What steps did to take prior to running make modules-install????
The steps in order are;
<prep the kernel source if using a supplied source rpm file>
make mrproper
make oldconfig ;<or use a known good working kernel config file here>
make menuconfig [or xconfig or gconfig]
make
make modules_install
make install
Something to download / extract / review / have handy:

If this is your first attempt at [re]building a kernel just remember if at first you do not succeed try try again. When I fist attempted building a kernel (back in 1998) I failed at least 6-12 times, sorry I forget the exact number as I have slept at least once or twice since then
