I haven't written a blog for a long time. Yesterday I helped a colleague install a Samsung computer, which gave me a new understanding of system installation,

Record this and hope to help you.

As a computer enthusiast, installation is a required skill and a source of confidence that reflects your own abilities or understanding computers.

Model: Samsung ultra-thin, Samsung series 5 ultra 530u3c, with 24 gb ssd + GB

Hybrid hard disk composed of machine Hard Disks

Describe the installation process:

1. Use the UltraISO software to create a 32-bit USB flash drive for pure win7.

2. Restart the Samsung computer. F2 enters the system BIOS settings and sets the fast bios mode to DISABLED (not set,

The USB flash drive cannot be detected in the BIOS). Set the boot sequence to USB flash drive priority. Press F10 to save and exit, and restart to load files from the USB flash drive.

3. After step-by-step operations, I went to the place where I set partitions. Because the previous computer partitions were messy, I directly deleted all partitions,

Then we saw two hard disks on the partition panel. This is a mix of 24 gb ssd + GB machine hard disks.

Hard Disk, I feel like win7 is more resource-consuming, and it is divided into 50 GB on the machine's hard disk, and then the system is installed in this partition,

Everything goes smoothly. After data replication is complete, the system cannot be started upon restart.

4. I thought it was not installed properly during installation, and then re-executed Step 3. A strange thing happened to the partition,

Under normal circumstances, windows installation will automatically partition MB space as the system boot file storage, such as MBR

Information, the boot menu BCD is all in this partition, but I see this m partition appears in SSD. This

The problem occurs. The SSD hard disk is blocked in the BIOS and only the mechanical hard disk is visible.

In SSD, boot fails because the boot partition cannot be found after BIOS is started and the error bootmgr-is-missing occurs.

5. I also came up with an idea. Since SSD is available, why not install the system into SSD?

The software is not installed in the mechanical hard disk. Therefore, considering the feasibility of this method, I will repeat the third part,

This time, the system is installed in the SSD and cannot be started. The Boot partition is still created in the SSD.

Step 4.

6. solution:

Since the system cannot detect SSD, it is impossible to put the boot partition into SSD.

Import the partition to the HDD.

The following solutions:
Tool: a USB flash drive PE made by old Mao Tao, Bootice software (edit the System Menu startup software), and put the Bootice software into the USB flash drive of PE.

Steps:

A. Use PE to enter the system, open the diskgenius partition software, delete all partitions of the HDD, and split them into MB.

Is greater than or equal to the boot partition size of 100 MB.

B. Right-click the M partition in the SSD, select the clone partition, and then select clone to the partition just separated.

(Partition of the mechanical hard disk, MB ).

C. Open the Bootice software, select BCD, and browse and find the BOOT in the cloned BOOT partition of the HDD (MB ).

In the BCD directory, and then select advanced editing mode. The System Startup Menu editing box is displayed. In the Application objects

The directory under is the boot menu. Normally, Windows 7 is displayed. Click Windows 7 and the edit button is displayed on the right.

The ApplicationDevice option specifies the drive letter of the win7 system.

Drive letter, specify the partition installed in win7 system to enable boot. As in step 5 above, my system is installed in SSD,

The drive letter is disk D. Double-click ApplicationDevice. The edit box is displayed. Find the disk (My SSD) and find the system installation.

The partition of the d disk. After confirming, the BCD is edited.

D. Delete useless boot partitions. It's okay not to delete these partitions. It will not be started from here anyway. Method: Use

Diskgenius: select this partition and delete it.

7. restart the computer and boot normally. The system installation is complete.

Note: My SSD is relatively small, so after installing the system and installing some necessary software, it takes about 14 GB.

Any software should be installed on other disks. Otherwise, the system may cause many exceptions due to resource shortage.

In fact, the desktop is stored in the system disk. ---> This is only for my disk.
