Technical problem for which I haven't found a hint of an answer online:<p>I'm installing CentOS 7.0 x64 on a Thinkpad, my first Linux install. The install seems to go fine but on boot, right after the BIOS splash screen, in text mode, I see the following, then it stops (I'm going to use italics to be nice to people with small screens):<p><i>Failed to open \EFI\BOOT\grubx64.efi - Not Found<p>Failed to load image \EFI\BOOT\grubx64.efi: Not Found<p>start_image() returned Not Found</i><p>Secure boot is enabled, in case that's important. I've no idea why backslashes are used but I'm going to overlook that for now.<p>I booted to rescue mode and looked at the file system. <i>/mnt/sysimage/boot/efi/EFI/BOOT/</i> indeed lacks <i>grubx64.efi</i>; I did find <i>/mnt/sysimage/boot/efi/EFI/centos/grub64.efi</i> [0] (I'm assuming the paths in the error message are all relative to <i>/mnt/sysimage/boot/efi</i>, because that's the only place I see relevant files).<p>Do I just copy the <i>grubx64.efi</i> file to <i>../EFI/BOOT/</i>? Change the path in some config file to point at <i>../EFI/centos/</i>? Or am I on the completely wrong path?<p>[0] Sh-ucks. My notes say the filename is <i>../centos/grub64.efi</i>; the error message says <i>grubx64.efi</i> (i.e., with an <i>x</i> between <i>grub</i> and <i>64</i>). Hopefully it's a typo in my notes. I don't have the laptop with me to check.
