Problem recreating grub2 menu in SL7 dual boot with Win10

Hi
In fear and trepidation I ran a BIOS update on my Acer Aspire A515-51G from the Win10 part of my dual boot (only Win10 can update the BIOS). On reboot, all I get is Win10 (Surprise! Surprise!).
So I booted into an SL7.4 USB recovery mode with chroot /mnt/sysimage and tried grub2-install /dev/sda only to be told /usr/lib/grub/x86_64-efi/modinfo.sh doesn't exist.
It appears that I need to do yum install grub2-efi-modules (why wasn't this done before? I ask).
Anyway, how do I install this while in rescue mode, which doesn't seem to have network access? Or is there a network enabling option for rescue mode (like there was in SystemRescueCD)?
Am I being dense in my old age?

Cheers
