Install Windows7 + Ubuntu13.04 + Centos7

(Note: after using a USB flash drive to create a boot disk for centos7, you do not need to delete the package or copy the image file or something. You can directly use it after burning it, I tested the installation of two desktops and one notebook, but there is no problem, but during the installation, You need to modify the location of the USB flash drive, as shown below :)

During the installation process with a USB flash drive, on the installation page, press the tab key to modify or press the e key directly: (direct installation is not successful and needs to be modified)

Vmlinuz initrd = initrd. img inst. stage2 = hd: LABEL = CentOS \ x207 \ x20x86_64 rd. live. check quiet:

Vmlinuz initrd = initrd. img inst. stage2 = hd:/dev/sdb4 quiet

Among them, hd:/dev/sdb4 is the location of the USB flash drive, which may be different. I am here. Other friends who are browsing the Internet have sda1. I don't know if the USB flash drive is different or why.

After centos7 is installed on the third system, the system fails to Boot Windows 7.

Solution: Use centos as the boot System

Method: Modify the/boot/grub2/grub. cfg file, that is, add a script to the file to guide windows.

menuentry'Windows 7 (loader) (on /dev/sda1)' --class windows --class os $menuentry_id_option 'osprober-chain-xxx'{insmod chaininsmod part_msdosinsmod ntfsset root='hd0,msdos1'chainloader +1}

Or, add this

menuentry 'win7'{insmod chaininsmod ntfsset root=(hd0,msdos1)chainloader +1}menuentry 'win7 search'{insmod chaininsmod ntfssearch -f /ntldr --set rootchainloader +1}

I can see another method on the Internet to solve the problem. However, I did a test and it cannot be implemented. But write it as a reference.

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

Steps:

1. Switch to the root user

Su

2. execute commands

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

The execution details are as follows: Kernel [root @ localhost jiezh] # grub2-mkconfig-o/boot/grub2/grub. generating generating grub configuration file... found linux image:/boot/vmlinuz-3.10.0-123.el7.x86_64Found initrd image:/boot/initramfs-3.10.0-123.el7.x86_64.imgFound linux image:/boot/vmlinuz-3.10.0-123.4.2.el7.x86_64Found initrd image:/boot/initramfs-3.10.0-123.4.2.el7.x86_64.imgFound linux image:/boot/vmlinuz-0-rescue-70ff68ea7ac34677a25f45f3417dd76cFound initrd image: /boot/initramfs-0-rescue-70ff68ea7ac34677a25f45f3417dd76c.imgFound Windows 7 (loader) on/dev/sdb1done

After the repair is completed, you can see the Windows 7 boot after the startup and restart (it cannot be performed on my computer)

I made # sudo update-grub2 on Ubuntu

However, the above Windows 7 guidance can be implemented.
