Why BIOS doesn’t see the bootable flash drive. how to fix it?
The owners of laptops are faced with a lot of different malfunctions. One of the fairly common are problems with the detection of removable media, namely flash drives or memory cards. Below we will find why the laptop does not see the flash drive, and how to fix the problem.
If a laptop does not see the flash drive, then you should consider two possibilities: the problem with the flash drive itself, or the malfunction is related to the gadget. First of all, you should discard the variant with the faulty drive. To do this, you can insert it into another device. To check your laptop, you should insert another medium into it. If it does not see any memory, then the source of the problem lies in the laptop.
The port is dirty
If the laptop does not see the flash drive, the first thing you should check whether there is debris inside the port. Sometimes a piece of paper or dust obstructs the connection. The device does not see the drive and you feel it is in the correct orientation. It is best to use a can of compressed air to clean the connector. They are sold in stores of home appliances.
Important! Never use a sharp object to clean the ports, it can cause damage.
The second possible cause is the action of viruses. In fact, it is unlikely, but it is still possible, so another check your gadget with an antivirus will not be superfluous. The problem may go away after cleaning the system.
Failure related to the driver, there are two types: sometimes the problem is in the sockets driver, and it may happen that the problem is the stick driver. In the first case the user needs to update the USB port driver. To do this you can download it from the manufacturer’s website, use utilities for automatic software search or find the necessary node in the “Device Manager” and in its menu select “update driver”. The last option is the most useless, because usually the system can not find the program it needs.
Important! And that’s what the “device manager” is useful. you can see if there is a problem with the ports or not. If there is a yellow exclamation mark next to “USB controllers”, then there is definitely no driver installed. Most often this happens after reinstalling Windows, but can also happen due to a malfunction or because of an upgrade of the operating system.
What to do if in the Device Manager there is no item “USB controllers”, or it does not show anything? In this case the problem may be that the system does not see the USB ports, which means that they are disabled in the BIOS. How to fix it. will be told a little later, but for now we should learn about a few more useful features, which are contained in the “Device Manager”.
USB port is disabled
Sometimes the problem with the fact that the device does not see the USB flash drive is that someone has disabled the port in Windows. This is done in the “Device Manager” by clicking on the “USB root hub” PCM, you can enable or disable it. In the latter case it will stop seeing the devices connected to it. from a mouse to a flash drive.
The last situation where the laptop may not see the USB device. the ports are disabled in the BIOS, or it is confused settings. You should know that it is not always possible to disable connectors in the BIOS, it depends on its type. To check if the problem is in the BIOS, you can do the following.
- Enter the Advanced menu (in BIOS) and look for the inscription which contains the word “USB”.
- If there is one and it says disabled, the ports are disabled. It needs to be switched to enabled.
- When you exit BIOS, it is necessary to save the changes.
- If there is no suitable option, open the Exit tab and find the line “load optimal defaults”, i.e. “load working settings”.
- After that, exit from the BIOS saving changes and check if the ports work.
What to do if the BIOS does not see a bootable Windows flash drive.
Why can’t it see the USB flash drive?? I specifically showed you on a laptop, but it’s good for PCs too. Problems in the UEFI boot system. You need to make a UEFI flash drive and install from that. To install Windows 7 from a USB flash drive you need to configure your BIOS to boot from it.

How to configure your BIOS for a bootable flash drive
First you need to understand if the stick is not visible in BIOS, i.e. you have no line “USB flash drive name”, or if you have a line, but when you click on this item you have nothing but a black screen.
There are two ways this can happen. your flash drive is faulty, or you didn’t write the image correctly, or there is a problem with your BIOS, so the BIOS can’t see the stick. First, read the material on configuring the BIOS to install Windows.
The best option is to boot from the flash drive. Boot Menu. You can enter it by pressing ESC, or F8. It’s different on different devices, so read the article first. Open the Boot Menu and you’ll see a list of devices you can boot from. flash drives, hard drives, CD-DVD. You need to find something like Kingston 8 GB USB or similar, depending on the brand of your flash drive.
