBA FT01ACA100 (953869MB) -Boots Windows unless usb is pluged in it'll boot linux.
SanDisk Cruzer Glize (14907MB) -Linux usb
UEFI: SanDisk Cruzer Glide (12907MB) -Linux usb in UEFI.
Also sorry that I failed to mention the linux OS that I installed is Kali. Not trying to cause any chaos here just trying to find a solution to my issue.
