Win7 install Ubuntu (Dual hard drive)

Preface

Previously in the virtual machine to use Ubuntu, feel the virtual machine and physical host still have differences, want to install Ubuntu under the WIN7, because I am a double hard drive, the middle of a pit, recorded here, can help others better. First introduced the situation of a own machine, dual hard disk (a mechanical hard drive + an SSD), Win7 installed in the SSD, want to install Ubuntu in the mechanical hard drive. preparatory work

The first thing you need to do is prepare for the following tasks:

(1) first to the Ubuntu website to download a mirrored file, and then download a EASYBCD (2.2 or more) software;

(2) Use UltraISO and U disk to make a startup disk;

(3) Use the Windows system's own Disk Management tool to compress (or delete an existing) volume to get an idle (or unused) disk, if it is a dual hard drive and Ubuntu wants to be mounted on another hard drive, Then you need to compress a 200MB free disk from the hard disk on which Win7 is located and use it for/boot partition to start installing Ubuntu

And then start installing the system,

(4) Reboot from U disk, start installing Ubuntu;
(5) partition, set the disk where the boot boot is installed;
(6) After installation, reboot to Windows, use EASYBCD to add system boot.

There are several things to note during the installation:
On the Installation Type page, select a custom installation

Then, when partitioning is performed on the custom installation page, if your machine is a dual hard drive, remember to set the/boot partition to the disk on the first system's boot partition (the 200MB disk mentioned in step 3rd), and the rest/,/home, and swap can be placed anywhere on two hard drives.
The hard disk partitions after my final installation are as follows:

Disk 0 is the SSD where Win7 is located, Disk 1 is the mechanical hard disk where Ubuntu resides, and 200MB of space is zoned on Disk 0 for Ubuntu's/boot partition and the boot of the partition is added using EASYBCD. about problems with boot failure after system installation

If you have a dual system and a dual hard drive, it is very possible to encounter this situation, because at the beginning of boot on the hard disk A, and your system installed on the other disk, so that the use of EASYBCD to guide the past is not good, the specific performance is the black screen plus the upper left corner of the cursor, because of errors across the disk boot.

WORKAROUND: Use the Disk Management tool under Windows to compress 200M space as a/boot partition in disk A (that is, the first system's boot partition on the disk), reinstall Ubuntu, install the 200M free spaces as the/boot, and the rest/ Home and/or anything can be put on disk B or disk A. Windows system time error

After installing Ubuntu again, you may find that Windows system is having a problem with the time format of Windows and Ubuntu, and win uses UTC using Rtc,ubuntu. can refer to resolving windows and Ubuntu dual system time synchronization problem

Start Ubuntu, open terminal (Turn off UTC)

sudo vim/etc/default/rcs

Find Utc=yes this line, change to Utc=no, save exit can.
