I just moved on from Windows 10 to Ubuntu 17.04 Zesty Zapus one day ago. Everything is fine except the boot up time. In my Windows 10 my pc would take probably less than 10 secs to boot up. But in Ubuntu it is taking 2-3 mins to take me to the log in screen. I have run dmesg and it seems that something is getting wrong after 7 seconds. I'm attaching the result below. I also ran the boot process in cui mode and found that there was a hold for 1 min and 30 secs saying 'A start job is running for dev disc'. In other answers it has been provided that editing fstab file, checking for correct UUID will solve the matter but I have done with all this still the problem goes on.
I currently have one partition installed that is the entire disc (/dev/sda1). I did a clean install of ubuntu and erased the whole disc while installing. My configuration is 3 GHz intel Pentium dual core CPU, 4 GB RAM, 1 TB HDD with no other os installed except Ubuntu 17.04 with latest updates. I hope anyone could solve this problem for me. Thank you very much.
