I have a weird problem that i think the windows 7 'activator/loader' might have caused. here's my HDD setup so far: Partition 1: Windows 7 Ultimate (main OS, normal use) Partition 2: Windows 7 'Dummy' (installed because it's only way to boot into Partition 1) The only way to boot into partition 1, is to set partition 2 as active, then select 'Windows 7 Ultimate' on the Windows Boot Manager. If i set partition 1 as active, then reboot, the computer goes through the usual BIOS startup stuff, then there's a black screen with a blinking cursor. It's like 'the tunnel is blocked, so i bulit a road AROUND the mountain'... I have run the Windows 7 Install disc many times, and have run MANY commands in the repair console, including: bootrec.exe (bunch of different options, including /fixmbr, /fixboot) BCDedit (even more options, /set, /enum, /export) Diskpart (setting each partition as active, to see if it will boot from partition 1 or not) I've also ran the 'Startup Repair' thing many times also. (I've learned what ALOT of these commands can do, but still, CANNOT BOOT FROM THAT FIRST PARTITION!) I've also copied all the BCD and Bootmanager etc. files from Partition 2 to Partition 1 and can't see any difference in the 2 C:\Boot\BCD and D:\Boot\BCD (and w/e else there is) I have also tried certian things with EasyBCD (even breaking the boot process on Partition 2, but fixing it pretty easily with bootrec.exe /rebuildBCD or something like that) I would like to erase the second partition and get some free space for my first one, but if I do that right now, i would not be able to boot into windows at all. Note: i DO NOT want to reinstall windows on first partition again, i like it how it is, and want to keep it that way. Edit: I just remembered, about a week ago, i reinstalled Windows 7 on Partition 1 (it was time) and still didn't change this problem, i'm guessing the windows installer saw a working boot order and didn't change anything.
