Baidu Experience:
1-pack Win7, leaving space for Linux
2 Install Linux, note here is to "custom Partition", with the previous Win7 left, in fact, I this time is very rough lattice dropped a partition.
3 during the installation of Linux, you cannot use a portion of the hard drive that Win7 uses, and the boot program, such as GRUB, does not affect Win7 and installs to the/dev/sdax that is left for Linux. As for the details of the Linux installation, just be casual.
4 EasyBCD software, under online.
5 open EASYBCD to set the boot loader. The first is to add a new entry, followed by the Edit boot menu. When I add an entry, I find Linux, and when I edit it, I start Linux by default.
6 reboot, OH.
Another, the Linux U-disk installation disk is created under Windows, also with Ubootnetin, usage and Linux under the same.
