Friend's book seemingly because of the installation of 360wifi and led to a system on the blue screen restart, although after the uninstall of 360wifi, but the problem is still, internet Google a bit, found online many netizens complain, but also some analysis of reasons, said is because 360wifi led to the network card driver problem. In the middle in accordance with the user's weapon, really toss a, and finally found that even safe mode is not going to, just, reload it.

Use their own 8G u disk to do a startup disk, copy a win7 system, the book is ASUS, plug the U disk, boot, directly press ESC, you can see it detected a U disk, then directly choose from the USB stick boot (you can also choose to enter the BIOS settings, a little trouble point). After the interface is selected into PE, into the PE find win7 installation files, click Install. Everything in front is fine. Select the "Where to install Windows" Step, select the C drive, then the following prompt: Setup cannot create a new system partition or locate an existing system partition.

The other action is this:

After the above problems, in the PE found Win7 image extracted folder, the folder is copied to a non-system disk, such as D or E or F disk;

Unzip the image to get the folder in the Boot folder, sources folder, bootmgr file, copy to the C packing directory, and then run->cmd, the command line to enter the quotation marks in the command, "C:\boot\bootsect.exe/nt60 C:";

Reboot (this time from the hard disk boot, if the BIOS set up from the USB stick boot, either unplug the USB stick to start again, or change back), then the normal win7 installation process, follow this process, I installed here successfully.
