[Q] WP7 with SD Card installation like Android etc?

Hi there,
I was wondering if it would be possible in the near future to have WP7 running of an SD card like with Android. Because now I've finally found a near to perfect Android build (SuperRAM by darkstone) because my battery life is even better than on WM! I would like to have the option to still choose this one as my daily driver, but I would really love to have a go with WP7. It would be great to have an Android build, WP7 build and maybe a Meego build (in the future) all on the same SD card, with windows still running on NAND. I'm no real techie so I dunno if it is too much to ask, but I would really like to know my possibilities. Thanks in advance.

Same here. I think il always want wm 6.5 as a default os. Theres no way im flashing wp7 until its run off sd card or ram. I really want an answer on this. Triple boot!

hd2 wm6.5 android and wm7 all in one?
so right now i have the wm6.5 as my main os and have android to use when ever i need or want to show it off. after iam done i shut down android and turn the phone on again and wm6.5 reloads. can i do that with wm7? i want to keep wm6.5 the way i have it now and be able to load android or wm7 when ever i want and the go back to wm6.5. is that possible? THIS WAS A POST I MADE ON ANOTHER THREAD. I HERE WOULD LIKE TO KNOWIF THIS IS POSSIBLE

I want the exact same thing. But after doing a bit of reading it looks unlikely at the moment. Its nand only. I guess we can just pray there will be a sd ram version in the works

it can be done its been posted on here somewhere but its a very long winded process.
search for a dual boot.thinking of doing this myself

just a hypothesis, but since wp7 formats the sd card when it is fllashed, and then acts as if it is internaal storage, even if you could boot wp7 from an sd card, you would need another one to use as internal storage. if it was possible to partition the sd card and use one of the partitions to boot wp7 and the other for storage, you wouldn't have any data space for android (pics, songs etc.) So back to square one...

Exactly what I am looking for
WM6.5 main OS, with Android and/or WP7 running off SD Card.

[Q] About to Flash WP7 couple of questions

I have done a ton of reading today but can't seem to find some last answers.
I do apologize, but I've been coming in and out of these forums for years and flashing various phones on occaision so I'm comfortable but no expert.
I have a TMOUS HD2 (yellow reset key) with the stock wm6 rom installed.
I've been running Android MDjGingerbread v.1.0 for a couple months and it's GREAT.
Now I want to try out WP7.
Questions:
1. I have everything downloaded and ready to go but am not sure about the radio. as I understand it I (as a tmous owner) have to MAKE SURE that the radio that's packaged with the WP7 doesn't get written? how do I do that? Or am I confused on this.
2. As I'm currently happy with the install I have on the SD card for android I'm going to remove this SD card prior to flashing WP7 So it doesn't get overwritten. HOWEVER I'm wondering will I be able to re-install this SD card after getting WP7 all set up and unlocked and doing everything needed to the SD card I use for the WP7 install.. .Can I remove that SD card and replace it with the one that has the Android Rom I've had such good luck with? and then boot to that android build from WP7 like I did from Winmo6? Or will I have to sort out a fresh android install to the SD card.
3. Are DFT WP7 roms already registry edited so they appear as HD7's or does that need to be done prior to trying to get an unlock code from MS. If so where's a link to that? I can't seem to find instructions on that.
LASTLY. I understand you can actually run all 3. winmo6 in nand and WP7 partition/Android Partition off the SD card.
What I don't get is if you have to Nand flash the WP7 first to get all the settings straight and copy that install to the partitioned SD card... THEN put the android build I want on the other partition? Or Can WP7 be run from SD card for the whole process? I'd prefer to just leave the stock rom alone. Although obviously not completely against it.
Any/All help is greatly appreciated.
Mods feel free to delete and PM me with links if I missed these answers in an obvious spot.

You do expect a PM from a mod, sending you links to obvious spots?
Hmmm... I guess that won´t happen. But maybe you read too much, overlooking some of the "obvious" spots inside the stickies of each subforum.
Anyway, now to your questions:
1) WP7 ROMs don´t come with Radio ROM parts.
Note: To install MAGLDR, check this thread here. Here you´ll learn about requirements. If you had a NAND Android build, you´ll be familiar with this - but please make sure to use MAGLDR 1.12 or higher with WP7.
2) There is a tutorial to dual boot WP7 and Android: Click!
3) The very first "Leo70" ROM is not jailbroken, virtually all others are
4) No triple boot possible yet, only WP7 and Android or WinMo 6.5 and Android.

