My son recently built his own computer and still needs Windows 10 for some games so when get got a new 2TB HD he installed Windows.

This weekend I walked him through installing Fedora. We resized the NTFS partition and grabbed about 500GB for Fedora. The installation went smoothly.

Upon reboot there was no GRUB menu. I know it's supposed to be hidden by default but not if there are multiple OS's installed.

First nit... I wanted to turn off the hidden menu. I knew from a previous list email and BZ that you shouldn't edit grubenv directly so I tried to do it what I thought was the RIGHT way...

When I tried the logical way

# grub2-editenv set menu_auto_hide=0 

I got an error. I thought it was odd but after looking at --help the command goes at the end so I did:

# grub2-editenv menu_auto_hide=0 set
(no error)
# grub2-editenv create

Now the grubenv only contains hashes. All the options are gone. Looking here:

Apparently if you don't want to specify the filename you need to use "-", so:

# grub2-editenv - set menu_auto_hide=0 

Next the bigger problem:

I tried running grub2-mkconfig into a temporary file and OS prober is not finding the Windows installation.

Going to check if both are booting UEFI or not... Could be the problem.

Thanks,
Richard
