On my system I have windows 7(64 bit) and ubuntu 12.04(32bit) already installed. I had to install this old ubuntu only because at that time I was not able to install 14.04 and I had given up at that time.
Recently I tried downloading ubuntu 15.04 64 bit for my desktop machine and burnt dvd as an iso file.
When I tried booting and installation, it always waits there at the screen where it asks for language. After pressing continue, nothing happens.
When I pressed quit, it went to trial mode and there as well, I tried to do installation but again it halts there only.
After that, I tried installing same on vmware and I was able to do installation successfully there so its not an issue with image for sure.
I am not sure how can I see any debug logs or anything. It would be great if someone can help here.
If there is anything I need to do with hardware, I may try if someone can guide how to check any configurations.
