XP doesn t know which disk it has been installed on, and how to delete it.

You see if this drop-down menu has win7, right?,No, it's overwritten by you, so you don't choose to install disk partitions? The default should be c.

There is no merger, that is overridden, there is no more

Big brother, since you can do the system.

First, use a G disk or U disk to format the hard disk or C disk.

Second, it is recommended to re-partition the hard disk, at least 3 areas, and 4 partitions are recommended (the first two areas are less) (you can use it when redoing the hard disk).

The third system Win7 is installed on the C disk, and Win8 is installed on the D disk, and it is best to use the G system that can be partitioned.

It feels like your computer literacy is mediocre and I can't help you remotely. And the dual system is not recommended,The reason is that the current drive disk is basically the existence of too many instability factors,Dual systems may lead to system conflicts and other factors Anyway, there are many shortcomings,Especially for people who play games on the computer,Office doesn't matter。

One more thing: the above problem is because the system must be installed in a separate disk, and there is no dual system with one disk (not impossible, it is more troublesome).

If you choose the default when you install it, the system is generally installed in the C drive. No matter what system environment you are in, you can press the key combination win+r to run the msconfig command to bring up the system configuration window, manage multiple operating systems under the boot tab, set win7 as the default operating system, restart after saving, you will find that the previous system selection menu style is back, choose win7 or win8 operating system can be directly entered.

The default is in the C drive, see if there is a Windows folder in the C drive.

The landlord should not delete these write-protected system files without authorization, such files are important files for the operation of the system, and deleting them will lead to abnormal operation of the system.

XP for Win7, you can directly install it in the C disk, you don't need to pay too much attention.

1. Back up the data in advance, format the C drive, basically the C disk things, the desktop things will not be there;

2,There is a system,Install win7 will format out XP by yourself。

When installing the C drive, it will prompt you whether to format the C drive. Don't pay attention to anything.

Save the required files on the D drive and install them on the C drive.

C disk, unused software cleared out.
