Installing linux from an ISO file to your system disk
If you are installing linux from E2B in MBR-mode and booting from the ISO, the install script or GUI may fail to find the 'cdrom'.
A typical set of questions with responses to avoid this problem would be:
Load CD-Rom drivers from removable media - No
Manually select a CD-Rom driver - Yes
Module needed for accessing cd-rom - none
Load CD-Rom drivers from removable media - No
Manually select a CD-Rom driver - Yes
Module needed for accessing CD-Rom - none
You will then be asked to enter the Device file for accessing the CD-ROM...
At this point, you should enter the location that E2B has mapped the ISO to (partition 4), so type:
/dev/sdX4 (where X is the device letter, so use /dev/sdb4 if the USB drive is the 2nd drive in the system)
If this does not work, try -t iso9660 /dev/sdX4.
Tip: run a console and type sudo fdisk -l or lsblk -f or parted -l or df -h or ls /dev/sd* to determine the device name of the E2B USB drive.
Installing linux from a .imgPTN file
The linux files will usually be on the first partition of the USB drive if a FAT32 .imgPTN is used, so use:
-t vfat /dev/sdX1 (where X is the device letter, so use /dev/sdc1 if the USB drive is the 3rd drive in the system).
If you have used two partition images (a xxxxx.imgPTN + xxxxx. files), then the source files may be located on the 3rd partition, so use -t vfat /dev/sdX3
Tip: run a console and type sudo fdisk -l or lsblk -f or parted -l or df -h or ls /dev/sd* to determine the device name of the E2B USB drive.
