correction of Grub after installing Windows XP and 8
 
Hi all after a while!
I've read many instructions about correcting boot list after installing Windows after Linux(here Ubuntu 12.04) like this link:http://www.dedoimedo.com/computers/grub.html
but in doing this command:
Code:

find /boot/grub/stage1

it syas that this file doesn't exist and really it isn't there a file with name stage1 in the folder.
I want to know where boot loader file is on the hard disk(whats the number of partition exactly)
this is the error:
Code:

grub> find /boot/grub/stage1
find /boot/grub/stage1

Error 15: File not found
grub>

and does it recognize the Windows's after correction(of Grub)?

Hi Ehsan,

Why didn't you install Windows XP and 8 first and Ubuntu as the last one? It would have avoided having this problem. Anyway, I guess it's too late now.

OK, so lets try and fix this. In theory, since you are using Ubuntu 12.04, you are no longer using Grub version 1, you are using Grub version 2. Therefore, that page is not the correct one to follow, it's the other one that it refers to at the beginning.

Problem is that the other page is really complex to follow.
Therefore, you should follow these instructions: http://howtoubuntu.org/how-to-repair...ubuntu-live-cd

Best regards,
Bruno

If you are not sure which it is, launch GParted (included in the Live CD) and find out
Hi dear Bruno,
in the site a software is mentioned as above,but has not described how to use it.I'm worry about choosing an incorrect partition and some problems originate again.
--------------------
I installed Grarted and used all the directions, but now only Ubuntu boots not the windows's,how to correct grub now?

Hi Ehsan,

What does the file "/boot/grub/grub.cfg" contain?

how I have to change it?I tried adding some lines before but didn't have any effect.

wyldckat December 15, 2013 12:02

You should at least be able to see an option in the boot menu, called "Windows 8 (loader) (on /dev/sda1)". That option should be able to boot Windows 8.

As for Windows XP, the grub updater was not able to pick it up. More specifically "/etc/grub.d/30_os-prober" was not able to see Windows XP. This seems to be related to the other situation you mentioned before: http://www.cfd-online.com/Forums/lou...-boundary.html

Problem is that I'm too tired to search and imagine which solution will work best. All I know is that this kind of problem is not something completely new.

immortality December 19, 2013 09:46

Hi Bruno,
It hasn't resolved yet :(

wyldckat January 1, 2014 17:01

Hi Ehsan,

Let's see if this will work:
  1. Boot into your working Ubuntu 12.04 installation.
  2. Start a new terminal.
  3. Switch to root mode:
    Code:

    sudo -s
    Be very careful with the commands you run in this terminal!!
  4. Install gparted:
    Code:

    apt-get install gparted
  5. Use gparted to help better see the partition numbers and to what each one corresponds to:
    Code:

    gparted /dev/sda
    If you're unable to figure it out on your own, send me a picture of what you are seeing in gparted.
  6. Exit gparted.
  7. Now, for each partition number you've identified, get the output given by the following two commands:
    Code:

    grub-probe --device /dev/sda1 --target=drive
    grub-probe --device /dev/sda1 --target=fs_uuid

    The first partition is "sda1", the second is "sda2" and so on. Some numbers might not be present, due to how the partitions were created. In your case, only number 3 is not present.
  8. Edit the file "/etc/grub.d/40_custom" and append this code twice:
    Code:

    menuentry "MYOSNAME (on /dev/sda1)" --class windows --class os {
            insmod part_msdos
            insmod fat
            set root='(hd0,DRIVENAMENUMBER)'
            search --no-floppy --fs-uuid --set=root DRIVEUUID
            drivemap -s (hd0) ${root}
            chainloader +1
    }

    You'll notice 3 upper case variables, which you will have to manually change accordingly:
    • MYOSNAME - This is the description of the Windows version for this partition, which will be shown in the boot menu. For the Windows XP one, you can name it:
      Code:

