Maybe something about antivirus software or Windows Defender. Besides, you can delete all the partitions with other tools and then try again.
If you still fail after various attempts, it is recommended to use Ventoy LiveCD to install, please refer to Notes
This generally happen when boot Windows/WinPE in Legacy BIOS mode and is generally related to the screen resolution.
Use F5 Tools ----> Resolution Configuration to change the resolution before boot the image.
In most cases, choosing a smaller resolution will be better, for example 800x600x16 800x600x32 1024x768x32
In Windows, some processes will occupy the USB drive, causing Ventoy2Disk to be unable to gain control of the USB drive, and thus unable to list the devices.
1. Paragon ExtFS for Windows
ventoy.json should be placed at the 1st partition which has the larger capacity (The partition to store ISO files). Do NOT put the file to the 32MB VTOYEFI partition.
After install, the 1st larger partition is empty, and no files or directories in it. You need to create a directory with name
ventoy and put ventoy.json in this directory(that is \ventoy\ventoy.json).
The full path of the iso file (directories,subdirectories and file name) could NOT contain space or non-ascii characters.
Probably you didn't delete the file completely but to the recycle bin.
x86 Legacy BIOS and amd64 UEFI are supported in the same way
By default, Ventoy2Disk.exe will only list the device removable and in USB interface type.
If you want you can run from cmd
Ventoy2Disk.exe -U then all the devices will be in the list.
In this case you must take care about the list and make sure to select the right disk.
You can put the iso file any where of the first partition. Ventoy will search all the directories and sub directories recursively to find all the iso files and list them in the boot menu.
You can put a file with name
.ventoyignore in the specific directory. When ventoy detects this file, it will not search the directory
and all the subdirectories for iso files.
Yes. You can reformat it with exFAT/NTFS/UDF/XFS/Ext2/Ext3/Ext4 filesystem, the only request is that Cluster Size >= 2048.
You can use these commands to format it:
1. Format NTFS in Windows: format x: /fs:ntfs /q
2. Format UDF in Windows: format x: /fs:udf /q
3. Format Ext4 in Linux: sudo mkfs -t ext4 /dev/sdb1
4. Format XFS in Linux: sudo mkfs -t xfs /dev/sdb1
Secure Boot is supported since Ventoy-1.0.07, please use the latest version and see the Notes.
Most likely it was caused by the lack of USB 3.0 driver in the ISO.
