I can confirm the bug with Ubuntu 13.10 on a Dell Inspiron 3721. It had Windows 8 pre-Installed, to which I had added Ubuntu 13.04 on a second partition. I had disabled UEFI and secure boot, because I hadn't managed to install Ubuntu with UEFI active back then.
When Windows was later updated to 8.1, the updater tacitly removed the grub bootloader, so I couldn't boot into Ubuntu any more. To fix that I chose to install 13.10 freshly. The installer offered me to update 13.04, or to completely replace 13.04 or to do something else. Under 'something else' there was no mention of Windows IIRC. When I chose to completely replace Ubuntu, the HD was newly partitioned, so both the windows and Linux partitions were scrapped and replaced by one large partition that filled the entire HD (and a small swap partition). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1259701 Title: 14.04 installer does not detect Windows 8.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1259701/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
