You'll need to write a custom GRUB menu if OS_Detect isn't working.
see this link: https://help.ubuntu.com/community/Grub2/CustomMenus
Also see if anything posted here helps: http://ubuntuforums.org/showthread.php?t=1476603&page=2
Don't worry about it being all about Ubuntu and CentOS, GRUB is GRUB. You just need to figure out how to get the right CentOS entry in your custom GRUB menu.
Good luck, and keep us posted on how you go.
Any additional questions feel free to ask.

If you know the partitions where Centos is installed. It shouldn't be to hard to fix. Otherwise boot Kali and run fdisk, you should be able to view the partition table. Be aware, don't change the table!

hi everybody
i've installed centos on my laptop.when i install kali on it, i can not boot to centos and my grub only show kali.i have searched alot.i really don't know what i have to do.
please help me ....

You need to execute os-prober, then run update-grub

That is pretty basic comming from someone using linux..update-grub will use templates in /etc/grub.d and /etc/default/grub and create a new grub.cfg.

The os-prober is a file which locates partitions in HDD or external devices. The os-prober template is under /etc/grub.d

Hope it helps. Try reading and accesing the templates under /etc/grub.d and the grub file under /etc.default/grub

Hello All

I am new in Kali, I just installed it yesterday night .

I have the same issue than Semofa , my previous os is a new gentoo.
Actually I am at work so I will work on Maverik35's advise at the end of the day.

By the way, yesterday I did a :
Update grub
he found my gentoo on /dev/sda3
But at the reboot he did not give me the gentoo's choice on the menu.

So I just have to edit and work around grub.cfg ?
right ?
