Hello & Welcome to JustAnswer.
Thank you for your question. I will do my best to assist you.
May i connect with you remotely to troubleshoot the issue directly? Thanks
I sent request for remote service. Please accept it then follow steps here to connect with me.
No problem. We will need to see what is causing the disk to be utililzed, and delete the unwanted programs. Please download and run Windirstar and it will show you the stats.
Once it finishes, it will show you the stats. You can then locate those unwanted files and remove them.
No, the issue is quiet simple. And windirstat will tell you what is consuming the space. You need to remove those unwanted programs, files etc.. to free up space.
Is Fastboot on? I think i can only troubleshoot this if i am connected remotely. Else, i will have to opt out and open the question to other experts. Let me know.
Yes, i don't think it has anything to do with Windows. If it was loaded incorrectly, it would not start at all or give you errors
You can disconnect all other drives, and then do a fresh install on the SSD. Once it has been installed, you can then add the HDD as the secondary. You cannot install Windows on SSD without removing other drives, C:\ has to be the Windows. (This is what i normally do). Second option is that you do a clean install, and choose the disk where you want windows to be installed, but if C:\ is not the main drive, it can cause issues in future. When you do a clean install, you will be given the option to choose the drive, but i will not recommend it. https://s32.postimg.org/zb7ipf51x/2016_07_31_151655.png
Can you check if Fastboot is on?
