UEFI Problems

Looks like systems with older UEFI systems need an older BOOTX64.EFI file.

I found this out when trying to boot my system on an older DELL


I mounted an older CentOS (CentOS-7-x86_64-Everything-1804.iso) and it worked.

Article also mentions a patch available, so I downloaded the rpm

wget http://mirror.centos.org/centos/7/updates/x86_64/Packages/shim-x64-15-2.el7.centos.x86_64.rpm

Created a directory and extracted the contents

mkdir NEWEFI
rpm2cpio ../shim-x64-15-2.el7.centos.x86_64.rpm | cpio -idmv

Still didn’t work.

Will continue testing.
