DL and Josh, you have given me the simplicity I needed. Yes my drives are all Sata. Your instructions are probably the best for me as I need it simple. Jawade, you are probably trying to give me fantastic expert knowledge, but unfortunately much of what you are telling me has gone over my head. Maybe I'll become advanced enough to do those things later on. But thank you very much for your sharing. Botox, thank you also, your instructions are clear and concise and they work in well with earlier instructions. You have also have given me confidence when I come to upgrade the Vista drive to Windows 7. I will leave the XP drive as it is. Thank you. Finally John, much appreciated. I have downloaded the instructions from the Windows web site link that you gave. I will also explore the Vista and XP mvps.og sites as well. Thanks to you for your help in helping me solve this puzzle. I live in a regional country area in Australia called Albury. Me, and others like me rely so heavily on getting information from great sites like this, and great people like yourselves, Thanks again David |
Dual Boot Instructions
Hi, David.
You've received plenty of good advice here. You don't really need more, but... ;^} Ever since WinNT4 (which is where I jumped in to dual-booting), the Microsoft dual-boot (actually multi-boot) system has consisted of two parts: The System Partition and the Boot Volume. For the official but counterintuitive definitions of these two terms, see KB 314470 ( http://support.microsoft.com/kb/314470/EN-US/ ). As others have said, those uninformed on such matters may think it strange that we boot from the system partition and keep the operating system files in the boot volume - but those terms are rooted in computer history and we're stuck with them. I see this as a figure "Y". It all stands on the upright portion, the System Partition. The boot process starts there, then proceeds to one of the two (or more) branches of the "Y", depending on what we select. (In a one-OS system, the "Y" looks like an "I", but the System Partition and Boot Volume still exist - and the distinction is still important.) The System Partition must be a primary partition and marked Active (bootable), and it must be on the HDD designated in the BIOS as the boot device. The Boot Volume may be a primary partition, but it also may be a logical drive in an extended partition on any HDD in the computer. If there are multiple Windows installations, each will have its own Boot Volume, but they will all share the single System Partition. (More complex arrangements are possible, such as creating a System Partition on each of multiple HDDs and changing BIOS settings to choose between them, as some have suggested in this thread, but let's keep it simple for the current discussion.) The System Partition can be very small (well under 1 GB) because all that is required to be there are the boot sector (512 bytes) and the few relatively small startup files. The Win2K/XP startup files are only NTLDR, NTDETECT.COM and Boot.ini. For Vista/Win7, they are only the file "bootmgr" (no extension) and the folder named \Boot, which holds the BCD (Boot Configuration Data). No matter where you tell Setup to install Windows, these startup files MUST be in the System Partition. All the rest of Windows (maybe 10 GB or more for Vista) will be installed in a single folder tree, named \Windows, in the Root of whichever volume you choose, which thereby becomes the Boot Volume for that Windows installation. This CAN share the System Partition - and that is the typical arrangement, especially for newbies and for new computers with Windows pre-installed. But this means that you can't format that Boot Volume without also wiping out the System Partition. (Win7's default installation on a new blank computer solves this by creating the System Partition as a separate volume with no drive letter, then creating the large boot volume and assigning it Drive C:. But that arrangement is not available to us when adding Win7 to an existing WinXP system.) WinXP's Setup.exe never heard of Vista or Win7, of course, because those did not exist back in 2001, when WinXP was released. But Vista and Win7 Setup knows how to handle an existing WinXP. That's the reason for the Golden Rule of Dual-Booting: Always install the newest Windows last. When Win7 Setup finds an existing WinXP, it does not delete NTLDR, etc., but adds its own bootmgr and \Boot folder alongside them, then rewrites the boot sector (after saving a copy of it). Later, on each reboot, the BCD menu includes an option for an "Earlier version of Windows". If you choose that, the BCD gets out of the way and lets NTLDR present the familiar Boot.ini menu - if there are multiple Win2K/XP options - or continues directly into WinXP if there is only one. Since you want to add WinXP to a system that already has Vista installed, you'll need to do some repair work after installing WinXP, but that's easier than it used to be. And upgrading from Vista to Win7 later should be easy, although Microsoft hasn't yet published the details of this transition. Well, that's enough for now. We could discuss drive letters and such, or creating multiple System Partitions on your multiple HDDs (for insurance in case one HDD gets damaged), but we can save those for another day. RC -- R. C.

