Install GRUB to usb thumb drive

Hi,

I'm trying to install grub to a usb thumb drive for a portable arch install. I've read the wiki for grub and installing arch on a pendrive but i'm receiving the following error no matter what i do.

sh-4.3# grub-install /dev/sdb
Installing for i386-pc platform.
grub-install: warning: Attempting to install GRUB to a disk with multiple partition labels.  This is not supported yet..
grub-install: warning: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
grub-install: error: will not proceed with blocklists.
sh-4.3# grub-install /dev/sdb1
Installing for i386-pc platform.
grub-install: error: cannot find a GRUB drive for /dev/sdb1.  Check your device.map.
sh-4.3# 

Anyone know what this means and how i can install grub?

Thanks.

Re: Install GRUB to usb thumb drive

You should chroot into your installation and then do the grub install.
Is a MBR or UEFI installation ?

I'm using arch-chroot on my desktop into the mounted install and running it from there. Its regular MBR

Re: Install GRUB to usb thumb drive

Then verify that your installation is corresponding with the UUID rather than addressing by kernel name.
What says

$ ls -lF /dev/disk/by-partuuid
