Follow the steps indicated below to install Ubuntu 14.04/15.04 on your Dell computer and configure the BIOS to use SHIMx64.EFI (Required for normal operation):

1. Download and create a bootable Ubuntu Linux USB drive. (You may want to use a third-party application like Rufus to create the bootable USB drive.)

2. Once the UBUNTU install from the USB drive is finished and you reboot the system, Press F2 when you see the Dell logo to enter the BIOS. Once in the BIOS, choose Boot Sequence.

3. In the boot sequence screen that appears, click the Add Boot Option button. The Add Boot Option window appears. Type a name in the Boot Option Name text area (Ubuntu for example). Click the button to the left of the File Name text area. The EFI Boot Selection window appears. (Figure 4)
