Windows 7 fail to boot after ubuntu installation

Q: Windows 7 fail to boot after ubuntu installation

I've installed Ubuntu 11.04 on my notebook ASUS U36SD. It worked perfectly fine for 4 months.
Recently, I decided to install the last version of Ubuntu, 11.11. From now, Windows 7 doen't want to boot: It freezes at the boot screen. I tried to use the repair mode, but it failed. I also tried the safe mode. It still does't boot and freeze when loading CLASSPNP.SYS.

Please, do you have an idea about how to solve this problem?

Preferred Solution: Windows 7 fail to boot after ubuntu installation

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Windows 7 fail to boot after ubuntu installation

After an installation of ubuntu, my C: partition, where Windows 7 is installed is corrupted.
From linux, I can read it and access the disk, but the windows recovery environment doen't detect it.

I think that it is because my partition is also hidden (0x17)
Do you know how to unhide this partition from linux, or to make a chkdsk on it from the recovery environment?

I tried to install Ubuntu on my Lenovo y580 and things didn't go as planed. It is the first time I am dealing with Ubuntu and partitions so I'm quite lost. I have Windows 7 Home premium 64 bit.

In short:

I deleted Ubuntu but windows doesn't boot. I have windows recovery dvd and Lenovo system recovery dvds. I tried bootup repair, but it says, it cannot repair. The errors are: 6.1.7600.16385, MissingOsLoader
I also tried different commands in cmd: bootrec.exe/FixBoot , bootrec.exe/FixMbr , bootrec.exe/RebuildMcd ,
I also cannot come to safe mode boot option.

Long description of what I did:

The laptop comes with 1Tb hard drive and small 32Gb ssd for caching and system. Since the system already had 4 partitions, I deleted the partition which is meant as a back up partition and I also shrank the storage partition -> got 2 pieces of undedicated space. Before that I made recovery discs and windows repair dvd. Sadly, didn't make a restore point.

Then I installed Ubuntu using LiveUsb. There was no option (in installation process) to install it alongside Windows, so I created new partition. Everything installed nicely but after that I could not boot Ubuntu. The computer booted straight to Windows. So I used Ubuntu boot repair. After that I could boot Ubuntu, but I couldn't boot windows. Than I used Ubuntu boot repair once more (I saw somewhere that it should help), but didn't help.

In the next step I deleted Ubuntu using Ubuntu os uninstaller and I also deleted the p... Read more

A:Failed ubuntu installation, windows won't boot

From what I've read it sounds like the grub boot selector didn't come with Ubuntu. When I installed Ubuntu along windows it automatically came with a loader so you could select what one to boot,
Now to get this straight, were the two OS's on the same drive and separated by partitions, or are they on separate drives?

I have two hard drives on my computer, one for my OS and apps (C, and one for my data (D. I recently reformatted my C: drive, re-installing Windows 7. I want to set up a dual-boot system with Ubuntu 10.04.

The problem I am having is that the Ubuntu installer recognizes my D: drive but not the C:. The C: drive is currently partitioned as follows:

100 MB NTFS Primary System Reserved
449.59 GB NTFS Primary
146.48 GB Unallocated

I have searched all over the net for answers, but none of the solutions I have found work.

Any thoughts?

A:Can't Get a Dual-Boot Windows 7/Ubuntu Installation Going

You say, you have two HD Drive, therefore you have a Disk0 & a Disk1.

When installing Linux
1) Remove Disk0 with Windows 7.
2) Install Linux to Disk1
3) Replace Disk0.
4) Use the one time boot menu to boot the OS's.

A:Windows XP boot failure after Ubuntu linux installation


Media Center (MCE) is a variation of XP Pro.

I'm not even sure that you could use an XP Pro version to "recover" an XP MCE system, since I thought that all those systems utilize recovery partitions/CDs which have been prepared by the manufacturer of the system.

These recovery/restore CDs/partitions...are not the same as an XP install CD, since they contain programs, drivers, and other modifications which might have been put in by the manufacturer.

I could be wrong.