      Windows XP 32-bit
    • DRIVENAMENUMBER - This is the name+number given by the first command from the previous step. Usually it's "msdosX", where "X" is the number of the partition.
    • DRIVEUUID - This is the alphanumeric name given by the second command from the previous step. For Windows, it's either something like 1234-ABCD or 123456789ABCDEF0.
    • sda1 - This can change to the number you have, for example, sda5.
    For example:
    Code:

    menuentry "Windows XP 32-bit (on /dev/sda5)" --class windows --class os {
            insmod part_msdos
            insmod fat
            set root='(hd0,msdos5)'
            search --no-floppy --fs-uuid --set=root ABFE-1132
            drivemap -s (hd0) ${root}
            chainloader +1
    }

  9. Save and close the file.
  10. Now, to update grub:
    Code:

    update-grub
  11. Exit from root mode.
    Code:

    exit
Reboot the machine. It should give you several boot options now, among them the old "Windows 8 (loader)" which is automatically identified, as well as the references to the 2 entries you added. Choose one of them to try and boot the Windows version in question.


Now, since there is a very high probability that either one of the Windows versions might not boot, here's what I've done to get the Windows 8 installation up and running again. Partial reference: http://askubuntu.com/a/263931
  1. Insert the Windows 8 DVD into the drive and boot into it.
  2. Select the language, time and currency and keyboard settings and click "Next".
  3. Now click on the lower left, in the text "Repair your computer".
  4. Choose "Troubleshoot".
  5. Choose "Advanced options".
  6. Choose "Automatic Repair".
    • If this works, it should reboot automatically, after doing some repairs. When it reboots, it should show you the grub boot menu, so be sure to choose the entry for Windows 8.
    • Do not remove the DVD until you are safely in Windows 8 and everything seems to be working.
    • If this automatic repair step worked, then ignore the next steps.
  7. If the automatic repair failed, then it's because the Windows boot system got broken somehow. So, in the "Advanced options", choose "Command Prompt"
  8. Run this command:
    Code:

    bootrec /fixboot
  9. Run:
    Code:

    exit
  10. Go back to step #4 and redo the steps from there.
With any luck, this solves the problem. If not, let me know what error messages it gives you. And please provide details!

Best regards,
Bruno

immortality January 2, 2014 13:12

dear Bruno thanks for your valuable effort and help,but I think it be better to work as this way and manage to correct the boot list without need to super grub CD after my work finished.I don't need another bad chance again.:|
I'll test those later.
thanks a lot.

immortality January 3, 2014 12:35

Dear Bruno, I like to correct the boot menu now. but a little question.I have forgotten how to open the text files like 40_custom for editing in sudo mode:(

wyldckat January 4, 2014 20:27

Hi Ehsan,

You can use nano:
Code:

nano /etc/grub.d/40_custom
It's a terminal based text editor, therefore the cursor will not work with the mouse; but you can copy-paste text with the mouse, the same way you can on the terminal!

Then use Ctrl+X to exit, which it will ask if you want to save or not, to which you use the "y" key for Yes and "n" key for No.
If "y", it will ask to which file, where you simply have to press the Enter key for it to save to the current file.

Best regards,
Bruno

immortality January 5, 2014 07:16

dear bruno,
is this OK?
Code:

# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
menuentry "Microsoft Windows XP 32-bit (on /dev/sda1)" --class windows --class $
insmod part_msdos
insmod ntfs
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root F84026334025F8D0
drivemap -s (hd0) ${root}
chainloader +1
}
menuentry "Microsoft Windows 8 (on /dev/sda4)" --class windows --class $
insmod part_msdos
insmod ntfs
set root='(hd0,msdos4)'
search --no-floppy --fs-uuid --set=root 4E4C5FC94C5FAA8B
drivemap -s (hd0) ${root}
chainloader +1
}

there is no need to add Linux partition too?
-----------------------------------------------------------
dear Bruno,I did it and boot from hard disk,but only linux booted automatically and the list for boot didn't displayed at all.what may be wrong?

wyldckat January 5, 2014 08:52

Hi Ehsan,

Two details:
  1. Why are you using:
    Code:

    insmod ntfs
    When my example stated:
    Code:

    insmod fat
  2. The code you copy-pasted to here seems to be incomplete. Check if the first lines of each block end with:
    Code:

    --class os {
    Example:
    Code:

    menuentry "Microsoft Windows XP 32-bit (on /dev/sda1)" --class windows --class os {
Note: The reason why you only see "--class $" is probably because you did not maximize the window for the terminal.


