📕Installation Issues

Fix possible issues at the installation stage

The solutions described are not universal and may not work in your case. Use them at your own risk, and when you are absolutely sure in what you are doing.

No bootable devices detected

When trying to boot from the installation USB, you see the following or similar error:

You can try either of the solutions below:

Verify your download (always recommended). There is a chance the file was corrupted when downloading.
Make sure the installation drive is properly created. Mind that just copying the ISO image to the USB flash drive like a regular file via your file manager is not a good idea.
Try to create the installation USB with another writing tool. the recommended one is balenaEtcher, but you can use whatever you like (e.g. Rufus).
In the Latitude's UEFI settings (formerly known as BIOS), check that it is set to UEFI booting, maybe switch off references to legacy booting. Try to switch off Fast Booting (results in longer power on self test and other things, you want to enable fast boot again later). Most likely, the stick did not turn out well or the laptop is set to expect legacy boot.

Black screen when booting

You have downloaded the elementary OS image, created the installation USB, booted from this USB, and... see just a black screen with probably a cursor blinking in the top-left.

This issue could appear in case you have a discrete Nvidia graphic card on your device, and in BIOS, only the discrete card is enabled.

Unfortunately, Nvidia cards often happen not to work properly with Linux.

If your device has both discrete and integrated graphics, you can do the following:

When starting your computer, enter BIOS. As a rule, F2 is the key to enter, still refer to your device documentation to make sure.
In the Configuration tab (could be System Configuration or so), find Graphics Mode (Graphic Device or so) and select Switchable mode (Mixed, Hybrid or so).
Save changes in BIOS and exit.
Try to boot from the elementary OS installation USB again.
After you install the system, you can install and update Nvidia drivers, so the Graphics mode can be changed back if you like.

35% or 70% and then it stucks

There are cases reported that the installation hangs at 35% or 70% and does not move any further.

You can try the following to fix or work around the issue.

Verify your download (always recommended).
There is a chance the file was corrupted when downloading.
Re-start the installation of elementary OS with English layout selected by default.
You can add another keyboard layout after the system is installed.
If earlier you chose the automatic installation, you can try a custom one (see the screenshot below) to manage partitions manually.

Could Not Install error

Installation failed due to some reasons and there is a message Could Not Install saying that.

You can try the following to fix or work around the issue.

Verify your download (always recommended).
There is a chance the file was corrupted when downloading.
