Hi all!
I've just installed C7 on my netbook that already contained Win7 (and also Fedora 19, which the C7 is intended to replace). The Fedora installer had found the windows installation and it appeared in the grub menu, and was bootable and worked fine.
The C7 installer did not put the windows installation into the grub menu.
with some googling I found a page at https://priteshugrankar.wordpress.com/2014/09/12/dual-booting-centos-7-and-w... that gives a simple recipe for fixing this problem. basically:
cp /boot/grub2/grub.cfg orig.grub.cfg grub2-mkconfig -o /boot/grub2/grub.cfg
with (on his system) the second command above producing this output:
[root@localhost ~]# grub2-mkconfig -o /boot/grub2/grub.cfg Generating grub configuration file ... Found linux image: /boot/vmlinuz-3.16.2-1.el7.elrepo.x86_64 Found initrd image: /boot/initramfs-3.16.2-1.el7.elrepo.x86_64.img Found linux image: /boot/vmlinuz-3.10.0-123.el7.x86_64 Found initrd image: /boot/initramfs-3.10.0-123.el7.x86_64.img Found linux image: /boot/vmlinuz-3.10.0-123.6.3.el7.x86_64 Found initrd image: /boot/initramfs-3.10.0-123.6.3.el7.x86_64.img Found linux image: /boot/vmlinuz-0-rescue-327fe33f3b364802871211321a2790b7 Found initrd image: /boot/initramfs-0-rescue-327fe33f3b364802871211321a2790b7.img Found Windows 7 (loader) on /dev/sda1 Found Windows 7 (loader) on /dev/sda2 done
Unfortunately, when I did it, I got this:
Generating grub configuration file ... Found linux image: /boot/vmlinuz-3.10.0-123.el7.x86_64 Found initrd image: /boot/initramfs-3.10.0-123.el7.x86_64.img Found linux image: /boot/vmlinuz-3.10.0-123.20.1.el7.x86_64 Found initrd image: /boot/initramfs-3.10.0-123.20.1.el7.x86_64.img Found linux image: /boot/vmlinuz-0-rescue-c875112952114f6284f69abaa4f9a2f7 Found initrd image: /boot/initramfs-0-rescue-c875112952114f6284f69abaa4f9a2f7.img done
No mention of the windows installation.
It's not that I use the win7 installation much, but I do want to be able to do so when one of those rare occasions pops up.
Thanks in advance!
