Dual Boot Centos7 And Kali

I had Kali and Linux Mint installed and erased Mint to install Centos7. Grub was totally deleted and I could only boot into grub recovery. Many hours of cussing later I got Kali back, I can see Centos filesystem mounted on my desktop and in disk utility. I never finished setting Centos up as I was rushed out the door which probably caused the problem in the first place, for some reason it's raid and although it's 2 harddrives they are not set up for raid and 1 is Kali and 1 is Centos. The Centos boot folder is still empty after running grub-install on it twice and it does not show in grub. How do I get Centos as an option?

GRUB Can`t See My Second Xubuntu Partition

Hello, i hope i created this thread in good place

I have 2 linux Xubuntu 14.04 partitions
GRUB shows only one partition, i cannot switch user to the second partition too, but file manager sees it right.

In GParted it looks like this:
 http://s23.postimg.org/igpp2j1jf/Scr...5_19_08_53.png

the bigger dev/sda/1 partition is my old one which i want to boot with GRUB and use it

and /dev/sda/6 is new which i need to remove

But i cannot do this because GRUB doesn`t see /dev/sda/1, so what can i do?

My GRUB version is 2.02~beta2-9ubuntu1, i tried to update it with sudo update-grub but no effects.

Thanks for your effort

Update Grub Command Not Working

I have made a change to GRUB2 bootloader in etc/default/grub.
Now I need to run 'update grub' for the change to take effect.
However, the 'update grub' command on the terminal is giving this error message:
Code:
root@debian:/# update grub
bash: update: command not found

Can someone please explain why this command is no longer working?

I've had to make a change to grub because I tried to install a new distro which meant I had to alter grub.
The install wasn't successful so I deleted the grub file and then re-installed it.
The re-installed grub needs a change so I can get sound on my pc.
However, I can't add these changes because the 'update grub' command doesn't work.

I've checked the grub file with another debian distro and they are both the same.
So now I don't know if I need to check if a different grub file is the problem or anything else.
Can someone help?

Grub Directory Has Disappeared - Can't Reinstall Grub

I have tried installing a Ubuntu OS onto a partition (sda3).
When I had difficulties with the install, I decided to delete everything from the partition.

But now when I boot the computer, I get taken to the 'grub rescue' prompt.
I have tried to find grub in my other partitions (sda1 and sda2).
However, the command 'ls (hd0,msdos1)/' for example, does not show a grub directory.
It must've transferred grub to sda3 somehow and now I've deleted it.

I have debian live USB and am trying to install grub with:
Code:
apt-get install-grub /dev/sda

But I get the error message:
Code:
bash: grub-install: command not found

So now I don't know what's going on. Can anyone please help?

Live DVD - Grub Install Issue

Hello all,

I am new to linux but not new to PC's.

I am self taught in everything i know so far.

I have an issue i am looking for some guidance on, i have burned an ISO copy of AVLinux & booted from the Live DVD.

chose to install on partition & created all the necessary file systems etc with GParted then proceeded with the install.

Completed install but when i try to boot no joy.

I have EasyBCD installed on Vista to manage to boot processes.

I am able to get to Grub4dos window & grub> prompt.

I have tried many commands of which i have identifeid the partition is there as correct filesystem, when running the /vmlin....TAB command it locates the name of the linux distro, if i set the drive partition to makeactive it boots up saying no operating system them have to change it back to Vista.

I have two pics that show the grub configuration reading from the live DVD, the install appears to have some missing or not right as opposed to the DVD, can anyone assisst how i can fix this issue?

Do i have to copy each file over manually from the Live DVD's folders?

Cant attach images here so here is the differeneces,

these are the listing on the Grub configuartion being read using the Live DVD,

1. /etc/grub.d
2. /boot/grub/device.map

4. grub-mkconfig
5. grub-mkdevicemap--device
6. grub-mkfont
7. /boot/grub
8. /boot/grub/grub.cfg

Booting To Linux On A Win8 UEFI PC

Booting to CentOS Linux problem. I have an HP desktop PC with an AMD CPU and win8.1 installed on it with UEFI as the boot process. The CentOS7 DVD indicates that I have installed the CentOS successfully. When I boot the PC it does take me to a menu offering CentOS and Win8. Win 8 will boot correctly. However, when I try to boot to CentOS I get a screen that says “Kernel not found”. The boot loading process continues until it ultimately brings up a terminal login screen. When I try to login with my password and usr name it tells me that they are wrong. I suspect the Kernel not found is the real problem but I can't get into the CentOS program to see if GRUB or any of the other programs are missing or defective. So far I have not disabled the UEFI since I didn't think I needed to. Any suggestions?

Linux Mint 16 Will Not Finish Booting From My Usb

I am trying to boot Linux Mint from an 8gb Sandisk USB. I changed my boot settings and it boots into what I believe is called grub? I am given two options, Boot Linux Mint, Boot Linux Mint (compatibility mode). When I select either of them all I get is a black screen. I've tried many things to get around this, messing with my graphics card settings (within grub), different USB's (another 8gb and a 32gb), I tried Ubuntu and that just doesn't boot at all I go straight back to my UEFI settings. I'm very new to Linux and I don't just want to hop in, I just want to boot from my USB whenever I want to play around with it. Thank You

Note: I'm running windows 8.1 currently on a ASUS N550JV laptop. I've been using the UUI from Pen Drive Linux.

Grub-pc Package Failed To Install On Dual Boot Windows 7 And Pinguy OS

After creating a bootable usb using Universal USB Installer. I booted up the sytstem (Dell Inspiron N4110) F12 boot on usb, did the install, everything went well until after copying files and then the error message that "The grub-pc package failed to install into /target.. So i continued without a boot loader and now am trying to figure out how to get it back.
Previously i did a perfect dual boot of Kali Linux wherein the Grub boot loader was present. I did however uninstall Kali, reclaim HDD space, and even use EasyBCD to remove Grub(i believe).
Also worth noting is that before this dual boot with pignuy and after uninstalling kali linux i did a complete reinstallation of my windows 7 system using the recovery HD.

Now i would like to know how i could get grub boot loader back onto my system so that i can boot up Pinguy OS. Thanks
