Windows Linux dual system remove Linux repair directly
With Win7 and Fedora dual systems, if the partition where Fedora is located is formatted directly, the corresponding configuration file cannot be found due to the grub-written MBR. So you can't start Win7.
The MBR needs to be repaired, as follows:
Insert win7 system installation disk, set to drive boot
After you select the language option, go to the next step and select system repair in the lower-left corner instead of continuing the installation.
After you have automatically searched the installed system, go to the next step.
Don't point to Windows auto Fix, but go to "command Prompt mode"
First enter the command BOOTREC/FIXMBR enter, and then type the command bootrec/fixboot
Then reboot the system to fix the win7 boot mode.
This allows the Win7 to be restarted, but it is best not to format the Fedora disk directly
