Ventoy: Create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI Files

The nice thing about Ventoy—and I didn’t fully appreciate this until I used it—is how simple it makes bootable USBs. You just drag and drop ISO images onto the drive, and it can hold as many as will fit. When you boot from the Ventoy USB, you just pick the image you want to install or run—no re-flashing, no fuss.

It’s honestly wild how convenient it is. Ventoy was the only method that worked for me when I needed to install Windows alongside an existing Linux setup for dual-booting. Everything else I tried failed, but Ventoy handled it perfectly.

I would love it if it worked well, but it's been really flaky for me. Maybe half the ISOs work, the rest get various errors on boot and fail. These are Linux ISOS, too, which I would have expected to work.

Am I doing something wrong?

How are you creating your Ventoy drive? I would recommend using GPT. Also be sure to boot your drive in UEFI mode. Finally, be sure to update Ventoy to the latest version, they release regular updates with bugfixes for compatibility issues with various ISOs.

Perhaps this is obvious to many in this context, but this refers to the partitioning scheme for the disk—not the LLM service.

ChatMBR.

I've replaced all my GPT disklabels with Sun disklabels because I refuse to let them talk.

UEFI still boots. Spec said it can boot from fat in an eltorito floppy image and sun disklabels sit in the second or so sector. Spec also said it abstracts the type of volume so all boot methods always work for all drives. ISO images don't use the first 4kB so it doesn't see there's disklabel at all

So now I can mount the ssd as iso9660 but there's also partitions on it of which the third spans the entire drive (of course, because that's the c partition)
