There is a diagram here, which helps explain the boot menu.
There really should only be one Macrium item, not two, to my
way of thinking.

One question would be, if the BCD is ever rebuilt, will all
those optional materials end up in the BCD again. That I don't
know. The Macrium CD, for example, if you select boot repair,
it does not particularly preserve the structure of the existing
BCD when it builds a new one. It just does a scan, detects the
things it "sees" and adds them.

The Macrium CD should always work. Any other items with the
word "Macrium" in them, will work as long as the storage they
sit on, is not corrupted.

There is no particular performance difference. If a WinRE or
a WinPE boots, the contents are stored in RAM (drive X: ),
and all materials run at RAM speed. The largest item designed
this way so far, is a "Hirens" disc, which stores several gigabytes
in RAM (and then, the machines running such a disc, need at least
that much RAM for the boot to finish).

If you didn't have your CD, you could use a menu item like that,
but it's unclear what issues might arise. Since the OS and X: are
in RAM, you should (in theory) be able to *overwrite* the disk
drive the thing booted from. How kooky is that ? Well, maybe for
once they did a good thing. If the Macrium Restore went half way
and stopped while doing that, you could very well be screwed
(then you'd need the CD to finish the job).
