Windows 7 won't boot after update

[shibazz]

I've been successfully running dual boot with Ubuntu 10.04 and Windows 7 for a few months.

After a batch update in Ubuntu my Windows won't boot.

When I select Windows Loader in grub it initiates the Windows loading screen then after a beat the computer restarts.

I ran "repair computer" from the Windows 7 disk, and it says something like "can't repair, please contact administrator/manufacturer."

I'm in over my head with this problem. I'm afraid my newbie self needs assistance in even diagnosing the problem :/

I hope I don't have to reinstall everything. If it wasn't for Adobes bias I wouldn't even have a Windows partition.

Some basic info:
3 partitions
1. Ubuntu 10.04 64bit
2. Windows 7 64bit
3. Shared File System

Windows has the boot flag in gparted.

I don't know what update broke my system, but I do remember seeing a grub update on there. So that's probably it.

I know the information given is not adequate to diagnose the problem. When requesting information if you could provide details on how to acquire it, that would be much appreciated.

Hi and welcome to the forums :)

Use a LiveCD to boot the computer and run the boot info script linked at the bottom of my post (instructions included).

Post the results back here.

Thanks.

EDIT: you don't say whether you can still boot Ubuntu. If yes, you can run the script in Ubuntu rather than from the CD.

[shibazz]

Thanks Rubi! :)

Sorry, my Ubuntu is fully operational.

I also did make a super nifty bootable USB, Linux is so cool like that. :)

I'll jump on this when I get home from work.

Thanks again.

[Rubi1200]

No problem.

Let us know if you need anything else.

[Rubi1200]

Thanks for posting the results.

It seems, as you suspected, that GRUB is not picking up the Windows install.

First try this command:


sudo update-grub
If that does not add it to the menu, then try this:


sudo os-prober

Let me know what happens please.

[shibazz]

I ran both those lines, no change.

"Sudo os-prober" does list Windows 7.

However, the Windows 7 Loader was/is already present in the Grub menu as stated in line 3 of 1rst post.

Although I did not give good detail to Windows failure booting process.

In Grub when I select Windows 7 Loader it starts to load then feeds me this error.

Status: 0xc0000225
Info: The boot selection failed because a required device is inaccessible.

Searching this error brings up two main scenarios;

1. Problems after installing Ubuntu
2. Partition problems/"corruption"

Mine occurred after the update.

On this error page I have two options (paraphrased);

1. Repair Computer
2. Start Windows Normally.

If I try to start windows normally that's when the computer restarts.

When I try to repair from the Windows 7 disc it tells me it can't fix it.

I tried again just now to see if maybe the other repair attempt was being moody.

Nope, failure.

I hope this is solvable. Thanks so much for your help.

[shibazz]

I just found an inconsistency.

At the top of my boot info script it says Grub2 is installed in the MBR, but my grub menu when I boot up at the top says 1.98

I don't know if this means anything, thought I'd throw it out there :)

[Rubi1200]

I am not quite sure what is going on because the results look normal.

The boot flag which Windows needs is on sda2 where it should be.

GRUB2 is installed to the MBR and points to the Ubuntu partition sda1 as it should.

(note: GRUB2 is 1.98; nothing to be concerned about there)

And, GRUB correctly identifies the Windows partition on sda2.

Moreover, all the correct boot files for Windows are also in place.

So, my conclusion?

Let's first try and purge then reinstall GRUB just in case there was some kind of glitch during the update.

You need to use the chroot method outlined in this fantastic guide by drs305:
http://ubuntuforums.org/showthread.php?t=1581099

If this does not get Windows booting again, there are some other options we can try, but first things first.

[sikander3786]

Grub2 is the code-name. The current version is actually 1.98. No problem ;-)

I would recommend to boot a Windows recovery disc and perform startup repair from command line instead.

http://www.sevenforums.com/tutorials/20864-mbr-restore-windows-7-master-boot-record.html

Once you are able to boot Windows successfully, re-installing Grub is just a matter of 2 commands.

[shibazz]

I tried purging and reinstalling grub.

The system was exactly how it was before (Ubuntu = Boot, Windows 7 loader present in Grub, but won't boot.

Then I tried restoring the Windows 7 MBR, it was successful.

Unfortunately, Windows 7 still doesn't boot.

It gives the same error as when it tried to boot from Grub.

Neither Operating System loads now.

