So I just installed Ubuntu 14 on a separate hard drive from Windows 7.

But when grub2 boots up, I only see options to boot ubuntu, windows 7 is nowhere in sight. I've had to manually boot the hard drive with windows 7 on it to get in.

here's my disc info:

/dev/sda1 HPFS/NTFS (Windows 7 drive)

/dev/sdb1 HPFS/NTFS (TB drive)

/dev/sdc1 EFI System FAT (Ubuntu drive, grub is installed on this one)

If I run sudo update-grub I get:

Generating grub configuration file ...

Found linux image: /boot/vmlinuz-3.13.0-24-generic

Found initrd image: /boot/initrd.img-3.13.0-24-generic

Adding boot menu entry for EFI firmware configuration

done

Running sudo parted -l shows:

 3      242GB   250GB  8471MB  linux-swap(v1)

Any ideas on how to get windows 7 to appear?

OK, that's strange. Could you also add the output of sudo parted -l please? A possible (bad) workaround is to edit the menu.cfg file manually. –  terdon May 22 at 16:15
    
Ok, added the output. –  user283611 May 22 at 16:21
    
What's the output of sudo os-prober –  Braiam May 22 at 16:31
    
Huh, nothing at all actually. –  user283611 May 22 at 16:32

Boot into Ubuntu and run this command:

sudo update-grub 

That will detect the available operating systems and generate the /boot/grub/grub.cfg file.

Have you really installed Ubuntu on a FAT32 drive? I'm very surpized that works and you can expect to have all sorts of issues with permissions down the line. If this is a new install I recommend you reinstall and chose a Linux filesystem like ext4.

Ran that command already Generating grub configuration file ... Found linux image: /boot/vmlinuz-3.13.0-24-generic Found initrd image: /boot/initrd.img-3.13.0-24-generic Adding boot menu entry for EFI firmware configuration.... no windows to be found. I think it is ex4, but there's like three partitions ubuntu created and one of them is fat32 –  user283611 May 22 at 16:07
    
@user283611 please edit your question and include the output of the command. Was the Windows drive plugged in when you ran it? –  terdon May 22 at 16:09
    
yes all the drives are mounted. I edited the question so you can see the output. –  user283611 May 22 at 16:13
