win8 win7 system teletext system to the system to the win7 system

win7 desktop

a, first of all to download win7 ISO image;

Second, make U disk;

Prepare 8G or above U disk, download Chinese cabbage.

Using Chinese cabbage tools to make U disk (this step is easy, it is no nonsense)

Three: Restart win8, find BIOS (emphasis);

Nonsense: < Br>

It is found that many students are stuck here. When restarting, whether it is delete, or F2, F10, F8, etc., a mad press, but it does not work. . . Expected BIOS did not appear, damn win8 welcome interface came out. . .

Solution:

1. Start up win8

2. Press the key combination after booting completely “win+i”

3. A list of options appears on the right side (never used win8, which means I don't know if this is God Madong)

4. Click “Change PC Settings>, this will jump to <;Computer Settings” Page

5. Click “General”--">;Advanced Startup --"Restart”

After rebooting, it will go to “select an option interface”

7. Then select “Troubleshoot"--">;Advanced Options"--";UEIF Firmware Settings”

8. At this point, restart and automatically enter the BIOS interface.

Fourth, set the U disk boot;

UEFI BIOS supports two boot modes: Legacy BIOS boot mode and UEFI boot mode. Some devices and operating systems do not yet support UEFI-based BIOS, so they can only boot from Legacy BIOS boot mode. Depending on your situation, you may have to specify the UEFI BIOS boot mode to use: Legacy BIOS boot mode or UEFI boot mode. Select Legacy BIOS boot mode to allow the HBA and Express Module devices to use the option ROM. Select the UEFI boot mode to use the UEFI driver.

Solution:

1. In the BIOS, select “Security”

2. Under “Security” select“Secure Boot” and Change the status to “Disabled” (Note: This step directly affects whether step 4 is operational)

3. Press ESC to return to the previous level and find “Startup”

4. Select UEFI/Legacy Boot under "Startup" and change its status to “Legacy Only"

5. Also select Boot under “Startup” and follow the prompts to “USBHDD” Adjust to the first position (priority U disk boot, if it still does not work, turn all other USB heads to the front)

6. Press F10 to save and exit and restart. Already inserted... Yes, insert...)

Five: Depth formatting the disk, modify the partition table type (Note: This step is dangerous, please backup important files first (love action movies, etc. ), if you have any mistakes, you are not responsible for it)

Nonsense:

When you enter to choose to install When you go to a certain disk, due to the different types of disks, you will be prompted: "The selected disk cannot be installed in the GPT partition format". At this time, you need to reset the partition form (formatting can't solve the problem)

Solution:

1. Press “shift+F10” to enter the DOS command line

2. Enter diskpart Enter--for partition operation

3. Enter select disk 0 Enter--Select the disk to be operated

4. Enter clean Enter--Depth Format the disk

5. Enter convert MBR Enter -- convert the disk to the MBR partition form.

6. Exit DOS and refresh
