 Installation using an ISO image
 ###############################
 
-Burn the installer:
-	For x86 architecture you can burn the ISO directly into a usb drive using
-	`etcher <https://etcher.io/>`_ or  dd linux utility. If you have a CD-DVD
-	burner, you can burn the ISO into an optical media then boot from CD or DVD.
-	Etcher can also be used to transfer arm images into SD cards.
+Burn the installer
+------------------
+	For x86 architecture you can burn the ISO directly into a USB drive using
+	`etcher <https://etcher.io/>`_ or  dd linux utility::
 
-Boot the installer:
+	$ sudo dd if=xxx.iso of=/dev/sdX bs=4096
+
+	If you have a CD-DVD burner, you can burn the ISO into an optical media
+	then boot from CD or DVD. Etcher can also be used to transfer arm images
+	into SD cards.
+
+Boot the installer
+------------------
 	For x86 architecture, enter BIOS configuration, select to boot either from
 	USB or CD and reboot. ARM images are ready to go, so boot from sd card and
 	wait for the initial setup to complete. This takes around 30 minutes in
 	slow devices like Raspberry PI.
 
-Installer:
+Installer
+---------
 	The current ISO installer is reduced to have minimal interaction. You will
 	prompted to select location, language and root password. The installer will
 	pick the first available disk to deploy the the OS. Once the installer
 	finished the system will reboot, make sure you remove the installer and
 	select BIOS to boot from the disk where |omv| was installed. You can also
 	start connecting any data drives you previously disconnected before install
 	or reinstall.

+Troubleshooting
+---------------
+
+The error `Unable to install GRUB in /dev/sda` occurs.
+	In this case execute the following steps:
+
+	- Select `Continue` in this window and also on the next which says
+	  `Installation step failed`.
+	- In the Debian installer main menu (which should have popped up by now),
+	  select `Execute a shell` and then `Continue`.
+	- Execute the following commands::
+
+		# Chroot.
+		chroot /target
+		# Replace [a-z] with the drive you want to install grub to.
+		# This is normally the drive you've selected to install OpenMediaVault on.
+		grub-install /dev/sd[a-z]
+		# Update GRUB.
+		update-grub
+		# Exit chroot.
+		exit
+		# Exit shell.
+		exit
+
+	- Select `Continue without boot loader` in the Debian installer main menu and
+	  then `Continue`.
+	- It should now continue the installation successfully.
