Windows 7 doesn´t continue installation after 1st reboot

Hello everyone!

This is my first post on this forum so I hope I do it correctly. First let me give you some background.

Last week I bought a computer with a Gigabyte GA-F2A68HM-DS2H motherboard with Windows 10 pre-installed. I wanted to downgrade to Windows 7 and since I don't have any CD/DVD drive, I´m using an external one to install it.

Everything worked fine but when I was installing it, it asked me for a driver for my CD/DVD drive. I read on the motherboard's manual that the driver was located in the motherboard disk but it didn't show any compatible driver.

Since that didn´t work, I read on the manual that before selecting the driver, I had to configure the Onboard SATA Controller changing the OnChip SATA Type to RAID (I don't know much about it but I just followed the instructions). So that's what I did. I also deleted and created a new RAID array using the RAID BIOS setup utility as the manual says. I restarted the installation proccess and when I was asked to select the driver, this time it was showing a compatible driver. But after selecting it, it said that it couldn´t find any new device or something like that (I can´t give you the exact error message because I´m trying to install a Spanish copy and I'm just trying to translate to you what it said).

So then I procceeded to look all over the internet for solutions and tried most of them until one of them worked. I ended up changing some things so I don´t know which one did the trick; changed Storage Boot Option Control on BIOS to LEGACY FIRST, changed OnChip SATA Type to RAID, enabled all PORT0-3 Hot Plug and downloaded most recent SATA driver from the official website. So after all that it finally proceeded to the installation.

Everything worked fine until the first reboot happened. Instead of continuing with the installation as normal it rebooted before showing the Windows logo completely. Then, while rebooting, instead of continuing with the boot, it shows this screen (that is not my screenshot, but it is exactly what it is showing). I´ve selected all options but they all do the same; attempt to boot but failing after 5-10 seconds and restarting. And the proccess repeats again and again.

I already tried some solutions that I´ve found online; to change the Boot order on BIOS, change the OnChip SATA Type back to IDE, re-install Windows like 5 times, unplug my external CD/DVD drive before it reboots for the first time and re-do the entire proccess. But nothing works, it always gets stuck and reboots at the same point.

I have to make clear that I´ve used my Windows 7 copy on other computers so I know it´s not a problem with my CD. And as I said, everything works fine until it reboots. I would really appreciate all the help you could provide me because I´m getting really desperate

Thanks and greetings from Mexico!
