I'm in the process of installing Kali Linux on a flash drive. I used Win32DiskImager to install the iso and then went into BIOS to boot to usb first. When I get to installing the GRUB I get the following error and when I click to proceed I get another error. I'm entering into my usb using UEFI mode. Sorry, I couldn't upload the images because I guess they're to large so I'll try to shrink them. The error message says "Install the GRUB boot loader on a hard disk Unable to install GRUB in dummy Executing 'grub-install dummy failed". Does anyone know what could be wrong?
