Why does the system persistently boot from the HDD and not from the SSD?

Question

BIOS

Hello.
The question is purely Nubian, but I just don’t even know in which direction to look for information on solving the situation.
The bottom line is this: there is a PC, there is an HDD and an SSD, and the Asus UEFI bios utility. All hardware connections are made by the store.
I, in turn, installed windows first on the SSD, then on the Ubuntu HDD - profit, two systems, both are displayed in UEFI - choose which one to load. Then the devil pulled and I chose Disable for the disk with ubuntu, that is, the HDD. Then I decided to put another Windows on the HDD, everything was set up, but in the end the ability to boot the system from the SSD disappeared, it is only possible to enter the SSD drive from the HDD system as a second drive. From that moment on, SSD ceased to be displayed in the Boot settings and I can boot, as I said only from the HDD. At the same time, UEFI sees my SSD, but only nominally - in the Advanced section - no manipulations with it are allowed :)
To be honest, I don’t quite understand what to do)
Except for one not very reasonable action, when I chose Disable for the HDD, I did nothing more than the usual settings. The whole UEFI crawled out like. Let me know if you have any thoughts on this

Answer 1

I don't quite understand what to do

Physically disconnect the HDD, boot from a CD / USB flash drive with the windows distribution and start system recovery.