Thanks So much.

Shoulda just kept reading. It's up and running 100pct now.
Just got to figure out why I cant get it to see the SD card.
but I think I saw some notes on that. I'll go back and read tomorrow.

[Q] Do I have to use the SD method if I want to keep Winmo?

I am about to install Android on my HTC HD2, and the advise I was given was that I must use the SD method. I just want to be sure.
I need a system where when I start the Phone Winmo starts up, and then I run another program to run Android, and then I can go back and forth (via reboot or some other way).
Thanks for your advise and information!

So far as I know, you'll have to go with the SD variant if you want to keep WinMo. That way, WinMo is only a re-boot away. It's the method I prefer as I'm not so taken with either Android or WinPhone to go for the full NAND flash.

yeah, you would need to use the SD card method, i would recomend using RAM builds because they are very fast!

Yes, you must avoid the NAND versions, cause these will erase your Windows Mobile ROM and replace it by a Android ROM.
Thus, you have to choose a build inside the "HD2 Android SD Development" thread.
But here inside it is not always simple. Cause for some SD builds you will need to flash MAGLDR to be able to boot these builds, while for others the old method of executing CLRCAD and HARET is much simpler.

Any chance to run wp7 from sd totally?

and use android in the nand? i want use wp7 only for make hd videos and use android for all days, let me know please

no.... it's impossible.... WP7 system not operate in that way... WP7 must be flashed to NAND and use SDcard as storage and RAM memory

it's a shame! with android is possibile and with wp7 not

I remember several months ago there was speak of cotulla creating a way to boy wm 6.5 via sd card too but i never heard anything since..maybe just because 6.5 has continued to lose favor

you cant boot WM6.5 by SD card either an doesnt SD android copy its self to RAM? WM2003 might be possible.
The clever chap has got some form or working WM5/6 Emulator working under WP7 if that has direct hardware support, im talking com ports etc, the HD2 would become perfect
course another interesting experiement would be running android via WM6 which is running on WP7, im sure it would run like **** if it was even possible but damn that would be pretty cool

Perhaps what you are thinking about was that there was some talk about a 3-in-1 DFT ROM for the US T-Mobile HD2 that would be able to run Windows Phone 7 or Windows Mobile from NAND memory and Android from the Micro SD card. When booting the phone it would be possible to choose 1 of the 3 operating systems. Other versions of the HD2 (such as the European or Asian models of the phone) do not have enough NAND memory for a 3-in-1 ROM.

is possible install wp7 and android in nand together?

"We (DFT Team) developing several interesting stuffs for LEO, like WM65 running from SD card!"
This is what I was talking about... from Cotulla's twitter..apparently that post was in January of 2011 though

i did some research on this with MS documents and i dont think its possible without it running like **** or having persistant storage issues. WM2003 didnt need persistant storage and ran mostly from RAM (thats why in the good old days if your battery died it reset!) so that might be possible although you'd probably run in to driver issues.
With Android you can more or less change what the OS does, with WM you cant
Essentially SD is very slow, you could build a form of loader that would install to SD but thats not ideal because you need to run the OS in RAM, RAM drives would do, but thats not persistant and WM didnt have a way of mirroring that data back to the SD. In essence, it was never designed to do it, and it was never designed to be changed, so its unlikely it will run from SD unless those issues could be resolved.
I think the 1GB HD2 was going to get a dual boot at one point, and this new emulator looks promising, thats about as close as we'll get i suspect, but then again, perhaps i miss understood what i saw..

I would guess that it all depends on what MAGDLR 2.01 has in its arsenal. Only time will reveal that. And, for sure it would only be possible on the US T-Mobile version of the phone.

Is there any one you can recomment me ....
usually I read about it and test ..... but I just want to give it a try.... and dont want to touch my running system ...so far.
Thanks for your help.

WP7 cant boot from SD.... must be flashed to NAND...

dxdy said it. Any Windows Phone build must be installed and run from the NAND memory. So you could backup your Android system (with NANDroid), backup SD-card, and install WP the way you'd normally do it. You'd always have your Android build backed up and packed away. It's easy to restore it, if you don't like WP.
Other than that, the only way to dualboot the two systems is with SD Android and some special SD-partitions, as far as my knowledge goes to.
