Still cant get it to work. Same Red message when trying to login on app store.
My hardware is:
Core i7 2600k 3.4GHz
Motherboard Gigabyte Z68X-UD3-B3
Tried every method, many times, re-installed SL 3 times from scratch, and nothing.
Audio does not work, and my ps-2 keyboard sometimes does not works as well at start.
I got desperate, then I installed a SL virtual machine on VMware on Win7 on another HDD, where I could login to app store. I downloaded Lion there, copy it to an USB FDD, drop it in the Applications folder on the actual Snow Leopard HDD.
Then I tried both the xMove+MultiBeast method, creating an installer partition, and the UniBeast method, trying to install Lion from an USB FDD. Both methods did not worked, and I couldnt install Lion either way.
When booting from the Installer partition, it keeps rebooting my machine...and when trying to boot from the USB FDD, it freezes on the white apple screen at start.
I am totally out of ideas, since everything I tried did not worked.
