Using a multiboot USB can cause your pendrive to become unmountable.
Using a multiboot USB can cause your pendrive to become unmountable.
You're facing an issue where your 32GB USB drive appears as an unknown binary and unmounts unexpectedly when using multibootusb on Linux. It seems the system is trying to add multiple ISO files at once, which can cause conflicts. There might be a way to resolve this without damaging the drive. Consider checking the file format or using a different method to create the bootable media.
This method won't permanently damage a pendrive. You can reformat it by setting up a new partition table and using various file systems such as parted, gparted, fdisk, cfdisk, etc. Remember, you can only work with partitions that have a supported file system on the OS, not raw drives like linux's default devices. When making a bootable USB, an ISO might be saved as a raw file, which means the drive could lack a proper filesystem depending on whether it contains a disk image. I don’t know much about multibootusb; it seems the site is unavailable. Here are some resources you might find helpful: https://mbusb.aguslr.com/ and https://wiki.archlinux.org/title/Multiboot_USB_drive. Your main worry is compatibility with Windows ISO files. Good luck!
