Good night, people.
Yesterday I was messing around to install elementary OS Freya and dualbooting with Windows 8.1. Before installing elementary OS I had Ubuntu 14.04 and W8.1 side by side perfectly, but wanted to try something else. At this point I had tried to install elementary OS twice. Here's what I did:
The first time:
Created a bootable USB with Rufus, everything working OK, selected option to "Erase Ubuntu and install elementary". Installed flawlessly (I want to believe), and gave me the final message asking to restart in order to enjoy elementary. Got a black screen for more than 2 hours. Finally I shut laptop down.
The second time:
Did the same, but instead of installing over the previous installation, I decided to manually configure the partitions. Deleted all partitions exceptuating Windows and a ~350 MB partition (the only ones left by a fresh Windows 8.1 installation). From the remaining free space I assigned 100 GB to elementary OS logical partition, ext4, mount point /; and took 6 GB for swap area. The bootloader was placed at /dev/sda wich is the default. No error installation, then the final message asking to restart. I restarted and got the same black screen. Shut the computer down and started again. Selected elementary OS option form GRUB and got the black screen again.
A strange thing is that GRUB only appears until you select Windows Bootloader. After booting into Windows, GRUB won't show up again.
Also wanted to create a recovery drive for Windows in order to completely erase Linux and try again but gave me an error message.
I attach the partitions according to AOMEI and Disk Management and the Recovery Drive error.
What could have gone wrong or could I have done wrong? Is there another way to create a rovery drive? AOMEI has something to create a drive to boot Windows but I'm not sure if it could help.

Thanks in advance guys, I hope I was clear and detailed enough.
