Fresh install crashed at grub installer

[Arnaud Thevenet]

Install crash with beta 14.04.
No similar issue happened on this computer with previous ubuntu versions. 13.10 always installed normally and nothing changed in this PC.
I have a 40GB SSD a system drive, and 750GB HDD as data drive. The grub was supposed to install on the SSD but crashed.

please find the last message attached as a screenshot. This means "unable to find the EFI directory".

I tried with english language, the same happens. "cannot find EFI directory". My SSD partition table is msdos, not GPT, but with GPT table, the same happens.