What can I say, the reponses to my post have been fantastic and generous. As
is yours RC. The only thing, and I might be wrong about this, but I still feel a little uncertain about setting up the booting side of it. What I mean is does the "Earlier version of Windows" option occur automatically or do I need to do something? How do I physically set that choice up? If I'm overdoing the request let me know, I feel confident about the installation, it is just that last bit. "R. C. White" wrote: Hi, David. You've received plenty of good advice here.

Hi DL,
I really like your instructions, they are pure and simple. Why are so many of the other responses so detailed and technical? I don't get it. So all I have to do is disconnect the Vista drive from the motherboard, install the brand new drive and boot from the XP CD in order to install it. Then, once XP is installed, I shut down the PC. OK, then, I power the PC on and I have to go to into the BIOS and select which HDD to boot. Question. How do I set up a menu choice like 1) Vista, 2) XP, and away it goes, how do I do that?

If you install XP first, then Vista, Vista will setup the dual boot menu
automatically.

Hi, again, David.
In this post you are mixing apples and oranges. :( EITHER: You choose Microsoft's built-in system for multi-booting, which I've described (at length) in this thread. This always boots from the same System Partition on the same HDD each time and presents a menu. OR You create multiple System Partitions, one on each HDD, and reset the BIOS before each reboot. Each System Partition boots only a single OS, either WinXP or Vista. So far as I know (I haven't used this much), this does not offer a menu; you must reboot - and reset the boot device in the BIOS - each time. Using the built-in system, and assuming a single installation of Vista and a single installation of WinXP, the opening menu (simplified) would look like this: Which system would you like for this session: Earlier version of Windows Windows Vista If you choose Vista, Vista will be loaded and started. If you choose "earlier", WinXP will be loaded and started. I like the built-in system better, but the choice is yours. RC -- R. C.

Hi R. C.
I've read over your thread a number of times and it is beginning to sink in. I am new to this but the only way I'll learn is to do it myself. I'm just worried about the system not booting at all. If I slip up somewhere. I don't think I am thick but I'm probably thick as a brick where this is concerned. No one has said either yes or no to the proposed installation as described by "DL" in the first posting (other than Josh). It seems too simple that I just disconnect the already installed Vista drive, then plug in the blank HDD and install XP as per normal. Is this part correct??? Once the XP installation is complete it seems to be that once BOTH OSs are installed, then the fun and games begins, is that true? So If I am following your instructions BOTH HDDs will have a System Volume/Partition. The Vista volume will have a system volume - because it was already there. Because the Vista volume was disconnected when installing XP, the XP volume also will have a system volume. OK, if I wade through the instructions I've been given I will find an answer to this conundrum? I guess I can always take the PC to my local computer shop, where they will charge me by the hour and I will have still learnt nothing. Unfortunately, to learn something I may have to ask dumb questions, well I'm not afraid of that. If I encounter put-downs as a result of asking, then it is bad luck, I'll keep asking. Thanks "R. C. White" wrote: Hi, David. does the "Earlier version of Windows" option occur automatically Yes. Setup.exe in either Vista or Win7 will automatically create this as the first of the boot options if it detects WinXP already installed on the computer. On later reboots, if you select (or let it default to) Vista or Win7, this "earlier" line will be ignored, of course, and your Vista/Win7 selection will be loaded and started, just as you would expect. NTLDR, etc., will simply be ignored in that case. But if you select the "earlier" option, then Vista's bootmgr will turn control over to the saved file of the WinXP boot sector, which knows nothing of Vista but will look for NTLDR - and continue as though Vista/Win7 did not exist. As always in a WinXP-only system, if there is only a single WinXP installation, the boot process will not waste time presenting the Boot.ini menu but will simply boot the only choice. While you may not have tried, it, some of us have dual-booted multiple installations of Win2K/XP. We might have (or have had) WinXP Pro (x86) plus WinXP x64 - and maybe an installation of Win2K, all selected from the Boot.ini menu at startup. If we added Vista to that system, Vista's Setup would preserve that Boot.ini file. On each reboot, when we select "earlier", that previous multiple-choice Boot.ini menu will be presented. But if there is only a single choice in Boot.ini, that OS will be booted automatically after we select "earlier". RC -- R. C.