Can I reinstall Grub from Windows Command Prompt so I can get back into Ubuntu? Code?

Otherwise, I'll have to go to the office tomorrow to pick up my Ubuntu USB installation.

Windows 7 failing to boot on it's own can't be good.

Is this thread still relevant to Ubuntu Forums now? Can ya'll still help me? :)

[wilee-nilee]

It may be that you have a corrupted boot set up and maybe need a chkdsk as well.

1) Boot with your Vista/Windows 7 installation disk. Hit <Enter> at the language selection prompt then hit <R> for Repair to get to the Repair section.
2) Select the command prompt (console) and type in the following commands:
BootRec.exe /fixmbr (#updates MBR master boot record...do not run if you still want grub)
chkdsk /r
BootRec.exe /FixBoot (#updates PBR partition boot)
BootRec.exe /ScanOs
BootRec.exe /RebuildBcd
http://www.sevenforums.com/tutorials/20864-mbr-restore-windows-7-master-boot-record.html

It sounds like reloading the mbr worked to boot W7 but Ubuntu if there is a setup needing a fix wont recognize it at times. Neither would the recovery disc you may have to point it at the C partition from the command line.

[shibazz]

"BootRec.exe /fixmbr" Command Prompt yields:


The operation completed successfully.When I run "chkdsk /r" Command Prompt says:

Windows cannot run disk checking on this volume because it is write protected.I am unsure whether to continue all Willie Nillie like, because of the error from "chkdsk /r". :)

Or, should I be addressing this "write protection"?

Standing by for illumination. :)

Not sure about write protected, usually it is volume in use and a do you want to run it at next start up Y/N.

[wilee-nilee]

Is there any little yellow triangles by the NTFS partitions in gparted right click them anyway and look in the information.

You can do a check on the same popup, but It is not the same as a ckdsk, exactly.

I think you had a borked W7 to begin with that needed some work, theoretically, the Ubuntu update isn't on the NTFS partitions and should have no effect unless it changed the bootloader.

[shibazz]

There are no yellow triangles in Gparted.

I went back to post #9 to bring grub back to life with a USB Live Ubuntu.

So I'm back at that point now (Ubuntu = Boot, Windows = No Boot).

It is very strange that W7 is this messed up after a Linux update, but it was working for months before.

I still have no idea how to fix this except to reinstall Windows7. Which would be unfortunate, and would it work for sure?

Any more ideas before I start erasing my labors?

[keithnerin]

I have almost the same problem. I just installed Ubuntu (and grub) on my comp that had Windows 7. Ubuntu boots and works fine, but can't boot in Windows now. Same as said above, it starts loading, then stops and restarts. Same messages when recovery disk tried. I need help please! I'm new to all this. I'm open to re-installing Windows, but don't even know how to do that at this point. You don't get "installation discs" anymore with Windows 7. I have the recovery disk, I can make a back up from my other Windows 7 machine (if that would work), and I have a downloader for Windows 7 Professional free from my school. I don't know how to proceed with that though. I can't open it in Ubuntu even to unzip, and don't know how to do that from the prompt commands. I tried booting from the USB but it won't, I believe because it is still compressed.

[Crim_Ferret]

I had this happen at one point going from Karmic to Lucid. I used my system recovery disk to re-write the Windows MBR which got rid of grub and Windows booted fine. Then I created a live cd, and used that to re-install grub paying particular attention to where it installed. It worked fine after that.

Hello, i have almost the same problem.

I have Windows 7 (x64) on my machine and installed Ubuntu 10.10 Desktop edition using a live CD.

My disk looks like this:


/dev/sda1 NTFS Windows 7 system partition (~100MB)
/dev/sda2 NTFS Windows 7 main partition (~100GB)
/dev/sda3 SWAP (~ 4GB)
/dev/sda4 EXT4 Ubuntu 10.10 main partition (~ 50GB)After installing Ubuntu 10.10 using the live CD I can still select Windows 7 in GRUB menu but after selecting it it wont boot and I'll get back to the GRUB menu after a few seconds. What's wrong?

I've run the boot script posted above, here are my results.

Any help is appreciated.
Thanks :)


EDIT: OKAY, I just tried spending some time to understand the log above:

This looks like I screwed up something. How should it look like? How can I fix this? Note: I had a WUBI (Ubuntu inside Windows) installation first but removed it and installed a "real" Ubuntu. Not sure why it points to a WUBI directory....
