Through following a tutorial to make a bootable Windows USB from Ubuntu 14.10 using PC that use BIOS, I opened terminal and run
sudo grub-install --target=i386-pc --boot-directory="/media/ihab/windows/boot" /dev/sdb
to use GRUB for making USB bootable, I should see if everything is ok
Installing for i386-pc platform. Installation finished. No error reported.
But the actual that I got this message which I couldn`t know what to do then
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.
This should be following the tutorial mentioned here
