Yes, GPT is the default for F16 so it is easier just to go with it. I
have tried the nogpt option and F16 installs OK (as it does without
it). However it still can't boot:

[root at dom0 ~]#  sfdisk -d /dev/VM/f16 
# partition table of /dev/VM/f16
unit: sectors

/dev/VM/f161 : start=     2048, size=  1024000, Id=83, bootable
/dev/VM/f162 : start=  1026048, size= 40916992, Id=8e
/dev/VM/f163 : start=        0, size=        0, Id= 0
/dev/VM/f164 : start=        0, size=        0, Id= 0
[root at dom0 ~]# pygrub -i /dev/VM/f16 
Traceback (most recent call last):
  File "/usr/bin/pygrub", line 691, in ?
    chosencfg = run_grub(file, entry, fs)
  File "/usr/bin/pygrub", line 545, in run_grub
    g = Grub(file, fs)
  File "/usr/bin/pygrub", line 203, in __init__
    self.read_config(file, fs)
  File "/usr/bin/pygrub", line 402, in read_config
    if self.cf.filename is None:
AttributeError: Grub instance has no attribute 'cf'

The error is in the parsing of the grub2 config I believe.
