[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
Hello.

Here is where I am at in "thinking outside the box".

So instead of trying to flash windows or ubuntu directly onto the nvidia's system partition, why not flash it to a portable drive?

So I am researching UEFI, Bootloaders, flashing, and volumes, particularly how they store and load data.

So I understand that windows requires it's hard disk to be formated to GPT.

My USB stick is MBR. I have a partioning software that can change the USB to GPT.

If anyone understands what I am talking about, can you reach out? I know this is possible, I know the answer is out there,

IT IS JUST ALL THIS JARGON SOME OF YALL USE <3 GOD LOVE YOU ITS HARD TO UNDERSTAND

AND WHAT IM TALKING ABOUT IS DUAL BOOT FOLKS!!! LEGIT DUAL BOOT, NO SECOND PC REQUIRED

AN OS FOR FUN , AND AN OS FOR WORK.....

CAN YOU IMAGINE

""Nvidia uses its own proprietary disk structure on its devices, which look like a modification of GUID partition table(GPT) with protective MBR. Most disk partitioning softwares are unable to read Shield TV's partitions because its primary header is overwritten with non-standard GPT format.

Here are list of disk paritioning software I tried and couldn't even read the disk at all: fdisk, GParted, KDE Partition manager, diskpart and Disk Management on windows. Of course, you may format the disk and rebuild partitions, but then it won't boot from Shield TV at all.

There are two softwares can read partially:

GNOME Disks - the default partition software for Ubuntu, however, could read the partitions IF you boot L4T from Shield TV. It won't work if you try from another computer. Also, it is still unable to modify partitions.

gdisk (GPT fdisk) - gdisk can read partition 2~33 from backup header. As you can see, 33rd partition is the one that holds most of 500GB storage. (462.5 GiB out of 465.66 GiB)""""

A gdisk Walkthrough

What we need to do is GET A NEW BOOTLOADER! Idk how but I will find out! If you know how reach out pl0x

I'm just going to keep dumping knowledge bombs until I or someone elsse figures this out!

How A/B Partitions and Seamless Updates Affect Custom Development on XDA

You may have heard of Seamless Updates before. It involves something called "A/B partitions." What is it and how does it affect custom development on XDA?

system – holds the Android OS, system libraries, system apps, and other system media like bootanimations, stock wallpapers, ringtones, etc.

boot – holds the kernel, ramdisk, and on A/B devices also the recovery as well

recovery – holds the recovery, where TWRP is most commonly flashed on A-only devices (A/B devices don’t have a dedicated recovery partition)

userdata – holds all of your app, system, and internal storage data

vendor – holds platform and device-specific HALs, the files necessary for the Android OS to communicate with the underlying hardware

vbmeta – the partition for Android Verified Boot 2.0 which verifies the integrity of the boot process

gdisk(8) - Linux man page

The gdisk program employs a user interface similar to that of Linux's fdisk, but gdisk modifies GPT partitions. It also has the capability of transforming ...

Going to play with this toy:

GPT fdisk

Download GPT fdisk for free. GPT fdisk is a disk partitioning tool loosely modeled on Linux fdisk, but used for modifying GUID Partition Table (GPT) disks. The related FixParts utility fixes some common problems on Master Boot Record (MBR) disks.

Cause GDISK is for LINUX and I don't like using Linux. No hate but GUI will win over MBR, Mah nerds. Cause GUI IS CMD!! GUI Is Just Easier For Some People! Different Strokes, for Different Folks!

"Upon start, gdisk attempts to identify the partition type in use on the disk. If it finds valid GPT data, gdisk will use it. "

"gdisk" or whatever bootloader you are playing with...

So my only question is how do I make the WIN 11 Arm version bootable... ?? On the USB ?
