They can dual boot because Android is an open OS and is free. It would be illegal to put Winmo on our devices without paying for the proper license.
Also, for what possible reason would you even want to do this? To use as a reminder of how primitive Winmo looks and was compared to Android?

I wanna dual boot with 2 separate sets of android for testing purposes
Sent from my Emotionless Beast of an Epic using the XDA App
I think yes, it would be possible. I wouldn't know how, but its been done on android before, and there is an alpha version being worked on already for the Sammy Moment at SDX and Samdroid.
And if this could be achieved it would be a great to help to developers.
I think I would like it just for the purpose of trying out new roms without having to give up my current rom, in case I don't like the new one.

if you do a full backup, flash a new ROM, restore data (only) and you don't like the new ROM, you can go back into recovery, restore full backup and voila.. you're back to the ROM you just backed up.
takes 3 minutes to do all this.
no need for dual boot IMO

I'm aware of that process but if I'm just wanting to tinker with a new rom, I really don't want to go through all that trouble. If I want to try a new Linux distro on my PC, I'm not going to ghost it, install the new distro, then restore the old image later. I'm going to throw the new distro on a second hard drive and dual boot while I decide if I like it. That way, I have a known stable OS, configured the way I want, just a reboot away.

I have noticed this as well, and a flash with odin plus reinstalling clockworkmod is the only thing that prevents it from corrupting your backups for future use.

I don't know. That's fine if you just want to try out a ROM one time, and quickly, or if you can do without your main ROM for a long time. I had a windows phone before I switched to Android. Having the "dual boot" was key to my switching to Android. I was able to install Android, set it up the way I wanted to (which took lots of time) and "play" with it whenever I had time, but at other times I needed to be able to switch back to my main phone. I'd switch a couple times a day sometimes (just a single click to go either way). After a couple of weeks of being able to work with Android I knew I'd be happy switching.
You could do something like this with backups and restores, but I honestly think it would get overly cumbersome. You'd have to backup your main ROM and then the second ROM. Every time you changed a setting or moved something around in either ROM you'd have to remember to make a new backup, or the next time you switched into that ROM all of your changes would be reverted back.
In any case, I don't know how possible it is to have dual boot, but I can certainly see a lot of advantages for some people.
HARET is what makes the WinMo android boot possible and is based on work done with soft/hard SPL. No Android equiv to HARET exists yet. However, a lot of work is happening with HBOOT due to the Vision G2 eMMC situation. I wouldn't be too far off if I were to speculate that an android HARET may be in our future.
Go check out this thread from the Eris forums. - Dual boot recovery hack
As I'm not intimately familiar with the inner workings of Clockwork, I don't know how plausible it is on the DX. It could either be really easy to port since we're already bootstrapped, or nearly impossible. That's a problem for a dev much smarter than me to conquer.
I will say that I tried it out on my Eris. The stock class 2 card was unbearably slow, a class 4 was tolerable, and a class 6 (which cost a small fortune) ran as if it was installed internally. Kinda neat, but not terribly practical for daily use.
Okay this is my first ever thread so pls dont bash on where its posted. So the problem is, is that my android on hd2 would stop working after I reboot my phone. Idk why but it just hangs at the boot screen, which is white and has HTC on it. This has happened with every android rom I use and I can't even find answers when I google the problem. I'm using the htc energy rom and a 32gb sd card.
Strange i have exaclty the same! i updated to MccM HD 3Beta two days ago. Ill try another now and see what happpen
Questions belong in the Q&A Forum
No bashing just a friendly bit of advise for future reference.
Mark.
I've been going through different android roms and everytime I reboot into the wm energy rom I can't boot back into android. At this point I'm afraid to turn of my hd2, but I need to so I can recalibrate my battery stat.

Android was smoothly worked before the problem.
And I feel it was not stable with the SD card, for example i put some files on it by using the USB and after I check them from the phone not all are there.
And the problem began when the android said "save remove for SD card"
After second it shakes. I remove the battery to reboot it and it is just can't complete booting to android. It is stop at HTC white start screen.
For me the same,
I use a Android rom and when I launch Android, it doesn't leave the HTC screen. I kept it running all night long, but it didn't work. All my contact and text messages are in Android and now I can't reach them anymore, what should I do?

