![]() ![]() Isolinux or boot/isolinux are two popular locations to check boot configuration. ![]() ![]() Let's mount the iso image and check the configuration we need for a successful boot: $ sudo mount -o loop /path/to/iso /mnt/ isoscan/filename - we need the path for image boot menu.The only one way is to dive deeper into the image itself and figure it out. Sometimes there's a task to boot not popular image and Internet isn't helpful. Now time to unmount the flash drive and reboot for testing.

Secure Boot: Ventoy still loads unsigned executables.So, why do we still need Grub? There are several reasons: Ventoy, another popular Open Source tool made by Chinese developer Hailong Sun, does the job really straightforward and doesn't need any dancing with configs. GRUB is the standard Linux bootloader for decades, and also supports other operating systems. 3 min read Photo by Arun Prakash / Unsplash Why GRUB.
