Hello! Vista Home Premium came on my Acer laptop, but I wiped and reinstalled from a downloaded ISO with a good hash to get it my way, and used ABR loader to activate it offline. Has been great since last Sept when I got it. Last week I finally installed the free Win7 upgrade in C:\, moving Vista to D:\ by restoring a backup image to that drive letter. I used a loader to activate W7. Prior to using the W7 loader, both OSs were fine. But once I installed the W7 loader, when I boot into Vista I get the ole "this is not a genuine copy of Vista" routine, though I can fully boot into the desktop and use the OS. Any advice on how to uninstall the ABR loader would be appreciated. Also, any insight you might have into how dual boot systems work in terms of the BIOS SLIC tables.. ? Can the BIOS hold two strings? Cause I'm wondering if after installing the W7 loader, Vista sees a SLIC 2.1 table, when it's looking for SLIC 2.0, and that's the problem... ?? Or for all I know the 2.1 SLIC is emulated. Is there a way to find this out?
