I failed also to drag the installesd.dmg on the flash memory, I ended
up creating a dvd and on imac mc508 from mid last year it installed
properly using the clean install method, so as well on mac mini
standard configuration 2.4ghz and as of yet 2gb ram which will be
upgraded to 8 like the imac. The weirdest and most difficult install
was on the macbook 13inch white from Februray 2009 when it was
purchased, used same dvd to make a clean install and it kept hanging on
me after 24percent and kept saying downloading additional components
and when reaching 100percent a dialog box popped up saying it failed to
download. I ended up putting snow leopard again then upgraded it and
finally used the contents of the dmg file to install and yes it
downloaded components and it is working fine. If somebody can solve
this mistery of dragging the dmg file to the usb memory I would be more
than happy. Wonder what happens if we format the flash drive in disk
utility with mac os x journalled choosing the guid layout and at the
end copy the contents of the dvd or install lion.app directly in the
root of the flash drive keeping the structure of course but we use
finder instead, I didn't try it and have no vision to tell about any
logo of any sort just wanting to do it. Finally how would one boot
from the flash memory and the most important thing how to know when to
press command f5 as it doesn't make spinning sound that stops like the
dvd, any clues?
Frustrated because I couldn't make a bootable lion flash drive.
Original message:
Hey everyone, ok, here is my experience so far. One of my other macs is
doing the install now. Purchased the app and downloaded it. Used disk
utility to make a bootable DVD, also attempted to make a bootable flash
drive, but disk utility seems to require you to drag the disk image to
the destination, tried that but couldn't seem to get that to work. So I
used super duper to clone the image to my flash drive, actually it's an
8 GB micro SD card and a card reader, but should be the same. Attempted
to boot the mac using the flash drive first, that didn't seem to work,
the apple logo displayed for a while, then the screen stayed blank,
waited for about 15 minutes, then I decided to try the DVD I made.
Having better luck with that, mac booted, started voiceover and used
disk utility to erase my hard drive, since I want to do a clean
install. Now comes the interesting part, it wants you to enter your
apple ID and password, I guess to verify that you have purchased 10.7.
There are actually 2 windows open here, one is the installer, and there
is another window behind that where you need to enter your user name
and password. I know a few users have had problems with this, to get
around it, press control option function F2 twice. When booted from the
DVD, the function keys are configured to do hardware functions. You
need to do this key stroke twice, the first time reads the window
title, the second time will open the window chooser menu where you can
switch to the sign in window. After entering the user name and
password, it's downloading components, I figured it would just use what
was already on the DVD, it's probably downloading the same thing, but
there doesn't seem to be a way around that. Also, the customize option
was disabled, so hopefully it will not install all of the multilanguage
support, since I don't really need that or all the print drivers. Not
sure why the flash drive method did not work, but so far the DVD is working.
