Mac OS X v10.7 Lion always boot into safe boot after upgrade?

I have recently upgraded my OS from snow leopard to lion and the upgrade process was smooth and no problems encountered.

I am also running boot camp with windows XP installed in the same iMac.

After the upgrade, my iMac almost always boot into safe mode whenever I switch it on and I need to restart it again and it will then return to its normal mode.

I wonder anyone encounter the same problem and if so, please give me a hand to solve it.

Thank you very much!

iMac, iPhone, Power Book G4 & MacBook Pro, Mac OS X (10.6.1)

The problem seems to occour if keyboard and iMac are switched on with only a few seconds between.


I just tried it again, three times in a row i put on my iMac and my keybord :


- iMac / 2sec / keyboard

- keyboard / 2sec / iMac

- iMac / 0sec / keyboard


All three times i run into safe mode



The fourth time i did it this way :


- keyboard / 15sec / iMac


=> normal Boot

by the way the keyboard LED was flashing while boot, this did'nt happen the first three time


So the solution is : Apple, fix it !


Meanwhile :


a) do not swicht off the iMac

b) do not swicht off the keyboard

c) switch on keyboard after boot

d) switch on keybord 15sec before iMac


... I will choose c)

The exact same happens to me:

Every single time I turn on my iMac and in the next 5 seconds I turn on the magic mouse and/or keyboard I ALWAYS get into safe mode.


SOLUTION: turn on imac then, when I see the desktop, I turn on my keboard and MM.


HOPE APPLE FIX THIS!!!


===========

I think i got it :


The progressbar while booting ( booting in safe-mode ) came from the wireless keybord and is reproduceable.

At evening I shut down my iMac an put off my mouse and keyboard. To startup I put on the iMac and immediatly after I switch on keyboard and mouse. In tihs case the keyboards sends some event wich leads to safe-mode.


Know I wait until I switch on the keyboard. In my opinion this is a bug, i can live this way but i hope it will be fixed.


I will know take a look at it while not switching off the keybord, power consumption should be acceptable