Please help, I was trying to install ubuntu alongside windows 10 on my custom desktop. During installation I chose the "install ubuntu alongside windows 10 option". The next option was to select drive and allocate drive space. I chose the were Windows 10 was installed, and distributed the disk space equally for both windows and ubuntu. Later, I pressed continue, it started to process and it gave me a fail message which I can't remember which one. Later, it was late at night so I decided to try installation next day. Next day I booted my pc and windows was gone from the boot manager. This seemed strange as I never got to commence ubuntu installation, I assumed my boot manager was broken. I tried repair my pc option, I tried command prompts that can fix the boot manager that I found searching online, nothing fixed it. I took my pc to a repair shop and they told me my windows partition was deleted. This seemed so strange, how can I have deleted my windows partition if I never fully installed Ubuntu in the first place? I don't have Ubuntu installed on my computer. I chose the "install ubuntu alongside Windows" option which permits dual-boot. Did I actually deleted it and I have to reinstall it? What can I do? Please help

A:HELP Failed Ubuntu dual boot installation deleted windows

You should have gone into Disk Management in Windows 10 and created a second partition on the hard drive, then installed Ubuntu in that second partition.
It looks like you tried to install Ubuntu in the same partition that Windows 10 was installed in, and wiped it out.

Hi All.
I'm running Vista HP 64x and Ubuntu 7.10 64x in a dual boot setup.
Currently I have an nVidia 8600GT but would like to upgrade to an 8800GT.
However the dual boot is causing me a problem.
NVidia forums advise me to boot Vista into safe mode, uninstall the 8600 drivers, run drivercleaner, swap the cards and then install the appropriate drivers from their website.
The problem is that since installing Ubuntu I no longer have a safe mode option in my boot menu. It has Ubuntu, ubuntu recovery mode, memtest, and then Vista/Longhorn. There is no safe mode option.
I can get into setup and BIOS (del,tab) and have looked in there but I'm not very techy and cannot understand it. There doesn't seem to be any mention of Vista after the initial choice.

Can anybody help me with some simple instructions? I want to upgrade the card to improve my gaming experience but it's proving complicated.
Do I really need to be in safe mode? If so does anyone know how I can boot into it?

Thanks in advance, John

No real need to do it from safemode unless you have problems, TBH I wouldn't even both to uninstall the old drivers (but thats not good practice)

1 Uninstall the old drivers.
2 Switch the PC off & swap the cards.
3 Start PC and install latest drivers from the nvidia website.

Thats all you need to do.

I purchased this laptop through an auction my Nephew's company holds when they upgrade their computers about 3 years ago. I downloaded Ubuntu 15.04 on it which worked great. Recently I decided to try a different version of Ubuntu (Lubuntu) instead of just upgrading to 16.04. After 6 months I decided I did not like it and tried to go back to regular Ubuntu, upgrading to 16.04.  During the installation, the process got hung up about 3/4 of the way through and refused to go any farther so I shut the system down and downloaded another USB copy of the U 16.04 OS from a different computer. When I tried to install the OS I was confronted with a request for passwords. The passwords I had on the machine would not work for the bios, the boot options or anything else. Have I turned my nice laptop into a big paperweight? Thank you in advance for any help you can give me. UncleWiggily195

Windows could not start because the following file is missing or corrupt:
<Windows Root>\System 32\ntoskrnl.exe
Please re-install a copy of the above file.

To get the Win 7 working again I have to to a Windows 7 startup repair.

Well it failed like midway through, and now it wont even boot the windows seven CD only tries to do startup repair every time it starts up. I do have access to the other tools if i cancel the startup repair which says it continuously fails. Is there a way to fix this without loosing all her files?

Today I had 15 important updates waiting for me on Windows 8.1 so I decided to run them. After downloading the updates it asks to restart the PC.

I got to the startup screen with the blue windows logo and the white dots circle spinning around. Then the "Updating your system (..%)" message appeared. But then, I got the following message:

Fatal Error C00000B5 applying update operation 155 of 30953 (SMCon...)

The white dots circle keeps spinning but the message was stuck at this. So I decided to reboot.

