Where is Grub located?

[nervynewman]

Is Grub on sda AND sdc, or just sdc? The first few lines of bootinfoscript seem incorrect. Are they just routinely added to every file?

The Grub menu will only load if the sdc drive boots first. Windows 7 is also on sda, not sdb.

I added Ubuntu using the install alongside another OS option to a drive that has programs that won't fit on the Windows 7 main drive. sdb is just for music and other media files.

[darkod]

What bootloader you have on the MBR of the disks has no relation to what OS is installed on the same disk. Win7 is on sda1 but you have windows bootloader on the MBR of sdb.

If booting from sdc works, just keep the settings in bios to boot from sdc and it's fine. You probably have a broken grub2 on sda from previous installs or attempts. It doesn't hurt if it stays there as long as you remember you have to boot from sdc.

[oldfred]

Any of the auto install options will typically install grub2's boot loader to the MBR of sda as that is assumed to be the drive you boot from in BIOS settings.

You can install grub2's boot loader from your install to any drive. And then set BIOS to boot that drive first.
sudo grub-install /dev/sdc

Grub also remembers which drive you used to install and on major updates will reinstall to that location. But if you are booting from another drive that may create issues.

#To see what drive grub2 uses see this line - grub-pc/install_devices:
sudo debconf-show grub-pc
sudo grub-probe -t device /boot/grub

You may just want to set BIOS to boot from sdc, but install the Windows boot loader to sda, so you can directly boot Windows in case of issues with Ubuntu.

Hi nervynewman

oldfred is correct as was my response to your previous thread.

Easiest way to fix sda if to boot in windows repair mode as previously suggested and type

FixMbrIf concerned about overwriting other disk MBRs then disconnect them until you have done the repair on sda.

Personally for dual boot system I install windows on sda.
I then change the bios to boot for a new hard drive and install ubuntu on new drive.

This means sda has windows MBR and if I want to run windows back up I select this drive from BIOS boot menu (windows can be picky if the MBR is not MS and the drive is not set as the first system drive)

Otherwise I boot from sdb which has grub and I choose either kbuntu (I prefer KDE) or windows if I don't care about running a back up.

You have a number of MBRs doing different things from previous install attempts so you can clean them up by running the windows fix. If you do not have a windows recovery/install disk you can get things on line to do the job

WinPE

[nervynewman]

Thanks again for all the help.

It seems as though my best option is to use grub only to run Ubuntu until I learn enough to try the dual-boot again. I'll just choose what OS to load from BIOS since they're both on different drives after fixing all this.



This means sda has windows MBR and if I want to run windows back up I select this drive from BIOS boot menu (windows can be picky if the MBR is not MS and the drive is not set as the first system drive)
Now I just need to fix the MBR to keep the windows sda drive from loading the grub rescue screen, but the commands durring windows recovery don't help

This all started when I moved Ubuntu from a slower HDD to a SSD, but did it the wrong way. The grub menu still shows a second windows loader line for sdc.

I want to completely remove everything related to grub and Ubuntu without erasing its partition, and then try again the right way? I still have all discs and image files.

Sorry to say the same things again. As I also wrote in the other thread, this should all have been started in the beginners section! jk

[dino99]

what you should do:

- boot on ubuntu
- run into a terminal:

sudo dpkg-reconfigure grub-pc
then select to remove grub installation

then, reinstall grub-pc on /dev/sda :
sudo apt-get install grub-pc

now, the grub bootloader is only installed on sda, and will deal with all the installed OS

[oldfred]

If Windows is sda, you want to follow dino's suggestion but use sdb not sda. Ater fixing Windows MBR change BIOS to boot sdb first.

Make sure BIOS is set to boot from sda and then do Windows repairs:
You can run the fixMBR to install the Windows boot loader or install a Windows type boot loader to sda. All the Windows boot loader really does is look for a partition with a boot flag and jump to that partition's PBR, partition boot sector.

How to restore the Ubuntu/XP/Vista/7 bootloader
https://help.ubuntu.com/community/RestoreUbuntu/XP/Vista/7Bootloader


Restore basic windows boot loader - universe enabled if error on lilo not found
Simply open Synaptic and Settings > Repositories and tick the box against the Universe repo in the Ubuntu Software tab. Close that window and click on reload before installing lilo with Synaptic or command line.
sudo apt-get install lilo
sudo lilo -M /dev/sda mbr
May show error messages about the rest of lilo missing, ignore, we just want MBR with bootloader.

[nervynewman]

I'd like to understand terminal commands more, but since I don't understand dino99's reconfigure grub commands, I finally used the Boot-Repair tool to change the drive MBRs, but only after accidently adding grub to all 4 of them. Now sda loads windows like it should, but if sdb(where ubuntu used to be) doesn't load grub it freezes the computer instead of saying that the bootmgr is missing. Its driver also says windows on it.

This is all fine for now, but are these generic MBR sectors okay to have at the beginning of each drive?

Boot-Repair also gave me an url after every change like http://paste.ubuntu.com/1584820 or http://paste.ubuntu.com/1584642.

Thank you yet again for the help, as I've learned more in the last few days than years.

I'll mark the thread as solved tomorrow,

Drive order changed and Ubuntu is on sdd as is grub's boot loader, so that is good. And the Windows boot loader is on the Windows drive.
It should not matter that it is syslinux not Windows. But you can change BIOS to boot Windows drive and run Windows repairs fixMBR to restore the Windows boot loader if you really want it.

Grub also remembers where to reinstall on major updates. I think you have to run dino's command to reset that.
#To see what drive grub2 uses see this - grub-pc/install_devices:
sudo debconf-show grub-pc
sudo grub-probe -t device /boot/grub

#to get grub2 to remember where to reinstall on updates:
sudo dpkg-reconfigure grub-pc
#Enter thru first pages,spacebar to choose/unchoose drive, enter to accept, do not choose partitions

I was confused yesterday when I saw "quiet splash" after dino's reconfigure command, so I stopped. Other websites say its just a boot screen.

The terminal window says "Found Windows 7 (loader) on /dev/sdb1" and the GRUB boot screen still has a "Windows 7 (loader) on /dev/sdb1" option that leads nowhere. If these are both from its boot loader* then I'll start another thread later if I can't fix it.

* I still confuse boot loader with MBR boot sector.

GRUB is only where I want it , so that's all for now. Thank you very much for the instructions.

In that case, please mark this thread as Solved from Thread Tools to help others and start another thread when/if you need. ;)
