Windows 7 install hangs at 35 percent

I upgraded to Vista Home Premium on the last stage of that Windows 7 hangs just at 35%

Help please.

Tips for solving common problems when Windows 7 won't install troubleshooting

1. start Windows Upgrade Advisor to see if there are known issues that might affect the installation and correct them.
http://Windows.Microsoft.com/en-us/Windows/downloads/Upgrade-Advisor

2 disable any security software: anti-virus, firewall etc. Don't forget to activate the Afterwords.
3. make sure that your computer has the latest drivers and BIOS. Update of the BIOS can be risky, don't do that if nothing else works.
4. disconnect all external devices except the keyboard and mouse before installing.
5. If using a video card and the computer has integrated video use and remove the video card.
6 unplug the computer from the internet, if you have wireless disable.
7. RAM (memory) - reduce the amount of RAM. 1 GB if 32-bit installation, 2 GB for 64-bit, then replace RAM if the upgrade was successful. If you added new RAM make sure it is also compatible.
8. If you have several hard drives remove all except the one that you install Windows 7, and then replace it after Windows 7 is installed.
9. If you have downloaded Windows 7 and it burned a DVD test burn again at the slowest speed possible. It is also possible the download may have errors, you can try to download it again.
10. If you click 'Upgrade' to start the installation make sure that you take a supported upgrade path. You can't make a room upgrade: A) XP to Windows 7, B) changing bit type ex: 32 to 64-bit C) change the languages, D) decommissioning editions ex: Vista of the month last 7 Pro, or E) Vista Home Pro 7.

11 turn off startup programs:
(A) click Start, type MSCONFIG in the search box and press ENTER.
OK the authorization of user account control and password if necessary
If you are using XP: click Start, run, and type: MSCONFIG and click OK.
(B) on the general tab, click Selective startup.
(C) just below the selective startup, clear the checkbox "Load Startup items".
(D) click the Services tab, check "Hide all Microsoft Services", and then click Disable all.
(E) click OK, and then restart the computer.
(F) try the upgrade again.

(NOTE: If the upgrade fails and you continue to use your rear security software, then also go back into MSCONFIG and under the general Tower XP/Vista tab, click "Normal startup", and then click OK to exit.)

12. check your RAM (memory) to find errors. Can take a long time, don't make that if nothing else has worked.
(A) Insert the Windows 7 DVD and restart the computer.
(B) start from the Windows 7 DVD.
(C) select your language, and then click Next.
(D) click on "repair your computer" then select the operating system to fix it.
(E) click on the link of the Memory Diagnostics in the system recovery menu.
(F) the computer will restart and your memory is checked for errors.

  • Windows 7 install hangs at 89% during the expansion stage of files

    I searched the Internet for the same problem and I can't find a definitive solution or cause for this.  It must be the worst installation experience ever!

    I have a 9 year old office computer running Windows XP Pro with SP3.  The specifications are the following:
    Processor 2.0 GHz of AMD Athlon 64 (32-bit)
    3 GB RAM
    1 GB videocard ATI (Radeon HD4650)
    200 GB IDE drive (SATA drive died a year ago)
    Sony DVD - RW drive
    There is no floppy drive on this desktop computer

    I decided to do a clean install of Windows 7 on it, I could test VS2012 and office 2013.  I installed the Windows 7 Upgrade Advisor and everything checked very well for compatibility.  I have downloaded Win 7 Ultimate x 86 with SP1 from the MSDN site, formatted the drive and installation.  He stopped at 0% a couple of times saying: "Windows cannot install required files. The file may be corrupted or missing.  Make sure all files required for installation are available. and run the Setup again.  Error code 0 x 80070015. »

    Then I downloaded Windows 7 Ultimate x 86 and burned another DVD with verification.  I tried with this.  Formatted the drive, deleted the partition, created a new partition and created the 100 MB system partition.  This time he went to 89% before launching the same error: "Windows cannot install required files. The file may be corrupted or missing.  Make sure all files required for installation are available. and run the Setup again.  Error code 0 x 80070015. "It does not get stuck at 89%, it reached 89%, stays there for a minute and then this error message.

