Hello, I've recently installed Mac Os X Lion, then I installed boot camp and rEFIt and NTFS driver for mac. Now, whenever I boot on Mas OS X and I try to install something or change a setting, it asks for my admin password like it always did. The problem is that, after I enter my password, the dialog dissapears, but the installation doesn't move further. When I click next, the password prompt REAPPEARS and so on. I cannot create another use account because it also asks me for my password and it's the same issue. It's like my system is "locked" and I cannot edit any important file or setting. I've searched on google to no avail. Anyone has suggestions? THANKS!
