Grub 2 - Windows 7

[Cole]

I have not used Ubuntu since 7.10--so Grub 2 is particularly new for me and as such I am sort of lost.

I installed the Ubuntu partitions manually by resizing my main partition and creating a swap and ext4 partition in the new free space. Both my Windows 7 boot partition and the main (C:) partition are still in tact and there has been no data loss.

Grub2, however, did not automatically add Windows 7. I have no idea how to work with its syntax and I am also not very sure if grub handles Windows 7 differently than previous windows releases.

Could anyone tell me how to manually or automatically add my windows 7 partition?

Thanks!

$ sudo update-grub

I would run in terminal from 9.10 sudo update-grub as requested by SlonUA.

Reboot and if windows still is not in the GRUB menu do this:

Let's get a better look at your setup & boot process. Boot into Ubuntu. Come back here and use the link in my signature to download the Boot Info Script to the desktop. Once on desktop open a terminal (Applications > Accessories > Terminal) and run this command
sudo bash ~/Desktop/boot_info_script*.sh This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

When you run update-grub in a terminal, it will report back on every OS (and kernel) it finds, one row at a time. You should see it report on finding Windows 7, although it might say Windows OS Loader.

Having the same problem here, after a kernel upgrade to 2.6.31-19...

I'v been using 9.10 for a while and after a kernel upgrade it seems that the upgrade-grub script doesn't run the /etc/grub.d/30_os-prober and so it doesn't find oter OSses...

And upgrade-grub insists in generating menu.lst that I would think it's no longer necessary with grub2.

I need to see what you have on that machine. Do this:

Boot the Ubuntu Live CD/USB. Choose "try ubuntu without any changes", when the desktop loads come back here and do the following:

1. Download the boot info script. There is link in my signature.
2. Once downloaded move the boot info script to the desktop.
3. Open a terminal and run the command
sudo bash ~/Desktop/boot_info_script*.sh

This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

See here (http://bootinfoscript.sourceforge.net/) for more info on the boot info script.

Above link is to meierfra's Sourceforge web page.

Presence's script will show us what you have -- but if I had to guess, I would say you updated from 9.04 to 9.10 because that will not automatically install GRUB2 and running update-grub will simply rewrite the legacy menu.lst file.

[kansasnoob]

In deed run the Boot Info Script and post those results here. To be sure you don't have a "mixed bag" of legacy grub and grub2 files it would also help to see the output of:


grub-install -v


ls /boot/grub

Update: although this was really a fresh install of 9.10 I found out that the old grub replaced grub2 sometime after. I'm sure I didn't do it on porpose. I might have made some mistake and forced install of grub, removing grub2. But I'm also inclined to suspect some rogue dependency from some package I installed in the mean time... Anyway, it's solved. I forced the grub2 to install again and now everything works.

Thanks guys.

$ sudo update-grub

thank you!!!!

[crowdofone]

I found that placing an extra entry in /etc/grub.d/40_custom that was a copy of the Windows 7 entry from grub.cfg with the text highlighted in red removed worked for me.

Original Windows 7 grub.cfg entry



menuentry "Windows 7 (loader) (on /dev/sda1)" {
insmod ntfs
set root='(hd0,1)'
search --no-floppy --fs-uuid --set 2cb8b1f1b8b1b9a2
chainloader +1
}


Entry added to 40_custom



menuentry "Windows 7 (loader) (on /dev/sda1)" {
insmod ntfs
set root='(hd0,1)'
search --no-floppy --fs-uuid
chainloader +1
}


Ps. Remember to run either of these after:


grub-mkconfig -o /boot/grub/grub.cfg

or


update-grub

Hey Guys,

I feel I'm a little bit over my head in this.

I have a new computer running Windows 7 and Ubuntu, I first installed Windows 7 and after that Ubuntu. The partition scheme is as following :

/dev/sda1 SSD with Ubuntu 10.04
/dev/sdb1 NTFS for Windows and Games
/dev/sdb5 /home for Ubuntu

But my computer boots straight to Ubuntu, very nice but I would like to play Starcraft 2 once in a while so it would be great if I could get the option to boot to Windows.

