UK Update Nightmare

This article assumes that because it is easier to install various webserver, databases, Redis cache, MQ and other software, I have been using Ubuntu Kylin as a development system for a long time.
And today (2015-07-23) 2 o'clock in the afternoon, the system prompted a new update package, so it was updated, remember that only one core components of the update, the update required to restart the system. So the restart, but at this time the trouble has been quietly to!
When the system restarts, the interface of selecting the operating system cannot be displayed! Only one cursor in the upper left corner flashes on a black screen! Waited for more than 10 minutes or so, I was cold sweat dc, you know, nearly a year of various documents and code are under the UK system Ah, for various reasons, a large part of the time has not been backed up and checkin to version management tools. At that time, thought, if the system can not recover, but it is over, so long the efforts of all the wasted.
You know, the UK 14.10 system has been used for almost a year, a large and small update dozens of times, I remember the core components have also been updated several times, today, the swelling will appear this situation.

Press open key, direct violence shut down the computer, after a few minutes to start the machine again, or the same black screen interface! My heart in the blood, that moment, how much emotion poured into my heart, the real mixed feelings ah. Thinking for a while, still without a clue.
Fortunately, there are several computers at hand, I hurriedly use other computers to the UK official website to see, found the official QQ group number and forum, joined in, and posted in the forum, asked what is the answer, too scary. QQ Group at that time someone said, re-install the system bar. I said, no ah, nearly a year of information and code are in the inside, can not be re-installed. My head at the same time in the fast running, really not, can only hold the computer to the UK company, let them to restore the system.

Then I said in the group of the computer, the installation is Win7 and Ubuntu Kylin 14.10 Dual system, installed in the Win7 under the production of U-disk Startup Disk mode of installation, with the EASYBCD 2.2 set under the Win7 of the dual system start. Finally, my computer is a 64-bit system.
Later I think, is not the update core components when the root partition boot sector what is broken, because found that the Win7 system can also start running normally.
At this time some people give advice, said increase Neogrub try, for a moment no clue, try to add a bit of neogrub, but I do not know what this is a thing, instinctively feel so dangerous.
Suddenly, a flash in the head, a netizen on the front said a sentence, in the EASYBCD add a new entry, I try to "Add New Item" option, add a bit, such as:

And think, yes, it should be. After the UK has updated its core components, the EASYBCD running under Win7 cannot find the portal that was originally launched, so it will cause a black screen at startup, and a new boot entry should be re-specified.
So I saved the settings and tried it boldly. Reboot, select dual system ubuntu Kylin 14.10 Startup Item ...
Wow, Success! The UK system can be restarted!
Later, I saw in the UK official forum A reply: Ubuntu/uk is started with Grub management, may update this part, causing EASYBCD read errors, reset the next EasyBCD try.
Although I did not how to toss and Daoteng UK, incredibly also consider this situation, the moment feel a little smug, hey.

The final conclusion is that backup systems are critical! Don't be lazy.
