Don't know what is happening but laptop boot directly to Windows (only 
appears manufacturer splash screen and then manufacturer splash screen 
loading Windows), bypassing GRUB, (I don't know how can do it if there's 
no more bootloaders installed and MS's is removed). It seems that GRUB 
doesn't intervene. I tried pressing n times Esc and in another boot 
Shift, and don't happens anything.

When works correctly, appears manufacturer splash screen, GRUB, if you 
select Ubuntu (black screen until loads) and Windows (manufacturer 
splash screen loading Windows).

I done workaround again to view GRUB. set command:

locale-dir=(hd0,gpt7)/boot/grub/locale
prefix=(hd0,gpt7)/boot/grub/
root=hd0,gpt7
(this variable doesn't appears) saved_entry=
secondary_locale_dir=