Can anyone point me in the right direction? I have found some information but I find it very confusing due the huge differences between Grub 1 and Grub 2.

I ran the boot information script and I got the following :

I have read you entries. I have formatted an old partition containing XP. When reboot the system, grub 2 has deleted the windows entries loosing the windows 7 partition. When entering this option it sais "hall.dll is lost, replace it" (something like that..)
This is my result.txt

Windows combines its boot into one partition. Your sda2 shows part of win7 files and part of XP files but not all of either. You will have to run windows repairs to fix the windows partition as it is missing /bootmgr /Boot/BCD if it is win7 or boot.ini if it is XP. The missing hal error is often a problem with boot.ini (which you do not even have).

Your slackware says its root is sda1 which is now a NTFS partition??

It looks like you are missing the boot files necessary to boot windows 7. Here is a look at mine:


sda1: __________________________________________________ _______________________

File system: ntfs
Boot sector type: Windows Vista/7
Boot sector info: No errors found in the Boot Parameter Block.
Operating System: Windows 7
Boot files/dirs: /bootmgr /Boot/BCD /Windows/System32/winload.exe

Note the boot files in red and compare to yours.

You will need a windows 7 installation disk. Boot your machine and go into BIOS. Set the 1 TB disk as first to boot in the hard disk boot order. This is critical as windows writes it's boot loader to the MBR of the first disk to boot!

Save changes to CMOS. Continue booting off the windows media. At the prompt select repair windows. Then choose fix problems keeping windows from booting (paraphrased- sorry I don't use windows often). This will repair the boot function of windows. Reboot without the windows disk and see if windows boots. If it does reboot and go back in BIOS and set the 37GB disk as first to boot in the hard disk boot order. Save changes to CMOS and continue booting. Boot into ubuntu. Open a terminal and run
sudo update-grubThis will detect your windows boot files and add it to the GRUB menu. next time you boot you will be able to boot to windows from GRUB.

P.S. If you don't have a windows installation disk you can download an iso and burn it as an image to CD from here (http://neosmart.net/blog/2009/windows-7-system-repair-discs/). You can then boot from this CD and use the recovery console as described above. It is not a full windows disk, but rather contains only the recovery functions. You can not install windows from this disk.

Hello,
I also have a problem with Grub 2 not seeing Windows 7.
I installed Windows 7 on a NTFS partition and then Linux Mint Debian Edition
on a Ext4 partition. I only have one hdd and the result of Boot Info Script is this:

Any help would be appreciated!

I'm having difficulty as well... I installed 10.10 after I had windows installed and when I boot the machine, I can't see the grub screen on boot to even change the OS to boot:

Here's the /etc/default/grub file:

# /boot/grub/grub.cfg.

I have in /etc/grub.d a file called 11_Windows with the following script in it:

#!/bin/sh -e
echo "Adding Windows">&2
cat<<EOF
menuentry "Windows 7" {
set root=(hd0)
chainloader +1
}
EOF

When I sudo update-grub I get the following output:

Also, Windows7 is on /dev/sda (2 partitions, separate drive than Ubuntu, 100 MB & 250 GB, windows boot drive and windows respectively).

Does anyone know what the issue is and or how I can fix it so I can:
1. see the grub boot screen?
2. add windows to eh grub2 boot menu?

Please & Thank you in advance for any help you could provide. If there is anything else I can provide info wise, please let me know.
Thanks,
Steve

I'm having the same problem on a friend's computer as everyone else in the thread. The computer in question has sda1 as ubuntu and sda3 as Windows, with no other partitions.

When I run update-grub, I get the following output:

Grub only "looks on the same drive in partition #1"... does that mean it's not looking at /sda5?

Alright. I found a saved copy of the Recovery partition that was previously /dev/sda2 on an external hard drive; running the bootscript confirms that it contains the missing files.

I have no interest in returning to that partitioning scheme, though. Can I simply copy /bootmgr and /Boot/BCD, or even the entire contents of the partition, onto the windows partition, sda3? If not, do I need to resize or shrink sda3 and then copy the recovery partition back on?

+1! I've been bad about doing so recently but IMHO we should kindly ask that new problems be posted as new threads.

