UK updates and uk updates

UK updates and uk updates
The premise of this article is that, because it is easier to install various software such as webserver, database, redis cache, and mq, I have been using Ubuntu Kylin as a development system for a long time.
Today () at two o'clock P.M., the system prompts that a new update package is available, so it is updated. Remember that only one core component is updated, and the system must be restarted after the update. So I restarted it, but now the trouble is coming!
When the system is restarted, you cannot find the Operating System Selection interface displayed! There is only one cursor in the upper left corner flashing on the black screen! I waited for more than 10 minutes. At that time, I was cold and sweaty. I want to know that all the documents and codes in the past year were under the uk system. For various reasons, A large part has not been backed up and checkin to the version management tool in time. At that time, I thought that if the system could not be recovered, it would be over, and the painstaking efforts of such a long time would be exhausted.
You know, the uk 14.10 system has been in use for almost a year and has been updated dozens of times, both in size and size. I remember that the core components have been updated many times. Is it possible to see this situation today.

Press the key and shut down the computer. After a few minutes, start the machine again. The same black screen is still displayed! My heart is bleeding. At that moment, I feel a lot of emotion. What is the real intersection of feelings. After thinking for a while, I still have no clue.
Fortunately, there are several computers at hand. I quickly used other computers to check them on the uk official website. I found the official button group number and forum, joined them, and posted a post on the forum, it's terrible to ask what is going on here. Some people in the group said at the time, reload the system. I said, no. The materials and codes for the past year are in the middle and cannot be reinstalled. My head is running fast at the same time. I can only hold my computer to go to the uk company and let them restore the system.

Then I talked about the computer situation in the group. I installed the win7 and ubuntu kylin 14.10 dual systems. During the installation, I installed the USB flash drive on Windows 7, use easyBCD 2.2 to enable a dual system in win7. Finally, my computer is a 64-bit system.
Later, I wondered if the root partition startup sector was broken when I updated the Core Components, because I found that the win7 system can still start and run normally.
At this time, some people in the group gave a suggestion, saying that adding NeoGrub was a try, and there was no clue at the moment. I tried to add NeoGrub, but I didn't know what it was, and I thought it was very dangerous.
Suddenly, my mind flashed, and a netizen said, adding a new entry in EasyBCD, and I tried to add it to the "Add a new entry" option, for example:

Then I thought, right, it should be that after uk updated the Core Components, EasyBCD running in win7 could not find the original startup entry, which would cause a black screen status during startup, you can specify a new startup entry.
So I saved the settings and tried it. Restart and select the dual-system Ubuntu Kylin 14.10 startup Item...
Wow, success! The uk system can be restarted!
Later, I saw a reply on the uk official forum: ubuntu/UK started management with grub and may have updated this part, resulting in an easyBCD read error, try Setting easyBCD again.
Even though I did not go through the uk, I thought about this situation and felt a little smug in an instant.

Conclusion: The backup system is crucial! Never slack off.
