If you want to install Windows 7 on a USB flash drive PE, you can install XP, VISTA, or Windows 7 on a USB flash drive PE. Please do not use the PE on the old wooden peach because the USB flash drive cannot be installed in ZIP mode, we must download the disc image PE. Remember it's an optical disc PE !! There is not much nonsense. There are only two tools. One is a PE optical disk image file. http://www.wzlu.com/soft/17/2009/200903177324.html And the other is UltraISO. http://www.onlinedown.net/soft/614.htm [Registration Code: Li Ming 509F-BA54-BBA6-73C5] All the above three have been downloaded. you have to spend money to buy a USB flash drive. It is best for everyone to buy a 1g drive. This is a waste of money. 4. Start to make the following: after UItraISO is installed on www.2cto.com 1, enter the registration code [above] 2. It is required to insert a USB device! My SD card and card reader! Easy to test! 3. Use UltraISO9.2 to open "2009 New Year's optical drive PE", click "Boot disc", and select "Write hard disk image ". 4. On the "write to hard disk image" Page, select the "hard disk drive" and the USB flash drive you want to install PE. (do not select an error. Generally, it will be automatically prioritized ); select ZIP mode for "Write mode". 5. Click "format" (select FAT or FAT32 format as needed). I select FAT32 and some mainboards, it may be better if you choose FAT16! Click the "write" button, and then exit after the write is complete. Five major achievements: you can install XP, vista, and Windows 7 as you like. You do not need to unplug USB flash drives, copy startup files, or load image files normally, click Install .................. Conclusion 6: 1 some say that the HDD mode is also acceptable. I have no objection to the HDD mode, but in the HDD mode, the system will automatically recognize the USB flash disk as a drive C partition, the consequence is that the system boot file is copied to the USB flash drive, unless you write the system image file to the USB flash drive in HDD mode for DOS installation, however, if you pay more than 2 GB of USB flash drives, the current motherboard generally supports the ZIP mode. However, some old motherboards may not support the ZIP mode, but the production speed may be faster, for specific co-production methods, please refer to Baidu. Remember to find a production tool of the corresponding version during mass production, let's take a look at some successful and recognized posts. 3. As for how to load the system image file under the PE, find the virtual optical drive under the PE and load it in. Click the installation file. Then, OK and seven questions: for feedback on some motherboard problems, I will summarize one of the methods for installing Windows 7 in PE as follows: Download The win7 iso compressed package and load it with a virtual optical drive, because downloading iso is an encrypted compressed package, there is nothing to decompress directly, so we need to copy the content in the disk and store it in the root directory of the drive other than drive C. Folders, such as win7. Step 2: Use a USB flash drive to start the computer and enter the PE system. Step 3: format the C drive and decompress the ISO file to the "bootmgr" file in the win7 folder and copy the boot folder to the C root directory, create a sources folder under the C-drive root directory, and then boot the files under win7 \ sources. copy wim to the sourse folder on drive C. Step 4: Click start -- run --> cmd --> enter c: \ boot \ bootsect.exe/nt60 c: (Note space), restart, and dial out the USB flash drive. Step 5: restart your computer. Please wait ...... Step 6: Start the installer, select the language type you want to install, and select the appropriate time and currency display type and keyboard and input mode. The "Start installation interface" appears (note !!! If you do not click "Install now", click "repair my computer" in the lower left corner ). Go to "system recovery options" and select the last command prompt (command prompt). step 7 of the DOS window appears: Enter X (Disk of your installation file ): \ win7 \ sources \ setup.exe and press Enter. Then step 8 is the same as starting and installing the CD: Of course it is activated, and this kind of software can be found on the Internet. Good luck!
