need some help getting windows back.

i had windows vista basic x32 on a acer aspire 5315.
i used to dual boot windows, and ubunut, but after i upgraded to ubunut 10.04 it messed up my windows, as far as i can tell all of the windows files are still intact, the only problem is that i cannot log in into any profiles, i can go into safe mode, but i cant accomplish anything in it. i can access all of my windows files through ubuntu.
if anyone can help me out i will be amazingly happy :D

other info:
the computer came with no windows install disc, and i think the partition has been overwriten by ubunut.

if you need anymore info just ask :D

reformat. salvage any files you can

installing and uninstalling ubuntu is not much of a hustle unlike windows, so i suggest you to uninstall ubuntu first and see if windows is operating properly or not.

Good luck and please post back your results.

awesome i shall try uninstalling ubuntu :D

Hi lopezman,

Welcome to Vista Forums!

We'll need to do a general troubleshooting to see if we can identify and resolve the problem. Skip any steps that require booting into normal mode for now and then reply with results. Use the disk or safe mode where required.

Do you know when this problem began? Try a System Restore to a point in time BEFORE the problem began. Here's the procedure: http://www.vistax64.com/tutorials/76905-system-restore-how.html. Be sure to check the box to show more than 5 days of restore points. If the first attempt fails, then try an earlier point or two. NOTE: You will have to re-install any software and updates you installed between now and the restore point, but you can use Windows Update for the updates. Use the recovery disk if the system prompt doesn’t work. The recovery disk works a bit different from the above procedures but if you follow the prompts from the System Restore menu option with the above information you should be able to restore with no problems.

If the System Restore doesn't work, do a Startup Repair by booting to the genuine Windows Vista Installation Disk (or one you can borrow from ANYONE) or from a Recovery Disk with recovery options included on it. Here's the procedure: http://www.vistax64.com/tutorials/91467-startup-repair.html. To boot to the CD you may need to change the BIOS to make the CD-drive first in the boot sequence. To do that, wait for the screen that tells you the F key to push to access the boot menu or boot setup. Push it quickly. Make the changes, save your work, and exit. Put the CD in the drive and reboot. When prompted, push any key to boot from the CD.

If you don't have either disk, you can make a bootable Recovery Disk using http://neosmart.net/blog/2008/windows-vista-recovery-disc-download/ along with burning software like: http://www.snapfiles.com/get/active-isoburner.html and, of course, a blank CD (perhaps made on a different computer or perhaps in safe mode with networking if that is working).

If that doesn't work, try to boot into safe mode (repeatedly click the F8 key while booting and go to safe mode with networking – or do so from the command prompt on the disk). Then let's check some of your system files:

Go to Start / All Programs / Accessories / Command prompt and right click on command prompt and click run as Administrator (you can skip this step if using the disk).

If using the disk, cd to C:\Windows\System32. Type sfc /scannow and enter and let it run. It will scan and try to fix some of your system files. Hopefully it will complete with no corruption it could not repair (if there is such corruption post back here or try to analyze it to find the problem file(s) using http://support.microsoft.com/kb/928228. Try to attach the report (you may need to copy it to your desktop before it will permit you to attach it) here so we can see if they can be repaired with good copies from the installation disk (unless there are too many).

While in Command Prompt, type chkdsk /f /r and enter and let it run. It will want to schedule itself to run at the next restart. Answer yes and then reboot to run the program. It will scan and try to fix any corruption or bad sectors on your hard drive and mostly remove that as a potential cause.

If that doesn't work, then please post any error messages from the Event Viewer concerning startup (Start / Control Panel / Administrative Tools / Event Viewer). Here's how to use Event Viewer: http://www.petri.co.il/vista-event-viewer.htm. Look in the System section.

If you can get into safe mode, try to create a new Administrator user profile then see if you can boot normally using this account. If not, go back to Safe mode and activate the built-in Administrator http://www.vistax64.com/tutorials/67567-administrator-account.html and try to fix the user accounts with this and add additional Administrator accounts. Then reboot normally and see if you can access the newly created Administrator accounts. If so, your other user profiles may have become corrupt. To fix this use http://windows.microsoft.com/en-AU/windows-vista/Fix-a-corrupted-user-profile.