    I gave up and I'm back to install Win XP on it, which took place without a hitch.  What is it?  Too old hardware?  Therefore, shouldn't the Upgrade Advisor say before you say it's just good install Windows 7?

    Hello

    Welcome to the community Microsoft and thanks for posting the question.

    According to the description provided, you have problems with the Installation of Windows 7 with error code 0 x 80070015.

    Error code 0 x 80070015 refers to a device not ready which would normally be on the DVD player.

    It is perhaps simply that the installation DVD is corrupt somehow or that the download of the. ISO is defective somehow. Worst case would be a material faullt.

    You can try to re-burning at 1 x speed to fork the best chance to burn correctly, or maybe upload again.

    If it is an option for you, the other options are the use of a USB key to install from-

  • Clean Windows 7 install hangs during expanding windows files

    well, so that's what I've done so far, I have downloaded the kit of the student digital river, I originally ran Windows xp 32-bit, so when I ran first the exe download, it gave me the error of not being able to record in a single folder to read and what not, but I followed the suggestions on the forums to move forward a burn on a startup disk expandedsetup folder in converting it to an iso, which I did, I installed the first time but missed the option to format my hard drive so my old files were still there, however, once got installed win 7 I wasn't able to connect to internet for some strange reason and I couldn't understand it, so I decided to take the 3 files I downloaded originally from digital river and try their unpacking on the 64 bit OS now I had installed, it worked fine this time without any errors, so I moved the folder expandedsetup to my laptop and he burned them on a dvd as before, this time I boot from the dvd and do a clean install, it installs again very well, but once I login in the OS and I am getting started with things once again everything is grinding the long, I tried to restart and it does not work, this time it froze just a black before the paper screen, so once more, I started from the dvd and tried to do a clean install, but this time, he begins to hang during the part of expanding windows files, so I decide to make another disc using the second expandedsetup folder thinking that perhaps a new one was a bad burn, this does not work either, it takes about 14% of full on the extension of the windows files and then he told me that the files is not found, so I tried the second drive once again, we only got 4% until it gives me error on files is not found , so I put the first early in and try and suspension 4% right now and I expect to give me the same error, I have really no idea of happening, there are too many variables, but I tried to evaluate each of them, would be - this related material? my computer is compatible for win 7 64 bit, I ran the Upgrade Advisor before you buy, so I know that my hardware can run it, I think it's my dvd drive or the hard drive, but they both seem to run fine otherwise, any help would be appreciated

    Hello Impoc,

    Thanks for posting on the Community Forums of Microsoft Vista.

    Installation may stop if the system cannot copy files. Here are some possible causes and solutions for this problem:

    ·     Your Windows installation disc is scratched, smudged, or dirty. Clean the disc with a soft cloth, insert it in the CD or DVD drive, and then start the Windows installation again. If your installation disc is damaged, you may need to replace it. For more information, go to How to replace Microsoft software or hardware lost, broken or missing on the Microsoft Web site.

    ·     Your CD-ROM or DVD drive is not working properly or the disk might be vibrating too much for the laser correctly read data. For more information about this problem, see your hardware documentation or contact the manufacturer of the CD or DVD drive.

    ·     If your computer has multiple CD or DVD drives, your computer may attempt to locate files on the wrong drive. If your computer has a feature to disable CD or DVD drives that are not used, turn off readers that you don't use. Otherwise, try to insert the disc in a different drive, and then restart the installation.

    ·     There is a virus on your computer. Run an antivirus program to scan your system and to identify the necessary repairs. Don't forget to disable the antivirus before you start the installation again.

    Also, it is usually caused by hardware or software that is not compatible with Windows 7. If you have this problem, follow these steps:

    1. wait 10 minutes to see if the installation continues. Look at the led on the hard drive (often a small light on your computer that blinks when your hard drive is running) to see if there is no activity. If your hard drive seems to be working, the installation must be current. If your hard disk doesn't seem to work, go to step 2.

