Install Windows 7 on my "modern" HP laptop

[Коля1]

Sorry to bother you, QUESTION: Is it possible to replace any of the components in my HP laptop? Is it possible to replace the video card, processor or RAM? And is it possible to disassemble my laptop to replace the SSD drive with an old HDD?

The only components you can upgrade is the memory and if your notebook comes with a M.2 NVMe SSD, you can add a 2.5" SATA drive, but the problem is, none of the parts are there to add one.

You will have to find and buy the parts listed in chapter 3 of the service manual to add a 2.5" drive.

How to install Windows 10 in Legacy Support mode (on MBR disk) on HP 245 G9 laptop? Can you send me photos or instructions?

[Paul_Tikkanen]

Does your notebook have a legacy BIOS setting to enable?

If not, you cannot install Windows on the drive with a MBR partition.

If it does, disable secure boot/enable legacy support and then boot your W10 installation media from the legacy USB flash drive, not the UEFI one.

Is it possible to use a third-party utility Paragon Partition Manager to convert GPT to MBR?

[Paul_Tikkanen]

Nope.

The PC will not boot up unless there is a legacy mode option.

UEFI only supports the GPT partition table.

Is it possible to reinstall Windows 10 in MBR mode on the system disk if we convert from GPT to MBR? 

Booting from a flash drive in MBR mode was successful! But I don't know whether it will be possible to install or NOT? That's why I asked you a question!

The PC will not boot up unless there is a legacy mode option if you convert the disk with Windows on it from GPT to MBR.

Hello!

I successfully installed Windows 7 on my HP 245 G9 laptop with an AMD Athlon Silver 3050U processor. The installation process was challenging, but I managed to bypass all restrictions, including USB and NVMe support.

However, I encountered a problem: official drivers for the integrated AMD Radeon (Vega 3) graphics are only available for Windows 10 and 11. Without a proper driver, the system uses a standard VGA adapter, resulting in no hardware acceleration and reduced performance.

Question:
Is there any way to find or patch AMD drivers to work with Windows 7? Maybe someone has experience running similar drivers on older systems? Any help would be greatly appreciated!

Thank you!
