Do you think are some updates required for https://reactos.org/wiki/LiveUSB article?

Need help with RAM boot to writeable harddrive image

Does the loader use the MBR partition table to find the correct partition? Or do I need to explicitly specify the byte offset from the beginning of the image file using RDIMAGEOFFSET?

When creating the bootable HDD image, do I need to install the bootloader in that image? Or can I skip installing the boot loader in the HDD image, because there's already bootloader in the USB drive's root directory?

Can you post a sample freeldr.ini file with all the needed parameters for this type of boot?

No, you need to specify the offset with /RDIMAGEOFFSET flag (for example, if filesystem in image is offsetted by 32256 bytes, it would be /RDIMAGEOFFSET=32256). IIRC the behaviour is similar in NTLDR.

You are already executing the loader from USB drive, so it is not needed in RAM disk image. As mentioned on the guide you only need put ReactOS system files in the RAM disk image.

It would be similar to the one already in guide for read-only RAM boot. You just need to specify /RDIAMGEOFFSET and /RDPATH , remove /RDEXPORTASCD and optionally /MININT.
