Hey Guys,
i'll try to use Ventoy to install my firewallsoftware opensense. first it boots correctly, but at one time its looking for an CD/DVD-ROM device to mount, at this point it breaks up because Ventoy maybe does not emulate this correct?
opensense is based on freeBSD and starts at a live-system at the first point there looks it good after the bootscreen of opensense you can chose to boot up as single user or multiuser system or an rescue mode (if i remember correctly) at this point is anything ok.
After it starts to bootup it goes into the live mode and fails at the point when it mounts up the filesystem from the CD/DVD-ROM it fails because there is no hardware CD/DVD to find and no CD/DVD-ROM device.

after all, i love it to use ventoy because i have less time with flashing an iso to USB stick anymore so please work on it more it's the best tool i have ever found on the web!

greets

New to Ventoy and already a fan.  The part that pulled me to Ventoy over anything else, including hardware based ISO emulators, was the auto_install plugin, essentially raising Ventoy above simple ISO booting to a full fledged kickstart.  A a question on auto_install, however: once I configure a auto_install entry does that create a unique grub entry or does it mean that every time I attempt to boot the ISO configured it always uses the kickstart script?

Seamless transition between multiboot systems.

I know you haven't added that support yet because you don't want a headache with users losing their data and blaming you, but I don't see why not adding a parameter to resize and install Ventoy keeping current data. You just need to make it clear that the user is responsible for any data loss. Today I did it manually on my external HD and it worked perfectly, if anyone wants to try it, here are the instructions:

To boot with UEFI:

1. Install Ventoy on any flash drive and make a dd backup of the second partition EFI that Ventoy created on the flash drive
   
   Code:

   sudo dd if=/path/to/the/part2/of/ventoy/flash/drive of=part2-EFI.img
   
   
2. Resize the NTFS partition of the external HD using Gparted or any similar tool, leaving 32MB at the end of the disk and then create an ext4 partition in that space (on the first attempt Gparted failed because my NTFS partition had some errors, I had to restart on Windows first and run the command "chkdsk /f /x H:" on my external HD to correct these errors).
   
3. Restore the dd backup of the second partition EFI on the second partition that you created before
   
   Code:

   sudo dd if=part2-EFI.img of=/path/to/the/part2/of/external/hd
   
   

1. First you need to follow all the steps for UEFI
   
2. Backup the first 1MiB of a flash drive created by Ventoy
   
   Code:

   sudo dd if=/path/to/ventoy/flash/drive of=VentoyMBRandGAP.img bs=1MiB count=1
   
   
3. Backup the original MBR of the external HD as a precaution in case something goes wrong
   
   Code:

   sudo dd if=/path/to/external/hd of=OriginalMBRandGAP.img bs=1MiB count=1
   
   
4. Backup the original partition table of the external HD
   
   Code:

   sudo dd if=/path/to/external/hd of=OriginalPartitionTable.img skip=446 bs=1 count=64
   
   
5. First you have to check by GParted that your first partition starts in sector 2048 (1048576 bytes). If yes, you can restore the VentoyMBRandGAP.img to the external HD
   
   Code:

   sudo dd if=VentoyMBRandGAP.img of=/path/to/external/hd bs=1MiB count=1
   
   
6. Restore his original partition table
   
   Code:

   sudo dd if=OriginalPartitionTable.img of=/path/to/external/hd seek=446 bs=1 count=64
   
   
7. Use fdisk to change the partition 2 type and set the boot flag (you need to paste all lines at once on terminal and press enter)
   
   Code:

   echo "t
2
ef
a
1
w" | sudo fdisk /path/to/external/hd
   
   

The most common failure I find for isos is "No bootfile found for UEFI!  Maybe the image does not support X64 UEFI."

Is there  a workaround?

I have a PC a rather old Advent laptop with Intel Dual-Core T3200 64 bit processor.
I can use Etcher to put a Linux Mint iso onto a USB stick and get the PC to boot from it
However, if I reformat the USB with Ventoy (1.0.10) and put the Linux Mint ISO on it, the PC will not boot from it. It doesn't show the Ventoy selection menu, it just moves onto the next bootable device.
If I use this USB with Ventoy on a different PC, it boots Ventoy and then Linux Mint without a problem.

Clearly the PC can handle the USB stick.
Also, the Ventoy installation on the stick is OK.
But, the PC is unable to handle Ventoy as a bootable media.

Any suggestions how to find out what is wrong?

Hey, thanks for a great tool that's much more user friendly to use than what I've been using previously.

Been testing it out and for the most part it works great, but Ubuntu Studio 20.04 does not boot.
