I recently installed Ubuntu onto my PC. When I went to install it, there was no option to install alongside Windows, so I partitioned space for it myself. Ubuntu booted up just fine, but when I went back to boot up Windows, it didn't show up in my Grub menu. I tried "sudo os-prober" but got nothing in return from the Terminal. I also tried updating Grub, but no cigar.
So my question is actually dual in purpose, because I want to learn about this kind of stuff:
1. How do I figure out what is still on all my disks, and
2. How do I recover Windows 7?
And I guess, finally, if worst comes to worst, I can do a clean reinstall of Windows from a buddy's system, correct?
