Install Grub when ssd is hd1

I have a Dell G3 17 3779 laptop.
It has sata HDD as hd0 and m.2 ssd as hd1. Both in GPT. I deleted everything in the ssd and installed Windows 10.
I used 4 partitions: - Windows recovery environment (499M) | /dev/sdb1 - EFI System (100M) | /dev/sdb2 - Microsoft reserved (MSR) (16M) | /dev/sdb3 - Main Windows NTFS partition (70G) | /dev/sdb4 Also I added for Arch Linux 2 partitions: - For / (47.7G) | /dev/sdb5 - For swap (980.3M) | /dev/sdb6 HDD disk has 2 partitions: - Microsoft reserved (MSR) (16M) | /dev/sda1 - Some NTFS (900G) | /dev/sda2 After Windows I installed arch linux from UEFI following the wiki manual. GRUB was installed with the usual grub-install without keys I tried to configure GRUB with manual config: */boot/grub/grub.cfg* . $prefix/menu.cfg */boot/grub/menu.cfg* set default=0 set timeout=10 menuentry "ArchLinux" { linux /boot/vmlinuz-linux root=/dev/sdb4 rw initrd /boot/initramfs-linux.img } menuentry "Windows" { regexp -s root '\((.+)\)' "$cmdpath" chainloader /EFI/Microsoft/Boot/bootmgfw.efi } After rebooting just started Windows 10 without any boot menus. I installed os-prober and tried grub-mkconfig and get some warning like:
WARNING: Failed to connect to lvmetad. Falling back to device scanning.
or
WARNING: Device /dev/loop0 not initialized in udev database even after waiting 10000000 microseconds. Instead /dev/loop0 was in all partitions. And still booting only Windows. May be it because my HDD is first in BIOS unlike SSD (hd0 vs hd1)? How to fix this problem? *update:* this answer https://askubuntu.com/a/816347/879272 allows me to open grub. But why BIOS started EFI/Microsoft/Boot/bootmgfw.efi ignoring another boot loaders.
Can I disable this behavior?