Dual Boot Instructions
Hi, David.
I'm probably thick as a brick where this is concerned. It's called "mindset" - and we ALL have experienced it. :( We all have known the "Aha!" moment when the "light bulb" turns on. Immediately, what was so complex a moment ago is now as clear as a bell. ;) It seems too simple that I just disconnect the already installed Vista drive, then plug in the blank HDD and install XP as per normal. Is this part correct??? Yes, it's just that simple, to this point. Once the XP installation is complete it seems to be that once BOTH OSs are installed, then the fun and games begins, is that true? Not quite. All you really need to do then is to update the startup files on your first HDD. You need for Vista Setup.exe to write its files there while preserving the WinXP startup files - and to create a menu to let you choose. (In all your posts so far, David, you have not yet told us how many partitions are on each HDD. Our job would be easier if we knew such basic facts about your system. For now, I'm assuming a single partition on each HDD.) Step 2: Leave the first HDD connected, with the System Partition on it - and WinXP somewhere on that HDD, too. (I would prefer it in a second partition, rather than have its boot volume share the system partition, but that point is optional and does not change what happens next.) Step 3: Connect your second HDD (with Vista and a second System Partition on it). Step 4: Boot from your Vista DVD and click Repair your computer. On the next screen, click Startup Repair. As a part of the repair, Vista will detect the existing WinXP and include the "earlier" version option in the startup menu. Repair should know to fix the first HDD, but it might do the second instead. That's OK. You can just set your BIOS to boot from the second HDD instead of the first. The computer will be just as happy that way. ;) I am new to this but the only way I'll learn is to do it myself. Yep! One thing for su You won't know until you try. A dozen more newsgroup exchanges will leave you still wondering - and without a working dual boot system. Do it - and then let us know what happened. You shouldn't have any problems, but we're here if you do. ;) RC -- R. C.

