I installed Ubuntu 13.10 alongside Windows 8 a couple days ago.
Today I tried to set up
l2tp following some complicated tutorial on the web, messed up some configuration files, and since it was a fresh installation, I have decided to simply reinstall the OS.
After booting from USB stick, I've chosen Install Ubuntu from the menu. On the next screen, I selected Remove Ubuntu and reinstall. Underneath the caption, there was a warning saying that I will loose my Ubuntu files, profile music and stuff.
Nothing at all was said about my Windows partition, only about Ubuntu. I had Ubuntu installed to a separate 50GB partition, so I continued.
After Ubuntu was installed, I've noticed that Windows is gone from the boot loader. I also couldn't access Windows partitions from Ubuntu.
Finally, I've launched GParted and see this:
Have I really just deleted all my Windows files? Looks like so. I know there's plenty of data recovery questions on AU, so mine will be:
What is Remove Ubuntu and reinstall option supposed to do, and why it has affected the Windows installation in such a way?
And of course, I didn't make any backups.
