Abstract

A computerized user interface for assisting a computer user selects a default operating system for a computer. The computerized interface operates during a current computing session and provides a list of operating systems available. A user can make a selection using standard activatible controls such as icons, alphanumeric lists and highlighting. Once selected, an operating becomes the default operating system software on the computer. Therefore, during the next startup of the computer a selected operating system will boot unless there is some other intervention. In addition to selecting an operating system, this invention can also be used to cause the computer to restart. Restart can be set to execute immediately or to execute upon a change in the default operating system. In addition this invention can be caused to uninstall thereby erasing the program files relating to this invention.

Claims

1. A system for assisting a user in selecting an operating system for use on an electronic device, said system comprising:

an electronic device configured to store, display, and process information under a selectable one of a plurality of operating systems; and

program code running on said electronic device with a current operating system, the program code configured to determine one or more alternative operating systems available for subsequent boot processes, the program code further comprising;

a control mechanism for choosing a selected alternative operating system for the next boot process wherein the selected alternative operating system is one of the plurality of alternative operating systems available for subsequent boot processes;

an operating system indicator stored on said electronic device, wherein the operating system indicator identifies the selected alternative; and

a time out period setting that determines a time out period occurring during the boot sequence of the selected alternative operating system, the time out period varying based on the selected alternative operating system;

wherein the program code is configured to automatically close any open applications in response to the selection of the future operating system and wherein the program code is further configured to automatically induce the electronic device to reboot for operation under the selected alternative operating system, and

wherein, if during the next boot process, the time out period expires without the selection of a different operating system, the program code boots the selected alternative operating system identified by the operating system indicator.

2. The system of claim 1, wherein the program code further implements a mechanism to allow a user to set a duration of time comprising a time out period during which a load utility pauses and allows a user to specify an operating system other than a default operating system.

3. The system of claim 1, wherein a change of a default operating system causes a file containing settings for a boot menu to be modified wherein the file specifies the operating system selected.

4. The system of claim 1, wherein the program code additionally comprises a mechanism for uninstalling the program code.

5. The system of claim 1, wherein the program code additionally comprises a mechanism for reinstalling the program code.

6. The system of claim 1, wherein an installation routine for installing the program code surveys the electronic device and determines the presence of operating systems available on said electronic device and the partition on which the operating system resides.

7. A method of launching an operating system of choice, comprising:

determining alternative operating systems that are available for a subsequent boot process and on which disk partition each alternative operating system is stored;

displaying a graphical user interface on a display, said display listing a plurality of the alternative operating systems for the next boot process;

providing a selection mechanism for selecting an alternative operating system of choice;

in the event the selected alternative operating system differs from a previously selected operating system, changing a time out period that occurs during the boot sequence of the selected alternative operating system;

setting the selected alternative operating system as the default operating system for a load utility installed on an electronic device;

automatically closing any open applications when the selected alternative operating system differs from a previously selected operating system;

inducing a restart of the electronic device when the selected alternative operating system differs from a previously selected operating system; and

automatically booting the selective alternative operating system, if the time out period expires during without the selection of a different operating system.

8. The method of claim 7, further comprising allowing a user to set the duration of the time out period.

9. The method of claim 7, further comprising restarting the electronic device in response to an input made via an input device calling for the electronic device to restart.

10. The method of claim 7, further comprising providing a mechanism for uninstalling program code that performs displaying, providing, selecting, and setting.

11. The method of claim 7, further comprising providing a mechanism for reinstalling program code that performs the steps of displaying, providing, selecting, and setting.

12. The method of claim 7, further comprising surveying the electronic device and determining the presence of operating systems available on said electronic device and the partition on which the operating system resides.

13. A graphical user interface for an electronic device displayed by a boot selection program for selecting an operating system, said graphical user interface comprising:

a first display region of a graphical user interface listing a plurality of available operating systems stored on a user rewriteable storage media of the electronic device wherein the listing of the plurality of alternative operating systems for subsequent boot processes is determined by surveying where each alternative operating system is stored; and

a second display region of the graphical user interface including a user activatible control to select one of the alternative operating systems, wherein a time out period is changed if the selected alternative operating system differs from a previously selected operating system, wherein open applications are automatically closed and the selected alternative operating system is automatically loaded by the electronic device when the selected alternative operating system differs from a previously selected operating system, and wherein the selected alternative operating system is automatically loaded during the boot process when the time out period expires without the selection of a different operating system.

14. The user interface of claim 13, further comprising a third display region for initiating a command to restart the electronic device, said third region including user activatible controls to specify when the electronic device restarts.

15. The user interface of claim 13, wherein the interface is displayed upon clicking an icon of a boot.
