Windows 7: Computer Boot is mess up after installing Windows 8 and switching back

Is there some reason you couldn't follow the simple directions in the link to post the screenshot the way we want it?

Problem is you converted DISK0 to Dynamic disk which is only meant to span a partition across multiple hard drives.

It would be best to start over and reinstall. You are currently installed in UEFI mode so would boot your WIn7 installation media as a EFI device in the boot menu, delete all partitions during the install using the Drive Options pictured in Steps 7/8 of Clean Install Windows 7, to create and format new partitions as desired. Back up your files first, and unplug the other HD's.

If you want to try to repair it you can use the non-destructive option to try to preserve what you have following Option One in Convert a Dynamic Disk to a Basic Disk. Any other method to convert it back to Basic will destroy all the data on it.

Be sure to back up your data first.

Another thing I suspect is that everytime when the pc restarts, the pc makes a loud and weird noise, it sounds like a train horn.

If you're sure you deleted all the partitions and had only unallocated space, then the EFI partition was created during install because you have an EFI install, which is fine and exactly what I suggested you do.

Does it boot and perform normally now? What is the exact problem?

Open the case to see if you can pinpoint where the loud noise is coming from.

An EFI install should have the Windows Boot Manager as first boot device. Why are you even concerned about this? If you need to boot another device like a disk, use the one-time BIOS Boot menu key.

I assume is running normally now, I can boot up and use it like usually without having to put "windows boot manager" as the 1th priority but im just bothered by the fact that the "windows boot manager" is still there... because before I installed windows 8, the "windows boot manager" is not there so im just really looking for a solution to remove it from the boot sequence. Is there anyway to make the "Windows boot manager" go away or not perform a EFI install?

Windows Boot Manager is how an EFI install boots itself. You'd have to Bypass UEFI to Install WIn7
to avoid it which requires adjusting your BIOS to enable Legacy or CSM, booting the installer as a non-UEFI device, deleting all partitions during install to clear the GPT formatting.
