Empty disk added every reboot on 7.11 x86

I have a PC with RouterOS 7.11 installed. When routeros is booted, an empty disk is added and the configuration looks like:

/disk
set slot1 slot=slot1 type=hardware
set slot1 slot=slot2 type=hardware
set slot1 slot=slot3 type=hardware
set slot1 slot=slot4 type=hardware

They can be removed but appears on next boot.
RouterOS on my PC is installed with UEFI so I guess Routeros detects the efi partition and adds it to disk list incorrectly.
Could anyone figure out the reason and tell how to fix this bug?

Finally I found out it’s the SD card reader. If there is no card, RouterOS will add the SD card controller into

/disk

. So disable the SD card reader in BIOS will fix this.

Great work, and thank you! :smiley: Please consider marking topic “SOLVED” by your solution which helps anyone arriving later.
