I am new to this forum and hope you people can help me. I start my Mac and everything is fine until I enter my password to log in. It accepts my password and for a few seconds it appears as if it's loading but then it just jumps back to the log in screen. The only thing I can think of is that it has something to do with me using the program Parallels to install a copy of Windows XP. This issue happened as soon as I rebooted after installing Windows XP on Parallels. A very important detail is that I got a kernel panic as soon as I started Windows XP in Parallels for the first time. I should also note that I had Parallels with a copy of Windows 7 a long time all ready and never had any problems with it. I restarted my Lion in verbose mode and there are no messages in between the loading of the log in screens. When I shut down I do see some Parallels messages but nothing alarming. I decided to remove Parallels from my Lion using the installer's Terminal. Now I no longer get any messages in verbose mode about Parallels when I restart my Mac but the problem remains. I hope someone can help me. I am not even sure Parallels caused this but it seems likely as it happened right after the kernel panic it caused.