It did the normal boot checks... memory checks... hard drive checks... DMI Pool checks... etc as its supposed to normally, but instead of going to the windows startup screen I got the following....

Blue Screen:
Your PC couldn't start properly.
There isn't enough memory available to create a ramdisk device.

Error Code: 0xC0000017

Press Enter to try again
Press F8 for Startup Settings

This is a very strange message since I have 20GB of RAM and the memory check in the BIOS was fine indicating the 20GB present. So there is enough RAM for it to do whatever it needs to do.

I pressed Enter and then got the same Fatal Error C00000B5 after it tried to install the updates again.
I rebooted again and entered F8 and tried to enter Safe Mode, but it tries to install the updates even when trying to enter Safe Mode also and then fails. So I am stuck and cannot get into the PC.

I got an old computer from a friend that wasn't using it anymore. Right now it has Windows XP, and I want to install Ubuntu on it, but pushing any of the listed buttons on start up results in the screen going black and not responding to anything for at least a whole day (at which point I gave up and turned it off). It's an HP Compaq d220 MT and comes up and says <[TAB] to post screen> <F9 = Boot Menu> <F10 = Setup> <F12 = Network Service Boot>. My friend already got all the info off the computer he needs, I got new RAM for it as he wanted to keep what was in it, and almost everything works fine. Unfortunately, he has nothing that came with the computer, no cds, manuals, or anything, and he can't even remember the administrator password. I have a boot cd for the Ubuntu version I've read will work on this computer, but I can't for the life of me figure out what to try next.

This has happened to me with two computers now.
I start with windows on the hard drive. Download all drivers and set everything up. Next I install Ubuntu on a serparate ext3 partition and set everything up with that and it works great. When I get into the grub loader, and try to select windows, the windows will begin to load, but right as it is about to get into the login screen a bsod flashes quickly and it restarts. It isn't my disks because the first comp was winxp and linux 8 and the second comp (the one I'm more concerned about) is vista and 10.04. Can't get into safe mode either.

Any idea how to fix this? I'd hate to spend another 2 hours reinstalling windows and drivers. I would just use linux exclusively but I need solidworks, autocad, and starcraft II.

I just got my Windows 7 (64-bit) Home Premium disk on Friday. Yesterday I got a brand new 1TB Seagate HDD to run it.

First I installed the hard drive and booted on my original 500 GB drive running Windows XP (32 bit). From there I formatted the new drive and then rebooted from the Windows 7 install disk.

The install process seems to be going fine until it gets to the last step, "Completing Installation", and the system locks up. Upon restarting I get the screen to start Windows in safe mode, but then I get a notification that I can't start in safe mode until the installation has been completed. The system restarts and gets to the Windows logo/load screen and then the screen goes black and freezes there.

I rebooted from the CD again and tried to do a repair install but got the message that it was unable to repair automatically. It referenced problem signatures 6.1.7600.16385 and 474.

I've run memtest and chkdsk and found no problems. I've also run the Windows 7 Upgrade Advisor and that found no problems.

My hardware profile:
Asus P5N-D Motherboard
Intel Core2 Quad 2.66 ghz
4 gb of Corsair ram

Well, I decided to try to triple boot my mac and I was met by a world of frustration and the need to chain smoke.

I had OSX and Windows 7 Ultimate via bootcamp installed and working wonderfully. I tried to install ubuntu and the keyboard didn't work in the grub menu along with a slew of other difficulties, so I decided just to kick back to OSX and Windows and lose Ubuntu. What happened is I started receiving the dreaded "Unknown Device String" error upon my trying to boot windows from bootcamp. I tried troubleshooting, and my only results were different errors in the same stage of booting, and blah blah blah... I tried a ton of different ways to repair windows mbr and and some other things, but I've decided to forget trying to fix the boot process.

What I'd like to do is create an image of my windows OS, minus the boot settings of course :) but since I can't access my windows OS, I've got to either do it from OSX or ubuntu. I'd then like to reinstall windows, and restore the OS I currently have. Is it possible? Any thoughts? Thanks for any input guys!

