Where to find the correct SHA1 checksum for the upgrade Pro Windows 8 ISO?

I ordered the Windows 8 Pro upgrade online.  (not a preview but the new product on 26/10/12).  I downloaded and burned the ISO of the English version of the Windows 8 ISO file.  I'm assuming that 64-bit. This took place without incident.  I started the upgrade on a PC running Windows 7 SP1 64-bit, but it failed during the installation phase of Windows 8 to 72% with the error "installing Windows 8 failed".

So I restarted the upgrade and it has not exactly in the same place (72%) and the same cryptic error.
So I contacted the Microsoft Store and they helped me to go through the process of downloading a 2nd time.  The 2nd ISO file was exactly the same size, BUT it had a different SHA1 checksum!
Then I tried the upgrade using the new DVD burned in the 2nd ISO file and it failed at exactly at the same stage of the upgrade (72%).
So I got two corrupt downloads / Burns?   I have no way to tell because all I know is that they have different amounts of control.
Maybe they all are both wrong, or maybe the question is something else entirely.
But first things first.   How can I determine if my ISO file is correct?
What is the checksum SHA1 of a non-corrupt ISO file?    Where to find the information online?

I have the same problem with my 64-bit windows English version.

I created a bootable DVD from iso and started to install a clean install by formatting the hard drive.
Installation will be stuck at 17% and it happened to me like 3 times and I burned a fresh DVD and always the same question.
It's like the worst level ever... Is there a way I can download an iso of 64-bit bootable DVD and use it to upgrade?

    Hello

    It's what you essentially have is a new installation or resumption of the plant and because your a single key is damaged, your only option would be to buy the discs or USB Drive Lenovo's.

    I don't think they said have you need a new license, you do not have.

    What you need are the disks that will essentially perform the function of a key...

    It varies depending on the manufacturer, but the game runs normally around US $20...

    However, it is not a new license. A new license would be a lot more money...

    He's using you current license... just reinstall your original configuration.

  • Where to find the key of Windows 8 on DVD Lenovo?

    Hello!

    Recently, I had problem with booting and installing Windows 8 via the Lenovo installation DVD. I downloaded Windows 8 Microsoft Official site and created the bootable USB key.

    My Windows 8 is still not activated, because I can't find the key on the cover of the DVD or DVD itself. I only got the number P/N on DVD.

    How to find a key on my Lenovo Win8 DVD's? Maybe it is recorded somewhere inside files on DVD?

    Any help appreciated.

    I found out I got the DVD, Lenovo were only Windows 8 drivers and no OS. Therefore, there is no KEY to be found.

  • Satellite L350 - where to find the latest driver for graphics card?

    I have a Satellite L350.
    I installed a game (EVE online) and it works as it should; However when I use alt - tab, the game crashes.
    It is not supposed to do this, and on the other PC it does not crash.

    I contacted the technical support for the game itself, and after reading my dxdiag, they concluded that it was because my drivers are up to date.

    They said specifically the graphics and audio drivers are the cause of the problem.
    I have a Mobile Intel (r) 4 series express chipset family graphics card, and the driver is dated 06/12/2008.
    my sound card is realtek audio and is dated 11/02/2006.
    I tried to update the graphics card on the site of intel, but the program tells me the installation was not validated for this computer and I had to contact the manufacturer.

    Anyone know where to find the updates compatible with computers laptop toshiba?

    Yours sincerely,
    LTA

    Hello trouble

    Please remember you have laptop and not of office. What you have done is just and it will help with the office, but on laptops, the situation is very different.
    Graphics card is suitable for the use of the laptop by Toshiba and downloaded driver from the manufacturer of the graphics card can not be installed.

    As you know probably common problem with laptops is heat and temperature of the material must be controlled. Graphics card too high temperature can ends with overheating and book cut or damage the equipment. Toshiba laptop to protect material must ensure on the pilots and don t allow to run on the limit.

    I must also say that your laptop is not game machine.

    Currently, there is no Windows 8 driver for mobile phone Pantech Renue P6030.  However, I download pictures from a Pantech Renue by connecting the mobile phone to a computer with Windows 8.  On the phone screen a menu popped up.  I chose mass storage link that connected to the computer, File Explorer.  From there, I did some limited tasks which enabled me to copy the images on my cloud.  Not all features are on the Explorer of files to allow downloading of all the pictures, but accomplished most of the tasks I wanted to finish.

  • Where to find the files for the integration of custom symbol sym.

    Hello

    I would add a Schottky diode personalized my Multisim 11.0 schematic. I would use the Schottky diode symbol and don't know where to find the adequate .sym file. Is there a database of these files? Of course, another option would be to do it myself. However, I would be nice to know how to extract the .sym files existing symbols in Multisim.

    Thank you.

    Kind regards

    Viktar

    Hello

    There is not a database with .sym files. However, you can take one of the symbols of control of databases and modify (if needed). Use the Component Wizard in Multisim to create your Schottky diode custom, when Multisim asks that you to the symbol information select copy of DB; in the Master database access Group of Diodes, Family SCHOTTKY_DIODE and select the most appropriate symbol, click OK. If you need to change this symbol just click change to open the symbol editor.

    Kind regards

  • Satellite L500-1DT - where to find the audio driver?

    Just reformat the laptop, went from windows 7 64 bit for windows 7 32 bit. Reformatted the disk that came with the laptop. I have no sound at all, the sound worked perfectly before and it keeps saying that I have no sound card. I tried to install the audio drivers but I can't find the right on the site with my model.

    I have a satellite L500-1DT with model PSLSOE.

    Tried to install the drivers available and I just get an application error after installation

    no idea how to fix it or where to find the correct drivers?

    Thank you

    Hey Buddy,

    To be honest I n don't know what problems you have with the driver audio but that's in the right place for all drivers:
    http://EU.computers.Toshiba-Europe.com > support & downloads > download drivers
    Laptop > Satellite > Satellite L Series > Satellite L500 > PSLS0E

    But before installing the latest version, remove the current version first and clean the registry with CCleaner
