CentOS and Windows dual system boot issues.

At first, the computer system was a Windows 7 system, and then a CentOS 7 everything version was downloaded.  The downloaded ISO file was ultralso extracted to the USB flash drive into a bootable USB drive.  The installation process has many tutorials. But basically I don't have to, I used to install it in the VBox so it's not easy to set up.

One of the main points to note: The newly-separated windows of the hard disk space, do not assign disk characters, the separation is how to do. Otherwise, the installation of CentOS will show a lack of space, and reclaim space will also enter the debug mode, small white one, simple mainly.

when installing, remember to choose Gnome, or the character interface.

Starting again after installation will appear only for the CentOS operating system, not the previous Windows 7. There are many tutorials on the web to say what Grup under the catalogue or something.  I went to look for it, there is no ...   What else makes you/etc/... This may be the great God, but I did not find out, I do not. Little white taste just, really not very much.

What happens when I get here and start again and still get into the CentOS OS and not start Windows?   Don't worry, calm down.  With WinPE (PE can be made with a U disk, old peaches Ah, u disk master Ah, a lot of ...) can be solved, you can use the U disk first into the system, here to choose from the USB stick boot .   Cannot enter BIOS for this parameter. Because there is an input current password, God knows what it is. after entering PE, in the lower left corner click Start---> Click System Tools---> Repair boot area (here the specific later will map ~ ~ ~ Today is too late to get it.)

After the repair is restarted, you can find the boot from Windows 7. But there is a problem, and there is no Linux operating system to start. Obviously installed CentOS but did not discover when starting the operating system selection:,.....

This time can be set with a EASYBCD software.  After downloading, you can choose to add an entry.  There are Linux options, below a drop-down option must be selected GRUP2 This is to automatically find your Linux installation path. Here to save the exit.

Now the computer's dual system is installed, of course, a bit of trouble, I spent half a day to get.  I hope you will not go my way. Also, the online tutorial is not all-faith, because basically a lot of the same, the answer is the same ... No words ...

Now the dual system has been installed, gentlemen play happily.
