NAND is basically the flash memory chip stored on your phones board, ie where the standard native OS is stored and booted from.
You can boot Android from NAND or SD, whereas WP7 needs to be booted from NAND.

Thank you for that
So basically I have flashed my NAND when I updated from WM6.5 to WP7 correct?

Yes.
Sorry under 8 posts I can't post links, so go to Wikipedia -> Flash Memory -> NAND-Flash for a detailed technical description.

Yes, Your OS is stored and booted from NAND. Only time it isnt is in the SD builds, In these cases its stored on your SD card and you use your windows mobile to boot a program which in turn reboots your phone into a different kernel.

[Q] WINMO 6.5 on NAND and MAGLDR running Android of SD

Hi all
Since Magldr is out,
I used to think this was possible
WINMO on NAND + MAGLDR running android from SD
So if i wanted winmo i just boot straight into my phone if i want android choose it from MAGLDR and boot straight into it
Am i missing something ...

Actually yeah I thought I remember somewhere you could still use windows on nand and android on sd, or android on nand and sd.

EXACTLY ...
its on the wiki page :O
Yeah you're missing something alright.
the MAGLDR enables the ability to load Android from the NAND instead, wiping out WinMo.

yes i know that very well,,,
did you happen to read this
http://htc-linux.org/wiki/index.php?title=Leo/Magldr
may be cotulla can shed light on this
Keeping WinMo and Having direct boot of Android of sdcard sounds good to me. I read in gauners and cotullas builds that sdcard was faster for reads/writes than nand? Did I read that right?
Also, can anyone answer why you can't have both Android and Winmo on Nand dual booting? I am sure there are good reasons, I just don't know what they are? Is it like in a hard drive where you have the 'active' partition?

I am perfectly happy with MAGLDR the way it is now,,,
But i was under the impression that WIN mo could be in NAND and Android of SD with MAGLDR we can directly boot android of SD

Yes, I read that on the wiki that was linked above. I like booting Android off sd, but what has me concerned is people a few people saying that sdcards can only handle about 1000writes per block before they go bad. Not a big deal, but someone also wisely said that 'electronics die at the worst time.'
I would really like to know if this is possible
RUN ANDROID, WP7, AND REG WINMO 6.5 on NAND???????
or at least have some way off keeping WINMO 6.5 while being able to use WP7 AND ANDROID
please no has yet to answer this!

[Q] Do SD Builds boot using MAGLDR?

Ok so there are obvious NAND builds which I can flash as per WM ROMS, they will boot fine, but can I put an SD build on my sd card and it boot direct from MAGLDR?
I know it supports booting android from SD but which builds? Also do the files have to be in a different location that sd\Android?
Thanks we could really do with a MAGLDR 101 type sticky
Thanks in advance
Please move to Android Q&A I've just had a senior moment! :-(

It is now possible to boot most roms that haret.exe ran using magldr

you will need some linux skills to do it as it involves mounting an image and changing one line in init.rc

WP7 & Android

How can we start dual boot with wp7 or can we do 2 partition with MAGLDR 1.12 and boot to WP7 or Android is it possible?

Atheist,
could you point me to the link bro, there is too much stuff about wp7 since the past 2 days,
I am under the impression that we cant have WP7 and Android on NAND at this point in time ,
Open to corrections,
Well you cant have both on nand, well not atm and especially not a LEO512 but you can run Android via SD card while WP7 is on phone.
There has been various guides posted in SD forum...
[REF] How to boot your SD build from magldr [quick guide]
[REF] Tutorial: How to partition sd card to run wp7 and android from same sd card
I think there is a few more aswell but these are the ones stickied in the SD card forum. I haven't personally tried these yet but will be soon.
oh wow, i'm gonna try that, wish there was a partition manager in magldr that will allow nand booting of WP7 and Android, i have LEO1024

Dual Boot Possible with NAND ROMS?

