Hi all, I can't boot Windows XP anymore. I have two OSs on my system. They are both on the same disk in different partitions. I have XP and Windows 7. I first installed Windows Vista, then Windows 7. Since I don't like Vista, I will return to Windows XP. So I reïnstalled Windows XP on the Vista partition. Here's where my problems began.... The Windows 7 boot choice didn't exist in the boot.ini file so I had to create it manually. Also i moved some files for XP needed to boot into the XP Partition. The Windows 7 partition data shows up as a drive D: on my XP image. I recreated the Windows 7 bootmanager with the recovery dvd. But when it was searching for installed OSes, it doesn't recognize Windows XP. Then, when I boot into 7, the Windows XP partition showed up as drive D . Also, when I open Disk Management, it only shows my dvd-rom devices, i don't see any of my four partitions! If I reboot now, I get a bootmanager with Windows 7 and Windows XP, but if i select XP it just reboot the system, instead of starting XP. Windows 7 boots up and runs fine. Cheers! Forza.
