Recently after trying to upgrade Ubuntu 13.10 to Ubuntu 14.04 my laptop will boot up until the grub menu and after selecting my OS it would just give me a black screen with a underscore at the top
The problem seems to have something to do with the graphic drivers from what I've been able to find.
Computer Model:Dell Inspiron 1564 Processor: Intel core i3 System Chipset: Intel HM55
If you were using the proprietary drivers you may need to revert to the open source drivers, and then you can experiment with re-enabling them.
During the boot, hold down Shift This will get you to the Grub boot options screen. From there, you will want to choose 'Network' which takes a while to complete, and 'Root' which will drop you into a tty terminal.
From there, the procedure in how-do-i-remove-the-proprietary-ati-drivers will remove the ATI drivers and load the open source drivers.
