I will give you one option I know would work, but it involves booting from a full install CD / ISO and using rescue mode to gain access to your boot volume and Grub. Here is what you would do to start.
我将为您提供一个我知道会有用的选项，但是它涉及从完整的安装CD / ISO引导，并使用营救模式来访问您的引导卷和Grub。这是你要开始做的事情。
- Boot from a full install CD and choose the menu option for rescue mode.
- 从一个完整的安装CD引导，并选择菜单选项的救援模式。
- go to your boot volume where Grub is located, usually in rescue mode your old file system is on /mnt/sysimage
- 进入Grub所在的引导卷，通常处于救援模式，您的旧文件系统处于/mnt/sysimage
- Find and edit /mnt/sysimage/boot/grub.conf to increase the timeout and unhide the menu using the following commands within grub.conf.
- 查找和编辑/ mnt / sysimage / boot / grub。conf使用grub.conf中的以下命令增加超时并解除菜单隐藏。
Grub.conf
Grub.conf
timeout=20
#hiddenmenu
Reboot from the hdd this time and when grub shows up choose the previous working kernel and that should boot. You will be back on a previous kernel and possibly release, but you will have a system to at least back up and retry the upgrade.
这次从hdd重新启动，当grub出现时，选择之前的工作内核，应该启动。您将回到以前的内核并可能发布版本，但是您将至少拥有一个系统来备份和重试升级。

I was getting this when attempting to install 13.10 and it turned out to be incorrect usb formatting in my case. my usb stick was formatted to NTFS and I would get this error every time I tried to boot from it. Once I formatted the usb stick to fat32 the installation worked like a charm.
当我尝试安装13.10的时候我得到了这个结果，结果证明我的usb格式是错误的。我的u盘被格式化为NTFS，每次我试图从它引导时都会得到这个错误。一旦我将u盘格式化为fat32，这个装置就像一个咒语。
Hope it helps!

The same problem happened to me and here is the easiest way to solve this problem so as to get a bootable system. The first thing you need to do is, try to boot in a recovery mode as explained here. Once you get the root prompt, execute the following commands.
同样的问题发生在我身上，这里是解决这个问题的最简单的方法，这样就可以得到一个可引导系统。您需要做的第一件事是，尝试在这里解释的恢复模式中启动。得到根提示符后，执行以下命令。
$ sudo update-initramfs -u
$ sudo update-grub2
$ sudo reboot
Hope this helps.
