I installed Fedora on my system preinstalled with windows 7. Now during booting Windows 7 is not appearing. It is only showing Fedora. But it should show both the os and allow us to choose. Help me to resolve this. Thanks in advance.
When you installed Fedora, did you follow any special instructions about how to install with Windows 7? If you are using GRUB right now to boot, you will have to add the Windows 7 boot menu, but I do not remember how exactly. You might check some other sites, a Wiki from a Linux site.
EasyBCD (v 2 or above) is a good way to set up dual boots, but I think it does not run in Linux, so you would have to get back into Windows 7. Did you install both OSes on the same hard drive?
Do you have a Windows 7 Repair CD or an Install DVD?
If you decide you want to use the Windows 7 boot, we might get into a command for restoring the Windows 7 boot senario by using Bootsect, which is described here, or you may end up doing a Startup Repair. So, do you want to use the Linux GRUB, or Windows 7 to boot?
