I'm new to these forums, I registered to see if you guys could help me out with this issue.
I recently bought a 120 GB SSD to upgrade from my old 640 GB HDD, since I didn't want to install Windows all again I was planning on just migrating everything to the new SSD, ok what I did was that I backed up all the data to an external hard drive, then I started deleting some of the music, videos, photos from my HDD to slim it down and make it fit into my SSD, I was able to bring it down to 77.9 GB (SSD has a free space of 111 GB), so then I migrated everything to the SSD using the software that came with it.
I restarted my PC and booted from the SSD and then an error on a black screen showed up, saying something among the lines of "Windows failed to start. A recent hardware or software change might have caused the issue..."
Thinking that it was something wrong with the connection I tried with different SATA cables and even different ports(even connected the SSD to the port were the HDD was before) and the error kept showing up. I made the SSD the primary source of booting...nothing.
Then I used another program called EaseUs Todo Backup and tried cloning the disk again, and nothing happened, still the same error...so I gave up, I downloaded Windows 8 again (I currently have Windows 8.1 but since the version I bought was 8 it wouldn't let me download the most recent one), saved it to a USB drive as an ISO, and I booted from the USB, I did the "Automatic Repair" and it kinda fixed the problem, now the error doesn't show up anymore but I believe it created a dual boot since it gives two different options when I boot, one that says Windows 8.1 and the other one doesn't say anything.
Thinking that everything was fine now I went to My PC to format the HDD and I found that I was still using my HDD and not the SSD, it shows that Windows 8 is still installed on my HDD, I tried formatting the SSD again and doing all the steps one more time....nothing.
So this time I booted again from the USB and tried to do a fresh install of Windows 8 on the SSD, when I get to the screen where it says to select the partition I select the SSD and it comes up another error saying that there wasn't enough free space on the selected volume.
Here is a picture of my Disk Management, I don't know why but it created another partition "J" that has 100 MB which is filled to almost it's full capacity, maybe that's the reason why it doesn't let me install Windows, I tried formatting that partition but it doesn't allow me either.
