Why won't Linux Lite start without a second HDD?

Question

linux

When I installed Linux, I already had an old HDD (sdb) instead of a drive, but I didn’t use it during the installation, but without a disk it doesn’t start and asks me to press Control + D, and this is a cycle. Above, the commands "systemctl reboot", "exit" are written, where I did not find where to enter, I pressed everything that is possible and combinations too. Could this be due to the "Connect at system startup" checkbox being checked in the gnome-disks utility?

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 119,2G  0 disk 
├─sda1   8:1    0  80,1G  0 part /
└─sda2   8:2    0  39,1G  0 part 
sdb      8:16   0 465,8G  0 disk 
└─sdb1   8:17   0 465,8G  0 part /media/usr/681D380C7E6DC0D1

Answer 1

Yes, because of this.
Remove mentions of this disk:
sudo nano /etc/fstab
Then start up without it.
The system tries to mount it at startup.
