安装期间无法识别现有分区

我的电脑上安装了 Windows 8（最终版本，无预览版）。现在我想安装 Ubuntu，就像我以前做过一千次那样。奇怪的是，gparted（从实时 USB 启动）将我的系统磁盘视为完全未分配，尽管它有一个巨大的 ntfs 分区，上面有 Windows 8。因此，我再次启动 Windows，并使用磁盘管理工具缩小该分区并在可用空间中创建一个新分区。我将其格式化为 fat32。我仍然遇到相同的行为gparted。有人知道吗？我的硬盘是三星 830 系列 SSD，主板有 UEFI。

现在尝试了 12.10 beta1 棒。它告诉我该卷包含 GPT 签名，可能被无法理解的程序损坏了。通过这些新信息，我发现这但我真的不知道该怎么做。

我找到了解决方案这里.基本部分是：

OK, then, it looks like you've got a new MBR with residual GPT data, which is confusing GParted. You'll have to wipe the GPT data. Here's how:

Boot your PartedMagic or System Rescue CD emergency disc.
For safety, back up your MBR by typing "dd if=/dev/sda of=sda-backup.mbr bs=512 count=1" and then copying the resulting file (sda-backup.mbr) to a USB flash drive, network share, or some other medium. Be sure to get the if= and of= parameters right, though!
Launch gdisk by typing "gdisk /dev/sda". When asked whether to use the MBR or GPT data, either will work.
Type "x" to enter the experts' menu. The command prompt should change.
Type "z" to "zap" (destroy) the GPT data. Tell it to proceed, but answer "N" to the question about blanking the MBR.

That's it. Windows should boot as it did before and you should now be able to continue your installation of Ubuntu; its installer should now see the same partitions as Windows.
