Windows 10: Dual Boot: Win10 and Fedora 22

I am trying to do a dual boot.
I have Win10 installed and the ISO file for Fedora22 on a DVD, but I can't seem to get into the Bios so that the DVD can run the setup file.

I've already partitioned my hard drive and have reserved a separate petition for the Fedora22 installation.
I want to make sure Fedora goes into the partition I have selected and doesn't try to overwrite WIN10.

Any advise on how I can do all this.

Thanks

msinfo32.exe shows Secure Boot Type as Unsupported -- Restore UEFI Boot?

Short story: I have been trying to set up my Asus Z97 as a dual boot machine with Windows 10 and Fedora 22. Windows 10 had been installed on the machine on a 256GB SSD. I added a second 256GB SSD and installed Fedora 22 on it. When I started this adventure,
the UEFI BIOS showed the Windows 10 drive as "UEFI OS". Now it does not. Windows 10 seems to boot fine when the Windows drive is the only drive in the machine or if I select it as the boot drive in the BIOS. However, msinfo32.exe shows Secure Boot Type
as Unsupported.

I tried using the recovery USB drive I created before starting my dual booting adventure, but to no avail. Based on some posts I found related to Windows 7 and Windows 8.1, this is not uncommon. Those posts had various discussions about using bcdedit.exe
and other commands to restore the MBR. However, it was unclear if this restore UEFI (secure) booting.

bcdedit returns the following:

C:\Windows\System32>bcdedit

The boot configuration data store could not be opened.

Access is denied.

So, any suggestions on how to restore UEFI booting and get Secure Boot Type to show as enabled?

Thanks!

 

Grub 2 does not detect windows partition by osprober

Dear Don Cuthbert,

Thanks for your help.Since I was used to first dos partition to boot either windows or linux in dual boot on bios systems I thought UEFI just records the address to point to windows or linux sector for booting. Thought Microsoft system bootloader partiton contains
all files for booting and rest of files in windows 10 basic partition. As linux hanged on upgrade from Fedora 26 to Fedora 27 I wanted to delete UEFI which I thought is a UEFI linux loader as I am used to efibootmgr in Fedora and wondering why the osprobe
is not recognising windows.My basic thinking for GPT UEFI was wrong as I thought it just records the pointer to windows or linux.

But now you made the concept clear. Now I am sure I will be able to dual boot windows 10 and Fedora 27 with this help.

Really appreciate your help.

Honestly? The Fedora forums would be a better place to ask, as many more of their users will have experience with that.

Off the bat, If your computer is recent it will use UEFI instead of BIOS and the Linux Distro will need to be able to support it. Plus The Windows bootloader might have to be replaced with an alternative that will accept Linux. Also the bootloader might be locked down to only booting OS's that have the right digital signature.