It saves us a lot of time ;)

[Quackers]

grantmeaname, you probably need to move the boot flag from sad1 to sda3 (with either gparted or diskpart) and then either, run startup repair from the Windows vista/7 repair disc 3 times, or go to the command prompt in the recovery console and run
bootrec.exe /fixmbr
This should get Windows booting again. If it needs a chkdsk, run it.
Once Windows is happy, you can re-install grub from the live cd/usb to get Ubuntu booting again.

[krisdg]

hi,

I get the same problem, after installing ubuntu 11.10
i messed up my windows7 partition who is on sda1

so i put the windows7 DVD to repair the system...
it seem to be ok now, the bootmgr is there again

can somebody help me ??

You have grub2's boot loader installed to ever MBR, but it looks like only the one in sda may be correct as it refers to partition 6, all the others refer to partition 5 and your install is in sdb6.

Have you tried booting from sda, a 500GB drive. You may have to try both 500GB in BIOS. I have two 160GB drives and it took me a while to know which was which in BIOS.

If not you should reinstall grub2's boot loader to sdb and use the windows repair CD to reinstall the Windows boot loader to sda. With multiple drives you want each drive to be fully bootable on its own in case the other fails. Be sure to use Ubuntu liveCD that is same version as your install, the newest grub2 only updates with the same version.

#Comments are anything after the #, enter commands in terminal session
#Install MBR from LiveCD/usb, Ubuntu install on sdb6 and want grub2's bootloader in drive sdb's MBR:
#Find linux partition, change sdb6 if not correct:
sudo fdisk -l
#confirm that linux is sdb6
sudo mount /dev/sdb6 /mnt
#If grub 1.99 with Natty or later uses boot not root.
sudo grub-install --boot-directory=/mnt/boot /dev/sdb

# If no errors on previous commands reboot into working system and run this:
sudo update-grub

Then set BIOS to boot from sdb.

http://ubuntuforums.org/showthread.php?t=1014708
#Reinstall grub2 - Short version
https://help.ubuntu.com/community/Grub2#Reinstalling%20GRUB%202

If you do reboot from sda, then you still should reinstall to sdb.
#reinstall from working (not liveCD) system - first find Ubuntu drive (example is drive sdb but use your drive not partitions):
sudo fdisk -l
#if it's "/dev/sdb" then just run:
sudo grub-install /dev/sdb
#If that returns any errors run:
sudo grub-install --recheck /dev/sdb
sudo update-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

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

thx for your reply

i reinstalled grub on sdb from running linux (no live) thru grub's sda
i tried to load windows (sda1) but i get the blinking cursos with no loading.. so i think my windows mbr is still corrupted...

i think i m going to try boot-repair and restore windows7 mbr
if it doesnt work i ll try a couple of command prompt thru W7 DVD

commands i found HERE (http://neosmart.net/wiki/display/EBCD/Recovering+the+Windows+Bootloader+from+the+DVD)

i ll let you know what happens

++

[oldfred]

When you chainload Windows from grub it bypasses the Windows MBR and jumps to the Windows PBR or partition boot sector. Windows MBR just jumps to the PBR so once grub passes booting to the Windows PBR it is just like Windows booting from the MBR to PBR.

You may need to repair the PBR with a fixBoot command or run chkdsk. Windows 7 has auto repair but you normally have to run it three times to run all the commands. If issues with chkdsk you may have to run it more than once. You have to run chkdsk until there are no errors as it does not fix everything on one pass.

[krisdg]

hi !

here is the thing :

i messed up my sda again with diskpart "clean" command.
i had to search for hours to get my partition table back.
i ran testdisk and some other stuff like that, nothing happend.
i tought i was good for a format and reinstall.
finally i get it back with loading a current_mbr.img saved with boot-repair. lucky me i saved it before !

now i had to put the boot flag to sda so that my W7 dvd finds my windows installation. Tried to repair several times but when i load thru sda i still get the grub's loading menu.

i load ubuntu back thru sda and set grub-pc installation to sdb
then ran a grub-update

when i command debconf -show grub-pc
the install devices is correctly set to sdb

i guess i have to put the boot flag to sdb and set it to boot to the correct drive (sdb) in the BIOS (not to hard to find, sdb=WDC /sda=Maxtor) // ok that works fine without putting the flag to sdb. i can now load grub/ubuntu from sdb

is there another way to completely remove grub from sda ?
thru ubuntu maybe...

thx for helping me ;-)

[oldfred]

You can use the Windows repairCD to run the fixMBR command. From repair console in Windows:

# is comment do not copy or type comments
BootRec.exe /fixMBR #updates MBR master boot record do not run if you still want grub

I think Boot-Repair will also install a Windows work alike boot loader Syslinux to the MBR.