    2. If the installation fails again, it may be a hardware incompatibility problem. Go to the Windows Upgrade Advisor on the Microsoft website to see if your computer can run Windows 7.

    3. If you have compatible hardware and your computer still stops responding, disable any unnecessary hardware. Remove (USB) universal serial bus devices. Remove or disable network cards, sound cards and cards of the series; and then restart the installation.

    If you have more than 1 Memory stick on your computer, try to remove all but one RAM stick and try to install Windows 7.

    If the computer still stops responding during installation, you may need to contact your computer manufacturer or retailer to check if the computer is compatible with Windows 7.

    Also check out the link below to learn more about solving Windows installation problems:
    http://Windows.Microsoft.com/en-us/Windows-Vista/troubleshoot-Windows-installation-problems

    Note: This article is related to Windows Vista. However, you can follow the same steps with Windows 7.

    If the installation fails after following the steps above, try to note the exact error message and provide the same.

    It will be useful.

  • Windows 7 install hangs at files step 21% 3.

    I'm trying to upgrade to Windows 7 from Windows Vista SP2.  The high-grade crashes at 21% of stage 3 (extension of files).
    I did the following: uninstalled my Norton 360 Security software.
    Chkdsk /r conducted and found no disk error.
    A ran memory diagnosis, and he reported no problems.
    Windows 7 Upgrade Advisor and uninstalled all the software and devices according to the guidelines.  The system hung twice in the same place.  I use a computer TechAdvance system with processors dual 2.66 GHZ on an Intel 965DH Mother board with 4 GB of memory and two hard drives.  The boot hard drive has 76 GB of available disk space.  A that someone has had this problem and solved?

    I started this thread and wanted to complete what has occurred.  With the help of Microsoft reps tech I was finally able to install windows 7 upgrade to windows vista.  In the startup journal, Microsoft tech rep isolated oem drivers in my inf file in windows that don't migrate.  We removed the oem drivers, after their record in a file on my desk just in case.  We then went to msconfig and made a selective startup, turning off all non-microsoft services.  We also had to rename the two files on windows put there by my first upgrade attempt, which failed, $UPGRADE ~ OS and $WINDOWS ~ BT by adding old to them so that the next upgrade attempt would not access.  We started the new facility at 1730 m 31 October, finally the 0800 on November 1, the upgrade is complete.  Now, I had almost half a million files and many programs on my computer that had to be collected and processed.  The section of "Expanding Windows Files" step 3 remained on 21% after the first reboot of windows 7 during approximately 8 hours, suggesting he was hooked, but it was not, I let the system run all night, and voila, when I got up the next morning at 7:30 she had completed all five stages and was the starter in the new windows 7.  It went fast, and from 08:00 it was running in windows 7 normally.  In addition, my Norton 360 v 3.0 security system, which I had uninstalled for the upgrade to Windows 7, reinstalled with incredible speed.  I was impressed and continued to test all the different programs and devices on my system and they work all well, and Windows 7 is faster than Windows Vista.
    Even if it took 15 hours to install, I'm so happy with the results.

  • Explorer Windows began to hang occasionally after installation of recent updates

    I installed the latest Windows updates two days ago. After that, I observed the strange question. Explorer Windows or any other application that bed the list of logical drives crashes from time to time for 10-15 minutes and does not respond. If I wait until he wakes up, he continues to work normally, but may crash again after some time. Sometimes, it may be in 10-20 minutes after the restart, or even in 1-2 hours after the reboot. The Task Manager shows not overloading CPU or memory for blocking.

    My OS is Vista Home Premium x 64 SP1 computer HP Pavilion DV7 laptop, Intel Core Duo 2 GHz, 4 GB RAM, HARD 2 x 250 GB drive.

    I completed the virus scan, tried to uninstall antivirus and any other software that can theoretically cause hang while reading list of reader, nothing done. Test memory not found error. Also done sfc/scannow. My hardware drivers are installed, Device Manager shows all the hardware without error in factory work. Event log contains no errors. The total number of windows updates installed the same day is about 60, I can provide the full list if necessary.

