Windows 8 / Ubuntu“其他安装类型”后，多重引导不起作用

昨晚我通过选择“其他”作为安装类型，在已经装有Windows 8的HDD上安装了Ubuntu 13.10。

• sda1可能是主要的NTFS分区（不确定，因为Windows 8安装程序已创建它）
• sda2是一个主要的NTFS分区（我在安装Windows 8之前在Ubuntu GParted上创建了它）
• sda3也是如此（即sda2）
• sda5是交换区分区（我不记得是选择逻辑分区还是主分区，但GParted表示逻辑分区）
• sda6是逻辑ext4分区
• 最后一行只是空闲的未分配空间

As I wrote earlier, all partitions were created with a Live CD with Ubuntu's GParted but the sda1 NTFS [Windows 8 (loader)]. And all of the partitions I created I used for "location of the new partition:" the option "beginning of this space".

For the Ubuntu partition I chose / as a mounting point. There was a warning saying something like "everything will be deleted on that partition … do you wish to continue?" and I said yes.

At the end of the installation there were other warnings. I didn't care to look at them and I clicked OK until the computer restarted. When it did, Windows 8 booted instead of GRUB, meaning that I can't access Ubuntu.

When I boot the computer with Live CD Ubuntu and check gparted I get this:

According to gparted sda1 is a primary partition as well

Can anyone please help me?