Grub does not use boot flag, but a few BIOS (mostly Intel motherboards) require a boot flag on a primary partition to let you boot at all.

[krisdg]

ok i ll try that.. i m running a chkdsk /r right now
but it takes a while...

[krisdg]

hi again,

here's what i did :

Option Three: Nuclear Holocaust
Back at the main page of the recovery center, go ahead and select "Command Prompt" yet again from that list.

The first order of business is to make sure the MBR and bootsector contain the right references to the Windows bootloader:

bootrec.exe /fixmbr
bootsect.exe /nt60 all /force
Now we get rid of the old BCD registry, and create a new one instead.

Note: We're assuming that the boot drive is drive C: below. If your computer is configured differently, be sure to use the appropriate drive letter here instead.

attrib -h -s C:\boot\BCD

del C:\boot\BCD
bcdedit /createstore c:\boot\bcd.temp
bcdedit.exe /store c:\boot\bcd.temp /create {bootmgr} /d "Windows Boot Manager"
bcdedit.exe /import c:\boot\bcd.temp
bcdedit.exe /set {bootmgr} device partition=C:
bcdedit.exe /timeout 10
attrib -h -s C:\boot\bcd.temp
del c:\boot\bcd.temp
Now we have a clean, working Vista bootloader. But we need to add a Windows entry to it:

bcdedit.exe /create /d "Microsoft Windows" /application osloader
bcdedit.exe should return a message with a GUID for the newly-created entry, something like this:
The entry {c0dfc4fa-cb21-11dc-81bf-005056c00008} was successfully created.

You'll need to use the value that bcdedit.exe returned for you below, along with the drive letter for the drive that Windows is installed to:

Again, make sure to replace C: with whatever the correct drive is for your Windows Vista/7 installation.

bcdedit.exe /set {c0dfc4fa-cb21-11dc-81bf-005056c00008} device partition=C:
bcdedit.exe /set {c0dfc4fa-cb21-11dc-81bf-005056c00008} osdevice partition=C:
bcdedit.exe /set {c0dfc4fa-cb21-11dc-81bf-005056c00008} path \Windows\system32\winload.exe
bcdedit.exe /set {c0dfc4fa-cb21-11dc-81bf-005056c00008} systemroot \Windows
And, last of all, tell the bootmgr bootloader to list the new entry or else it'll remain hidden:

bcdedit.exe /displayorder {c0dfc4fa-cb21-11dc-81bf-005056c00008}

everything worked fine with no errors at all.
but i still cant get into my W7
always get that blinking cursors...
i m running out of ideas now
i pretty much tested everything

the w7 repair tool created a recovery folder with a boot.sdi and a winre.wim file.

there a some new files in the system volume information too

the chkdsk also ran without errors

i think i m out of options now

[oldfred]

You have gone beyond what I know about repairing Windows 7. I do not see what else you can do.

Some have used this which may repair or make it more complicated.

[krisdg]

thx for your reply.

i saved my files and made a fresh install of W7.
everything is back now.I just have to reinstall 2 years of programs lol.

i got my files back anyway.

i think the windows 7 boot system is the worst i have ever seen !

they should take example on grub's system ;-)

...i saved my files and made a fresh install of W7.

In the Windows 7 forums (sevenforums.com), they have tutorials that walk you through doing a Repair Install -- which, unlike what you did, would have left your data and apps INTACT.

If you want detailed help fixing ANOTHER OS's problems, it's often best to go to the forums that specialize in that other OS -- this is every bit as true of other Linux distros as it is of Windows OSs.
