I created a bootable USB using rufus4.3 (build 2090) for Ultramarine Linux 38.
It is not being detected during startup, and I directly see the grub menu for the installed OS (Parrot 5.3).
(Similar situation as Why does my kali linux 2016.1 bootable usb not boot? but instead of Windows, it's Parrot)
I checked if the USB had the boot flag as per this (https://stackoverflow.com/a/15231218) answer, it does. I also did the same with the USB that I used to install the Parrot OS for comparison.
lsblk and fdisk -l screenshots attached below.
What I have tried:
- Secure boot off (was already off due to replacing Windows with Parrot, but double checked)
- Resetting UEFI settings (but secure boot kept off)
- Fast boot off
- Enabling CSM as per Boot from USB not working - Acer Aspire E1-522
- Disabling fastboot (https://superuser.com/a/512108/1366832)
- Set removable drive as boot option #1 (and parrot as the last boot option)
- Using all 3 available USB ports in case it was an issue with a port
Update:
I tried to boot using the USB on a 2018 Lenovo ideapad 320, and it was able to successfully enter live boot.
I tried using Rufus on the other USB (that had parrot) - same result
Using Balena Etcher instead of Rufus (both USBs) did not make a difference.
System Information:
