ventoy is awesome, my tip for OP is to always have a live usb in case of emergencies. you can just install ventoy onto a USB and drag and drop your bazzite ISO but having a live stick you can plug in and boot from at any moment is 100% a life saver. whether you broke something or you just wanna troubleshoot (think windows safe mode but better) you'll be glad you kept that USB lying around :)

i would suggest looking into alternatives to Ventoy, as the community has been actively discussing the 'blobs' of precompiled code. What this code does is unknown so you are trusting that there is nothing that could be harmful. I personally wouldn't trust it until the below thread provides more clarity.
