Using the Fedora CD/DVD or USB follow these instructions. These instructions are for a uefi machine.

Here's the Fedora Grub WiKi-

Hope those instructions help.

After a new version, always start by looking at the "common bugs" for the (new) release.
Is this UEFI, or an old BIOS system that has upgraded to Win10 ?.
Is it actually the grub menu ?. If so, grub is probably ok, and shouldn't need re-installing - but it generally can't harm.

I believe it’s a bios system. It’s an old pc from 2012
Win 10 was existent from the beginning it’s a fedora upgrade

Nope - if it's a 2012 PC, it didn't come with Win10.
As I said, have a look at Common_F30_bugs.

Chances are it was Windows 8--

On August 1, 2012, Windows 8 (build 9200) was released to manufacturing with the build number 6.2.9200.16384 . Microsoft planned to hold a launch event on October 25, 2012 and release Windows 8 for general availability on the next day.

Read under the Heading: "GRUB boot menu is not populated after an upgrade" that syg00 posted for you.
