i fisrt installed ubuntu 15.04 with encrypt disk, the installation finished fine but when i try start ubuntu it ask me for a password, i enter it and then it did not do anythink.

then i try install ubuntu 15.04 in normal mode (without encrypt disk) but when the installation was finishing it crashes.

note: when the installation ask me for my location this autoselect Bogotá (that is correctly) then i select 'next' and an error appear. the first installation i was select 'try again' and it continue and finished fine. the second installation i was select 'try again' but the same error appear again, then i select 'ignore and continue' and it continue but when it was finishing it crashes.
