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?

Probably not, UEFI boot is terribly fussy and I haven't seen any sort of UEFI image loader similar to memdisk that works for BIOS boot. There's an optional standard for loading images, but I don't think any of my firmwares support it; and I'm not sure if the loaded image is available after boot services terminate anyway.

Linux images have to be processed to pull the kernel and initramfs images out, rather than booting an image, and then if the image used a filesystem after boot, hope it finds it. (This is even messier for PXE, at least with USB, you have a fighting chance)
