Installing the WINDOWS7+UBUNTU13.04+CENTOS7 three systems

Installing the WINDOWS7+UBUNTU13.04+CENTOS7 three systems

(a point, after using a U disk to make Centos7 boot disk, do not need to delete the package or anything, do not need to copy the image file or something, burning is can be used directly, I tested two desktop and a laptop installation is not a problem, but in the installation, to modify the location of the next USB flash drive, as follows:)

In the U-disk installation process, in the installation interface, press the TAB key to modify or directly press the E key: (direct installation is not successful, need to modify)

Vmlinuz initrd=initrd.img inst.stage2=hd:label=centos\x207\x20x86_64 Rd.live.check quiet instead:

Vmlinuz initrd=initrd.img INST.STAGE2=HD:/DEV/SDB4 Quiet

Where HD:/DEV/SDB4 is the location of the U disk, may not be the same, my is this, in the online browsing of other friends have sda1, do not know is not the U disk or how different.

After installing the third system CENTOS7, I encountered the problem of windows7 boot without booting.

Workaround: Use the CentOS system as the boot system

Method: My practice is to modify/boot/grub2/grub.cfg this file, that is, to this file to add the boot Windows Script

Menuentry ' windows 7 (loader) (on/dev/sda1) '--class windows--class os $menuentry _id_option ' osprober-chain-xxx ' {
Insmod Chain
Insmod Part_msdos
Insmod NTFS
Set root= ' HD0,MSDOS1 '
Chainloader +1
}

Or, add this

Menuentry ' Win7 ' {
Insmod Chain
Insmod NTFS
Set root= (HD0,MSDOS1)
Chainloader +1
}

Menuentry ' Win7 search ' {
Insmod Chain
Insmod NTFS
Search-f/ntldr--set Root
Chainloader +1
}

On the Internet to see another way to solve the problem, but I did the test, is not possible, but still write a reference it

#---------------------------------------------------

Steps:

1. Switch to the root user

Su

2. Execution of Orders

Grub2-mkconfig-o/boot/grub2/grub.cfg

Details of implementation are as follows

-------------------------------------------------------------------------------------

[Root@localhost jiezh]# Grub2-mkconfig-o/boot/grub2/grub.cfg

Done

-------------------------------------------------------------------------------------

By the completion of this repair, the boot reboot can be seen Windows7 (on my computer is not)

I do #sudo update-grub2 on Ubuntu.

Can achieve the above Windows7 guidance
