        Use win7 and fedora dual system if you directly format the partition where fedora is located, because the grub written mbr can not find the corresponding configuration file. So can not start win7. At this time need to repair mbr, the specific method is as follows: Insert win7 system installation disk, set to drive CD-ROM After selecting the language option, go to the next step, select [System Repair] in the lower left corner instead of continuing to install. After automatically searching for the installed system, go to the next step. Do not point to Windows automatic repair, but enter [command prompt mode] first enter the command bootrec /fixmbr Enter, then enter the command bootrec /fixboot and then restart the system to repair the win7 boot mode. This will restart win7, but it is best not to directly format the disk where fedora is located.
