grub-install with target i386-pc in 64bit machine

Dear friends,
while installing grub, I have done --target=i386-pc as I am not aware of correct target for me.
I have a 64bit machine,
$uname -rm
3.6.11-1-ARCH x86_64

can I change it now? and should I change it?

Welcome to Arch.  We have an excellent wiki which should be consulted before posting common questions.

https://wiki.archlinux.org/index.php/Gr … fi_package

Failing that, google is an excellent source, for example: http://lmgtfy.com/?q=grub-install+target

Welcome to Arch.

Googling for "grub install target" returns the Archlinux wiki and this post.
From the only reply to this thread one might deduct that you need so specify --target=x86_64-efi for 64-bit system.

I found that this is not necessarily required for 64-bit systems.

As long as you don't use UEFI, I don't know if it is needed to use  --target=x86_64-efi for 64-bit system.
I chose --target=i386-pc, and on boot GRUB gave the option to choose x64 or i686 kernel

This wiki has some details about the --target options: https://wiki.gentoo.org/wiki/GRUB2_Quick_Start
Maybe someone with more insight can give more details on when to use what.

i386-pc is fine for grub2
The kernel takes over and runs x86_64 given you are using 64-bit kernel.  You could use the 32-bit kernel on 64-bit, but probably more stable on 64-bit.
