Mounting centos6.0 based on U-disk

I tried to install centos6.0 on the Dell laptop, and the Win7 form a dual system, the installation process is as follows:
1. Use Ultraliso to make the U-disk boot disk, the boot disk to centos6.0 image file for the source production;
2. After the production is finished, delete the packet folder on the U-disk and copy the image file to the root of the U-disk;
3. Restart the computer, boot with the U disk, follow the steps to follow.
Another: Do not pre-partition the division before the installation, or leave a certain amount of remaining partitions, to Linux use
