This laptop originally came with Windows. I removed Windows and installed Ubuntu. I’m now trying to install Clear but I get error: Wrong EFI loader signature.

EDIT: UPDATE

The solution ended up being related to a faulty USB device.

Is this the first boot from the USB image, or the second boot of the (newly) isntalled clearlinux?

3

Are you dual booting with Ubuntu? Is that the GRUB bootloader?

4

This is the first boot from the USB image (clearlinux has not been installed yet)

I want to overwrite Ubuntu. I get the error right after this screen:

I created the USB installer using Rufus (followed steps from clearlinux website). I also tried creating it with Etcher - same result.

UPDATE: I tried booting (using same USB installer) and got the following error:

I’m leaning towards the USB installer being corrupt… I’ve tried downloading and writting the USB many times with the same result though. Any suggestions?

First thing to try would be a 2-week old image instead of the latest one. It’s entirely possible there’s a bug with the latest version we haven’t spotted yet. Try maybe this one:

https://download.clearlinux.org/releases/32060/clear/clear-32060-live-server.iso

(server image should be quicker to try since it’s smaller).

A bad sector (that writes OK but fails to read) is another logical cause, but perhaps less likely.

Thanks for the help, @ahkok . It turned out to be my USB device. I purchased a new USB drive, downloaded the latest clear linux installer and everything worked perfect. Thanks for the help!
