I have two systems.,How do I uninstall the one that doesn t work ah 20.

Didn't you check the plate? How can there be two more?

My Computer --Properties --Advanced--Boot and Failback --Settings.

There's a "System Startup" option bar here.,Just delete the useless ones.。

In general, even if there are multiple operating systems on the same disk, when you boot one of them, the others are just some files, and it won't have any effect, good and bad!

You install the system on 2 different disks, you can format these two disks separately, the system disk cannot be formatted, rest assured.

Formatting method: Right-click on the drive letter to be formatted, type the quick format hook, and then click execute. Formatting will delete all data in the disk.

If you want to determine which is the real system disk. You can double-click on my computer, type %systemdrive% in the address bar to see which disk pops up, and the system is which disk.

It's not a problem with the two systems, 50-60% of the CPU is OK when it's just turned on, and it's not normal after a while? Sit tight.

1. First enter the system you don't want to uninstall, press the win key and the r key on the keyboard to bring up the run dialog box, enter "msconfig" in it, and press OK. Open the Microsoft System Configuration Center.

2. In the system configuration center, there are important settings about system startup items and system boot startup. Click "Boot", find the boot item you want to remove from the system, check it, and click "Delete" below.

3. Then right-click on the computer, select Properties, "Advanced System Settings" - "Startup" tab in the "Failure and Recovery", click "Settings" behind, select the default operating system as another system, in the example win7, click OK.

4、In this way,The default system to boot up is win7 ultimate version。 At this time, find the installation disk where you want to delete the system, right-click, select "Format", check "Quick Format", and click "Start". After the formatting is complete, the deletion is complete.

If your F drive only has Win7 and no other files, just format the F drive. If you have other files on drive F besides Win7, then you should first go to (Folder Options) to remove the tick in front of (Hide Protected OS Files), then select Show All Files and Folders in the (Hide Files and Folders) option, and then press (OK) to exit. Open the F drive and delete everything except the files you need.

As for the software installed in the win7 system,It's also a direct deletion.。 After deleting, remember to go back and modify it back (folder option).

Just format the F drive.

Just check the F disk, and that's it.

Don't listen to them, what format f disk, the kali linux I installed, directly formatted, and the direct boot items can't be opened, and they can be reinstalled directly. Everyone's environment is different, if you have important files in the computer, it's best to follow a safe method... Never format directly.

From personal experience, it's a virus. Because I met .........And it's more serious than the landlord's.

Mine was at first found that the keyboard input settings were incorrect after startup, because Wubi was directly launched when the computer was turned on, but my input settings were not like this.

So I uninstalled five strokes,More advanced than the situation you encountered,Only the uninstall input method is displayed,It took a while to get it,There is no action to uninstall other software at all。

After the reboot, the nightmare begins! The software of about 50GB is all gone, only the desktop icon is still there, all the software that does not have the self-protection function is gone, and only the software with self-protection and system lock protection is still there.

My heart was cracked, quite a blow, the first time I encountered such a silent and invisible virus, all anti-virus methods were used.

Solution: Finally, I found it in the Little Red Umbrella offline antivirus, "Quick transfer of user information." * "I forgot the name I caught in my computer, the extension. Yes, I was really defeated by this virus! Then start installing your software again.

According to personal memory, this kind of virus is currently infected through the network ****, as long as you do not deal with your antivirus software instructions for the time being, this virus is equivalent to invading your computer system.

The uninstall uninstaller in the software is called, usually the software uninstall is to enable this uninstaller, its task is: delete the registration information in the registry, and delete all the files in the folder where the software is installed, and finally delete yourself, and some need to restart to completely uninstall.

I've come across it too. Entire folders are usually deleted. For example, uninstalling QQ will delete d:

Programs Tencent QQ, but once I accidentally installed QQ to the root directory of the disk partition, resulting in the deletion of the entire D drive, it is recommended to use file recovery.

All the icons are metered, and it is estimated that the system is unstable and an error has occurred. But don't copy it. Just find the main program point of the software and send it to the desktop.

Your software uninstall function is really to uninstall the entire folder, which may be uninstalled by mistake.

The software on your computer should be an integrated driver package that you must have uninstalled.

What software did you uninstall?

Enter the XP system.

1.Insert the engraved Windows 7 installation disc (or load the Windows 7 image with a virtual CD-ROM drive).

2.Click "Start" - "Run" in turn, and the command line window will pop up.

3.Enter x: boot nt52 all force in the command line window and press Enter.

Note: x: represents your CD-ROM drive letter, or virtual drive drive.

For example, if the *** drive letter is f, type f: boot nt52 all force. )

4.Eject the Windows 7 installation disc (or uninstall the ISO image file from the virtual drive).

5.Restart your computer.

The computer will boot with the previous version of Windows that you already installed. The startup items of the Windows 7 system are gone, and the early version windows is gone, leaving only the startup items of Windows XP, which is basically successful.

6.Manually delete Windows 7 files and folders, such as program files, users, and Windows folders. Or if you don't have other important files, you can directly format the partition where Windows 7 is located, saving time and trouble.

You go directly to PE to delete all the system files of the D disk,Then go back to the XP system and delete the startup items of win7,C disk directly open the file and delete the startup of win7。

You see which disk you selected when you installed win7 and then formatted it.,And then modify the default system method of the system menu as follows:

My computer right-click - Properties - Advanced.

If you have two systems installed on their own disks, you can delete the disks that you don't want.

If Win7 is a C disk, it is still recommended that XP be reinstalled to the C disk!

Format the disk with win7 under xp,And then modify the boot on the line。

After formatting the C disk, buy an XP disk and reinstall it.

Log in to the system you want to keep. For example, if you have win7 and win8 dual systems, and you want to leave win7 and delete win8, log in to your win7. Otherwise, it's the other way around.

Right-click on "My Computer" and select "Manage".

In the management window, select Disk Management. Later, in the open disk management, you can see that there are two drive letters occupied by the system, the current system is the C drive, and the other system is another primary partition.

If you want to delete the win7 system, just right-click on the disk where win7 is located and select format.

It's not good after formatting, there will be a system selection when you boot up, and we need to fix the boot startup items. You can use ntbootatuofix this small software,Choose automatic repair or manual repair,Boot and delete the startup items of the win7 system.。

Of course, if you find it troublesome to fix the startup item, you can also enter the win7 win8 system and set the default startup item to win7 win8.

Watching a TV card may be a network problem or a hardware problem,But if you want to uninstall an operating system,Just format the partition where the operating system is located,But the general system will not cause the program to freeze。

It doesn't matter with dual systems, dual systems are the same when used with single systems.
