Hello, I made a mess from the boot and I clearly need some help. I installed server 2008 over a previous vista installation. When I got to <where to install> part I formatted c: to get rid of vista and installed over. I forgot that vista doesn't go away that easy, so after I finished the installation and restarted the comp I found that I have to choose between "Previous Windows Installation" and Windows Server 2008. After I searched the web to find a way to remove the "Previous Windows Installation" I found a program (can't remember right now the name but if need I can search for it again) that said that can configure the boot menu and stuff like that. Run, find "Previous Windows Installation" delete entry, restart. Disk boot failure.please insert system disk and press enter. My installation was clean, I didn't have anything to recuperate from c: so I thought that what created the problem can solve it. Reinstall WServer2008 and it will fix it. Well, not really. It works but only if I have the installation dvd in the drive. Otherwise I get Disk boot failure, insert system disk and press enter. Please help. Thank you.
