slow start after removing a hard disk

Question

I use Ubuntu 18.04.03, and the start was always very fast. But since I removed one of my hard disks, the procces of start takes a long time. I think somewhere there is a reference to de missing disk and the system is trying to find it until a timeout period. Where should I look for that reference to the removed disk? Or is something else? thanks

I understand that at instalation time, the disks and partitions were named different than now

In terminal...

sudo -H gedit /etc/fstab # edit fstab file

change:

UUID=af9cbf4b-7a29-422e-b24a-e620301b8369 none swap sw 0 0

to:

#UUID=af9cbf4b-7a29-422e-b24a-e620301b8369 none swap sw 0 0

save the file and quit gedit.
