Hi i am somewhat new to the linux env, this being my first install EVER(although i do have a fair amount of experience with Solaris) i chose arch because i like their philosophy.
I am try to dual boot with windows on a UEFI system with GRUB2, i have my partitions made, 1 for root, one for a swap, and another for home, i have mounted appropriately. i have mounted boot to /dev/sda1 the UEFI partition shared with Microsoft (I believe). the install works fine goes without a hitch, ive used os-prober to automatically locate windows and update the grub-mkconfig accordingly. But when i reboot it just reboots into windows and GRUB doesn't show.
I have two question for anyone who would like to answer:
1. is the mount to the boot partition correct?? - (clarification needed, but im sure it is)
2. does the boot ArchIso need to be booted in uefi mode??
i have tried to boot the ArchIso in uefi mode and all i see is a blank screen with nothing being booted!
a few specs incase they help
Laptop model: Asus N76VZ
motherboard: Intel HM76
partitions are made with gdisk, all are gpt partitioned.
I think the problem i have is not being able to boot in UEFI mode, but i jus need clarification, and also maybe someone has came across this blank screen problem?? Can anyone help me and point me in the right direction?

You need to register your linux install into the UEFI Bootloader with efibootmgr:
The difficulty is that you must be booted in uefi mode to be able to use it. So you must first be able to boot in UEFI mode.
For that you can either use UEFI Shell:
or use this trick:
cp /boot/efi/EFI/arch_grub/grubx64.efi /boot/efi/shellx64.efi
Reboot and launch EFI shell : Type reboot and press F2 and choose "Launch EFI shell from filesystem device" from the "Save and exit" tab. grub2 should be launched and you should be able to boot into your system.

ill give it a go later (kinda busy at the moment) and let you know the outcome!! cheers for the reply!
Wasnt able to use erfbootmgr because i wasnt able to run as uefi mode initially, but the uefi shell worked a treat!! Cheers
