fantastic. thanks!

Just to clarify, am I correct in assuming that the second line "Skipping legacy bootloaders..." means its ignoring the BIOS?

Also, does this mean that my only clear option is to reinstall Windows in UEFI mode?

I appreciate your persistence in this.

sudo os-prober

doesn't display anything.

Also, that was in grub2.cfg. grub.cfg doesn't give any indication of the Windows partition.

Slight correction: the Windows entry I just posted is in grub2.cfg. There are comments directly above and below it read

"### BEGIN /etc/grub.d/40_custom ###
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above."

and "### END /etc/grub.d/40_custom ###"

menuentry "Windows" { set root=(hd1,1) chainloader +1 }

It may be worth mentioning that at one point, I tried making an entry in 40_custom.

I just booted into Windows by entering UEFI and selecting the hard disk that Windows is on. If you could please read the update I just posted.

Also, could you please elaborate on your last sentence? I'm something of a novice.

I have Fedora 21 partitioned across a SSD and a hard disk and I have Windows 7 on a separate hard disk. What I'm trying to accomplish is having Windows 7 as an option in the grub2 menu.

I've had the disk with Windows 7 mounted and I can view its contents like any other drive, and the "disks" program says that it is bootable. I've ran os-prober and grub2-mkconfig -o /boot/grub2/grub.cfg but it doesn't seem to turn anything up. Where am I going wrong?

Some information that may be of use:

**UPDATE:

I was able to boot into Windows using UEFI. After I restarted the computer from Windows, I noticed that a Windows 7 entry had appeared in grub but when selected, it gave me the following errors:

error: file /EFI/fedora/x86_64-efi/ntfs.mod not found
error: disk hd1,1 not found

Any ideas?
