"Practice Process"

---------------Solemn hint: The practice process record, for reference only, welcome message exchange---------------

1. Environmental damage

Original environment:

　　HDD--Windows7

SSD--WINDOWS10 + windows7

Windows7 installed Ubuntu16.04 on HDD, the installation started correctly, but failed to repair Windows system boot.

2. Resource record:

U disk making tool Win32diskimager

Https://wiki.ubuntu.com/Win32DiskImager  

Bugs that exist with other tools

3, re-install the system, the results of repeated verification:

1) Two HDD, only one hard disk (HDD) can boot the system, another m.2 interface SSD disk failed to boot the system successfully;

2) The Windows system can be installed on the SSD, through HDD drive boot;

3) Ubuntu installed on SSD can not boot through HDD hard drive, the Ubuntu system installed on HDD is possible;

4) Subsequent operations require that the boot partition (the first partition of the HDD hard disk) be retained, without causing the system to be compromised.
