Windows 7/Installing Dual Operating Systems in Smartphones and Tablet Devices.


QUESTION: Dear Kevin

Is it possible to install multiple Operating Systems in a single Smartphone, Tablet Device ?.

i.e. Dual Booting a Smartphone or Tablet device with multiple mobile operating systems.

For examples :

1. Windows mobile 7 Os and Android 4.4 Os.
2. Android 4.4 Os and iphone os 7.
3. iphone os 7 and Windows mobile 7 Os.

Awaiting your reply,

Thanks & Regards,

This is possible and depending on the device you have, there may be instructions on how to do this already. I recommend searching for your device on and see if they have anything there.

QUESTION: Dear Kevin

Thank you.

Is it possible to have multiple BOOT ROM chips installed on the Mobile Devices viz Smartphones and Tablets ?.

Example : ROM 1 has Bios program option, ROM 2 has Windows 7 Os installed, ROM 3 has Android Os Installed on the Smartphone/Tablet Device.

The user gets a option to select BIOS program FROM ROM 1 chip
i.e. By pressing specific function key or any other key on the smartphone or tablet device which can access BIOS program.

If user selects Boot from ROM 2, Windows 7 Os will boot from ROM 2.
If user selects Boot from ROM 3, Android Os will boot from ROM 3.

There could be three combinations for these.

1. Theoretical correct, Practically easy.
2. Theoretical incorrect, hence Practically not possible.
3. Theoretical correct, Practically difficult but not impossible.

Similar to multiple Hard disk drives, Multiple LAN Cards, Multiple RAM Chips etc installation in a single computer, I feel it is possible to install multiple ROM chips in the Smartphone Device.

i.e. I Feel Theoretically yes.

Now remains the question of implementation, so it could be probably
option 3.

Awaiting your reply,

Thanks & Regards,

I'm not familiar with installing a rom chip on a device. It may be possible, but you will probably have a better chance just installing the firmware/software and making the device boot from those OS. Again, this depends on what device you currently have. I would try asking this in XDA-Developers as they have been very successful in getting custom ROMS installed on phones.
