Find a drive to do a clean install and then you can
Use Setup Assistant
Clone the system (and Lion Recovery) where you want
This article is for single drives and boot camp partition but same applies
Lion needs to find free space for the recovery partition so try shrinking the volume you intended to use.
Make a Lion DVD as mentioned on several sites or on a flash memory card.
You can install Lion wherever you like but it is always best to start off with a bare drive initialized with the OS.
And it cannot be part of an array.
Also, this way you have a clean Lion OS you can clone for backup and then use Setup Assistant to import your files, and ready to go - leave the OLD OS as backup incase Lion and your software/hardware has an issue - a month or if you need/want to dual boot or something. ie, you need Lion for your iPod etc and iOS but do your work on SL.
Thanks again for a rapid responce.
I finally got lion on one partition and my daily "SilverKeeper" backup on the other.
Since the only thing I had on the two partition Hard drive was the back up and since the backup would get put on tonight any way I changed the drive to no partitions. This gave me the ability to choose the GUID option, which I did and then I installed two partitions and successfuly istalled Lion on one of them. I even tied Lion into the iCloud successfuly.
But I am not out of the woods yet! I brought My brand new iPad to lunch and was informed that my iPad was synced to my Lion at home and I was on the cloud. That blew my mind, I was impressed.
I then read the Daily news with out problem, however, when I shut down my iPad, that was all she wrote. I can not get the iPad back on. The best I could do was see the revolving gear start and then freeze. It's on charge now and I can not even get rid of the frozen gear.
Not sure this all has anything to do with the recent installation on my main computer, but it's mighty suspicious.
Need some help!!
