Hello,
I've installed CentOS 7 to work side by side with Windows 8, but is not listed in the boot menu after installing Cent OS.
i tried to add a custom entry and automatic detection using 40_custom and 15_windows, it says found Windows 8 on dev/sda1 ... bla bla bla but nothing happens after restart
I don't want to use Windows repair so i can't use centos anymore. i want to use centos and windows side by side.
any solutions?
Thanks in advance.

Re: Cannot dual boot with Windows 8
I had a similar issue trying to dual boot with Windows 8.1 Pro, and this worked for me.
I added the following entry to /etc/grub2.cfg
Try and see if that works for you.
I added the following entry to /etc/grub2.cfg
Code: Select all
menuentry 'Windows 8 (loader)' {
insmod part_msdos
insmod ntfs
set root='hd0,msdos1'
ntldr /bootmgr
}

Re: [Solved] Cannot dual boot with Windows 8
Thank you very much vimj, but it wasn't worked for me.
anyway i found the solution, after running the grub2-mkconfig i just realized that the "/etc/grub2.cfg" is not updated even if it's detecting the windows partition at the terminal.
after running the grub2-mkconfig, i just checked the section "### BEGIN /etc/grub.d/30_os-prober ###", and copied the menu entry from there in the terminal, as explained in the picture:
after that, i added the menu entry to the grub2 config file "/etc/grub2.cfg" in the same section "### BEGIN /etc/grub.d/30_os-prober ###".
and finally, i booted to the windows os
