Hi @Sam_26, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
It sounds like your HP G62 might have a corrupted BIOS, and you're running into issues creating the recovery USB. Let's troubleshoot step by step:

Confirm the BIOS Issue

Before proceeding, check if the laptop shows any signs of a failed BIOS:

• Does the Caps Lock or Num Lock LED blink in a specific pattern?
• Does the fan spin at high speed with no display?
• Have you noticed any power cycling (turning on and off repeatedly)?

If so, BIOS recovery is a good option.

Try the Built-in BIOS Recovery First

Many HP laptops have an emergency BIOS recovery feature.

Method: Win + B BIOS Recovery

1. Turn off the laptop.
2. Connect the charger.
3. Hold down Win + B (or Win + V on some models).
4. While holding, press the Power button for a few seconds, then release the power button but keep holding Win + B for another 10 seconds.
5. If the recovery starts, the screen may flash, and you might hear beeping sounds.

If nothing happens, proceed with USB recovery.

Creating a BIOS Recovery USB

If the BIOS is completely corrupted, you'll need to create a recovery USB drive.

Common Issues When Creating the USB

• Error while flashing BIOS to USB: Ensure you are using the correct BIOS file.
• HP BIOS Utility not detecting USB: Try another USB drive (preferably 8GB or smaller).
• "This BIOS is not compatible" error: Confirm you are downloading the correct BIOS for your exact model.

How to Create a BIOS Recovery USB

Download the Correct BIOS

• Go to HP's official support site: HP Support
• Enter your exact model number (e.g., HP G62-XXXX).
• Look for the BIOS version available for your laptop.

Use HP BIOS Recovery Utility

• Download the BIOS update file (.exe).
• Run the BIOS file on another working Windows PC.
• Select "Create Recovery USB" when prompted.
• Insert a FAT32-formatted USB drive (preferably 8GB or less).
• Follow the prompts to create the recovery USB.

Perform USB BIOS Recovery on the Laptop

• Insert the USB drive into the HP G62.
• Turn off the laptop completely.
• Press Win + B and hold it.
• Press Power, then release the Power button while keeping Win + B pressed.
• Wait for the BIOS recovery to start (you may hear beeps or see the screen flicker).

Alternative: Blind Flash the BIOS

If the USB recovery doesn't work:

• Try an older BIOS version (sometimes downgrading works).
• If available, try a BIOS recovery through HP_TOOLS partition (if not deleted).

Last Resort: BIOS Chip Reflash

If the BIOS is completely bricked, you may need:

• A BIOS programmer like CH341A to reflash the chip manually.
• Or take it to a technician for BIOS chip reprogramming.

I hope this helps. 

Take care and have a good day.
