Take the 2-minute tour ×  I just downloaded the lastest Version
of Ubuntu13.04 from the official website(of course it is
amd64)and my Computer is the ASUS-A45V Laptop.I used the
universal usb installer to creater a boot usb disk for
installing ubuntu.And first i tried to use the first default
option to install it(that means i let ubuntu to do all the
things itself,and i have Win7 installed on my HDD),and all the
things seems runs very good.but, then when i reboot and try to
start ubuntu.It told me that "Faild to mount /boot/efi, type S
to skip it, or type M to fix it manually"and then i check the
/boot/efi folder ,and find that there is nothing in it! And then
i tried to install it manually,but got the same result. Whats
the problem? How can i fix it?and whats more, Boot-Repair can
only bring my Win7 loader back in the Grub list but the formal
efi loader of Win7 has been overwrited into Grub by Ubuntu. How
can i restore it?  share|improve this question add comment  1
