@Stepanek, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
Based on what you're experiencing, here are a few steps you can take to troubleshoot your HP 15-wb0xx laptop after installing the new RAM:

Remove New RAM & Boot

• Remove the newly installed 4GB RAM.
• Boot with only the original RAM.
• If it boots successfully, the new RAM is likely the issue.

Test New RAM Alone

• Remove the original RAM.
• Insert only the new stick.
• Try to boot.
  • If it doesn’t boot, the stick is likely bad or not compatible with your laptop.
  • If it does boot, it may be a dual-channel conflict.

Check RAM Seating

• When installing, ensure the RAM clicks in firmly.
• Gently press down until it locks on both sides.

Clear CMOS (Reset BIOS)

Since your BIOS settings won’t save and it’s stuck in a boot loop:

1. Disconnect the AC adapter and remove the battery (if removable).
2. Hold the power button for 20-30 seconds to drain residual charge.
3. Then power it back on with only one RAM stick installed.
4. If your model has a CMOS battery or reset pin (some HP models do), you might need to short the CMOS reset pins or remove the battery to reset BIOS completely.

Try Matching Brands or Specs Closer

If you suspect it's a compatibility issue:

• Try getting the same brand, timings, and voltage as your existing RAM.
• Alternatively, use two identical sticks if you can afford it.

Still Not Booting?

If no RAM configuration works anymore (even with just the original), the BIOS might’ve glitched from the failed boots. You can try:

• Disconnecting all power,
• Resetting CMOS,
• Booting with original RAM only,
• Or even using the Win + B or Win + V BIOS recovery keys when powering on (HP has a recovery feature like that).

I hope this helps. 

Take care and have a good day.

Both rams works So IT will ne dual channel conflict. The thing im most worried about now Is the fact that i can't save bios settings. i dont have OS installed And i want to install Linux. Like 1hour Before the linux i installed Windows 11but it was laggy so i decided to uninstall it. I tried everything even changed bios battery but still cant save Is there like cmd command that can disable Safe boot or something like that. I need to get that PC going as soon as possible. Any suggestions?

@Stepanek, thanks for confirming both RAM sticks work individually.

Your BIOS/UEFI settings are saved in a small storage chip (NVRAM). If that chip is corrupted, BIOS settings won’t persist — even after battery replacement. This explains why:

• BIOS resets every time.
• Secure Boot stays on.
• Boot order can’t be changed.
• Linux installer can’t boot (likely due to Secure Boot being enabled and UEFI settings not changing).

Try These Solutions

Hard Reset BIOS via Recovery Key

Let’s trigger HP’s built-in UEFI recovery.

Steps:

1. Shut down the laptop completely.
2. Plug in power adapter.
3. Press and hold Win + V or Win + B, then press the power button.
4. Keep holding Win + V/B for 10-15 seconds.
5. You should hear beeps or see an HP BIOS recovery screen.

If you see the recovery menu, choose "Reset to factory defaults" or "Reset NVRAM".

Use Only One RAM Stick Temporarily

For now, remove one RAM stick to avoid dual-channel instability during setup. This can sometimes interfere with BIOS or boot behavior.

Create a Bootable Linux USB with Legacy+UEFI Support

Some HP laptops with broken BIOS save issues still boot into UEFI media if it's built properly.

Recommended tool:

• Use Rufus (on another PC) to create a bootable USB for Linux.
• Select the option:
  • GPT partition scheme for UEFI, OR
  • MBR + UEFI (non-CSM) for better compatibility.
• Disable Secure Boot option in Rufus (if possible).
• Write ISO in DD mode, not ISO mode.

Try booting from this USB even if you can’t change boot order. Press Esc repeatedly when powering on, then F9 for Boot Menu, and manually choose USB.

Use HP’s biosconfigutility.exe (if you get OS installed)

Once Linux is up, you could boot into Windows PE or temporary install just to use:

biosconfigutility.exe /SetConfig:settings.txt

This tool lets you force change BIOS settings via command line, but it runs only under Windows or WinPE.

Final Option: Flash BIOS

If BIOS won't save settings and recovery fails:

• Download the latest BIOS from HP’s support page for your exact model.
• Create a USB BIOS recovery drive using HP’s BIOS installer.
• Insert it, then use Win + B at startup again.

This might reflash and repair NVRAM corruption.

I hope this helps!
