Trying to install, booting into grub

I’m trying to install Qubes from a USB stick but I only get to a black screen that says the following:

Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file complitions.

grub>

Secure boot is disabled.
AMD SVM is enabled.
Boot mode is on Legacy Support with Boot Priority being Legacy First (then UEFI).

I installed Qubes before on this laptop and it worked fine, not sure what’s going on here.I tried installing both 4.2.1 and 4.1.0. I currently have Windows 10 installed on this laptop, Ubuntu and Pop!_OS have also been installed in the past.

Thanks for any help!

I resolved it myself by creating the installation stick with Balena Etcher instead of using the command line as described here: Installation guide | Qubes OS

sudo dd if=Qubes-RX-x86_64.iso of=/dev/sdY status=progress bs=1048576 conv=fsync

No idea why it works now but it does.
