doubt it. i'm actually testing every release on a windows 7 with vmware
doing a install from scratch, then building amd64 on the newly installed
system and reboot into 64 bit kernel as a regression test.

however, in your case i'd suggest a more systematic approach and actually
check what the status of the mbr / partition table is. you can do that
from the system booted off the iso. just run disk/fdisk /dev/sdC0/data
and see if the plan9 partition has a "*" there.

the mbr should look like this:

cpu% dd -if /dev/sdC0/data -count 1 | xd -x1
1+0 records in
1+0 records out

once we know the status of that, we can worry about *why* it is this way
in your case.

maybe your download got corrupted? (we did have this case in the past)
just to make sure, the latest 9front-5368.b4963e7e3204.iso.bz2 file
has sha2-512 sum of:
