It is not possible to upgrade and install Vista, only a clean one

Your current Vista system has been updated, which means it's newer than the one you installed on the CD. As a result, you won't be able to run the upgrade installation. However, you can repair the installation at boot startup, so that instead of a fresh installation, you will overwrite the installation and restore all the programs in the system to the version of the program on your installation disc.

However, since your system has been updated automatically, there may be some updated programs that cannot be deleted by the system during the repair installation, so it may cause system instability because the version is not uniform. Therefore, it is better not to overwrite the installation with a disc as a last resort, and it is better to use System Restore to restore the system to the optimal state you think.

Yours is that system, huh?

Windows XP Professional for Business UltimateWindows XP Home Home Basic Home for Business Ultimate.

Windows XP Media Center Home Premium UltimateWindows XP Tablet PC Business UltimateWindows XP Professional X64 No.

Windows 2000 no.

In addition, you need to start the installation disc as a boot disk to upgrade the installation.

Basic is not available by updating to Premium, not a version.

Have you used SP1 yet? If there is, uninstall it immediately before it can be installed normally. If the system is a Vista with SP1 integration, then it cannot be upgraded.

The bit installer can't run directly under the 32-bit vista, and the incompatibility is normal. It can only be installed by booting up using a disc boot.

The bit of Vista can't be upgraded to 64-bit Windows 7, it can only be installed cleanly, this is what Microsoft said, you can go to Microsoft's ** to check if you don't believe it. Of course, if you or other experts feel that Microsoft has reservations, you can try it, and if it does, don't forget to share it.

3.If you want to install Windows 7 to the same partition and not format, it is a dual system.

4.Either formatted with a clean installation, or dual systems, you look at the ......

Yours is a CD?

Put the disc in Vista, reboot, boot from the optical drive, and you're ready to install.

No, you were originally 32-bit, of course you can't upgrade to 64-bit, only reinstall 64-bit win7, you have a disc, reinstall one side on.

There are two ways to do this. One is to install a dual system, the other is to remove the 32-bit system, use the 64-bit one, you can install it with a CD-ROM, or install it with PE, you install it directly on the hard disk or install it with a virtual optical drive in the system is unsuccessful.

The 32-bit upgrade installation only supports the 32-bit one, and the 64-bit one can only be installed with a clean one.

According to my understanding, the 32-bit system cannot be upgraded to 64-bit, you just need to find a 32-bit win7 upgrade.

It's a notebook! Some of the built-in systems can't be changed! I can't fit it either! It's even more incompatible!

Inside there are their own home settings! I don't know, but my friend has this problem!

Workaround for bootmgr is missing:

Initiation management is missing ......

It is recommended to deal with it as follows:

If boot manager bootmgr in the root directory of the C drive is corrupted or missing, the system will prompt that the operating system cannot be found when you start the computer, which is similar to the NTLDR file loss of Windows 2000 XP.

In Windows 2000 XP, to solve this kind of failure, you first need to know that the cause of the failure is the loss of the boot manager, and then go to the failure recovery console, and use the expand command in the command prompt to extract the copy of the ntldr file in the installation disc to the root directory of the C drive.

In Windows Vista it is very simple, we don't need to know exactly what is causing the system not to boot, just follow this method:

1) First of all, make use of the Windows Vista Reject Strike Series 1 - Sesame Open Door method to introduce the method by using the Windows Vista installation disc to boot the system into "System Recovery Options" and click "Startup Repair" on it.

2) The system looks for the causes that may cause the startup failure in the set order. In the background of the system, the boot recovery checker automatically tests and analyzes Windows updates (which may also lead to boot failures if the patch installation fails), system disks, disk errors, disk metadata, target operating systems, boot logs, and other contents.

3) If the system finds the cause of the boot failure and repairs it, it will enter a dialog box indicating that it has been found and tried to fix the problem.

4) Windows Vista will not display the fault cause found by default, just click the "Finish" button to restart the computer to complete the recovery operation.

If you need to see the cause of the failure, you can click Click here for more information on diagnostics and repairs on the dialog box. On the dialog box that opens, we can see that the root cause found is that the Startup Manager is missing and that the required file repair tool has been completed successfully.

Choose to repair automatically or reinstall the system directly.

It's normal.

Move the hard drive cable or unplug it and reinsert it.
