If you need any additional information, I am ready to provide it. BIOS dump in the attachment.

In your dump is no advanced menu. Whitelist removal possible, but not easy without bricking or test machine.
   

The easiest way to get your internal wlan running without modding software & having the issue that Windows 10 and upwards does not properly support the bluetooth stack minipci-e cards anymore since they are really old by now. The drivers are all emulating the stack (universal driver) and it works but the performance is bad audio sink profile for example bitrate is so bad trust me not worth the effort. I've tested 20+ cards. If I recall Realtek worked the best out of the box, Broadcom the worst Intel was a mess driver wise but still not worth all the effort. I ended up either getting the minipci-e to m.2 riser card, it only supports A+E key M.2 NGFF and has IPEX 4 antennas that are the smaller size compared to your old mini pci-e wlan cards IPEX 1 antenna connection. But if you are willing to you can add 2.4g and 5ghz wlan + a proper working bluetooth stack I have tested it and it works great you just need to mod some stuff in your laptop case but since yours has a whitelist kinda unrelevant. Why not look at the serial bus in the mini pci-e slot? The bandwidth of the bus is theoretically good enough for a maximum of 240-320 Mbps network speed.

pin 36 USB_D-
pin 38 USB_D+
pin 50 GND
pin 52 +3.3V

You have also mini pci-e to usb riser cards that break out a female port so you can put in a small USB wlan adaper in it.
No firmware modifications needed and the adapter is inside the laptop.

You wrong.
Advanced menu is there, but hidden. I have modded this type of bios many times, so I know for sure.

Whitelist disabled mod is available on the forum since 2012.

Thanks for clearing that up, you seem to have played more with Phoenix bios than me.
I do know about the whitelist mods being available on here. But one still needs to modify the firmware.

Maxinator500, NiTrOwow
The BIOS dump was made with a BIOS mod (Whitelist Removal, WMX/VT-x unlocked, ....). From this one: [https://www.bios-mods.com/forum/showthread.php?tid=16189&pid=200646#pid200646].
If necessary, I will install the BIOS from the Lenovo website [https://download.lenovo.com/UserFiles/Dr...O06WW6.exe] and make a dump!?

Hello. Is there a BIOS mod that takes the GT-240M graphics card into account? New drivers 341.92 (that is, only 258.96, 260.99, 267.76) are not installed. Nvidia drivers are not installed, and there is no access to the integrated video card Intel Graphics Media Accelerator 4500MHD (Intel GMA 4500MHD). The Advanced tab is missing in the BIOS.

Additionally. The solution for fixing the BIOS bug for the Lenovo Y550 in Linux is available at the links below.

https://forum.ubuntu.ru/index.php?topic=291203.0
https://forums.developer.nvidia.com/t/lenovo-y550-...

So, it's definitely a BUG.

All that's left is to "read" the Linux solution and, following the example, accurately transfer it to Windows 7, 10, and/or simply modify the BIOS. Anyone who knows how to do this? Thank you!

While the great gurus are gathering their thoughts, I am ready to test Linux (linuxmint-20.3-xfce-64bit). Which PPA should I use, or what AI tool can help me write the installation and startup script?
Please consider the setup process and correct execution order for both HDD and SSD configurations (since SSDs boot much faster, the script might require a time delay like sleep to ensure proper initialization order).
