It is normal for Ubuntu installation to remain at the "Detecting File Systems" stage for long? I followed all the steps as recommended, I have created the partition "/" and "Home", I am now waiting on the installation window while I get the message "detecting file systems". It's been about two hours.
Installing Ubuntu 14 from a DVD.
No.
I had the same issue - my system is a Dell G3 SSD-HDD hybrid, so I will tell you how I fixed it for my system.
Enter BIOS and select to boot with your external drive.
In the options, select any of those using arrow keys from Try Ubuntu or Install Ubuntu
Instead of pressing Enter/Return, press the letter e.
Now - type out acpi=off after quiet splash, and backlight=vendor before it.
Then press F10.
Now the issue should repeat itself. After clicking 'Install Now', you should have 'copying files' now.
