Some errors and solutions encountered when installing CentOS7.0 from a hard disk
1. Mount:no medium found and/dev/root do not exist both cases are unable to find the CentOS7.0 installation file, the problem is that when the boot file is set with EASYBCD, the installation file (. iso) is not specified in which hard drive Now above the error, input Cd/dev, and then input LS two commands, display the information inside will have sda#, #号是数字1-7, the general words are based on your original system inside the number of disks to number, I am the system last disk put CentOS installation files, So mine is SDA7, and then the boot file is set as follows title CentOS kernel (hd0,6)/isolinux/vmlinuz Linux askmethod repo=hd:/dev/sda7:/initrd (hd0,6 /isolinux/initrd.img then I can normally identify the system file location, go into the installation interface, and then the second error comes
2. After entering the installation interface, set the installation media location prompts error, the Chinese prompt is: Set the basic software warehouse error, English is: the error setting up base repository This mistake for a long time, only in an English website above found a solution, Root problem or installation file problem, click in it has two options, roughly the installation source from 1. ISO file, 2. From the network, click on the ISO file next to the verification, immediately error can only restart. The solution is to use the network installation source, first exit, set up your network connection on the Fourth network setup, make the network connection available, and then in the back to the first installation source settings, after the http://input buildlogs.centos.org/centos/7/os/x86_ 64-20140614, in the back of proxy (proxy settings) inside fill in buildlogs.centos.org:80, click Finish, this error is resolved. Set up the hard disk partition again
3. Hard disk partition error, regardless of the size of the/ /boot  swap set to how large, all become 2MB or 3MB (everyone is not the same), this I read on the Internet, some people say that first set/home mount point for 2MB, and then set other mount points can be resolved, but my, no, I finally use automatic allocation after the mount point capacity to become normal, and can not change the format of each mount point, error, I will use the default settings, this is to enter the normal installation interface. Finally began to install.
