I have 3 partitions with windows 8 installed in the first one then i installed Ubuntu in the second one. By the end of the installation, my PC reboot on Ubuntu and doesn't show Windows8. So I run boot repair, but it gives me Windows Vista loader on
sda1 and when I click on it, it shows me a black screen.
I've been looking over 8 hours for a solution and I looked up to every thread about this problem, but no one worked for me.
