戰神電腦無法辨識 USB 啟動，令許多使用者感到困擾。此問題可能由各種因素引起，包括 BIOS 設定、U 碟故障以及硬體相容性問題。 php小編魚仔將深入探討導致此問題的原因並提供逐步指南，以幫助您解決此問題。請繼續閱讀以下內容，以獲取有關如何修復戰神電腦無法識別 USB 啟動的寶貴見解。
1.不同電腦電腦啟動熱鍵不一樣,大部分是F12,有的則是F11、Esc、F7等;
2.如果確定電腦啟動熱鍵是F12,那麼可能需要按Fn+F12
3.還有一種可能,是BIOS禁用了F12快捷鍵,這時候進BIOS開啟即可;
4.最後一種就是老舊機型,只能BIOS設定,不能透過快捷鍵選擇U盤啟動
此方法並不適用於所有電腦！ ！ ！ ！ ！純屬應急！ ！請謹慎使用！ ！ ！我也搜過相關的問題，但實在搞不懂bios是個什麼東西，而且什麼開機按F2或DEL鍵進行修改都試過，但電腦沒有任何反應。首先，打開
“設備與印表機”，就在控制面板裡打開，如果你的任務欄也有顯示就右鍵單擊圖標就可以打開。
在設備這一欄找到你使用的u盤。右鍵點選你的u盤，點選刪除裝置。
在這裡我不太清楚是應該先拔出u盤再刪除還是先刪除，因為你的u盤常用的話，你的電腦已經自動記憶了，所以拔出其實這個圖標也還留著，所以要考慮這個問題。反正我是先刪除，顧不得其他了。 。但一定要注意一定要在你的u盤沒有文件運行的時候這樣做，否則會燒壞u盤的。隔幾秒鐘再插上你就會發現一切恢復了，現在我真是喜出望外呢～(￣▽￣～)(～￣▽￣)～當電腦無法讀取U盤時，首先需要確認U盤本身是否正常。可以將U盤插入其他電腦或設備，看是否能夠被正常辨識。如果其他設備也無法讀取，有可能是U盤本身出現了問題。
有時候，電腦的USB介面可能故障，導致無法辨識U盤。可以嘗試將U盤插入電腦的其他USB接口，以確認是不是接口的問題。
在Windows系統中，可以進入裝置管理員來查看U碟的狀態。如果在裝置管理員中能夠找到U盤，且沒有黃色感嘆號或紅色叉標誌，那可能是USB隨身碟的驅動程式出現了問題。
如果發現U碟驅動程式出現了問題，可以嘗試更新驅動程式。可以透過裝置管理員中的自動更新，或是到U盤廠商的官方網站下載最新的驅動程式進行安裝。
有時候，U盤中的病毒或檔案系統出現問題也會導致電腦無法讀取U盤。可以使用防毒軟體掃描U盤，或在電腦中對U盤進行錯誤檢查與修復。
如果在某台電腦無法讀取U盤，可以嘗試在其他電腦上或使用不同的作業系統來查看U盤的狀況。如果其他設備或系統可以識別，可能是目前電腦系統的問題。
在排查電腦無法辨識U盤的問題時，以上步驟可以幫助使用者初步確認故障點，從而採取相應的解決措施。若以上方法均未解決問題，建議聯絡專業人士進行進一步的檢查與修復。
感謝您閱讀本文，希望能幫助您排查電腦無法辨識U盤的問題，確保資料安全和設備正常使用。
可能是U盤損壞或系統原因。依下列步驟，一步步排除故障。
1、在確保沒問題的USB介面上，插上U盤，聽一下音箱有沒有叮咚一聲的響聲。如果什麼聲音也沒有，表示電腦完全沒有辨識到有USB設備插入，那可能是U盤壞了。
2、如果有聲音，表示能偵測到USB設備，可能是系統的問題導致沒辨識。依下列方法操作即可：
1)右鍵點計算機，屬性，裝置管理員，磁碟管理器。
2）如有黃色嘆號的設備，右鍵點它把它卸載掉。
3）如果有標著向下黑色箭頭的磁碟，那就是被禁用了，就右鍵點擊，啟動它。然後刷新或重新啟動電腦，一般就找到了。
4) If there is no problem in the device manager, it means that the drive letter is not automatically assigned. Right click on Computer (or My Computer), Manage, Disk Management. Find the disk partition you want to change, right-click it, select "Change drive letter and path", then select "Add" and assign a drive letter.
If it doesn’t work, then the USB flash drive is broken, or the system-related functions are damaged. You can judge by trying it on someone else's computer.

The problem that the USB flash drive cannot be recognized is a problem we often encounter. For USB flash drives, which are mobile storage devices used in our daily work, sometimes we store some temporary important files. If the USB flash drive is inserted at this time If the computer cannot recognize it, it will cause some problems. In order to avoid such things from happening, below we will teach you three solutions to the problem that the USB disk cannot be recognized.
1. When the USB flash drive is inserted into the computer, there will be a sound prompt from the system and a yellow question mark on the taskbar:
This situation indicates that the USB flash drive is not broken. There should be a problem with the driver, which can be solved by reinstalling or updating.
2. When the USB flash drive is inserted into the computer, there is a sound prompt from the system, but the USB drive letter cannot be found in the computer:
3. There is no response when the USB flash drive is inserted into the computer:
This problem may be that the USB root hub is disabled, here You can refer to "What should I do if the win7 system cannot recognize the USB device?" and set the disabled to enabled.
The solution to the problem that the USB disk cannot be recognized is introduced here. In the actual process, we should not rush to judge whether the USB disk is broken. We should first change a few more jacks and test on several more computers, otherwise we will misjudge. And discard the USB disk that can be used normally.
The solution and steps are as follows:
1. There is a symbol prompt on the external USB disk connection, but it cannot be seen in the computer drive letter and the USB disk management on the desktop.
2. First click the win icon on the taskbar, then click "Settings" (or directly use the shortcut key win+i) to enter the "Settings Interface" under win10.
3. Then enter the "Device" management interface.
4. Click on the connected device, and then the computer's external device will appear in the list on the left. Here you can see that the USB flash drive device that has been plugged in appears here.
5. Click and the "Delete Device" click item will appear, and then click "Delete Device". The USB drive will be removed. After that, unplug the USB flash drive and plug it in again, and the drive letter will appear on the computer.
Note: Applicable to win10 interface, only when the USB disk is connected to the computer, but the drive letter is not displayed.
