System disk 10G is too small. You can use the pirated system XP. If it is replaced by the windows system itself, it will not be enough. When windows is installed, it will cost several gigabytes. In this case, you can only expand the capacity of drive C. The following are ways to expand the capacity of drive C:

Download and install Acronis disk controller suite V 10.0.2 160.

Option: install Acr ....

Enter the serial number: G47A9-MHA63-28KNK-JDDE6-ZAYR3.

Restart computer selection: Yes

Choice of increasing capacity: manual mode.

Option: Increase available space

Please select drive c, and then click: Next.

Take out space from disk D, so select disk D first, and then click: Next.

Enter the value of how much space you want to widen, which is based on the original capacity, that is to say, the widened C disk capacity = the existing C disk capacity+the capacity you want to input now.

Click the icon to submit the flag operation.

Then the software will restart the computer. This process cannot be shut down artificially. Follow the software. After the computer restarts, it will start partitioning. 10G takes about 30 minutes.
