I have burnt Ubuntu ISO to a USB. When I boot from it, my laptop shows a black screen with a cursor blinking on top-left. This cursor keeps blinking endlessly. I left it overnight once to confirm that it doesn't change. I tried installing Ubuntu in another laptop after this incident with same USB and I was successful in doing so. This blinking cursor appears as soon as I choose the pen drive from Boot Menu or if it is at the top in Boot Order in BIOS. I have tried both 32 and 64 bit versions. If I remove the pen drive and boot from hard drive, Windows boots up perfectly. I was able to burn Windows ISO to this USB and install it successfully.
What is the solution to this? The entire thing happens just after booting from USB (even before anything related to Ubuntu would show up).
Wubi is an option which I am trying currently but it is only a temporary fix as it supports only upto 30 GB hard drive. I want to completely remove Windows.
The Ubuntu version I have tried is 14.04 LTS (32 and 64 bits). I have tried booting from all USB Ports.
Laptop is HP Pavilion i5.