The computer goes blank right after Windows starts up as it's supposed to go to the login screen, and the cursor was the only thing to appear. My answer to everything is to basically reinstall Windows 7 and start over, but after inserting the disc, begining the installation, and going through most of the motions....after Windows restarts again the screen goes black. Before I tried to reinstall Windows I was able to use the computer in Safe Mode, but after the reinstallation failed I can't reach safe mode. I can't seem to find a way to finish the installation.

If the original issue is caused by a registry error, you might be able to replace the corrupted registry hive files from the backup copy. Usually Windows will keep a backup copy inside "C:\Windows\System32\Config\Regback" folder. I would suggest carefully reading the below tutorial which covers step by step instructions on how to do the registry restore.

Hi a couple of months ago my system crashed, windows 7 wouldnt boot, and I misplaced my installation disk. I had the problems several times since obtaining the computer several years ago. (Lenovo IDeaPad y450). I attributed the problem to what I believed was a bad hard disk, so I replaced it with a refurbished model.
I installed Ubungu 13.10, and it worked well ever since. I later located my win 7 disk and created a dual boot. Windows worked very well for several months until it stopped starting up last week. It would get to the black windows screen, where it says starting, and usually get stuck there. I would get fed up and turn it off after half an hour. Once it was as the screen and it later started the checkdisk program and found no errors. Another time it finally got into windows after a very long loading time, and it seemed to work fine, until the next time I restarted windows. It just went back to the loading windows screen.
I formatted the windows partition through GParted in Ubuntu, and tried the installation disk, and it would get stuck at 0% in the "expanding files" sequence. After an hour of hoping something would happen I got fed up and forced it off again.
Not sure what to do from this point. I have read other posts and it has led me to think that the issue could possibly be bad RAM or an issue with BIOS. But, Ubuntu has been working fine, while Windows has simply been freezing at any attempt of a startup.

A:Win 7 , Ubuntu dual boot, windows wont boot, startup disk doesnt help

It could be that the HDD has a bad sector in the Windows partition, or that the drive is actually failing. If there is a utility in Linux that tests memory, I would run it.

You could also use Memtest86+. It runs from a CD/DVD. Let it run for several passes to rule out bad RAM.

I wanted to set up Ubuntu on my computer, and followed the instructions in the first answer to this thread: dual boot - How to install Ubuntu alongside Windows 7/8 - Ask Ubuntu

As instructed, I created a logical partition using EaseUS software. I did this on my H:/ drive, a hard disk drive (whereas Windows 7 was installed on C:, and SSD).

After a mandatory reboot for the new partition changes, I did not immediately go to install Ubuntu, although I had Live USB to do so. Instead, if I remember properly, I booted into Windows to make sure everything was OK, but only to find out that some "Windows could not boot properly", giving me the option to 'Launch Startup Repair' - which I did, but to no avail. All it did was reported that some 2 system files were missing or corrupt.

I then installed Ubuntu on a third drive because I still needed it to perform some benchmarking. I did this using the 'install alongside windows 7' option.
But now that I don't need Ubuntu anymore, all I am interested in is getting back to Windows, while keeping all the files and programs intact.

How should I go about fixing this? Delete the logical partition on the other drive? I also have that Windows installation CD, and I'm thinking its repair options could be useful - but not having a whole lot of self-confidence, I don't know what steps exactly to take to preserve my files.

Any help is greatly appreciated!

I recently had to rebuild the Window 7 Home Premium X64 on my Gateway NV59 laptop. I used the recovery CDs from Gateway to do this.

So all I currently have is the OS and applications that were reinstalled from these CDs except the Norton Antivirus which I uninstalled since I use McAfee. I have not installed the McAfee yet.

I have installed approximately 160 updates successfully. Unfortunately the following 3 updates continue to fail:
Security Update for Windows 7 for x64 (KB2676562)
Security Update for Windows 7 for x64 (KB2724197)
Windows 7 Service Pack 1 fo X64 (KB976932)

I even tried to install each seperately but had no success. I have attached the error message that I see when the installaton fails.

