im trying to recover my Vista laptop i set it to boot from the disk, it does, flash screen comes up then a bunch of lines load through. It then get to "Trying to unpack rootfs image as initramfs" and a line of dots come up, then it just stalls out.
Depending on how slow your PC is, that can take a long time to complete. You can tell if it's working or not based on whether new dots are added to that line or if stays the same.
