I installed Windows 7 beta on a 2nd HDD on my Windows XP Home computer. The install went well and I had no trouble booting into Windows 7, accessing the web, installing a driver for my nVidia e-Ge-Force FX5200 video card and installing Norton 360 version 3 beta. When I rebooted and selected Windows XP I got the following error: "File:\ntldr Status 0x000000f Info: The selected entry could not be loaded because the application is missing or corrupt." I rebooted and ran the Recovery Console from the Windows XP CD and ran Fixmbr C: and Fixboot C:. When I rebooted, I did not get the dual bootup option but went straight to Windows XP. Windows XP is fine. However, I cannot boot to Windows 7. What options do I have to fix this problem. I do not mind reinstalling Windows 7. However, if I do so, how can I avoid this problem?Re-install it and LEAVE Norton off this time...wow. not only was it Norton, but it was Beta as well. Even I can't seem to think of a metaphor extreme enough to FIT this situation. The only THING WORSE then an AV that does absolutely nothing is an untested AV that does absolutely nothing.
