MacBook Pro boots only safe mode post SSD install +Migration Assistant

Hi,

Yesterday, I replaced the hard drive and the optical drive of my Macbook Pro (Late 2011, 13 inch, i7 2.8, 8 GB RAM) for two SSDs (using a caddy for the second one) and fresh installed Mac OS High Sierra.

Everything ran successfully. However, after using Migration Assistant (from my desktop computer, which is a Hackintosh) to transfer ONLY Applications, well, apps worked well until I restarted my computer. The loading bar went up to 100% but didn’t end up the booting process. I tried to reset the SMC, the PRAM, and to boot in Safe Mode. Only safe mode could allow me to boot the system and make it to Finder.

After this, I restarted the computer and three consecutive beeps, followed by a 1 or 2 second delay, began. This happened only once, as after that I booted in safe mode again (deciding to delete my login items just in case too), and after restarting again, the computer got stuck once more in the loading screen with the bar at 100%.

Any help would be tremendously appreciated! Thank you in advance.
