I can't boot into Windows 7 Professional after installing ubuntu version 11.10 alongside windows as a dual boot. Windows starts to boot after I select it from GRUB and then select "start windows normally from the error screen but then it stops during start up animation and "crashes" and reboots. I do not have an installation or repair disc for windows and windows is not registered as I built the computer in a class. I do not know if it is legit because of before mentioned reasons. Please help anybody who is familiar with ubuntu. Optimally I would like to just uninstall ubuntu altogether and have Windows 7 as my sole OS.

Specs: OS: Windows 7 professional x64, Ubuntu/Unity 11.10; CPU: Intel Celeron 2.6 GHz 64 bit; 2 GB of RAM; Built in september or october 2011. Offline. Homebuilt desktop PC.

Details: After selecting windows from GNU GRUB version 1.99-12ubuntu5 it displays:

                           Windows Error Recovery
Windows failed to start.  A recent hardware or software change may be the cause.  
If Windows files have been damaged or configured wrong, startup repair can help diagnose and fix the problem.  If the power was interrupted during startup, choose start windows normally. 

Launch startup repair(Recommended)
Start Windows normally

After I select Launch startup repair it displays (after similar heading):

1.  Insert installation disc and restart your computer.
2.  Select your language and click Next.  
3.  Click Repair.  

If you do not have a repair disc contact your system adminisrator or manufacturer for assistance.

Status: OxcOOOOOOe
Info:  Boot failed Because a Required directory is missing.  

Well, I'm the administrator and manufacturer so I 'm kind of SOL. Update: I found an iso for my version of windows here and will try making an installation disc next time I go to the library. I hope it works and I will update if it does. I can always try to contact Microsoft.

How did you install Ubuntu via Live CD or USB? If you have no access to the internet then we need to back up a bit and evaluate your situation. – Ringtail Apr 11 '12 at 1:25
usb iso somthing or other. – Piman3.14 Apr 11 '12 at 2:07 - rtm – Ringtail Apr 11 '12 at 2:19
I used the usb installer by and installed the .iso to my sandisc 4 gig usb flash drive. I think that both OS's have the same partition. I should have used th WUBI virtual OS. Oh regrets! I kind of rushed into it after i couldn't find the wubi (i didn't know what it was called until it was to late.) – Piman3.14 Apr 11 '12 at 2:33
If all else fails i was planning on a hardware upgrade so i could spap the hard drives but i only have that as a last resort. I would have to buy windows 7 though as well. – Piman3.14 Apr 11 '12 at 2:52

An easy to use application for this is boot-repair, the launchpad site for this application is here:

This won't work if he doesn't have access to the internet – Ringtail Apr 11 '12 at 1:27
Maybe but its 300+ MB and the only internet i have access to is mobile broadband.... – Piman3.14 Apr 11 '12 at 2:54

It might be helpful to provide more information on the specifications of the laptop. If the Windows has a recovery partition/tool this may help. I personally had the same problem which turned out to be overheating - it was fine if I left it for a few hours before starting. Long term it was solved by cleaning the fan. However I appreciate this is not necessarily your problem, just it is worth a try at least!

Specs: Desktop w/ Intel Celeron 2.6 Ghz; 2 Gigs RAM; OS-Windows 7 professional and now Ubuntu Unity 11.10. No ability to connect it to the internet. If anyone knows how to Uninstall Ubuntu w/o harming Windows and in relation to this issue PLEASE LET ME KNOW!! Thank you!!! – Piman3.14 Apr 11 '12 at 1:23
It's a home-built computer, where did you get LAPTOP from – Ringtail Apr 11 '12 at 1:28
I tried booting again but it didn't work: still crashed after grub. Also, when I firt try windows it asks whether to use repair/install or start normally. As I said before I dont have a disc. @Shaun Killingbeck thx anyway! – Piman3.14 Apr 11 '12 at 2:25

...I think that both OS's have the same partition...

If you installed to the same partition, you may have accidentally wiped out Windows.(Ref: Personal mistake) As a rule of thumb, you should have up to 1 OS per partition, no more. You could try to seek out a new restore disc or make the best of the situation and keep Ubuntu. Do you have another small partition named RECOVERY or one that shows as a recovery partition under Disk Utility? If so, try booting to that with GRUB(It should have a valid bootsector) using chainloader and restore from there. You may need to make an NTFS partition before you can do that, though.

Thanks, I tried to make a new partition via windows before installing ubuntu, but my computer was being a dino. – Piman3.14 Apr 11 '12 at 20:13
I don't have any backup partitions that i am aware of. – Piman3.14 Apr 11 '12 at 21:46
like i said, i have a home built. – Piman3.14 Apr 11 '12 at 22:37
@Piman3.14 Ok... You should have used the Ubuntu custom partition tool--It has the option to non-destructively resize. Now, you are limited to using GParted to resize your Ubuntu partition before creating a new NTFS partition for Windows. Also, to burn your ISO, simply open Brasero under ubuntu and use it to burn your ISO. – hexafraction Apr 12 '12 at 13:54
Yes, I used the partition tool in the installation window, but instead of "windows" and "ubuntu" in the slider I had "files" and "ubuntu". I gave ubuntu 30ish gig and I had 100 gig free so it couldn't have overwritten, right? As for burning the iso I was going to use imgburn onto a DVD when I'm at the library cause the ISO is 3 GB and the only other internet I have access to is limited download (mobile broadband). I think that MAGGOT (as I now call it, with justice) just overwrote windows bootloader or something to that extent. If I "download the disc" then that should work, right? – Piman3.14 Apr 12 '12 at 23:28

Just open the terminal in UBUNTU and try executing

sudo update-grub

solved my same problem once. I just hope you have not wiped out your windows.

I tried this and restarted and the same thing happened: Windows started to boot then crashed. Thanks anyway! – Piman3.14 Apr 11 '12 at 22:14
I am offline so that might be it. – Piman3.14 Apr 12 '12 at 23:01

From your Windows log post above, I can see that it is Windows problem not the grub. Try to boot your system again, immediately after the grub depress 'F8' and select 'Safe Mode' to see if you can go beyond booting to restore back your Windows. If that didn't work then, get a windows 7 professional installation disk or download the ISO image online, burn it to a DVD or USB and use it to repair the bootmanager and other corrupt files in the registry.

I'll give it a shot in a little while. THX – Piman3.14 Apr 11 '12 at 20:29
In the event that didn't work, where would i find an iso for free? And how would i go about using that? Like i said before, i don't like command lines and i will avoid the BIOS if i can. – Piman3.14 Apr 11 '12 at 21:27
I tried safe mode but it still didn't boot. It stopped and went back to GRUB. – Piman3.14 Apr 11 '12 at 22:05
I found the iso here but how would i go about burning it to a dvd? – Piman3.14 Apr 11 '12 at 22:20
Yes, of course. But, make sure you are using the right Windows version. Like yours is Windows 7 professional, download the ISO for it not other. – all4naija Apr 11 '12 at 23:39
