I have a Lenovo T400 running Vista home basic. I just upgraded my hard drive, having used Acronis from a boot CD. Everything seems to have gone fine, and the new hard drive booted up without a problem.
The problem ocurred when I tried to go from the main Vista user menu into my own desktop. On the first bootup after the new hard drive, things took a long long time at this point. Then, a blank blue screen (not the blue screen of death, but more like a generic windows background) appeared with a mouse cursor, and a error box (for the program Rundll32.exe) which said "Windows cannot access the specified device, path or file. You may not have the necessary permission rights." (My account is, however, set as administrator). Immediately thereafter another box appeared saying "you must restart your computer for the changes to take effect".
Perhaps foolishly, I restarted. On bootup the same thing happens, but no error messages appear, and I just end up with a blank desktop. I can run task manager, and even log myself out.
I have a Vista recovery CD, and I ran the "repair boot up" option, but it didn't find anything. I also have my old hard drive attached to an enclosure, so I can access anything on there if that is necessary.
Any help would be greatly appreciated!
