Unable to set CD drive bit hard drive boot, make dual Drive dual system boot Menu

The first two days to replace the CD-ROM drive, tossing a long time to fix the dual system, here Memo:

The optical drive is broken, and there is a hard drive that was previously removed from the notebook and is going to be mounted on the drive:

My notebook is Sony, that need to install to the CD-ROM drive is removed from this notebook, there is a genuine Win7 system, but a long time no use.

Since the optical drive is broken, buy an optical disk drive tray, put that hard drive back to use Bai.

After putting the hard drive back on, I thought I could start the system from the CD-ROM and get into the system of the previous hard drive. But found that the notebook is not supported from the CD-ROM bit boot system! Although booting from the main hard drive, you can see the hard drive information installed in the optical drive bit, also can use. But if the system can not enter the optical drive, I can not use the dual system, ah, I also plan to use that genuine win upgrade into WIN10 it!

It is not difficult to solve this problem:

There is no need to set the CD-ROM bit to start, just make a dual system boot menu.

To download a two-system boot menu Repair Tool online, there are many, can be found anywhere on the Internet.

Start the Repair tool, click on the "Automatic repair", restart the computer, you can see the boot system when there are two systems for you to choose! This allows you to choose which system to turn on when you boot.

About the selection of the optical drive bit system, a post is very good. Recommended: http://bbs.zol.com.cn/nbbbs/d160_149254.html#
