There is a virus in the computer, and if you want to change the system, how to format the C drive? I

In the process of installing the system, you can format the C drive, if you use the ghost installation system, he will automatically overwrite the original things of the C drive.

If you're using the installed version, he'll prompt you to format it at the beginning of the installation.

Hello: You can use the system installation disk to format it.

Use Ghost higher version (available on the Internet) to overwrite the image file to the C drive, and use a partition magician, such as a DM tool, to move all the hard disk stuff out of other computers and portable hard disks first, which I did.

Enter the PE and you can format it!

The original C drive of the reinstalled system is automatically formatted, but some viruses do not work to reinstall the system.

Use the system disk,Adjust the first startup item to the optical drive start,Then put it into the system disk,Start the machine,Then enter the selection interface,Select"Install the system to the first partition",That's it,The later one is automatically completed。

Start your computer on a bootable disc and format it with the format c: command.

Are you sure the virus is on the C drive? After reinstalling the system, the virus will be automatically overwritten.

Just use the formatting tool that comes with the system disk.

Reloading will prompt you to format!

With the PQ partition tool for ghost installation disks, you can format all disks.

Open"My computer"In d, e, f....Right-click and click on the drive letter to format.

If it can't be formatted, keep pressing F8 when booting up, click Safe Mode, and then format it according to the steps above.

Also reinstall the system.

Don't make trouble for yourself, press del when you boot up, BIOS - > advance **device (first device changed to **optical drive) press F10, press Y. Reboot, put in the system CD, make a cup of tea, and go outside to see the scenery.

Steps:1Boot.

2.Keep pressing the del key, if the del key activates some BIOS functions in advance, press the prompts to exit and then continue pressing.

3.I entered BIOS (the one with blue background.) 4.Use the "Up" and "Down" keys to move the cursor to BIOS Advanced Config, no motherboard here may be different, but you just need to find Bootstep.

5.Use the "+" on the keypad to change the boot order and change the CD-ROM to the first one.

6.Put it into the installation disk and reboot.

7.Follow the prompts on the installation disk.

So the dog will be detailed.

Enter the DOS format.

Then go to the C drive.

format, and you'll be fine.

If you don't understand, I can ask you to do it for you.

In addition, if you install ghost and cover it directly, you can do it.

You can go into the DOS and format it with the format c command, or you can format it with the system installer on the CD.

Buy a system disk and install it back.,Follow the prompts inside to do it.,It will prompt you to format it first and then install the system!

Set the boot disk to CD-ROM under CMOS, and then find an XP disc and follow the prompts, and you will be prompted whether you want to format the hard disk during the installation process!

You can choose to install it completely when you install the system.

It's a bit of a hassle, but it's the easiest way for beginners!

Data recovery from hard drives.

1. Recover data from hard disk formatted by mistake.

In the state of the higher version of the DOS, the formatting operation information is established in the default state for recovering the formatted disk information, in fact, all the contents of the disk's DOS boot sector, FAT partition table and directory table are copied to the last few sectors of the disk (because the later sectors are rarely used), and the contents of the data area have not changed at all. We all know that in the DoS era there was a very nice tool unformat, which can recover disks that were cleared by the format command. If you have formatted a partition by mistake using the format command in DOS, you can use this command to try.

However, unformat can only recover local hard and software drives, not network drives. In addition to the above deformatting feature, the unformat command is also capable of re-repairing and re-establishing corrupted partition tables on the hard drive.

But at present, unformat has been a bit "powerless", and then use it to recover formatted partition method is a bit outdated, we can use a variety of recovery software for data recovery, such as using easyrecovery and other recovery software can be convenient for data recovery work. In addition, DOS also provides a miror command to record the current disk information for recovery after formatting or deletion, which is also effective.

2. Data recovery when zero track damage.

The main boot record area (MBR) of the hard disk is on the zero track. The MBR is located in the 0 track 0 cylinder 1 sector of the hard disk, which stores the hard disk master bootloader and the hard disk partition table. Out of a total of 512 bytes of HDD Master Boot Record sectors, 446 bytes belong to the HDD Master Boot Program, 64 bytes belong to the Hard Disk Partition Table (DPT), and two bytes (55 AA) belong to the End of Partition flag.

Once the zero track is damaged, the main bootloader and partition table information of the hard disk will be severely damaged, resulting in the hard disk not booting. 0 track damage judgment: the system self-test can pass, but when starting, the partition is lost or the C drive directory is lost, and the hard disk has a regular "creak......ScanDisk scans the C drive, and a red "B" appears in the first cluster, or the fdisk cannot find the hard disk, and the DM dies on the 0 track, which is zero track damage!

Zero track damage is one of the bad sectors of a hard drive, but its location is quite important, so if it is damaged, it can have serious consequences. If the 0 track is damaged, according to the current ordinary method, the data can not be completely recovered, usually the hard disk with 0 track damage, you can use the PCtools DE disk unit (or diskman) to deflect the 0 track by a sector, and use the 1 track as the 0 track to use. The data can be recovered by clustering through EasyRecovery, but the data cannot be fully recovered.

Hehe,Formatting the hard drive is easy to achieve,Just change a drive letter in ** can be achieved in a small batch!! So don't bother looking for this virus. Viruses are not usually so arrogant!

First, it depends on the transmission channel of the virus, for example, open the exe program to spread, where you open the program on the d: disk, the d disk will be infected. If you don't open the exe file, the D: drive won't be infected.

Second, look at the location of the virus infection, for example, if it is stored in memory, the disk outside the system is also easy to be infected, not to mention that the virus is stored on other disks.

In general, if the computer is infected with a virus, do not easily open other disks, and the degree of infection will naturally be smaller.

Therefore, if the computer is infected with a virus, do not easily open other disks, and immediately scan the whole disk with antivirus software after removing the virus.