I haven't bothered installing the MAGLDR yet because I am very comfortable with my setup, I have windows mobile 6.5 with android SD, however would it be possible to dual boot Windows Phone 7 with android or Windows Mobile 6.5 on the Nand? Like for the TMOUS1024 devices? I've read on the chinese site for the DFT that its possible but the instructions are very hard to understand. I can't be the only one wondering this or wanting this? Any ideas guys?
I too would love the ability to dual boot, whether it be dual-nand, or WP7 as an SD build (and Android NAND).
Any chance of this happening, devs?
Right now u can dual boot Android NAND and Android SD.
Windows 7 NAND and Android SD but this is too complex. u need to make two partitions on the SD card.
I too would like to still run wm 6.5 as my main os and boot WM7 and Android from my Sd cards. I would also like to know if this is possible.
Is it possible to boot a SD android version via magldr?
Mine freezes if I choose Boot Android SD :/
Using 1.12

I would love to try "Windows 7 NAND and Android SD" even If it is complex. Do have a detailed instruction on how to do this, or know where I can find one?
Thanks.
i think in the future u should be able to dual boot both from nand if u have the 1024leo because the windows phone 7 rom only uses half of the nand

Hey...
Yeah, darren wrote an excellent tutorial, it`s pretty simple to dual boot with that (the partitioning only takes loooooooong)

I will add the link to a tutorial I made afterwards which includes his tutorial and adds the instruction how to boot Core Droid HD 0.4 as an option for an android build to actually dual boot.

I used this build (http://forum.xda-developers.com/showthread.php?t=801607) for over a month and all I can say is that this is the best Desire HD Sense build I've tried!!! (fast and stable)
So enjoy WP7 Nand and Android SD TOGETHER!!!

Dual boot from NAND only
Well, just the question I wanted to ask (OP, not the hijacking posts):
WM 6.5 (or WP7) NAND partition 1, Android partition 2.
At least that's the idea. Two OS's from the faster NAND memory, rather than the slower SD. Only applicable, of course, to the 1024MB version of the HD2. I know this is difficult, but if the chinese are doing it, why can't we ? This would just make this phone more awesome than it already is.
Can anyone answer if this is possible or not, and if not, why?

What chinese are doing it? I've never seen 2 OS's both on nand on a phone anywhere... even those cheap chinese fakes that claim to run both wm and android are just running android off the sd.
I, too, hope one day someone makes this possible... but not sure if it will happen or possible yet.
Also, HD2 NAND is not faster than a good quality SD in most cases. You might get a little better random access speed from nand, but if you find a good sd, even that is probably about equal. Even WP7 is now using SD cards as internal memory, now, but you need a good SD card that matches the NAND speed for it to work right. SD Android builds run at the same speed as NAND builds in most cases, but most SD builds aren't updated like NAND builds are.
But anyways, I agree that I would like to see 2 OS's from NAND on our phones.

I have a nice tutorial on how to do this. You have to be careful to choose the right SD Android Builds which you can use. There are only a few which are compatibe with SD Magldr. In my thread there are some of the more popular ones which has been converted to work with more coming shortly.
When Nand first came out there were a tutorial which I came across to convert SD Builds into Nand so in theory reversing the process you might be able to convert Nand back to SD and convert that to work with Magldr. It is something I have been wanting to look into for a few weeks now so I might just make it a priority of mine cause any build to dual boot with WP7 would be pretty awesome.
I think its possible, but its difficult because Windows properity OS may conflict with Androids OS so someone would have to configure it so that they both won't conflict with each other.
Thanks for the participation! That chinese bit was mostly to just stir the pot a bit .

Windows Phone 7 and Windows Mobile 6.5

Been away from the HD2 scene for a while, did a quick search but came up with nothing new since april.
Can someone tell me if it's possible to dual boot wm 6.5 and wp7 yet. Presumambly it would have to be wp7 on the ROM and wm 6.5 running from a partition of the SD?
Regards,
Mark

No, they both flash to NAND, neither can run from SD
Can the NAND be split to flash both OS's to the NAND and choose which you want at boot up?

Can't be done, especially since WP7 does a complete raidzero with any existing SD partition + 512 of NAND, you cannot currently repartition for both operating systems.
Plus MAGLDR, which is required for WP7, erases WM6.5 from NAND.
I don't think it will ever be possible.
Ok thanks for the info
