In my version of grub2, I've modified the source code of ventoy module, and it can be used in any filesystems. grubfm+ventoy (https://github.com/a...ager/issues/197) should also work on ntfs / fat partitions.But ventoy's script in linux initrd may not work on non-exfat partitions.
a1ive Ventoy option works for Boot Image located on FAT32 Or NTFS which is GREAT but not yet in all cases ....
Just tested a1ive Ventoy option for Linux ISO located on NTFS partition of USB Portable SSD made with USB_FORMAT.
Ubuntu and Fedora and runtimelivecd.iso FAIL (the same as when located on FAT32 drive).
