XP system,Reinstalled,Open my computer to enter the DEF disk, I can t double click.

Your other logical disks have viruses,Use the upgrade to the latest antivirus software to kill the virus and restart the computer and it's fine,If there is no important data in other disks, you can also grid,I estimate that your current C disk is also the disk that installs the operating system because of other logical disks and infected with viruses,It's best to fully disinfect as soon as possible。

Your machine has a virus, haha.

Just delete the hidden files inside, if it's just virus remnants, the file will no longer be released, otherwise the file will be re-established after deletion.

**When you need to log in, you can register yourself, it's a very simple process, you can also use mine for free, username: iiiyel password: kkkkkk rose virus introduction:

Double-click can't open the disk.,There's an extra ** or something in the right-click menu respectively under Windows System and System32,Note that the 0 of N0TePad here is a number,Of course,It's easy to identify on the icon.。。

Windows system.

There is also one under system32. It should be noted that it is random and may be other names. For example, run552, run662, and so on. The icon is very well distinguished, the condition is to be.

Open the Hidden Files setting.

Finally, don't forget to delete the IE cache and the contents of the temp.

If you enter the virus, you can kill the virus.

How to install an XP system.

The first step is to set up the light enlightenment:

The so-called optical start means that the computer reads the optical drive first when it starts up, so that if there is a disc with optical start function in the optical drive, it can be read before the hard disk starts (such as when installing the system from the optical disc).

How to set it up:1Start your computer and hold down the Del key until the BIOS setup window appears (usually with a blue background and yellow English text).

2.Select and go to the second item, "BIOS Setup". Find the item or group that contains the word boot, and find the three items in order: "first", "secend", and "third", which represent "first start", "second startup", and "third startup" respectively.

Here we can set it to "CD-ROM", "Floppy Drive" and "Hard Disk" in order. (If you don't see these three E texts on this page, usually the option menu on the right side of boot is "setup", then press enter to see) should select "first" and hit enter, and select cd-rom in the submenu that comes out. Press enter again.

3.After selecting the startup mode, press the F10 key, the E text dialog box appears, press the "Y" key (can be omitted), and press Enter, the computer will automatically restart, proving that the changed settings have taken effect.

The second step is to install the XP system from the disc.

Before rebooting put the XP installation disc, move the arrow key to the first partition of the fully automatic recovery system, press enter. The rest of the time is to wait until it comes to the desktop.

Choose to manually ghost to the first partition of your hard drive, and that's it, the other disks won't touch you at all.

This is to install XP first and then win7.

1. XP is installed in C disk, Windows 7 is installed in non-C disk, for example: E disk, the disk must be a blank disk in NTFS format (if some data is not completely cleared, please quickly format it once before installation, so as to avoid errors in the installation process), the size is more than 16G, 20G is recommended.

2. Put the best image on the non-windows 7 installation disk, decompress it directly with winrar, get a folder, and double-click the setup in it"Next", and then follow the prompts to do it, the installation process will be restarted two or three times, please don't move, the whole process takes about 20 minutes, of course, the length of time for different configurations will be different. (Reminder: Do not select Upgrade during the installation process, "Select Custom", and then select the disk where you are ready to install Windows 7 in advance, e.g

E disk. In addition, the activation code is not filled in first, and it is clicked directly"Next", use it again after the installation is completed"Activate the tool"Activate it. ）

3. After the installation is completed, reboot and you will see two selection menus, the first one is Earlier Version of Windows

i.e. the early operating system Windows XP; The second is Windows 7, and the default system is Windows
