I recently ran into a weird hardware quirk. I create a bootable USB stick that was working perfectly on every Dell laptop. But the second I plugged it into an HP 240 G8? Silence. The BIOS acted like nothing was even plugged in. After some digging, I realized that what works for one brand’s ecosystem doesn’t always translate to another.
Check USB Boot option is enabled or disabled. Go to BIOS by pressing F10
- Enable the USB Boot
- Disable Secure Boot
- Change the UEFI Boot Order by Pressing F5 and F6 to toggle the boot order.
- Make Sure in the first boot to be USB Flash Drive / USB Hard Disk
- Press F10 and save settings
- Shutdown the computer
Plugin in the USB Stick and Turn on the HP 240 G8 Laptop and keep pressing F9 to see the boot menu. If you do not see USB Stick Is Not Being Recognized as a Bootable Device, Even after enabling the setting correctly in BIOS. What could gone wrong in recognizing the USB Stick?
I talk to HP technical team, they could not solve the problem and kept trying to resolve in various method and various brands of USB Sticks but still the result was same.
I spent a day in finding the solution nothing was working and there was no much options left and was thinking of giving up the issue. But still mind was not accepting and next day i try to think different from the beginning.
USB stick comes in two version 2.0 and 3.0, the disk which i was trying to boot was USB 2.0. Now what did is to create a USB Bootable disk on USB Stick 3.0. To my surprise USB Stick Recognized as a Bootable Device, able to boot Window 10 OS.
If your computer does not recognize the USB Stick, check the USB Version 2.0 or 3.0 that should fix the problem.
In HP 240 G8 laptop, the storage device is not recognized and need to install intel storage controllers drivers manually. Go to HP site and download Intel Rapid Storage Technology Driver.
Difference Between USB2.0 and USB 3.0
| USB 2.0, which operates in half-duplex mode | USB 3.0 supports full-duplex communication. |
| USB 2.0 has a maximum speed of 480 Mbps | USB 3.0 has maximum data transfer rate of 5 Gbps |
| USB 2.0 devices consume More Power | USB 3.0 devices consume less power |
Q1. Why is my bootable USB not detected?
A: The issue can be caused by incorrect boot mode (UEFI/Legacy), improper USB formatting, or BIOS settings.
Q2. Should I use MBR or GPT for bootable USB?
A: It depends on your system’s BIOS mode. Legacy BIOS requires MBR, while UEFI works with GPT.
