Ventoy 1.1.18 Fixes a Windows Secure Boot Hiccup and Adds Experimental SteamOS Support
Your all-in-one boot stick gets a Secure Boot fix for Windows images and an experimental taste of SteamOS.
Picture this: you have one USB stick holding every operating system installer you own, and one of them refuses to boot because of a Secure Boot version check. Ventoy 1.1.18 is the update that deals with exactly that headache, and it opens the door to a few new boot targets, too.
The fix Windows users wanted
The most relevant correction for Windows people is a failed Secure Boot version check that affected Windows and WinPE images. If your rescue media or installer had been complaining on machines with Secure Boot enabled, this is the build to grab. Ventoy 1.1.18 also repairs intermittent Persistence failures on Ubuntu desktop, so live sessions that should remember your files finally do.
New tricks for the multiboot crowd
The headline addition is experimental support for SteamOS recovery images, a treat for handheld gaming fans who want a rescue stick that can serve more than one device. Linux remounting has been smoothed out so the ISO partition can be mounted out of the box on mainstream desktop distributions, and its device-mapper name is now the stable /dev/mapper/VentoyPart, which scripts can rely on. Clonezilla users gain a mountable ISO partition as well.
Compatibility roundup
A raft of distribution-specific adjustments rounds things out. Fedora 45 beta and Grml 2026.09 boot problems have been resolved, custom Syslinux-based ISOs are now supported, and compatibility with the latest LinuxConsole release has improved. VentoyPlugson now checks for Boot Conf Replace entries, and some Linux desktops no longer show duplicate disk icons in the sidebar.
Our verdict
Anyone who maintains a Ventoy stick for installing or repairing Windows PCs should update, because the Secure Boot fix removes a real roadblock on modern hardware. Linux hobbyists who juggle many ISOs will like the cleaner remount behavior. Steam Deck-style tinkerers can try the SteamOS support, but keep in mind it is labeled experimental, so do not make it your only recovery plan. Updating the stick means re-running the installer on it, so back up your ISOs first if you want to be careful.
