I’m having issues with the USB installer on a Dell XPS 13 9370. I get
Wrong EFI loader signature error (see image below).
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.
- SATA Opearation > AHCI
- Secure Boot > Disabled
- Advanced Boot Options > Enable Legacy Option ROMs
- 8th gen i7
The solution ended up being related to a faulty USB device.