I have problem booting to andriod too, since yesterday morning, i was using android, the screen was freeze, so i restarted the phone and reboot to android. So as usual, i went to the android folder and trying to boot to android, then i got this error message "The file HARET cannot be opened. Either it is not signed with a trusted certificate, or one of its components cannt be found. If the proble persists, try reinstalling or restoring this file." I have no idea why this happened all in a sudden. so I've tried many times and restarted my phone to see if it would help, but it didn't. then I thought maybe the android wasn't updated, so I went back to the forum and found the updated version, but mine was discontiuned. I downloaded a new build and I erased everything on my SD card and gave it a try, but the same thing still happen. I still got that error message. would anyone know why? I'm desparated to go back to android.
hi all, just got my hands on a htc hd2 and iv loaded [BUILD][19.12.10]-=MDJ FroYo HD v.4.6=-[FRG83D][kernel:MDJ S8.0] onto it no problem, got it running great, only thing is when i switch the phone off and back on it loads windows mobile again, then i have to run the android files again and let it install itself again, in the mean time losing all my settings, iv read theres a way to autoboot android on startup but cant really find anything about it, is this possible, and if so could someone run me through how to do it, wouldnt mind if it was just to reboot the android firmware, but when im losing all my settings and apps its no good, any help on this much appreciated as im still a newbie really to this phone.
When you boot up android from SD card, the first boot usually takes 10-15 minutes (varies from build to build). During this first startup, a new file in your android folder is created called 'data.img'. This is the file which your android build uses to store all the settings/apps/customisation etc.
When you restart your phone, before you boot into android, look in your android folder for 'data.img'. If it is missing then the android startup will take 10-15 minutes again, but if it is present it should only take 2-3 minutes. If it takes 10-15 minutes every time then you probably want to re-download the build and try again.
Also, dual-booting options are available, but check to see if this works first.

thanks mate, i noticed when i reloaded it again after switching off that my settings and apps were still there, which is good, but now id like to be able to boot straight into android, is that at all possible, im sure i read something earlier about it, but i cant find it again, would be cracking if i could load android on boot up!

try installing MAGLDR, it deletes WinMo en it has the option to install Android and WP7 in NAND, and it can load Android from SD

But the best of all: it has Tetris included
i just got my htc hd2 cause someone stole my old one, on my old one, it was easy 2 put android on the sd, with my new hd2 no rom will work, it loads, but when android turns on it will lag, and apps crash and say force close, and the market wont work, i tried this and mcc's 4.5 and its the same thing happening, what should i do?
Have you tried a full wipe in clockwork and then installed? Do that as your first option and if that doesn't work then Task29, reflash MAGLDR/cLK then clockwork and then your ROM.
im noob, i dunno what clockwork is and how 2 do that? and i never used mgldr/clk on my old hd2, i just did a simple drag and drop onto my sd card, then flashed it, and it always worked fine, now when it works, theres always problems, also, do you know how i can reformat my sd card? ty for help, appriciate it!

If you don't know all that stuff... you should not be trying to root or ROM yet. Go check out T-Macgnolia's post. You shoulld really read up on it before you monkey around with your phone.
Sounds like he's running from the sd card, not NAND. Have you flashed HSPL and radio yet? Please look around the forums. There are some excellent guides to get you started

yes i launched w.m first on my old phone, and it always worked i would go to clrcad and haret and it always worked just fine, i used americanandroid, but my new phone when i put android folder on my sd card, it boots, but it lags alot, and forces programs to shut down, wifi is slow etc.

Yeah you need to install HSPL and a new radio. Again, there are several guides on how to do this. Search around a bit. One thing though, if it was me, I would just install on NAND and bypass windows altogether. The guide linked above should tell you all about it and how to do it.

I thought I'd post here since I'm having a problem with android install and I'm a noob as well (probably more noob than the person posting here). I tried installing nand android on my HD2 and followed the steps exactly. At least I'm pretty sure I did. I installed MAGDLR, then the recovery, and then android. Everything seems fine when booting except it just hangs at the HTC screen. I left it at the HTC screen over night since I heard the first boot would be long. So now I am wondering what are my options. I wanted to install WM again so I can retry the android rom install but since it stuck at the HTC screen, device manager doesn't see it. I didn't brick it did I? Thanks for your help in advance!

