Solved BSOD at startup windows 7 error 0x0000007B

[WIN7NL]

Hello i have an laptop, an Asus N56VZ-S4035V

specs:
CPU: i7-3610QM 2.3 GHz (up to 3.3 GHz with something called "Turbo-boost")
RAM: 8 GB DDR3 1333MHz
HDD: 750 GB 7200rpm (BUT I CHANGED IT TO A SAMSUNG 840 EVO 250GB SSD WHEN MY HDD BROKE)
GPU: NVIDIA GeForce GT 650M 2GB
OS: W7 64 bit

So a few days ago i did the free update to WIN10 but I didn't like it so i downgraded it back to WIN7 and after the downgrade (that seemed to go just fine) when my laptop started up it gets stuck at the : Starting windows screen and then i get the BSOD and then i get at the black screen with white letters, Windows 7 startuprepair. Well, when i clicked on the 1st option to automaticly repair it, it said that it couldnt be automaticly repaired. and when I click on start windows normally, i get the exact same things. (freeze,BSOD,startuprepair).
So i made a win7 bootable dvd with the windows usb/dvd tool and an ISO that i know that works cause I used it before and on another laptop that does work I do get the win7 install screen.
So when i went in the BIOS and changed the startup order or something like that, that it would boot from DVD, I get the exact some order of things that i said earlier! Nothing changes! I also tried to change the BIOS setting from AHCI TO IDE and back and some other stuff. Also when i reset the BIOS and just clicked esc and clicked to boot from dvd I also got the same order of things! (freeze, BSOD etc.) So in short, I cant get in windows !
Please can somebody help me? I would be glad to post som pics or so if someone tells me how!

A 0x7B indicates an inaccessible boot device, it's strange that you're getting the same error when trying to boot from a DVD though.

ehm i have an ssd not an hdd and it isn't from seagate, its a samsung 840 evo 250GB. Can i still use the programm? Sorry if i said anything dumb haha! And when I just disabled the option to boot from HDD, I do get the screen that says< Reboot and select proper boot device or insert boot media in selcted boot device and press a key < I click and then i get the message again and again under eachother and so forth grr! Gonna try a USB in a few minutes.
This is the ISO btw http://kat.cr/windows-7-all-in-one-pre-activated-excellent-t7661549.html

Ah no sorry, I completely skipped the SSD part. In that case can you switch the SATA cable to a different SATA port on the motherboard and try booting again.
