Home / how to install windows 7 through usb 3 How to install windows 7 through usb 3 14/10/2021 Recently I came across a problem when attempting khổng lồ install Windows 7 onto a Dell Precision 7710. I would boot up with a DVD that had an .iso image of Windows 7 installed on it, but when after clicking the install windows button, I would get a notice that the installer couldn"t locate the CD/DVD driver và I needed to browse to locate it. Well, I thought I would be smart và instead bởi the install via a USB device. Same error. Well, how does this make sense? It"s asking for a DVD driver when using a USB device. That"s like your oto throwing a CEL for the carburetor not working when you"re using fuel injection. This issue is caused because the installer media doesn"t have a driver khổng lồ install through a USB 3.0 port. You might ask, well why did the DVD drive throw the error? Well, that"s because the DVD drive sầu was an external because there is no internal DVD drive sầu on this mã sản phẩm laptop. So I now know my problem. USB 3.0 drivers need to be added to lớn the boot media. Follow this guide và I"ll show you how lớn accomplish this using the CMD line & the DISM utility.You watching: How to install windows 7 through usb 3 Now, I had all intention of describing this how-lớn specifically for adding USB 3.0 drivers, but it can also be used for adding any number of drivers to lớn the boot truyền thông as well. First thing you"re going khổng lồ vị is lớn tải về the USB drivers from either your computer"s manufacturer or from your motherboard"s manufacturer. With the Dell Precision 7710 I went to lớn http://www.dell.com/support, punched in my service tag number và proceeded khổng lồ download an entire driver pack in .CAB format. Depending on the type of tệp tin you downloaded, it could be an .exe pháo, a .cab, or a .zip, so you"ll need lớn unzip the drivers out of this file. Driver files are historically mainly .inf files, but you don"t need to piông chồng and choose the individual files because this next process makes it automatic for you. The DISM (Deployment Image Servicing và Management Tool) is smart và will automatically grab the correct files.1. Create a folder on your desktop named "Drivers".2. Create two folders inside of the "Drivers" folder, "mount" & "USB".3. Extract or copy/paste the driver files directly into the "USB" folder. I used 7-zip lớn extract my driver files directly inlớn the "USB" folder. Locate these two files from within your boot media. This is easy if you are using a USB drive sầu instead of a DVD, so that you don"t have khổng lồ reburn the DVD once we finish modifying these files.Example: If the USB drive sầu is plugged in & has been given drive sầu letter "P:" you will locate the "boot.wim" and "install.wim" files within the path: P:sourcesIt is best khổng lồ just cut them out of the install truyền thông, but if you want khổng lồ have sầu a backup copy you can copy & paste. You are pasting inlớn the "Drivers" thư mục on the desktop. Just make sure to overwrite the old files with the new updated ones once we"re finished with this process. Step 4: mở cửa up CMD prompt as Administrator and navigate to the 'Drivers' folder on the desktop Windows 7:1. Start, type in cmd, right cliông xã on the icon & choose Run as AdministratorWindows 8:1. Windows Key + Q.2. Move sầu mouse to lớn top right corner và tìm kiếm, type in Command Prompt, Right cliông xã và Run as Administrator.See more: Bảng Chấm Công Trên Điện Thoại Nhất Cử Lưỡng Tiện, Top 5 App Chấm Công Trên Điện ThoạiNext, you will need to change the directory path so that it isn"t pointing lớn the mặc định of C:WindowsSystem32.Type in: cd C:Users\%currentuser%DesktopDrivers - Then press Enter.*Note: Make sure khổng lồ change the %currentuser% khổng lồ that of the user profile where the "Drivers" folder was saved. In the cmd line now displaying the cd pointing to the right directory, type in these commands pressing enter after each one.dism /mount-wlặng /wimfile:boot.wlặng /index:2 /mountdir:mountExplanation: This command mounts the boot.wyên tệp tin, index points it to the correct boot parameters for the correct OS, & /mountdir:mount points it lớn mount the file lớn the "mount" thư mục we created in this directory earlier.dism /image:mount /add-driver:"USB" /recurseExplanation: This comm& automatically grabs the driver files that it locates in the "USB" thư mục that we created earlier and copied the drivers lớn. This can take a while depending on the number of driver files that it locates.dism /unmount-wyên /mountdir:mount /commitExplanation: This commvà unmounts the boot.wyên ổn tệp tin and saves the information. Think of this as a tệp tin transfer/compression process. Step 6: Determine which index you're going lớn update the driver files for on the 'install.wim' file This process wasn"t necessary on the "boot.wim" tệp tin, but it is in the "install.wim" file. Each version of Windows can have a specific index number và we will need to locate which one it is in order khổng lồ issue the command for the version of Windows you plan on installing. This is specific lớn the install media you are using because some install truyền thông media only comes with one version of Windows 7, such as Professional, but some others may have multiple version of Windows 7, such as trang chủ, Ultimate & Professional, just lớn name a few. Issue the following command to determine what your version is:dism /Get-WimInfo /WimFile:install.wimYou"ll see in the screenshot that I have sầu an index of 1.See more: Cách Tính Lãi Suất Kép Theo Tháng, Theo Quý, Ngày, Tính Lãi Kép (Lãi Cộng Dồn) Online You should still be pointed to lớn the correct directory, so now issue the following commands to update the "install.wim" tệp tin, using the index information you got from the step above sầu.dism /mount-wyên ổn /wimfile:install.wyên /index:1 /mountdir:mountExplanation: All exactly the same as the boot.wyên ổn file comm&, except the index is the only difference. dism /image:mount /add-driver:"USB" /recursedism /unmount-wyên /mountdir:mount /commit Since I used the Cut/Paste method to remove sầu these two files from the P:sources location, I"m going to lớn vày the same khổng lồ remove them from the C:Users\%currentuser%DesktopDrivers thư mục and place them baông xã into lớn the P:sources folder. Wait for the transfer to lớn finish. This is going khổng lồ take a little bit longer khổng lồ copy bachồng over to the flash drive sầu because the files going baông chồng in are larger than they were before due lớn the driver files that you"ve sầu added to lớn it. Take out the flash drive sầu và pop it inkhổng lồ the machine you want khổng lồ reinstall Windows 7 on. You should now find that you no longer receive the pesky CD/DVD driver missing notice. Thank you all for reading through this. These commands can be adapted to lớn suit whichever folder names you want to lớn use. Good luck!
