   One, BIOS boot:

1, the traditional computer is usually the use of BIOS boot, boot BIOS initialization, and then the BIOS self-test, and then boot the operating system → into the system, display the desktop.

2. CD Start:

In the case of BIOS booting, usually use the installation of the CD-ROM maintenance, installation of operational systems, as long as the CD-ROM (or DVD, motherboard menu is not the same) use the up and down key, select this, press ENTER (enter) to confirm, and then press the F10 key, restart the computer, you can recognize the CD-ROM

3, u disk start:

Under the guidance of the BIOS, U disk PE system operation and CD-ROM boot setup method similar, as long as the USB option (some motherboards are shown on the model), set as the first start, restart the computer will read U disk PE system.

  Second, UEFI guide:

1, UEFI boot process is initialized Uefi, and then direct the operating system, into the system. Compared with the traditional BIOS boot, UEFI boot is less than a BIOS self-test process, so the boot will be faster, which has become a new favorite of the computer.

2, for example, Acer's new computer default is UEFI guidance, if you need to use a U disk PE system, you may not recognize U disk, at this point to make some adjustments. Plug in the already made U disk PE system, boot fast (slow will read directly to the hard drive) press F12 key, enter the Setup interface. The following figure is the key value for each branded machine or motherboard to enter the BIOS boot setting (for reference only).

3, enter the main interface to set up, continue to click on the boot menu, boot mode (boot modes) Right is the current boot mode, where the default is UEFI boot.

4, select the entry, open the settings, there are two options: UEFI and Legacy (using the up and down key selected), boot mode select Legacy.

5, click OK, confirm the modification for legacy boot mode.

6. Ask if you want to reboot your computer now? Click Yes to reboot the computer and the boot menu will be displayed.

7, enter this interface, I believe that many familiar with the bios of the old users on the relief, the first (HDD) for the hard drive, the second (USB) for the U disk to start, the third (network) for the network boot.

8, set up a good U disk startup (USB), restart the computer will recognize has been made a U disk PE system. The next is a graphical interface, there are Chinese instructions, do not have to repeat it.

9. However, since the early production of the Win7 operating system has not seen the UEFI boot system, it does not support the GPT boot on UEFI boot (suitable for the WIN8 operating system), and MBR is incompatible with GPT, if you want to install the Win7 operating system, The disk must be converted to MBR boot. U disk PE system now has this kind of maintenance tools.

10. Note: Converting the disk format requires emptying all partitions and data on the disk, so be sure to save all the important data on the disk before you operate. After entering the WIN7 installation interface, you can also use the command to convert disk boot mode without using the Maintenance tool: press SHIFT + F10 to open the command prompt. Input: Diskpart Press ENTER to enter the operating interface.

11, Input: List disk Press ENTER to execute the command, you can view the relevant information on the disk. At this point you should look at the size of the disk to determine, select. The 465GB Disk 0 is the hard drive, 3852MB Disk 1 is for Win7 installation of the U disk (do not choose the wrong!).

12, Input: Select disk 0 Press ENTER, select Disk 0 for the current operation of the disks.

13, Input: Clean press ENTER, empty the current disk partition.

14, Input: Convert MBR press ENTER, the hard drive boot mode to the MBR partition. At this point, installing the Win7 operating system has no problem booting the exception.

15, after the operation completes, closes this command prompt window, continues to install the Win7 system according to the normal method.