If you don’t have a Boot Menu, or it is disabled, then in the BIOS on the Boot or Advanced tab you need to put your flash drive in first place. Can be done by pressing F5 and F6, but again, every model has different parameters, you need to figure it out yourself, or write to the Комментарии и мнения владельцев, so I can help you. For example, here are all the details about the HP Pavilion notebook BIOS.
Once you put the stick first in your BIOS, press F10 to save the current BIOS settings. Or on the tab Exit choose the option Save Changes and Exit.
Second place after flash drive should be hard disk drive, but after that other devices.
Finally you may reset your BIOS if none of the above help. Follow this link and read about it. Usually the reset option is on the Exit tab, or a little differently, called Load Optimal Defaults.
Let’s summarize the above and tell you why the BIOS doesn’t see the bootable flash drive:
- The USB device is defective. Use a different flash drive, or try it on a different PC.
- Wrong program for creating a bootable flash drive was selected.
- The image recorded on the USB stick is damaged and must be replaced.
- The BIOS settings are wrong, you need to reset it.
- Your BIOS does not support booting from flash drives (it happens), so update your BIOS.
If you had this issue with USB flash drive, then try to create a disk with Windows or a program on it. About the BIOS update, I would like to point out that you need to be very careful. First, you need to find the correct firmware that fits your motherboard, if you choose the wrong version, or from another board, then there is a high probability of failure of the entire motherboard, and you certainly do not want that. So be sure to make a backup of the bios before you do the update.
Configure your computer
Even if the device supports booting from a USB flash drive, keep in mind that it is not always set as a priority in the BIOS. You need to configure this function. So first make changes to the BIOS setup. Perform the following steps:
- Restart your computer or, if it is already turned off, turn it back on.
- When the PC starts working you will see on the first screen a key to enter the BIOS setup. Most often it’s “F2” or “Del”. The key varies depending on the model of your computer. For example, Dell devices have different ways to enter BIOS.
This lets your computer know you want to boot from your flash drive. Plug it in and reboot the machine.
Important! In different versions of BIOS all items and partitions may have different names.
Rebooting from a USB stick with an old BIOS
Users with older computers can boot from a flash drive in the same way, although the rules may be different.
For example, with a Lenovo laptop you can get into the BIOS by pressing F2. After that go to “BOOT” menu.
Save and reboot your notebook. From now on it is bootable from this very device. Most of the older laptops have this model BIOS, so it will work for 90% of the models.
BIOS does not see the bootable flash drive: How to fix it
In general, there is nothing better for installing an OS on your computer than a handmade bootable flash drive. You’ll be 100% sure it’s the right one. In some cases, it turns out that the media itself is not made correctly. So we will look at several ways to make it for the most popular versions of Windows.
In addition, you need to set the right parameters in the BIOS itself. Sometimes that can be the reason why the drive is not on the list of drives. So after we understand how to create a flash drive we will look at three more ways to configure the most common BIOS versions.
USB flash drive with Windows 7 installer
In this case, we are going to use Windows USB/DVD Download Tool.
- The first thing to do is to go to the Microsoft website and download a utility to create a bootable flash drive.
- Install it and start making the USB flash drive.
- Using the “Browse” button, which will open an explorer, specify the location where the ISO image of the operating system is located. Click on “Next” and go to the next step.
Select “USB device” in the window that says what type of installation media you want to use.
This will actually start the process of creating the drive.
This method is valid for Windows 7 and up. To write the images of other systems use our instructions for creating bootable USB sticks.
In the following instructions, you can see ways to create the same drive, but with operating systems other than Windows.
Configure Award BIOS
To enter Award BIOS press F8 at boot time of the operating system. This is one of the most common. There are also the following combinations to enter:
Now let’s talk about how to configure BIOS correctly. In most cases this is the problem. If you have an Award BIOS, do this:
Check that the USB controllers toggle is in the “Enabled” position, and if needed, toggle them.
Go to the “Advanced” section of the main page and look for “Hard Disk Boot Priority”. It looks like the one pictured below. Press “” on the keyboard, move to the top of “USB-HDD”.
This should look like the picture below.
Switch to the main window of Advanced again and set the “First Boot Device” switch to USB-HDD.
