I have converted an ISO and burned it to CD to use as a boot-up disk. However, on rebooting, I am presented with a Command Line interface. The top line reads "Starting Caldera DR-DOS" and the command prompt at the bottom of the screen reads [DR-DOS] A:\> but my computer has no 'A' Drive. It is the 'E' Drive I wish to install the item on. Can anybody guide me? I've never worked with CLI before but there is no GUI alternative offered this time.

It depends upon how the bootable CD is set up.
When you boot into DOS from a CD, the disk is normally emulating a diskette drive, so when the boot sequence exits to a prompt, the CD drive is normally shown as the A: drive.
Another method is to create a RAM drive from the boot CD, which is a virtual drive that is created in the system's memory. In this case, the A: drive is the RAM drive & the CD drive will have a different letter.
Try typing "DIR" followed by enter at the prompt to see the files that should be on the CD are listed. If they're not then it may be using the RAM drive method, so you should try typing "D:" or "E:" etc, followed by enter at the prompt to see if you can find the letter that has been allocated to the CD drive.

Where did you get the ISO? In most bootable CDs, a small portion of the CD functions as a simulated read-only floppy disk. Maybe your CD burning software provides some way to edit the config.sys and autoexec.bat files before burning a CD. In Linux you could mount the floppy image file, but I don't know how you do it in Windows.

Chris is right; CD booting is in fact an emulation of floppy system. Floppy is A: so there you go; the rest of the content on the CD is separate from this booting emulation, go get a DOS book from used discount bookstore; all brands of DOS work and represent itself similar to each other, so if the books are for MS-DOS it is just fine.

the A drive is usually your floppy drive( you 3.5 little black diskette, I know everybody remebers them, but nobdy uses them). you might have to copy the ISO to a floppy in orer to boot from it.
at boot up hold the del. key to get into system set up.
from there change the boot order priority, from A(floppy) to CD,
next make sure that your settings are on auto. your hard drive, cd rom should listed. if you dont have a floppy drive dont know what to tell you.
what you can do, make sure you download file and dont open it. save to desktop. the cd burning program should give you the choice of how to burn cd, make sure that you selelct ISO when you burn it otherwise it wont work

At the command prompt type cd /E or whatever your CD drive letter is

The a: drive it is referring to is what is called a virtual disk. It is where the information is stored in memory and lets you access it directly.
