Hi,

I just downloaded the Ubuntu 10.10 appliance to try out on a bootable USB stick formatted in ntfs. I'd already installed vboot on it, from Windows, and tested it by booting a BartPE ISO that it also contained, which worked fine.

I unzipped the Ubuntu archive onto the USB stick in its ubuntu-1010 subdirectory, and added the following to its grub.cfg from the readme.html file:

menuentry "VHD Ubuntu, Linux 2.6.35-28-generic" {
insmod vhd
vhd vhd0 (hd0,1)/ubuntu-1010/ubuntu-1010-desktop-i386.vhd --partitions
linux (vhd0,1)/boot/vmlinuz-2.6.35-28-generic root=/dev/sda1 vloop=/ubuntu-1010/ubuntu-1010-desktop-i386.vhd vlooppart=p1 quiet splash
initrd (vhd0,1)/boot/initrd.img-2.6.35-28-generic
}

But it wont boot, it shows the following error:



I also tried:

menuentry "Ubuntu" {
vboot harddisk="(hd0,1)/ubuntu-1010/ubuntu-1010-desktop-i386.vhd"
}

But that didn't work either.

Am I doing something stupidly wrong??

For USB boot, you need to change root=/dev/sda1 to root=/dev/sdb1, it's confusing, at boot time, it's hd0, but after boot, USB becomes 2nd disk (the 3rd if you have 2 disks), the real hard disk is first disk.
