This has been asked many times in his thread and I have yet to find a solution. I used EasyBCD to look at my MBR and there is no mention of any Hazar loader anywhere. So I have no idea where I'd go to remove this.
Unhide protected OS files, and delete C:\grldr Optionally, do bootsect.exe /nt60 C: to restore the original bootcode, but that's if your obsessive about removing all traces of it.
despite the fact that I'm dualbooting with Vista (both installs are on seperate drives), after running Hazar's Loa*er, I automatically boot into Vista. I used to have the option to select the OS however it just goes straight to Vista. I even have the default OS set to W7, but for whatever reason, it just wants to go to Vista. Luckily I was just testing out Windows 7 and didn't have anything of importance installed.
In a post, i don't remember where, Hazar wrote simply "delete grldr file in the root dir" (for me C:\). It worked for me, at reboot the watermark appear for a lot of seconds, then disappear and the PC return in grace period. I successfully repeated the activation without problems. Sorry for my poor english, i'm Italian.
