[Trisquel-users] GRUB Won't Boot System

[superbyelich]

Hey all,

     I just ran an apt-get update on a friends laptop and when it restarted  
it seems to be booting ok, gets to the grub screen where you can select  
Trisquel or Advanced options, but then goes to a GRUB Login/Password prompt  
instead of booting the system.  Any ideas?

Thanks,