Go back to your main BIOS setup window and hit “F10”. Confirm your choice by pressing “Y” on the keyboard.
Configure AMI BIOS
Key combinations for entering AMI BIOS are the same as for Award BIOS.
If you have AMI BIOS, make these simple steps:
Go to the “Boot” tab and select the “Hard Disk Drives” section.
Move Patriot Memory to “1st Drive.
The result of your actions in this section should look like this.
In the “Boot” section go to “Boot Device Priority” and check that “1st Boot Device” is exactly the same as the result of the previous step.
If everything is done correctly, go to “Exit” tab. Press “F10” and in the window that appears. enter key.
UEFI is configured in the same way as BIOS.
This advanced version of BIOS has a graphical interface and you can use it with a mouse. To set it to boot from removable media, follow some simple steps, specifically:
In the selected partition set the “Boot Option #1” parameter with the mouse so that it shows the USB flash drive.
Now, armed with a properly made bootable flash drive and knowledge of the BIOS settings, you can avoid unnecessary worry when installing a new operating system.

BIOS setup for booting from a USB stick
Let’s look at an example of UEFI BIOS booting from a USB stick. For example we’ll use MSI motherboard A58M-E33 which has the latest UEFI BIOS. To enter the UEFI BIOS settings for the A58M-E33 motherboard, press the. You will see the boot menu, in which you select the flash drive, in this case it is “KingstonDataTraveler 2.0PMAP”.
You can also set the flash drive to boot directly from BIOS. To do this, when booting up, press the. You will enter the UEFI BIOS main menu.
Then go to the “Settings boot” menu and put your flash drive in first place, as shown in the picture below.
Your system will now boot from the selected flash device. But if your PC or notebook has UEFI and the system cannot see the USB stick, it means that the image is not recorded correctly, or “Safe boot” mode is on (to fix it see “How to use UEFI? section below “How to configure UEFI to”).
If you still do not have the correct media in the “Boot device priority” when installing Windows, here are a couple more tips:
- Try to boot from a system that is already installed, but has not yet been removed. Insert it and wait until it is detected. Afterwards, reboot and try to install.
- Connect the USB stick to the back of the system instead of to the front of the system. Try other ports.
- The old BIOS may have problems identifying USB hard drives. It may be because of its large size. In this case you need to find exactly the flash drive.
- The problem could be caused by simple copying of the image contents to the USB stick. This might not make it bootable in particular. precisely this option may work for EFI mode, but only for creating an image of Windows 10. On 7 you will need to do a couple more things to make it work. The easiest way is to use Rufus, the program I mentioned above or read an article on all possible ways to create a bootable rescue media.
- Try to disconnect any possible devices from your computer or laptop that are connected to the USB ports.
Did you write the bootable flash drive correctly?
Just copying files on it is not enough. If so, it will not be regarded as bootable. That is why BIOS can not see your flash drive. You have to write it only with special software. There are a lot of them, but I personally use UltraISO. Why? Because it is:
- Free (30 days trial).
- Records both Windows 7 and Windows 8.
- Easy to write images to a 4 GB flash drive (some programs only support USB-drives from 8 GB in size and higher).
And the best part: creating a bootable UltraISO flash drive is easy. First you need to install the program (link to developer’s web-site) and connect the USB-flash drive to your notebook or computer. And after that you only need to perform a few steps:
Start UltraISO and select File-Open in the top menu. After that, you specify the path to the image you want to write. Configure your BIOS correctly
If you have done everything according to the instruction, then be sure. USB-stick is written correctly. And now it is really bootable. Try it. it may be possible to run a Windows installation.
So reboot your notebook or desktop and enter the BIOS. To do this you must repeatedly press a certain button. Usually it is Del or F2, although this may be different (depends on the model of the motherboard and make of the laptop).
If you don’t know which button launches BIOS, take a look here. how to enter BIOS on your PC?
Next, go to the tab with the word “Boot” in its name. This is where you set the boot priority when you turn on your PC or notebook. By default the first (First Boot Device) is the hard disk, then comes the disk drive. You need to put USB HDD in first place and temporarily put the Hard Disk in second place.
