Hi Thomas, > Anyways, 32 GB of size should not be a problem.
Ok. size does not matter > > > When the stick is booting, first appear the usual text messages, > The first message is the boot prompt. Then the usual messages· PCI found and so on. Last message is, that a new USB device is found, then the screen goes blank. I can make some snapshots of a video, by interest. > Can you determine the origin of the last visible messages ? Yes, see above. > BIOS/EFI ? The BIOS is without EFI. > Boot loader (GRUB or ISOLINUX/SYSLINUX) ? Bootloader is grub, the image is an image from kali linux. The big size comes from a virtualbox image inside for windows 10. (the vmdk is smaller than 4GB, so bootcdwrite got not into problems). > Linux ? Yes, KALI Linux, which is Debian based. > Debian installation software ? vers close to. > > Is Virtualbox using the same BIOS type as the real machine ? > I mean EFI versus Legacy BIOS aka CSM mode. > Yes, it uses legacy bios. > > Is the USB stick large enough for the image ? Yes, it is. The image is about 32 GB big, the USB-stick is 64GB. Should fit very well. The last ISO working was baout 12GB and fit on a 32GB stick. > > Can dd read the whole image back from the USB stick ? > Yes, it can.
