This question already has an answer here:
Currently I am using Windows 8 in my dell N4050 machine. It has 4GB of RAM, 320GB HDD. Now I want to install ubuntu 13.04 alongside Windows. I tried several times after reading some blogs. But every time I failed.
I downloaded Ubuntu 32bit from the official site and made my pendrive into bootable device using Universal-USB-Installer-22.214.171.124.exe.
I could not burn a DVD and boot from it because my DVD drive is not working somehow.
By the way, I did all the normal stuff what is needed for installing Ubuntu. In installation process
Install ubuntu alongside windows 8 should have appeared but I just saw
Replace Ubuntu with Windows 8 and
Something else. Then I tried going with
something else, I did not see such option where I can chose to use ubuntu alongside windows.
