I just bought a HP DV6 6011tx (link) Laptop. I formated the disk through Windows and prepared for installing Ubuntu. But when I inserted the live CD, it showed the Ubuntu start screen and then everything went black. There was no cursor, everything just stayed black like the screen was switched off (but the system is running).
When I tried to install from the USB, it said
Live media is not found. Sometimes it also gave me a black screen like the CD. Does anyone have any idea how to fix this?