Any ideas as to why these will not install?

I've got a Dell Inspiron laptop with Windows Vista on that won't boot. The Windows loading screen appears but it never makes it to Windows.

I tried booting from a USB drive with Ubuntu on and it started but I get an error message saying the hard drive is about to fail and I should back up.

Any ideas what the problem might be and how likely is it the drive will fail?

Acer Desktop PC Model: AM1610
sis ethernet adapter
webstar dpx 2000 series cable modem

After setting up a dual boot system successfully,
Vista connects to internet via ethernet, Ubuntu does not.

sis ethernet driver is updated to latest version

I can access the internet from Ubuntu however, after shutting down the pc, unplugging the power cord, removing the cmos battery and reinstalling. I reinsert the power cord and boot up as normal into Ubuntu, and have full access to internet.

Simply removing/reinserting ethernet cord, removing/reinserting pc or cable modem power cord, or resetting cable modem, does not work.

I am asking if there is a solution as to where I can log off Vista and restart pc into Ubuntu and have internet access automatically, bypassing all these steps I've explained?

After perusing multiple forums where people have described similar if not same issues, I've yet to find a solution to this.

I ran ipconfig in Vista and have the results. I ran ifconfig in Ubuntu 9.10 and have the results.

As these results may contain information that can present a vulnerability regarding system/ip identification, I have omitted them here.

If needed, I will respond via personal message with the contents.

After deleting the partition on which Ubuntu was installed and enlarging the windows partition to fill the old space at the same time( stupid I know), I am unable to boot to Windows 7. All I see is a command line message that says Unknown File System and on the next line says Grub Rescue> with the option to input commands. After looking at this forum and Ubuntu forums I'm still unable to resolve the issue. I would like to be able to boot into windows 7.

Hi there,Recently got a HP Pavilion g6 2213sa which came with Windows 8 (spit!) and this disgusting UEFI BIOS replacement (double spit!).Anyway, I need to dual boot Ubuntu on my system, so I installed Ubuntu. Normally, on a non UEFI system, a "Grub" bootloader installed by Linux would take over the startup process, and allow you to choose between either Windows 8 or Ubuntu on startup. However, on this computer, startup is just booting straight to Windows 8 despite the fact that Ubuntu and Grub IS installed.Now, upon startup, if I press F9, then I get to change the boot-device on a one-time basis. I can either select "OS Boot Manager", which loads Windows 8, or "Ubuntu" which loads the Grub bootloader which allows me to select Windows 8 or Ubuntu.However, when I press F10 to enter the Bios Setup with the intention of changing the boot order permanently, the Ubuntu option isn't there. Instead it has OS Manager, USB Disk, CD Rom, USB CD Rom and Network Card.Thanks, HP for, the crappily designed BIOS.Anyway, can anyone PLEASE provide me a way of changing the boot order so that GRUB is loaded first and NOT this crap Windows 8 rubbish (that I would happily bin if I didn't need it for work).

Hi, all! First off, thanks for having these great forums here. Hopefully I can find the help I need here.

About two weeks ago, I got something like SecurityTool virus but not quite, and I got rid of it by heading over to safemode, reinstalling Malwarebytes, etc. Every time I had run Rkill, it launched the virus again, something I haven't seen before. Malwarebytes got rid of it, but I've had problems ever since. Today, I ran a full Malwarebytes, Housecall Antivirus, and Avast scan; the first two picked up nothing and the Avast picked up one trojan it classified as adware.

Every time I try to run Rkill, three cascading windows pop up saying "Installation failed." I'm kind of worried. Do you think something's wrong with my computer?

Oh, and for bonus head-desking... My bootup/startup menu thing doesn't work. The cmd thing. It doesn't exist anymore. Please, if anybody can help me out, that'd be great.

