[wellylug] LiveCD boot problem after changing DVD drive

[Hong Chyr]

This is the error message from booting the BT2 LiveCD:

[boot messages...]
starting Linux Live scripts <http://www.linux-live.org>
* mounting /proc and /sys filesystems
* creating /dev entries for block devices
* starting loop device support
* starting cdrom filesystem support
* starting squashfs support
* starting aufs support
* starting vfat support
* starting ntfs support
* setup directory for changes
* setup union directory (using aufs)
* looking for data directory
* starting USB support
Fatal error occured - LiveData not found. Searching for BT directory.
You are maybe using an unsupported boot device (eg. SCSI or PCMCIA CD-ROM)
Try to copy the directory BT from CD/USB to your IDE/SATA harddisk,
for example to /mnt/sda1 in Linux or C:\ in Windos. Then boot again.
* Something went wrong and we can't continue. This should never happen.
* Please reboot your computer with Ctrl-Alt-Delete ...
/ #
[boot process stops here, with a command prompt]

Its interesting to note that the error messages are the same for both 
physically booting the CD and booting the CD from VMware, except for the 
mapping of device; DVD drive is /dev/hda in physical boot, /dev/hdc in 
VMware.

Booting the ISO file in VMware is fine. It completed the boot process 
without any problems. In this case, HDD is /dev/hda and DVD drive is 
/dev/hdc.

I don't think there is any change in the device mapping from old DVD 
drive to new drive. The failed LiveCD can detect the DVD drive as 
/dev/hda and local HDD as /dev/sda. Can't see what has changed to make 
the CDs not booting, especially when it doesn't seem to have anything to 
do with physically reading the discs and the kernel is detecting all 
devices and mapping to the same device files...
