I created a partition[16GB] and then installed PCLinuxOS. The Harddrive is 80GB. everything worked well. I competed set up steps 4 my development environment, Just yesterday I created another partition[21GB] and Installed Windows 7 on it, but when I restated the computer after windows setup finished, the computer just booted windows, my Linux Boot Manager was never given a chance. So, I put my LinuxCD back in and run booted PCLiunxOS from CD. I realized that windows installation had created a small partition[About 1GB] for it boot settings. I moved the files from that partition and rebooted, The computer did not boot after that, it just wrote "Missing bootmgr". So I run my LiveCD again and then I tried to Setup boot system. And everything runs smooth but when I restart the computer and the new message I got was "Missing Operating System" and then I just delete that small partition which was created by windows but still no luck... please help, I don't want to install linux again coz its already installed and I don't wanna loose my development environment, it took me a lot of time and bandwith to put it together.
