Windows 10 has killed grub2, how can I recover the grub to access to Fedora again using a Fedora Live USB?, I'm sure that i installed fedora in uefi mode, I had used for some time Fedora in dual boot with Windows, but after some time, the grub2 didn't appear, Windows 10 started directly.
PD: I'm using a laptop, Acer Aspire E-15
