UEFI boot hangs (almost) all the time

[mikeromberg at comcast.net]

  I'm attempting to install Fedora 19 on a Dell inspiron 15z which
came with windows 8.  I would like to be able to dual boot the laptop
between the two.  It is not going real smoothly.

  Things I am assuming:

  - Windows 8 is installed to boot in UEFI mode. Changing this
    probably involves more pain and suffering than would be considered
    decent in any modern civilization.  So, Linux must boot in UEFI
    mode as well.

  Things I know:

  - The live-CD boots fine in "legacy" mode.

  - Windows 8 does not care if "secure boot" is enabled.  So, I
    disabled it.

  - The live-CD almost never boots in UEFI mode.  It hangs after
    displaying either "Secure boot disabled" or "verified by vendor
    certificate".  From what I read this means the shim ran.  But
    nothing at all happens past this point.

  - The live-CD did boot exactly one time!  I then used it to install
    fedora to the hard drive.  It has never booted again.

  - Grub appears to be installed on the EFI partition and does display
    a menu when the laptop boots.

  - Grub *CAN* boot windows 8 in UEFI mode.

  - The fedora installation on the hard disk hangs after the same
    message as the live-CD

  - I can mount the fedora install with the netinst-CD image (booted
    in legacy mode).  And used it to run yum update to upgrade grub
    and the kernel.  But... Still the same hang at boot for fedora.

  It seems to me that something is going wrong when grub tries to hand
things over to the kernel.  Does anyone have any suggestions about how
I might make grub and the kernel a bit more chatty about what is going
on?  Or does anyone have anything else I might try?  I could wipe the
disk and switch to legacy BIOS boot.  But I really don't wanna go this
route.

Thanks,

Mike
