[ubuntu-studio-users] install broeken?

[jibel]

Hi ,
I can't understand the reason why ubuntu-studio is broken just after his 
install and  the restart PC studio is not start: blank screen
  I think to have make that perfectly , but I thing , may be to make an 
error ?
because I have stopped the install just before his complete install ?? 
too long for my opinion in the last stage more/less 15 mn after the 
install (the blue bar down is complete) for close the install windows !
May be it's the reason why for the failure , can you tell me your 
opinion about this subject
best regard   Jibel :-!
