Unconventional dual OS

By kirk227 ·
I have an unconventional dual boot system. I have XP Pro x64 on one HDD and Windows 7 Ultimate on another HDD. I know a lot of you are saying"boy, that's a stupid way to do it" or something like that. Anyway, it's done now and I don't know if M.S. is going to allow me to move W7 to the other drive. Depending on the mood of the tech they'll either say "sure man, no problema". Or you can get the guy who can quote the EULA chapter and verse and tel you the only solution is to buy another copy of W7. Technically if it's a different drive it's a different computer. Microsoft's 11th commandment I believe. Now my point. If I have to keep things status quo, some of the upgrades from ASUS who made the mobo are the same for both OS's. Others aren't. How big a can of worms might I open should I decide to try to update the utlilities, updates etc. from ASUS. Everything's up to date on 7, but every time I start to do an update on xp pro 64, I get very nervous. I would sure like some advice from some of you wiser folks than I on this one. Feel free to contribute and if you must,go ahead and tell me how I should have done it. There really is a reason though. It's just not a very good one. Thanks!

I'm sorry

by .Martin. In reply to Unconventional dual OS

but I'm not too sure what you asking.

from memory, the motherboard is the part of the computer that an OEM version of windows lives and dies with. as for a full version of windows, you can move the license from one computer, as long as it is only on one computer at a time.

as for the updates, what are you nervous about?

You're not making any sense at all ...

by OldER Mycroft In reply to Unconventional dual OS

Each install is on a separate drive - so, whenever you boot into whichever OS you happen to choose, you are effectively booting a self-contained computer.

I've never encountered motherboard updates that were OS-specific, they usually only apply to the motherboard chipset - not the operating system.

What do you mean by "I don't know if M.S. is going to allow me to move W7 to the other drive."? - Why would you want to? Which 'drive' are you going to move it to?

What you have at present is (I assume) working, so where is your problem?

Having 2 installs on 2 separate HDDs left me confused ...

by OldER Mycroft In reply to glad to know

Back in October 2009, the day after Launch Day, I installed Windows 7 twice onto the partitions on the same HDD. First was Windows 7 Pro 64-bit, then Windows 7 Pro 32-bit.

I did it so that I could continue to recreate posted problems within either OS - and have a degree of experience as to how each system behaved and draw a comparison between them. Five months on and I'm booting into the 32-bit install less and less each week, it's only got access to 3.5GB of the 8GB RAM (whereas the 64-bit accesses all of it) and barring one game, I've experienced no system-refusals.

Removing the 32-bit install is giving me a few headaches and as such I've not really tried as yet. BUT if each install was on a separate HDD...

How about..

if I have one HDD containing XP(primary) and the other HDD containing Vista. If i use fixboot on XP the Vista bootloader would be erased? I dont need to use fixmbr? Then for example I could dual boot with windows 7.

I'm pretty sure that won't work.

by Ron K. In reply to How about..

To dual boot I believe that you need to have both operating systems on the same drive. I've been wrong before. <br>
What I used to do when I had a similar setup was to enter the BIOS when I started my computer and turn off whichever drive had the operating system that I didn't want to use. That was pretty easy.

the only safe way is to have 2 HDD and then use dual boot with one OS on each drive.
My question is simple. Since XP is on the master HDD (in my case) I would like to erase Vista(on the second HDD) when Im installing Windows 7. Im not sure if XP would work fine afterwards. Does anyone know how it would turn out?

What you've been told is untrue.

by Ron K. In reply to But I have been told that ...

I installed OpenSUSE on the same drive as my XP Pro drive as an experiment. During installation I was aske where I wanted to create 3 partitions for openSUSE and I chose empty space. Upon rebooting I had a choice of which operating system I wanted to use. <br>
A very safe way to experiment and/or use some form of Linus IS to install it on a separate unformatted drive. That way all you have to do to boot to Linux or Windows is to turn on the drive you desire in the BIOS. <br>
I believe that there is software that I haven't tried that makes it easy to switch between operating systems while they're on the same drive but the names escapes me this morning. There's also such a thing as having a virtual machine, (VM) but I haven't tried that either.

Okay. I'm waking up here.

by Ron K. In reply to But I have been told that ...

If you keep XP on one drive and erase Vista on the secondary drive to install Windows 7, meaning that you'll need to choose which drive to boot to in the BIOS, you won't hurt either OS as they'll be independent of each other.<br>
What you are proposing to do is similar to what I'd do if I were to install Windows 7. It's a good idea. <br>

Ron maybe not quite so right here

by OH Smeg Moderator In reply to But I have been told that ...

Here it all depends on how your Hardware addresses the HDD's and which one if either is the Primary Boot Drive.

To test this out open the case with it turned off and disconnect the Vista Drive.

If the system boots the XP OS without problems though you may need to open the BIOS and set the XP Drive to Boot first you can delete the Vista Drive without a problem. However if the XP System will not boot after disconnecting the Vista Drive you can not safely wipe the Vista Partition.

This is to do with your individual Hardware not the way that the different OS's interact with it.
