Grub Just Redirects to Windows
 

This Might Be Confusing But Let Me Explain. I reinstalled Elementary OS because It had wireless adapter bug issue (fixed it). So After Installing EOS again I still see the GRUB as boot option from the previous Install, but when I select to boot to it, it just boots me to Windows. Is there any way I can add EOS to it as a secondary option

Edit 1: When I boot the the Grub it just opens Grub Config and if I boot back to Win10 and check msconfig boot option only windows shows up there.

Edit 2: So I fixed it. I used something Called Boot-Repair-Disk, Worked Like a Charm
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt update
sudo apt install boot-repair

If comfortable using the terminal, go here, download the script (click the green dropdown button) and run it. Post the entire RESULTS.txt it generates.
Can be run from a liveUSB. This will give us some configuration data to work with

Linux User Not Comfortable with Using Terminal? Sounds Iteresting

You'd be surprised - everybody converting over (from Win especially) wants everything gooey. Sometimes makes it damn hard to help them.

Wild guess: you just clicked through the installer, which recognized a previous eOS install and made some erroneous decisions.

Another option is boot-repair iso, https://sourceforge.net/p/boot-repair-cd/home/Home/ Post the the boot-info results, the boot-repair doesn't always fix correctly.

It never showed up to dual boot with windows just wipe the drive and partition

=> Windows 7/8/2012 is installed in the MBR of /dev/sda.

What do you mean by this? Do you have a grub boot menu, or just a grub> grub prompt, or the grub option in the bios boot menu?

That listing is about a third of what I expected - if that is all of it, you might need to use a decent liveCD - say systemrescue; or Mint/Fedora/Ubuntu ... almost anything current.
Having an fdisk that can't handle gpt is just unacceptable these days.

During Bios Boot Menu it has option to boot to Ubuntu (grub) but when i boot to it it just boots to Win10
