[issue]: If I place an ISO in the VENTOY FAT32 partition, then the USB drive is no longer detected by the BIOS/UEFI. #2884
Comments
HP v165w 16GB is probably a fake USB drive (fake capacity) |
Hello, although it's a good take on the issue, I've used this USB countless times for many different uses, it's for sure not fake. |
Simple test - try a different USB drive to see if a different drive behaves in the same way. P.S. Just because you have used it many times does not mean that it isn't fake. |
Actuall its true, there is some sort of bug in ventoy (latest version) , due to which it isn't working on hp usb, my hp usb (2.0/3.0) is getting dismounted every time i install ventoy. |
Oh - so previous versions of Ventoy work Ok with your HP USB drive? |
Dude,
|
Just experienced the same issue on my SanDisk USB 3.2 Gen 1 64GB flash drive as well. Multiple reinstalls, upgrades, etc. didn't solve the issue, it would not boot on any device I plugged it into. Using the "upgrade" feature of the installer for Ventoy 1.75 (just the older version I had on hand) got me a stick that works just like it used to, so it's not an issue with the stick or my machines. |

What happened?
Hello, so I'm having a hell of weird issue with Ventoy.
I have an USB drive (HP v165w 16GB) to which I installed Ventoy on a Windows10 machine using the Ventoy2Disk app following this simple guide.
The Motherboard model is Gigabyte B85M-D3H-A
I have tried all these configs:
I also tried all the options on the UEFI; Legacy, UEFI, Legacy & UEFI, UEFI first, Legacy First, in terms of combinations I did not go all the way as it's a gigantic matrix of options (combined with the aforementioned Ventoy configs).
The ISO files I'm trying to use are:
Now, what I did find is that when I have the VENTOY (F:) partition on windows empty the BIOS detects the USB and I can even launch Ventoy, of course it says it has no ISO files. It is launching as 1.0.99 UEFI (Bottom left corner)
Now, whenever I load an ISO file in the VENTOY(F:) drive, the USB is no longer detected, which is absolutely weird.
If I remove the ISO file, then ventoy is visible again, therefore it's not writing over the boot sector.
One thing I noticed, using MiniTool Partition Wizard, is that the Ventoy EFI partition is set to the "end" of the drive, meaning that the VENTOY(F:) partiton is first, and then after that I have the 32MB VTOYEFI partition that holds Ventoy itself.
What is going on? I tried google for a while but couldn't find anything similar to my issue.
TL;DR: If I place an ISO on the VENTOY USB drive, it stops being detected by the BIOS. If I delete the ISO, then it's detected again by the BIOS.
