System Partitions Encryption W7 + W10 - Multiboot UEFI

[Maverick]

Hi,

I have 1 hard drive with Windows 7 and Windows 10 with multiboot.

After encrypting W7, i moved \EFI\Veracrypt to \EFI\Veracrypt_W7
and created the new entry on the UEFI boot list pointing to it.

All good so far, i can boot to my new entry "Veracrypt bootloader (W7)" password accepted and Windows 7 boots ok.

After encrypting W10, i moved \EFI\Veracrypt to \EFI\Veracrypt_W10 and created the new entry on the UEFI boot list pointing to it.

All good so far, i can boot to my new entry "Veracrypt bootloader (W10)" password accepted and Windows 10 boots ok.

Now, if i select "Veracrypt bootloader (W7)" password is accepted if i select Windows 7 on the windows boot list doesn't boot, if i select Windows 10 it boots ok.

I notice that the number that is shown after password is accepted was higher for Windows 10 then it was for Windows 7, and doesn't matter which Veracrypt boot loader i choose it shows
always that number, so i'm guessing this is some kind of offset to the system partition and now the number stored is the one for the Windows 10 system partition.

Does anyone knows where Veracrypt stores this number?

Does Veracrypt support multiboot of 2 Windows system encrypted partitions on the same hard disk?
