Can't install Windows

[specialistHUN]

Hey,
I've built a new PC for my grandma (for internet, some movies, light Windows Movie Maker editing) and after the building I proceeded to Windows install. Here I have to admit that I wanted to install a pirated Windows on her PC because she didn't have the money for a clean Windows. I already had a pirated Windows 8.1 burnt on a DVD but I wanted to try Windows 10, I was like: If it works, huzzah, if it doesn't then install the good old Win 8.1. So I downloaded a pirated Windows 10 Pro x64 and burnt it to a DVD. After this I put the DVD into the DVD ROM of the new rig and it immediately told me to press a button if I want to boot from the DVD. I did so (just like so many times before), I got into the installer and I did the usual things. I set the language and added the partitions. I used my old 500GB Seagate HDD that was 1st my primary drive with Win 8.1 on, the it got replaced by an SSD and I used it as secondary drive, finally I added a WD Blue 1TB and this drive went to a temporary retirement. So with everything done the installation has started and after a couple of minutes it finished and I got the message that the system will reboot to continue the install. But after the reboot it didn't continue with the usual personalization settings but reseted everything and threw me back to language selection. Well I tried it again, I checked and my partitions were the same but I couldn't install windows, I got the message that "Windows cannot be installed to this drive" no matter how I deleted or reformatted my drive I got this message. I exited and checked the BIOS, everything seemed good, but I pressed the Load Optimized Defaults again just to be sure and restarted the progress. I could repartition everything again and finished the install one more time but it was the same thing: back to language settings. After this I tried manually booting up from the DVD drive 1st and then after the restart from the HDD but it was all the same, no matter where I booted from after the install it threw me back to the beginning. If I dismounted my DVD I just got the message that I should mount a proper boot drive. At this point I thought that this is some Windows 10 related glitch so I just pulled my trustworthy pirated Win 8.1 CD out (that I used for Windows install at least 20 times including to that 500GB drive like a year ago) and started the same thing. No difference, it did the same thing with Win 8.1. At this point I was really confused and just picked some old 200GB SATA II drive but the results were the same. 

I really don't know what to do I assume I'm missing something from the BIOS but I think I've tried everything. First I didn't really set everything just loaded the optimized defaults and enabled XMP plus made sure that AHCI is enabled. I tried setting up the boot sequence differently, or by pressing F12 and doing it manually but no change. 
 

Any ideas what am I missing? I've build like a dozen PCs already and I never had issues with Windows installation. Please help!
