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.

Boot display bootmgr is missing, do not enter the system, the computer disk does not have a drive, how to use a USB flash disk to install Windows 7

3. Download Windows 7 online and place it on a USB flash drive. Install it as instructed.

Unable to enter the system. The above two items can only be performed on another machine! For reference!

You cannot start the system or boot the installation system.

One reason for the failure to Access Windows XP is hardware failure. At this time, we have to listen to the abnormal sound when starting the Windows XP system. The other reason is the Windows XP system, at this time, restart the computer, press F8, and use the "Restore the last correct configuration" function to check whether the system can be accessed. If not, find a boot disk, check whether you can access the Windows system.

Hardware reasons

First, start your computer and enter the BIOS to check whether your hard disk is displayed in your CMOS. Make sure that your hard disk is detected by the computer, after the new boot, the computer still cannot enter the operating system, and some English appears in the place where the Dos is stopped. Is information about the DISK. Set your computer as a floppy disk to start.

Boot Disk of Windows 98 to enter DOS. Enter the fdisk command after A: \ to check whether your partition exists. I have encountered some computers, and the hard disk has deleted all hard disk partitions for no reason and turned them into a hard disk with no partitions and no formatting. After you confirm that the disk is still partitioned, please install the operating system again. After installation, you can. Solve the problem.

Cause: there are many causes of the problem, generally due to the following reasons.

1. It may be caused by the loss of boot files in your operating system. This problem occurs generally because you use software such as Word or Baidu, in the directory of drive C, you may delete the boot file of the operating system when you think the software is not available. Solution: do not install the software in the directory of drive C. This problem should be avoided again.

2. caused by viruses or hacker programs. To avoid this problem, only genuine anti-virus software is installed and upgraded in a timely manner.

Software reason: Windows XP SP2 cannot enter the system after restart

Some users cannot access the system normally after installing the SP2 patch in WINXP, which is due:

1. The computer uses the Stepping C0 processor of the Prescott core, including the CPU of P4 and celeon D.

2. the BIOS version used on the motherboard is too low. This BIOS may not be suitable for your CPU.

To solve the problem, follow these steps:

1. reboot or restart the system, insert a Windows XP boot floppy disk or boot CD, press the DEL key to enter the BIOS, and choose to start from the boot floppy disk (XP boot floppy disk) or the CD (XP boot CD ), on the Setup interface, select "R" to enter the system recovery platform;

2. enter the problematic code (displayed in front of C: \ Windows, such as in a red circle) and press Enter, the superuser password interface appears. Enter the password and press "Enter" (Press Enter without a password );

3. After step 1 is executed, the "C: \ windows" DOS prompt will appear. Enter cd system32 \ drivers at the DOS prompt, press Enter, Enter ren update. sys update. sp2, and press Enter;

4. Enter Exit and press Enter to Exit DOS and Enter Windows XP;

5. In Windows, click the Start Menu> Settings> Control Panel> add or delete a program to delete SP2;

6. check whether a new BIOS exists on the website to solve the problem. If yes, update the BIOS and reinstall SP2. If no BIOS is available to solve the problem, use SP1 first. And observe the new BIOS released by our website.

Summary

There may be many reasons for failure in Windows boot, memory problems, motherboard reasons, system faults, and so on. Hardware faults cannot be avoided, but we can still avoid software faults, that is, we often back up the system .... Remaining full text>
