Boot gave up waiting for root device
Have just tried to load Linux Ubuntu from USB stick using Unetbootin. Window was already loaded on 1st disk I tried(2tb) All seemed to go with the load until the reboot. Grub screen was displayed and the default ubuntu selected. Then message gave up waiting for root device. Am trying using a completely blank disk with a new download to new USB stick.

If you are trying to boot your machine from a usb drive with ubuntu on it, then it will need the initramfs which supplies the root device to the kernel. There may be a corruption in the iso image burned to your usb disk. Try re-burning the iso image and make sure you are using a good iso image before you burn.
