Hello beloved friends from tonymacx86, I recently (two weeks ago) managed to install my hackintosh, everything is running fine (some minor glitches with OpenCL & OpenGL on EVGA 970).

But, before I install my macOS Sierra I had two HDD. One had Windows 10, and the another had Windows 7, I'm not sure if they were on LEGACY BIOS or UEFI BIOS.

So, I got rid of my Win10 installation by using Disk Utility and ERASING the HDD with Win10 completely, installed clover and made my UEFI installation on that particular HDD.

But, as you can imagine, I messed it. Because, now, I can't seem to boot on my windows 7 on the another HDD. Strangely, I can see the disk in my OSX, copy files to my Sierra HDD. (ready only). Screenshots attached.

I can't figure how to boot on my another HDD.
I tried going into my BIOS and changing the order to boot the HDD with the windows, cycling between LEGACY/UEFI, but without success.

My question: Can I boot on my Win7 HDD or I lost the installation?

Did you try and see if you could boot Windows 7 independently, after disconnecting the macOS Sierra hdd[by disconnecting either Power or SATA cable] or you were unable to get a choice to boot Windows 7 from Clover bootloader expected to display both the macOS Sierra and Windows 7?

If you have not already tried disconnecting the Sierra disk and booting into the BIOS Setup with just the Windows 7 disk , please try that. Then you should able to see UEFI :HDDBrandname-xxxx-xxxx of your Windows 7 HDD if it is initially installed in UEFI mode. If Windows 7 is in legacy and Sierra in UEFI modes, I don't think you can dual boot with Clover. More than likely your Windows 7 is in Legacy mode. Windows 7 installation DVD disc does not give us an easy option to choose between legacy and UEFI mode but automatically leads us to Legacy mode installation. If you have created a Windows 7 USB Flash drive in UEFI mode [using freeware like Rufus], you can install Windows in UEFI mode. Always install Windows first, before Mac or linux to avoid Windows corrupting the bootloaders of the other OSes if Windows is booted before the other OSes still connected and powered to the system.

So, I'll try this method. Unplug my HDD with the Sierra installation, try booting the HDD with the Win7 installation.
I'll report in a few moments.
