I am running Win7 Ultimate 64. I ran PAT 2.0. It said one of my drives needed alignment. I selected that drive and it said that Windows would need to reboot. Windows rebooted and PAT ran a DOS screen which started with about 7 blue dashes. Then another screen came up, displayed several things like checking file integrity, etc. Then it rebooted and came right back to the same DOS screen. This reboot process continued about 6 times til I got frustrated and escaped out of the problem. Tried to boot into Windows and instead got this DOS screen over and over. Finally escaped out, shut down the computer, unplugged the power cord, hit the power button, rebooted, and I got the windows dos screen about windows not starting correctly. I selected "start windows normally" and back came the PAT dos screen again. ARG! Finally ran system restore, got rid of PAT, but now every time I boot Windows, after the BIOS but before Windows starts, I get the blue dashes. It also takes longer to boot up. Is there a remnant of this PAT left behind somehow and how do I get rid of it!!! It's been fairly frustrating.