I recently installed Ubuntu 10.04 on my HP Mini 110-1116NR, then deleted the partitions that had Ubuntu on them, not knowing that Ubuntu comes with GRUB2, and sets itself as the default boot for that system. Now that GRUB2 is not installed, since it was on my only HDD, it looks for the GRUB2 partition, which does not exist, so I get an error on a command script that shows as follows:

"GRUB -error:no such partition
"grub rescue>

I still have Ubuntu on a flash drive. And I have my sister's computer to use until I get mine fixed, so I need help. I downloaded the Win7 Recovery Disc, but I don't have a program that can write the ISO image file to a USB flash drive, so I need to know how to get the ISO on the USB Drive, or how to fix the boot for Win7. I'm willing to do anything. lol. I've already done a couple hours worth of 'Google-ing' for how to fix this error and have come empty-handed. Please help.

I installed Ubuntu on the same hard drive as my Windows 7 (different partition ofcourse)

Now, even with windows boot manager, when I choose 'start windows' it writes 'windows is loading files' then reboots.

Can't use recovery options "repair your computer" off my windows cd since it keeps telling me I don't have the matching windows version (perhaps since ubuntu made some changes ro the MBR?).

Solutions I've tried:
1. Fixing MBR with a 'utility' boot-cd like hiren's. All it did was mess up ubuntu aswell so I had to reinstall ubuntu just to be able to boot.

2. Tried using boot-repair utility in Ubuntu - didn't work, same problem.

3. Tried burning rescue disc off an existing windows 7 computer. Same error - 'no matching windows found'

How can I reach window's rescue enviourment if it won't let me boot into it? I would try to use bootrec.exe but I can't get to it.

Please help? I really don't want to re-install windows 7 and lose all I have on that partition.

A:Windows won't boot after installing Ubuntu 14.04 for dual-boot.

First off, if you can boot into Ubuntu you can browse the Windows partition and copy your files to a USB HDD for backup, so you won't loose anything if you have to reinstall.
Then use EasyBCD boot manager to manage your OS's boot loader.

After having installed Ubuntu 16.04 on my Lenovo IdeaPad U430p I'm not able to start Windows anymore. When I installed Ubuntu I used the setup to divide my Windows partition in two parts. One is still used for Windows and the other part is used for Ubuntu. Whenever I select Windows in Grub or use the EFI boot menu and select Windows it immediately goes into startup repair mode. When using the command line of startup repair I can see that all my files that are on the Windows partition are still there and everything looks fine to me. But still, so far I haven't found a solution. I've tried the automatic startup repair. I have tried to fix it with the bootrec command and rebuilt the bcd, which was also unsuccessful. I also tried to activate the boot log but the log is not even created. It seems that the system directly goes into startup repair without even starting to boot into windows. I'm kind of lost and don't really know what I could do to fix this. Does anybody have an idea how to fix this? Cheers,Bastian

Hi there,

I've recently built a new rig and I've had continuous problems trying to boot. I have two HDDs and one SDD. It seems when the two HDDs are plugged in, i can sometimes boot ok, and most times i get:

Windows failed to start. A recent hardware or software change might be the cause.

Status: 0xc000000e

Boot selection failed because a required device is inaccessible


Please select a boot device, or something to the affect.

I've updated to the latest bios on my new mobo ( Gigabyte z97x SOC Force ) and ive done a fresh install of windows several times on the SDD. I also ran crystal disk to check health on the SDD and it came back healthy.

It seems mostly my boot problems are linked to plugging in the two other HDDs, though I've no idea why this would be, and how to fix it? Is it a motherboard problem or a HDD problem?

Any help greatly appreciated.

Ok I've searched and gone through multiple forum qestions that have been solved with similar problems as mine and nothing is working. My problem as of right now is when I go to update to service pack 3 by using windows update, I hit express, service pack 3 comes up and I click install updates and which point the install screen comes up, after about 30 seconds the install fails. I doth know where to go with this problem anymore. I've updated the .dll's I've scanned spyware and malware, deleted all temp files..... Some things have helped for example I downloaded and ran a registry fix which got some other updates to install through the repair that wouldn't install through windows update. And after I updated the dll's and deleted the files in the %temp% and c:\windows\temp folders other updates installed during shut down but service pack 3 is the only one giving me the problem now. Please help!!!!
