I had a copy of Windows installed on my fusion drive

I wanted to switch to Ubuntu completely, So I prepared a bootable USB Drive for Ubuntu 22.04 LTS, and installed it on my HDD.

Then later I faced many performance issues with my current installation, So i tried installing Ubuntu on my SSD with my bootable usb Drive.

Installation Finished with no errors, but when i boot up on my SSD,
Ubuntu starts on the HDD Drive. It just shows the SSD folder with Error sign on the swapfile and root folder.

Both the times while installing, I used erase disk and install and chose the respective disk.
Why both the boot options lands me to the Ubuntu OS installed in HDD?

/root/ and swapfile are owned by root, not accessible for the normal user.

Open a terminal and type ls -l / and you will see a lot of root root and drwx------ on some of them

...the latter is the chown flags saying d for dirs and rwx [ read, write, execute ] for user, group and others, with - for not allowed) - when "not allowed" for current user these show up with the red X in "files" (nautilus)

So: this is nothing "failed", fully normal.

So you have two Ubuntu installations on two devices, an HDD and an external SSD (correct me if I'm wrong)

to boot from the external SSD you have you go to boot options menu of your device and select the external device

there are really good tutorials on how to change boot options and each device has it's own way of entering BIOS/UEFI boot menu. you can take a look at this answer on how to change boot options on Ubuntu

Btw booting from an external SSD can be tricky sometimes, it may disconnect for a millisecond and your device is shutdown...
