I accidentally deleted the boot loader for Windows 8 (I think). Here is the situation: I just got a new computer with 2 HDD (sda, sdb). Now, all of the windows OS was installed on sdb (all except for about 210 MB on sda). I formatted sda and installed Kubuntu 12.04.2 (which only loads the terminal because it says it can't find a screen, but that's another story!)

Now, my Windows 8 data and NTFS partitions, etc. are still on sdb and untouched. Unfortunately, I cannot see an option to boot into Windows 8 in grub, so is there a way that I can go about using grub to point to the Windows 8 OS? The only other option I can think of is to buy a fresh copy of Windows 8 and install it fresh (no, I didn't create a backup USB because I'm an idiot ...)
