1. An electronic device having an alterable configuration, comprising:
- a non-volatile memory configurable to include at least a first partition and a second partition, the non-volatile memory storing a boot ROM that is operable when said boot ROM is executed by a processor of said electronic device to;
in the event that a third partition is available, boot an operating system in the third partition, the operating system operable when booted to cause the third partition to be deleted and the second partition to be expanded to encompass memory freed by the deletion; and
otherwiseboot an operating system in the first partition.

Abstract
An electronic device having an alterable configuration includes a non-volatile memory configurable to include at least a first partition and a second partition, the non-volatile memory storing a boot ROM. The boot ROM is operable when executed by a processor of said electronic device to, in the event that a third partition is available, boot an operating system in the third partition, the operating system operable when booted to cause the third partition to be deleted and the second partition to be expanded to encompass memory freed by the deletion; and otherwise boot an operating system in the first partition.

6. A method of manufacturing an electronic device, comprising:
-
assembling said electronic device using a non-volatile memory to include at least a first partition, a second partition, a third partition and a boot ROM; causing the boot ROM to execute a first operating system stored in the first partition, in volatile memory; deleting the first partition; and expanding the third partition to encompass non-volatile memory freed by the deleting, wherein said boot ROM is operable to execute a second operating system stored in the second partition when the first operating system is no longer available in the non-volatile memory. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method of configuring an electronic device having non-volatile memory with a first partition and a second partition, comprising:
-
causing the electronic device to execute a downloader application, wherein the downloader application is operable when executed by a processor on the electronic device to download an installer operating system and reduce the second partition to accommodate an installer operating system partition; storing the installer operating system in the installer operating system partition; causing the electronic device to boot the installer operating system, wherein the installer operating system is operable when booted to overwrite an operating system in the first partition with a replacement operating system, delete the installer operating system partition, and expand the second partition to encompass non-volatile memory freed by the deletion; and causing the electronic device to boot the replacement operating system. - View Dependent Claims (14, 15, 16)

17. A method of configuring an electronic device, comprising:
-
assembling said electronic device using a non-volatile memory to include at least a first operating system in a first partition, a second operating system in a second partition, a file system in a third partition, and a boot ROM; executing the boot ROM a first time, the boot ROM booting the first operating system into volatile memory, the first operating system deleting the first partition and expanding the third partition to encompass non-volatile memory freed by the deleting; executing the boot ROM a second time, the boot ROM in response to determining that the first operating system is no longer available due to the deleting automatically booting the second operating system into volatile memory. - View Dependent Claims (18, 19, 20)
