Indeed.

Suppose vmlinuz, initrd.gz, grub.cfg and the ISO are on a USB stick. The
stick can be booted and the installation done to a hard drive, which I
would guess is common place to put it. This avoids having to consider
the memory situation or mess with the installation afterwards.

Those users who cannot boot from a USB stick can have vmlinuz, initrd.gz
and grub.cfg on the hard disk and the ISO on a USB stick, where it should
found.
