 +==== Nao deu certo - Alternativas ====
 +Se o pendrive bootavel for baseado em Arch, como o System Rescue CD 6+ por exemplo, algumas coisas precisam ser substituidas, por exemplo o modprobe efivars que nao ira funcionar. No caso, esse link tem algumas sugestoes: [[https://superuser.com/questions/678976/installing-arch-linux-issue-with-modprobe-efivars]]
 +
 +Essencialmente a sugestao antes do chroot e que se rode o seguinte:
 +
 +<code>
 +#veja se existe o diretorio /sys/firmware/efi/efivars.
 +#provavelmente tem se vc bootou no modo UEFI do pendrive
 +
 +#rode um
 +mount --bind /sys/firmware/efi/efivars /mnt/sys/firmware/efi/efivars
 +</code>
