error "unknown filesystem" on two old Laptops , desinfect2026.img - kreuter - 08-24-2026
My Ventoy-stick (1.1.17) boots on all my PCs, and starts any numer of ISOs correctly.
So I thought I had all the settings with stick formats, UEFI and Secure Boot settings right.
Now I am testing the new desinfect2026.img (virus scanner from German computer magazine c't).
It boots and runs from Ventoy as expected on all my wide variety of PCs, except for these two:
a Lenovo T420 Laptop, i7-2620M-CPU , 8GB RAM, latest UEFI-BIOS 1.53 from 2018 (Linux Mint 22.3 installed)
a Lenovo T420 Laptop, i5-2540M-CPU , 6GB RAM, latest UEFI-BIOS 1.52 from 2018 (Windows 11 25h2 pro installed)
where, right after selecting the image in Ventoy, I see a white-on-black-screen error message for a moment:
"unknown filesystem", then the screen erases and a blinking, unresponsive cursor remains.
It should be re-iterated that all the other images on the same stick boot flawlessly on these T420s, and the same stick (not a copy) has no issues booting desinfect on other machines.
When I create a "solo-stick", just the desinfect2026.img written to a USB stick without the involvement of Ventoy, it does in fact boot and run on these two old laptops.
Any idea what might be going wrong under Ventoy, or what I could do to help troubleshooting?