You may be infected with malware. Try to run anti-malware programs (in safe mode with networking if necessary). To fix this problem (if it is a problem) download, install, and run the following two programs: http://www.malwarebytes.org/mbam.php and http://www.safer-networking.org/en/index.html. You may also want to try the new, free Microsoft Security Essentials http://www.softpedia.com/progDownload/Microsoft-Security-Essentials-Download-131683.html (with the caveat that only ONE AV program can be installed and running on your system at any one time). Use removal tools when appropriate http://www.raymond.cc/blog/archives/2009/05/05/comprehensive-list-of-uninstallers-or-removal-tools-for-antivirus-software/. You may also want to try the free Avira at: http://www.free-av.com/ and Avast at: http://www.avast.com/index. Reboot after completing all the scans. You may also want to try the free OneCare at http://onecare.live.com/site/en-us/center/whatsnew.htm and let it run all the options (except the registry cleaner) because that’s good maintenance (it will take some time to complete but can be done in the background).

If that doesn't work, try a clean boot http://support.microsoft.com/kb/929135. If the problem goes away then it's just a matter of tracking down the culprit causing the problem. Follow the procedures in the article. Once found, delete, remove, deactivate, or uninstall it. Once done be sure to reset Vista back to normal status as explained in the procedures. If the problem occurs in clean mode then just restore the system to normal status and reboot - this solution is not going to work.

Boot into Safe mode with networking and see if the problem occurs there. Either result helps us narrow down the search for the cause.

You may be having troubles with your device drivers, firmware, and/or software. Go to Device Manager by going to start / search box and type device manager and enter and then double-click on the program icon that appears. Check each device for a red x, yellow ! or white ?. These identify devices with problems (probably drivers, but also conflicts or something else). Click on each for further details and troubleshooting tips. If you need to get drivers (and you should get any you have time to do - they may help in ways beyond just resolving this problem), do so from the computer vendor or device manufacturer (NOT from Microsoft Updates). In fact, you should turn off automatic driver updates from Windows Update as follows: http://www.addictivetips.com/windows-tips/how-to-disable-automatic-driver-installation-in-windows-vista/. Proceed as follows to get the drivers: http://pcsupport.about.com/od/driverssupport/ht/driverdlmfgr.htm. Once you have the drivers, you can install them through Device Manager as follows: http://www.vistax64.com/tutorials/193584-device-manager-install-driver.html. You may also want to try the Driver Verifier Manager to see if you can identify the driver or device responsible (assuming that is the cause): http://support.microsoft.com/kb/244617.

Let's test your hard drive and RAM for hardware problems:

To test your hard drive, check the manufacturer and then get the diagnostic utility from: http://www.techsupportforum.com/hardware-support/hard-drive-support/302602-hard-drive-diagnostic-utilities.html (and/or get one from your hard drive or computer manufacturer if they have one available – it wouldn’t hurt to try both). If it fails the test, replace it. If it passes the test, then there's probably nothing wrong with it.

You can also test your RAM at http://www.memtest.org/. If it fails, test each chip individually to find those that are bad and replace them. If it passes, RAM is probably OK.


If that doesn't work (or you don’t have the disk), then I'm afraid the only option is a clean install. You can use Knoppix http://www.knopper.net/knoppix/index-en.html with a good ISO copier like: http://isorecorder.alexfeinman.com/isorecorder.htm along with a blank CD. This should give you enough access to the system (if you can't get in any other way though you should be able to do so through safe mode) to backup your important data. Once done, you can do a clean install either using the genuine Windows Vista Installation Disk or the Recovery Disk or the Recovery Partition (whatever process is dictated by your computer manufacturer – you may need to contact them for the procedure and perhaps to get recovery disks https://secure.tx.acer.com/RCDB/Main.aspx?brand=acer). To do a clean install proceed as follows: http://www.winsupersite.com/showcase/winvista_install_03.asp (adapted as necessary by the procedures of your computer manufacturer). Then you will need to re-install all your programs, reset all your preferences, reconfigure your network and email settings, restore your backed up data, run Windows Update with possibly nearly 150 updates pending,...
Hopefully one of these procedures will resolve or at least identify the cause of your problem if simply uninstalling Ubuntu didn't do the trick.

Good luck!
