I realize this may or may not be possible but I figured I'd ask. I know that tablets can be used as mass storage devices when plugged in to a PC via USB. I also know that it's quite easy to make a USB thumb drive bootable. What I'd like to know is if there is a way to setup the tablet's storage in a way that will make it bootable if it was plugged in via USB at startup. I'm not asking about booting in to android on a PC, I would have a different os on the volume and use that for PC booting. Yes I could just use a USB drive, but I want to know if this is possible.

DriveDroid allows you to boot your PC from ISO/IMG files stored on your phone. This is ideal for trying Linux distributions or always having a rescue-system on the go... without the need to burn different CDs or USB pendrives. The paid version of DriveDroid does not include ads and helps the developer.

DriveDroid also includes a convenient download menu where you can download USB-images of a number of operating systems from your phone.

You can also create USB-images which allows you to have a blank USB-drive where you can store files in. Another possibility is to use tools on your PC to make a bootable USB-drive out of the blank image that DriveDroid created.

How do you make this work?
* Connect your phone to your PC using an USB cable
* Download an image file (.iso or .img) or create one
* Select the image file in DriveDroid to let your phone 'host' the file over USB
* (Re)start your PC and make sure the correct boot priority is set in the bios
* The image should now be booted on your PC

If u are on custom rom its ok to disable software update. Why don't u use TIBU to freeze those apps?