Couple things, did you first install HSPL and radio? Those go on before anything else. Second, how did you install the rom? Through usb or through recovery? Lastly, if you flashed via recovery, how did you transfer the zip to sd card? CWM has been known to corrupt files during transfers. I would recommend using a usb card reader or through magldr's usb mount option.
Actually one last thing. Make sure you have selected the correct recovery size. A ROM requiring 150mb will work on a 400mb partiotion, but not the other way around.

It's actually MAGLDR that corrupts files, not clockwork.
It's most likely that you don't have the right partition size though. You can change the partition by going to your clockwork file on your PC, opening it, then look for a file 'flash.cfg' and right click on it and open it in a text editor, then editing the line "system ya | 150" to whatever the ROM needs. The '150' will most likely be 150, 300 and 400 etc. so just change the numbers and save it.
ok i will try and do nand, what is one of the best nand to use, ty so much for help.
Hmm maybe you're right skelly, not sure. Either way it's best to use a card reader.
Fly, I'm using typhoon cm7 version 3.0.0. I found that it's the best for me

I would have always said one of the CM versions... great ROMs. Finally tried MIUI this week in preperation for putting it on my woman's G2 (always thought it looked like a girly ROM). OMG I'm hooked! I don't think I can ever go back to CM again. It's blown me away.
But you cannot go wrong with the popular CM ROMs. I tried the Sense one also for the eyecandy I love... but none of them ran smoothly for me.
Last night I installed Gingerbread 2.3.1 on my HTC HD2.. Followed the directions exactly and was able to boot Android and customize and had no problems. Tonight, suddenly my buttons at the bottom (home button, start menu, back, etc) started flashing -- side note: if anyone knows why this happens and how that can be stopped please let me know!! --, I figured I would just restart my phone. Well, when I restarted, suddenly I had no service when I booted Android.
I have rebooted my phone in the different methods (reboot, recovery, and bootloader), tried powering it off and then turning it back on, tried putting it on airplane mode (dunno why) and then back off, took out the battery and sim and waited for 20 min and then put it back in... Nothing has had any luck.
When I boot Windows Mobile, I have a phone signal, but for some reason when I'm booting Android, it isn't there.
Anyone else have a similar problem or can suggest how to fix this? I really want to be able to continue using Android but that's not going to happen if it continues to have this problem...
Flash official windows again, then try NAND Gingerbread 2.3.4 Its great ROM and all works.

try a different rom, the flashing buttons was common on early builds of gingerbread
i take it you are using an sd version rather than nand ?
Try switching to 2G only and see if your signal is back.

Yes, I'm using SD version... To be honest, I didn't really know the difference, but from what I was told NAND basically erases Windows, right? If that's correct, I was afraid of the installation not going right and being stuck without a working phone.

I tried going to my settings to switch to 2G, but at first it was greyed out, so I couldn't even select it. Then I clicked Access Point Networks and went back and suddenly it was available to be clicked. I clicked it and went to another screen and for some reason decided to go back to check it and it had been unclicked and greyed out again....
Seems it's a problem related to your rom and not a hardware problem because it works on wm.
Im not familiar with SD roms, maybe you should try a different SD rom or a NAND rom and see if the problem is solved.
Hope u get it sorted !
Since it seems I just need to try a different rom, can anyone suggest a link? I think I want to try SD again just because if I'm having these problems I don't want to completely wipe Windows and not have something to resort back to if I run into something again..

Honestly I don't want to NAND it because I don't want to completely wipe Windows in case I have a problem again... (this is all assuming I understand NAND correctly)... Right now I have a problem so I was able to go back to Windows Mobile. Do you have any suggestions for another SD rom?
Not quite true. You can always go back to Winmo from Android Nand if you are unhappy with it. I used to think the same way but since taking the plunge I've always found it easy to reinstall Winmo in order to use my tomtom navigator
ROM wise there are various fantastic offerings with Android Nand. Some are even spotting the new sense 3. You can try either CoreDroid or LeoRC Mix.
For now head over to the Nand section and read the stickies at the top. There are ample and easy guides on how to prepare your HD2 for a Nand Rom and how you can return to Winmo if you don't like it. If you follow the instructions properly, trust me nothing will go wrong.