On later reboots, if you select (or let it default to) Vista or Win7, this "earlier" line will be ignored, of course, and your Vista/Win7 selection will be loaded and started, just as you would expect. NTLDR, etc., will simply be ignored in that case. But if you select the "earlier" option, then Vista's bootmgr will turn control over to the saved file of the WinXP boot sector, which knows nothing of Vista but will look for NTLDR - and continue as though Vista/Win7 did not exist. As always in a WinXP-only system, if there is only a single WinXP installation, the boot process will not waste time presenting the Boot.ini menu but will simply boot the only choice. While you may not have tried, it, some of us have dual-booted multiple installations of Win2K/XP. We might have (or have had) WinXP Pro (x86) plus WinXP x64 - and maybe an installation of Win2K, all selected from the Boot.ini menu at startup. If we added Vista to that system, Vista's Setup would preserve that Boot.ini file. On each reboot, when we select "earlier", that previous multiple-choice Boot.ini menu will be presented. But if there is only a single choice in Boot.ini, that OS will be booted automatically after we select "earlier". RC "DavidG" wrote in message ... What can I say, the reponses to my post have been fantastic and generous. As is yours RC. The only thing, and I might be wrong about this, but I still feel a little uncertain about setting up the booting side of it. What I mean is does the "Earlier version of Windows" option occur automatically or do I need to do something? How do I physically set that choice up? If I'm overdoing the request let me know, I feel confident about the installation, it is just that last bit. "R. C. White" wrote: Hi, David. You've received plenty of good advice here. You don't really need more, but... ;^} Ever since WinNT4 (which is where I jumped in to dual-booting), the Microsoft dual-boot (actually multi-boot) system has consisted of two parts: The System Partition and the Boot Volume. For the official but counterintuitive definitions of these two terms, see KB 314470 ( http://support.microsoft.com/kb/314470/EN-US/ ). As others have said, those uninformed on such matters may think it strange that we boot from the system partition and keep the operating system files in the boot volume - but those terms are rooted in computer history and we're stuck with them. I see this as a figure "Y". It all stands on the upright portion, the System Partition. The boot process starts there, then proceeds to one of the two (or more) branches of the "Y", depending on what we select. (In a one-OS system, the "Y" looks like an "I", but the System Partition and Boot Volume still exist - and the distinction is still important.) The System Partition must be a primary partition and marked Active (bootable), and it must be on the HDD designated in the BIOS as the boot device. The Boot Volume may be a primary partition, but it also may be a logical drive in an extended partition on any HDD in the computer. If there are multiple Windows installations, each will have its own Boot Volume, but they will all share the single System Partition. (More complex arrangements are possible, such as creating a System Partition on each of multiple HDDs and changing BIOS settings to choose between them, as some have suggested in this thread, but let's keep it simple for the current discussion.) The System Partition can be very small (well under 1 GB) because all that is required to be there are the boot sector (512 bytes) and the few relatively small startup files. The Win2K/XP startup files are only NTLDR, NTDETECT.COM and Boot.ini. For Vista/Win7, they are only the file "bootmgr" (no extension) and the folder named \Boot, which holds the BCD (Boot Configuration Data). No matter where you tell Setup to install Windows, these startup files MUST be in the System Partition. All the rest of Windows (maybe 10 GB or more for Vista) will be installed in a single folder tree, named \Windows, in the Root of whichever volume you choose, which thereby becomes the Boot Volume for that Windows installation. This CAN share the System Partition - and that is the typical arrangement, especially for newbies and for new computers with Windows pre-installed. But this means that you can't format that Boot Volume without also wiping out the System Partition. (Win7's default installation on a new blank computer solves this by creating the System Partition as a separate volume with no drive letter, then creating the large boot volume and assigning it Drive C:. But that arrangement is not available to us when adding Win7 to an existing WinXP system.) WinXP's Setup.exe never heard of Vista or Win7, of course, because those did not exist back in 2001, when WinXP was released. But Vista and Win7 Setup knows how to handle an existing WinXP. That's the reason for the Golden Rule of Dual-Booting: Always install the newest Windows last. When Win7 Setup finds an existing WinXP, it does not delete NTLDR, etc., but adds its own bootmgr and \Boot folder alongside them, then rewrites the boot sector (after saving a copy of it). Later, on each reboot, the BCD menu includes an option for an "Earlier version of Windows". If you choose that, the BCD gets out of the way and lets NTLDR present the familiar Boot.ini menu - if there are multiple Win2K/XP options - or continues directly into WinXP if there is only one. Since you want to add WinXP to a system that already has Vista installed, you'll need to do some repair work after installing WinXP, but that's easier than it used to be. And upgrading from Vista to Win7 later should be easy, although Microsoft hasn't yet published the details of this transition. Well, that's enough for now. We could discuss drive letters and such, or creating multiple System Partitions on your multiple HDDs (for insurance in case one HDD gets damaged), but we can save those for another day. RC "DavidG" wrote in message ... Hi I'm wanting to create a dual boot for my PC. I would like to use 2 separate HDDs. One HDD has Vista Business (current) and the other proposed HDD will have XP. I would like to locate some good user-friendly instructions on how to do this by downloading from a web site, or maybe someone on the group has a set of instructions. Could someone assist please? Is there a good site on this topic? I have tried Virtual PC 2007 but I cannot get the screen to enlarge to any extent. Full screen mode fails every time I try it. Anyway, I figure the twin HDDs would be the cleanest way to go. One more thing, I plan on upgrading the Vista installation to Windows 7 when released, would there be issues with the dual boot when installing Win 7?? Thanks |
