The issue as follows: I have a machine setup to dual boot with Windows 7 and ZorinOS. I’ve been meaning to try other distributions and created a bootable flash drive with PopOS using Balena Etcher. However the the USB is not recognized during boot process and cannot run it even to try it out.
After much back and forth these are some of the things I have already tried:
- Tried other USB ports in the machine.
- Tried other USB drives.
- Tried using another computer, where it does work as expected.
- Tried a different ISO file other than PopOS to confirm the ISO is not the issue.
- Tried using Rufus (from Windows 7) instead of Etcher, selecting MBR partition scheme.
- Tried using
fdiskto manually modify the partition types on the bootable flash drive from “EFI (FAT-12/16/32)” to “W95 FAT32”
- Tried running
boot-repairwith the default recommended repair mode (Generated report)
Aside from the fact that I cannot boot from this flash drive, everything is working great. The fact that I can try out PopOS (and other distros) from another computer makes me think this is an issue with the BIOS or something related to the boot process. Unfortunately this is already far beyond my experience, does anyone have any ideas what this could be and how to fix it?
Any help is much appreciated!
