Unexpected VeraCrypt Bootloader

[antonio esposito]

Scenario:
Veracrypt 1.24 update 7 64bit;
-System disk (SSD) with a windows 7 partition and a data partition, fully encrypted;
-three (3) data disks, obviously non-booting, fully encrypted
Al of the above disks are connected thru the SATA lines.

everything is OK. For maximum security I extract the SSD and take it with me when I leave home.

problem: I get back home, turn on the PC forgetting to re-insert the SSD and... the VeraCrypt boot screen appears (!).
Where does it came from? I believe the only disk with the VC bootloader is the system disk... which is not connected. Maybe fully encrypting a disk installs the VC bootloader on it? Which would be the purpose?

To be precise, there are no other volumes (disk / USB drive / CD / else) connected to the PC.
Thanx for any idea,
Antonio

Hi again,

Investigating I got some additional info:

I tried to boot up the PC by connecting the 3 data disks one at a time: the UFO boot record is located on the second magnetic disk, which is the last I have added and therefore the last I encrypted.

So,

1. why Veracrypt has written its boot record on a data disk? (and only this one)
2. I am going to back up the MBR on this disk and then replace it with a standard MBR (using something like MiniTool Partition Free); is there anything wrong in this procedure?

Greetings
