Dual boot grub will not find Windows 10

Hi, I read the article which you provided in your post. When I look at the options in the partitioning setup dialog during the setup, it does not give me an option for UEFI for sdc2. The only option is Bios boot

did the op use a 32bit iso instead of a 64bit iso, that would cause the problems.

The options, as explained in the site I linked to above, are in the BIOS not the installer for Kali. If you don't see an option like that in the BIOS, I'm not sure what you could do. Since your windows is UEFI, I expect that is enabled. You might check to see Legacy/CSM is NOT enabled.

This thread has the first instance I can recall seeing with suggestions that it is even possible to have UEFI Windows multibooting with any Linux distro on the same disk.

It's certainly possible and really isn't that complicated once you have some familiarity with UEFI. I have 3 Linux systems on a laptop with windows 10, all of which boot without problem. I did have problems setting this up but that was pretty much due to my unfamiliarity with UEFI when I did it.

I majorly botched my proofreading before submitting. This is what it was supposed to read:

I have looked in my BIOS for something about secure boot. I read this is supposed to be disabled in order to install Linux. There is a button to open a UEFI shell but every time I click it it says to disable secure boot. I can figure out how to diasable secure boot on any of the tabs. The boot tab doesn't have it. The security tab is ony for setting a pw. I have ASUS UEFI BIOS Utility Ver 2.10.1208. Is there any way to do this at a DOS prompt? The version of Kali Linux I used is -amd64

I was able to finally figure out how to see the secure boot mode in my BIOS. First you have to disable something and then it magically appears. I went and deleted the PK Key under Key maangement. (I watched a video on this) I have redone the kali installation and grub is working now except when the menu comes up, it loads up sda2, (this is the EFI boot partion) but I'm presented with a black background with white text stating there is a missing file...I have to press enter a couple of times to get the windows bootloader started which then presents me with a blue screen and 2 buttons. The top button is to start windows 10 and the lower button says "CONTINUE DEBIAN INSTALL". Like the installing isn't complete yet....this is left over from the original installation.

Does someone have an idea how I can get this menu cleaned up so grub says Windows 10, and it goes directly into windows instead of putting me through all the screens?

Since I wrote this post, my system is not presenting a dual boot screen at all. I have to plug in the stick and go into the bios to boot into Kali Live. Bios does not even see my windows drive to show in the boot menu. It appears after I have run windows live however. What should I do?
