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

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

So recently I decide to try out windows 8 which was the trial version that I downloaded from Microsoft. After finish installing, I thought all my files would be gone but it wasn't, I still have the files but it was not installed as if I have the files and data but I wasn't able to run it because its not installed into the system for some reason. So after having a bad time with Windows 8, I decide to switch back to window 7 by inserting the window 7 disk, delete all the partitions and make new ones and installing it but here comes the problems.
After I finish installing window 7, I ran into multiple annoying things that did not have before windows 8.
First problem:
There has been a blinking white dash line on the top left which is annoying and I don't know what cause it. Picture below:

This is like the same line as the ones you get when your system unable to detect an OS but my system is able to boot up normally.

Second problem:
When I go into the bios, I saw a new thing in the boot sequence. There is this new thing call "window boot manager" which also bugs me and I want to remove it so bad, not only it annoys me, I must boot from that, even thought I installed the OS on the hard drive, when I put my hard drive as first priority, the computer cannot detect an OS and unable to boot.
Picture below:

That was only one problem, now I got another one which I got two freaking "window boot manager" instead of one.

Third problem:
My computer starting window part is completely mess up, instead of having a Window 7 new look loading screen, I got an old loading screen that looks like its from window Xp.
Pictures below:

Top left was before, the bottle right is now.

Additional problems:
When I create an partition for installing OS, now I that every time I create an partition, the window automatically creates an extra 128 MB partition that said (MSR) microsoft reserved. It created two of those as I was trying to make 3 partition. I have 2 hard drive, one 1TB the other one is 3TB. Ps: All my drives are GPT.

I have been struggling to fix this problem since sep/23/14 and I have not been successful, I tried to re install the OS 5 times, reset the bios, and still unable to fix it.
I really hope for the community to help me with this because Its ruining my life, Im spending a large amount of time on this and Im not able to get a good result, this is me at home) A good solution Im looking for is to be able to reinstall my OS without having to run into the problems I have listed...

Where did you get the Windows 7 disc you used to reinstall with?

You can download a legal copy with SP1 integrated from here:

Windows 7 Direct Download Links

Make sure you get the same version you have, Home Premium, Pro or Ultimate and 32 or 64 bit. Note that Basic or Starter is not available.

I recommend using ImgBurn at 4X speed (or the slowest available) to create the DVD from the downloaded .iso file. Just be careful during the install not to accidentally install some of the bundled junk that comes with it. Always take The Custom Install option.

You can do this on any computer capable of burning a DVD.

YOU MUST HAVE A VALID KEY TO INSTALL THIS .ISO.
The one on the COA sticker on your computer will work.
If you are just using the Recovery Console you do not need a key.

You can also create a bootable USB Flash drive (4GB or larger) to install Windows 7 from.
  • Download and run Universal USB Installer Easy as 1 2 3
  • Select Windows 7 from the first drop down list, all the way to the bottom
  • Select the downloaded Windows 7 iso file
  • Select your USB flash drive
  • Click Create
Once you have the new disc/flash drive, do another clean install following these instructions:

Clean Install Windows 7

Please post back a screenshot of Disk Management - Post a Screen Capture Image. You likely have an EFI install if you have Windows Boot Manager actively in the boot order now. This can be confirmed by the presence of an EFI System partition.

The issues may be caused by stray boot code leftover from Win8 which can be cleared by running a few Startup Repairs from disk, or by reinstalling after wiping the boot code and partition table using Diskpart Clean Command.

Yes I do have an EFI installed, its the 100MB one, Im sure its left over from the Windows 8 install but Im not really sure how to remove it, and I have two hard drive, they are both GPT, I think the one I installed the OS on was MBR.

Where is the requested screenshot? Click on the blue link for how to post it from Win7 now.

Did you not pay any attention to where you were installing Win7?

All other HD's should always be unplugged during any install.

If you clean the drives everything will be wiped off.

If you want to try to fix what you have then post back the screenshot
