(version 1.26.27) I tried to decrypt the OS disk using the rescue disk, but I was afraid that it would select the wrong hard disk (I have 3 encrypted disks including the OS disk), so I rebooted to check from inside Windows11 (25H2) if the number was correct, and it wasn't !!!!!
RescueDisk EUI-64 is something like (not my real number): 32-8A-50-4C-01-85-A0-00 , while
Windows11 EUI-64 ( Powershell command: Get-CimInstance -Namespace root\Microsoft\Windows\Storage -ClassName MSFT_PhysicalDisk | Select-Object FriendlyName, UniqueId) is something like 32-8A-50-4C-24-85-A0-00 .
The fifth pair of numbers is different. From the "rescuedisk" boot line it is "pciroot (0x0)/pci(0x1,0x2)/pci(0x0,0x0)nvme(0x1,32-8A-50-4C-01-85-A0-00)", while from Windows this number becomes: 0000_0000_0000_0001_00A0_8524_4C50_8A32, or 32-8A-50-4C-24-85-A0-00.
Is this expected or is there a bug ?

How to check the EUI-64 provided by the VeraCrypt Rescue Disk:
Reboot using the USB flash drive with the Rescue Disk, select "d" - "Decrypt OS", then a list of disks appears. Type N if you just want to exit.
