Apple HDD internal hard drive not showing up as startup disk option

Just like the title says. I recently bought a used 2015 imac. The SSD shows as an option to use as a startup disk but the HDD does not. The HDD is formatted and shows up in disk utility with 1TB of free space, but it is unusable because of this issue. Can this be fixed?

Cannot see new Startup Disk after careful installation of new version of OSX Hi all. I run OSX 10.14 on my MacBook Pro and wanted to upgrade to Monterey but only on an external SSD so that my old Photoshop CS6 applications could still be used as I could flip between Monterey and Mojave operating systems. I carefully downloaded and installed Monterey on my 1TB SSD and successfully rebooted into that version and installed some new versions of my Apps, namely Final Cut Pro X. I then switched back to OSX Mojave by selecting 10.14 as one of the 2 options in 'Select the system to start the Computer'. I was really disappointed to see that the OSX Monterey system was not displayed in the Startup Disk panel under my Mojave system and I could see no way to reboot under the new up to date version of OSX!. I tried a reboot and reset the Non volatile memory to no effect. Any thoughts or help would be most gratefully received. Regardf Richard

How to remove Startup Disk from About This Mac? I've been wondering how this happens because when I usually open the About This Mac feature to check the information, it doesn't display the main drive/startup disk (Macintosh HD) most times although when I use disk utility to view it and make a change then it appears on the information. I am very confused about this because it goes back and forth between displaying the startup disk on About This Mac to not displaying it at all, which makes me think something is triggering it, like a switch. I was wondering if there is any reason how this happens because I haven't really seen anyone talk about this from my browsing, and also if there was an option to remove it and be able to add it back in again, because even I prefer not seeing the startup disk information on the features although I don't mind seeing it there as well, and I would like to have an answer since this got me very curious, many thanks.
