os-prober doesn't seem to find windows 7.
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?
are you able to boot into windows 7? how? Is it installed in EFI mode or not? doesn't seem so. IIRC, when in EFI mode, only EFI system partition (/dev/sda1) is searched for OSes, because it is unclear that grub in EFI mode is able to boot an OS in BIOS mode. But if Windows is installed in EFI mode and you can boot it normally (or using your system's EFI boot menu before grub starts), run os-prober and upload your system messages generated by os-prober (using journalctl).
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 will. But before that, please give me the menuentry created for Windows in your
/boot/grub2/grub.cfg(there is amenuentryline which includes your Windows grub entry title. Give me that section).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.
Is it complete? Please give me a few more lines. Maybe the complete grub.cfg is also useful.
Slight correction: the Windows entry I just posted is in grub2.cfg. There are comments directly above and below it read
and "### END /etc/grub.d/40_custom ###"
Also, that was in grub2.cfg. grub.cfg doesn't give any indication of the Windows partition.
Oops, this is your own custom entry. So, please run
os-proberand give us the result.sudo os-prober
doesn't display anything.
You said that you booted it by selecting the HDD, not among OSes in UEFI menu; so I guess it is not UEFI booted. However, please run
journalctl -l -f, and in another terminal runsudo os-prober, then paste journalctl output somewhere and give me the link.Here is the link the the output: http://pastebin.com/YgAN8xUU
I appreciate your persistence in this.