Then check the content of the file "/boot/grub/grub.cfg" and search for the block of code that starts with:
Code:

### BEGIN /etc/grub.d/40_custom ###
Somewhere below it should be the code you have written. If it doesn't appear, then step #10 did not work correctly.

Best regards,
Bruno

immortality January 5, 2014 14:05

dear Bruno its a part of grub.cfg contains the line you said,it seems that grub isn't updated:
Code:

### END /etc/grub.d/30_os-prober ###

### BEGIN /etc/grub.d/30_uefi-firmware ###
### END /etc/grub.d/30_uefi-firmware ###

### BEGIN /etc/grub.d/40_custom ###
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
### END /etc/grub.d/40_custom ###

### BEGIN /etc/grub.d/41_custom ###
if [ -f  $prefix/custom.cfg ]; then
  source $prefix/custom.cfg;
fi
### END /etc/grub.d/41_custom ###

about
--class os { you are right.I copied it from the terminal.

this is the output of update-grub
Code:

in 40_custom there was a block that used ntfs in return of fat,I edited it with lines you said and copied for Windows 8 too,have I to change it to fat? and there isn't any need to add some lines for Linux too?

wyldckat January 5, 2014 15:36

Hi Ehsan,

It took me some considerable time to test the steps I wrote on the other post and to review them to ensure that everything was correctly tested and written.
Please do not make unnecessary adjustments to the instructions I carefully wrote :(
  • Use "insmod fat" as I wrote in the instructions. It worked fine for me, so only change to "ntfs" if and only if I tell you to use it ;)
  • If I did not tell you to add and entry for Ubuntu, then it's because it is not necessary.


Check the contents of the file "/boot/grub/menu.lst", as indicated by update-grub. It might be different from the file I told you to look at, namely "/boot/grub/grub.cfg", even though they should be identical.


In addition, double-check what those two files are, by running as root:
Code:

ls -l /boot/grub/grub.cfg
ls -l /boot/grub/menu.lst

Let me know what the two commands gave you.


Best regards,
Bruno

seems there is no entry for Windows's.
I corrected ntfs to fat and did update-grub.

Oh no, I completely forgot that you might have changed the grub version installed in the system.
I thought that you had the default version, which is 1.99 or 2.0... but it's very likely that you have got grub 1.5 installed instead...

OK, if I'm not mistaken:
  1. What does this command give you:
    Code:

    grub-install -v
  2. If it gives you version 1.5 or similar, then you've got the old stable release of grub. If this is the case, then:
    1. Edit the file "/boot/grub/menu.lst".
    2. Find this line:
      Code:

      hiddenmenu
      And change it to this:
      Code:

      #hiddenmenu
    3. Find this block of code:
      Code:

      title Windows Xp
      rootnoverify (hd0,0)
      makeactive
      chainloader +1

    4. To this:
      Code:

      title Windows XP
      rootnoverify (hd0,0)
      makeactive
      chainloader +1

      title Windows 8
      rootnoverify (hd0,3)
      makeactive
      chainloader +1

    5. Save the file.
    6. Restart the machine and check if the boot menu now shows you the Windows XP and 8 boot options.

dear Bruno I didn't change the default grub,but it seems is very old (0.97 ??)
Code:

ehsan@Ehsan:/media/Education/WR_kOmegaSST$ grub-install -v
grub-install (GNU GRUB 0.97)

I have to install new version of grub?

wyldckat January 5, 2014 17:44

No, no need to install a new one. I probably got confused with the version numbers. 0.97 pretty much refers to Grub 1.0 and 1.99 refers to 2.0.

Simply follow the steps that I wrote for 1.5, from the previous post.

Hi Bruno, it worked fine in showing the list but the time is very low about 1 or 2 seconds when showing the list,how can increase it.
and I want to have grub 2,how can upgrade to it?
