I have a computer that had Windows 8.1 preinstalled. I install Slackware64 14.1 off dvd media. It recognized that the computer was running EFI and installed elilo and slackware boots just fine. However, how do I boot back into Windows 8.1? What needs to be configured?

Here is more information on the matter. I have two hard disks /dev/sda and /dev/sdb.

I simply added a new hard disk /dev/sdb and just installed Slackware on this hard drive. Only thing the Slackware installer did was update /boot/efi to include the Slackware entry.

/dev/sda