    Any ideas or suggestions?

    Can I download this, free preference?

    Hello

    How have you noticed that an invalid Windows XP installed?

    Usually if you reinstall your laptop with Toshiba recovery disk it s a copy valid XP is already activated and there is nothing to do.

    In addition, the product key on the lower side of your laptop belongs to the preinstalled version of Windows XP and t can be used with the other XP discs.

    "installation of windows: is impossible to complete the installation." to install windows on the pc restart installation.

    If I press 'ok' this message returns and the same thing with the 'X '.

    What can I do?

    Thank you

    OK, so let me correct me on the tools.

    You will need another Windows computer with an internet connection, a 8 GB USB key.

    Your Pavilion x 2 has already a normal USB port, so you don't have an OTG adapter or an external keyboard.

    On another Windows machine (laptop or desktop), you will need to install the Microsoft Media creation tool. Download 32 bit or 64 bit to match the other PC you borrow to make USB install drive with.

    Windows media 10 creation tools

    Once installed, launch it. When it opens, follow these steps:

    Choose "Create install to another PC media" and click Next.

    Select the desired language. Select Windows 10 House. Architecture, choose 32-bit (x 86) and click Next.

    Select a USB flash drive and click Next.

    Make sure that the correct drive letter is selected for your USB Thumb drive. He will probably want to name ESD - USB by default, and it's ok. Click Next.

    It will start to download Windows 10 and create the version installed on the USB key.

    Now that your installation drive is made, you can use it to install Windows 10 on x 2 flag.

    Makes sure that your battery is fully charged and the power is connected.

    Insert the installation disk USB that you just created in the USB port.

    Make sure that no other things aren't connected except the USB thumb drive, mouse cable and power.

    Turn on the Tablet and quickly start pressing the ESCAPE key to bring up the Start Menu in the Bios.

    Select F9 for Boot Device Options.

    The TOP or bottom of the arrows on the keyboard to select the USB.

    The USB key can start the installation or might open a window asking how to make the recovery. If so, select the program in the media.

    NOTE: IF the USB is not an option to select, you need to go back into the Bios and disable Secure Boot and / or also to activate Legacy Boot. Here, the link to the instructions for it and it will be the same for almost all HP computers.

    How to disable Secure Boot

    Once that Windows is installed, you will be asked to enter an activation key to continue.

    Choose to ignore this and allow the installation to continue. When Windows finally installed it can ask you again the key.

    Pass it again and let Windows update or force it to be updated manually. When it updates, it will be activated automatically. It will because you already had 10 Windows updated, work and previously enabled on this computer.

    If all goes well, I didn't confuse you again. Let me know if you have any other questions.

    Hello Lara.

    IF you have updated from 8 to 8.1 and the process was interrupted during installation, this may damage the disc and therefore locked error. "Refreshing" the system would not be the answer that you need to clean install Windows 8 again. 8.1 update can break the bond of the recovery partition, especially if it has become corrupted as indicated.

    You must clean up the installation with the recovery discs, you must have created before you updated to 8.1.

    In addition, if you do not have the recovery disks, you can buy a set of HP or install a regular copy of Windows 8 and then update the drivers manually. HP has the Windows key now integrated into the bios.

    Hello

    I have a problem with my newly purchased 1hd U500 laptop. I didn't like the way the Manager auto partitioned hard drive, so I went ahead and all the formatted partitions and divide them according to my needs. The problem is that the laptop, even if it came with Windows 7 Home Premium 64-bit, had no Windows 7 install cd/dvd or any other ultility cd/dvd. I went and downloaded a copy of Windows 7 Home Premium 64 - bit Microsoft MSDNA, installed, but when I try to activate it using the cd - key on the sticker on the back of the laptop, it says invalid cd - key.

    I rechecked the cd - key, and I wrote it down correctly. It says on the sticker Windows 7 Home Prem OA. Do I need a special kit of Win7 or something?
