Thanks! Let’s fix this step by step. Since you’re on a Gigabyte G5 KF laptop with InsydeH2O BIOS (version FB10), and you're having trouble accessing advanced BIOS settings, USB boot, and Q-Flash here's how we can unlock the full options and get things working again.
Step-by-Step: Unlock Advanced BIOS + Boot from USB + Q-Flash Access
- Unlock Hidden "Advanced BIOS" on InsydeH2O
InsydeH2O BIOS has hidden advanced settings (like Q-Flash, VMD config, CSM toggle, etc.) that can often be unlocked.
This is unofficial but commonly used and safe if followed exactly.
Here’s how to try it:
Turn on your laptop and immediately press F2 or DEL repeatedly to enter BIOS.
Once inside the BIOS, press this key combo slowly:
bash
Fn + Tab (press 3 times) → then press F10 (save and exit) → then re-enter BIOS
OR (if that doesn’t work):
arduino
Hold Fn + press A
On reboot, go back into BIOS (F2 or DEL) again. You should now see Advanced Mode or new menus like:
Advanced
Chipset
VMD controller
Q-Flash
Let me know if this unlocks more options for you. If it doesn’t, I’ll guide you through BIOS update via bootable USB instead.
- Force Boot from USB (if not showing in Boot Manager)
Even if the USB is properly made, sometimes Secure Boot/VMD settings block it from appearing.
Do this:
Rebuild USB with Rufus:
Partition scheme: GPT
Target system: UEFI (non-CSM)
Use Windows 11 ISO
Try boot menu key: F12
If it still doesn't show, check that:
Secure Boot is Disabled
Fast Boot is Disabled
VMD Controller is Disabled (but only if you are not using RAID SSD config)
- Use Q-Flash to Update BIOS (if needed)
If you can unlock Advanced Mode (see step 1), you should see Q-Flash under the “Save & Exit” tab or in the Advanced tab.
To use it:
Download the latest BIOS for G5 KF (from Gigabyte Support)
Format a USB stick to FAT32
Extract the .bin BIOS file onto the USB
Plug USB into laptop, go into BIOS
Enter Q-Flash and follow prompts to flash the update
Summary of the steps:
Unlock Advanced BIOS > Fn + Tab x3, then F10, re-enter BIOS
Boot from USB > Disable Secure Boot + use F12 Boot Menu
Access Q-Flash > Only shows in Advanced Mode or BIOS “Save & Exit” tab
Reinstall Windows > USB must be GPT + UEFI formatted via Rufus
Hope it will help.
Thanks,
