Q4os system will not boot

Hi all,
I am starting a new issue on this, though it is mentioned in another post.
My q4os system is dual booted with W10, on a 120 GB ssd, and booting both has worked fine. But after problems with insufficient memory
I decided to add another ssd, this time 250 GB. My computer recognonized both disks, but would not boot. I then went back to 120 GB only,   
and that's when my real problem showes up. Booting let me choose between w10 and q4os, so I pick q4os. Then the screen appears fully
normal, as it did before, many lines of code, mouse printer showing up on an empty screen. Then - nothing.  The actual program never shows. Also, when I shut down the computer with the power button, being the only alternative it behaves normally, multiple lines of code, and shutdown. Sounds like the program actually starts, but why not visible ?
I did some attempts to install Linux on the new disk, so may have messed up bios, but why should that look like this.....
I really need advice on this, being totally lost !

Re: Q4os system will not boot

Does your Windows 10 work at least?

It's possible that attempting to install Linux on the new disk corrupted the Q4OS partition or its file system.

How to check?

Use recovery mode again.

From the command line, run fsck to check the file system:

First, you need to know the partition where your Q4OS is located. You can use sudo fdisk -l or lsblk.

For example, if your partition is /dev/sda2, run: sudo fsck -f /dev/sda2. The -f option forces the check even if the file system appears clean.

I think you misunderstood, I have no functioning linux system. The plan was to install a clean q4os on a new disk,
as a result the system I had dualbooted stopped working.

Re: Q4os system will not boot

By live media you mean an iso file on usb ?  But what I really want is getting my
existing system up and running.
Am I missing something here ?

Yes. And you need your usb to be bootable. HowTo explained here.

Yes. You complained not having a working system to run the commands advised by Josek (in the hope to find where the problem is and to try to restore your system).
