There is still a standard that most programs (and in the end, an operating system continues to be) and you can not install a lower version on a superior.
This rule is especially true for operating systems and more particularly when it comes to Windows Vista and Windows XP. In this case is the fact that not also use the same bootloader, and that although the boot of Windows Vista can boot from an installation of XP, the XP boot loader does not boot from an installation Windows Vista.
Often, by sheer ignorance of this principle, trying to install Windows XP on a second partition or on a second disc, but have already installed Windows Vista.
This results in the best case (ie, if you can complete the installation of Windows XP, which is not always) that the XP bootloader (boot.ini) is installed as bootloader instead of Windows Vista (bootmgr). But not only is this the problem is that much further as the files NTLDR NTDETECT.COM, although having the same name are different, as well as other files that Windows Vista uses to boot, which is not present in Windows XP, and thus inaccessible to Windows Vista, and this happens in all cases.
This is a problem that at the moment and with the proper tools for Windows, I have found no solution in order to maintain both systems, but there is a solution (also fairly easy) to retrieve the boot and then remove Windows Vista installation Failed Windows XP, all this without having to reformat and reinstall Windows Vista without losing anything of what we have in Windows Vista.
Let's see how we proceed:
First boot from the installation DVD of Windows Vista.
On the first screen we see the features of language we are going to install. This screen should not change anything, so we click Next to continue.
Then we were shown the next screen, which, having detected a version of Windows Installer installed, gives us the option to repair the equipment, which is the option we choose.
Select it and move to the next screen.
This screen shows the detected installations of Windows Vista (in this case). In case they appeared, we must point out that we want to repair the installation, noting that this system can not repair operating systems earlier than Windows Vista. Click Next and continue.
We then show the next screen, which asks what exactly we want to repair.
In this case we choose the first option that appears, which is Startup Repair. We click on the option and the system is responsible for the appropriate action.
Once these, we are shown a screen confirming that the transactions were made. Press Finish and return to the previous screen, where they must click on Restart. This will have taken and the process completed by our team since our start installing Windows Vista.
Remove traces of the installation of Windows XP
Well, we've managed to boot from the installation of Windows Vista. We shall now remove the traces of the installation of Windows XP that could be.
We want a team and press the right mouse button (normally bottom right).
In the menu that shows us going to the Manage option.
We will open the following window
in which, in the left menu, select the Disk Management option.
In the window where we draw the partition and we installed Windows XP with the right button. In the menu that shows select the Delete option volume. We see that we display the following warning window:
Accept (Yes) and continue.
The result is as shown in the picture below:
We created partition, but unassigned. We return to it with the right mouse button and displays the following menu:
Here and chose the option you want, or create a new volume on this partition (assign a drive letter and format) and either remove and dispose of that space as you want (resize the system partition, multiple partitions do ....).
In conclusion, it is open Windows Explorer and go to Tools -> Folder Options -> View, activate Show all hidden files and folders, and below, uncheck Hide protected operating system files (recommended).
We go to the drive where the system (normally C and delete the following files:
These files, in this location, are those in Windows XP, and even if it does not usually make anything happen, since not even Windows Vista are the best thing is to remove them.
With this we have finished repairing our team. And I say that I've only found two really effective and safe ways to have Windows Vista and Windows XP on the same computer. One is to install Windows XP first and then on another partition or another disk, install Windows Vista and the other is that indicated in the tutorial Installing Windows XP with Windows Vista. One way to do it, which is always more that I can have two hard drives.
