yes, as mentioned, this is a recovery method of installing, you need a working wifi or lan so the installer can access the internet to download the operating system during installation :)

I understand now.

<<We will be using Windows for this tutorial, only the recovery will be installed to the USB stick, this means that when you boot to the installation, it will require internet access to be able to download and install macOS>>

I got macOS Catalina 10.15.7 (openCore) installed on my T440p. But still I need boot from USB.
How can I boot from new Catalina? In past we must install clover on laptop. How can I do it with openCore?

Thanks

you would just copy the EFI folder into the EFI partition on your usb or hard drive

I'm confused .... This are steps I have followed to install Catalina, and upgrade to Big Sur on my T440p. Only this

You will be wanting to change:
AAPL,ig-platform-id
device-id
model

Read post 2 for configurations

Haswell
Device Properties - Add - PciRoot(0x0)/Pci(0x2,0x0)
AAPL,ig-platform-id -> 0500260A (for HD5000, HD5100 and HD5200)
AAPL,ig-platform-id -> 0600260A (for HD4200, HD4400 and HD4600)
device-id -> 12040000 (for HD4200, HD4400 and HD4600 ONLY)

kernel - quirks:
enable:
DisableIoMapper
PanicNoKextDump
PowerTimeoutKernelPanic

SystemProductName:
MacBookPro11,1

UEFI -> Quirks:
enable:
IgnoreInvalidFlexRatio
ReleaseUsbOwnership

Nothing about this

Despite this guide is in Big Sur Section, I highly recommend at this time to install Catalina so you can perform proper USB discovery using this guide:
after installation, reason being is that XhciPortLimit is broken in Big Sur and Monterey and is required for USB port discovery.

I just have used your EFI folder ....


Once you have Catalina installed and the above USBPorts.kext correctly configured, then you can update to latest OpenCore and kexts and then upgrade to Big Sur or Monterey

How can I update to last OpenCore and kexts? I need audio etc

PD: Now looking on help-me-understand-how-to-upgrade-opencore
