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:

  1. exFAT/GPT/SecureBoot
  2. exFAT/MBR/SecureBoot
  3. FAT32/GPT/SecureBoot
  4. FAT32/MBR/SecureBoot
  5. FAT32/MBR/NON SecureBoot
  6. FAT32/GPT/NON SecureBoot

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:

  1. OpenMediaVault (700MB)
  2. Lubuntu 24 (3.04GB)

 

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.

HP v165w 16GB is probably a fake USB drive (fake capacity) The first say 4GB may exist, but the other 12GB are probably non-existent and the space is mapped to the first 4GB. When you add an ISO, it writes to the first 4GB and overwrites the small Ventoy Ptn 2. Try a different USB flash drive or test it with FakeFlashTest.exe or Validrive.exe

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.
Furthermore, when I remove the file from the ISO, Ventoy appears again in the boot list, therefore it's not being overwritten

Simple test - try a different USB drive to see if a different drive behaves in the same way. Try another computer/notebook You could also try a VM or emulator. MobaLiveCD and RMPrepUSB both use QEMU which you can use to boot from the Ventoy USB drive under Windows

P.S. Just because you have used it many times does not mean that it isn't fake. e.g. My gallon bucket has a hole in the side about 3/4 of the way up. I have used it hundreds of times and it will hold 4 pints of water and never leaks so it must be good!

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. I t does work on other usb like sand disk however it keeps messing up in hp usb, i tried it on my friends laptop, and there was the same issue. Hope ventoy fixes it in next update.

Oh - so previous versions of Ventoy work Ok with your HP USB drive?

Dude, fine, the world is filled with morons but I ain't one that comes around and puts 3h trying to figure what is wrong with Ventoy and why is behaving like this, without covering the bases.

But, given that you have mentioned several times and insisted on the "Your USB is fake and you never even used it full" (I did); I ran the FAKEFLASHTEST v1.1.2 and this is the result: image

As you can see, it's not fake, the device is fine, it's ventoy that has some hiccup on it.

I ended up following your suggestion and used a sandisk cruzer glide 32gb and ventoy with ISOs on the partition was detected fine. But the HP issue, still remains. Hence I'll leave this open.

Bests,

Dude,

  1. Ventoy is used by MILLIONS of people - if it had such a bug then other people would also be complaining
  2. Only your one particular HP USB drive has this issue - you just proved this
  3. FakeFlashTest is a quick capacity test to detect USB flash drives which report a fake capacity, it does not thoroughly test the drive and it does not prove that your USB drive is not faulty in some other way - Also test the HP with H2TESTW, VALIDRIVE, CHIPGENIUS and finally fill the drive up completely with video files and then play each video. https://rmprepusb.com/tutorials/007-all-about-fake-sd-cards-and-usb-flash-drives/ https://rmprepusb.com/tutorials/007-all-about-fake-sd-cards-and-usb-flash-drives/#HOW_TO_TEST_A_SUSPECT_UFD_OR_SD_CARD

Just experienced the same issue on my SanDisk USB 3.2 Gen 1 64GB flash drive as well. Previous versions worked fine, then I installed the ARM version of 1.99 which also worked fine, but upon installing the x86/64 version onto my flash drive it would simply hang every boot before displaying anything.

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.
