How to reinstall windows 8

So i recently scanned my laptop with windows defender and found a virus. I removed it but i would like to preform a clean scan to make sure that my computer doesn't have any malicious software.

There is no need to reinstall Windows 8
Just redo a full scan with Windows Defender
Then download Malwarebytes Free, not the trial version and do a full scan.
If both scans report nothing then you are clean.

How to reinstall windows 8 on bootcamp

how to reinstall windows 8 on bootcamp macbook pro, without losing anything on OS (Apple) side

Start Bootcamp Assistant then select the option to remove Windows and return your drive to a single partition. Once Windows is removed start Bootcamp Assistant again and select the option to install Windows. Follow the Bootcamp instructions for installing Windows.
This process will not cause lose of OSx data or applications if done correctly. But as allways, create a good backup of your data because things sometimes go wrong or instructions are not followed causing data lose.

How to reinstall Windows 8 on Yoga 13 with damaged Recovery Image?

I changed the partitions on my Yoga 13. Now it is not possible to refresh, reinstall or perform an advance start-up, as it looks like there is no recovery image anymore. The systems is currently very messy and needs a reinstall.
Can someone tell me how to reinstall Windows 8 on the Yoga 13 when the recovery image is lost or damaged?

hi Chevex,
Thanks for using Lenovo Community Forums!
In the event that the Recovery partition is not working the only option is to use the Recovery CD that you can create when you first got the computer.
but if you were not able to create a Recovery CD and the Onekey Recovery is not working.
You can get the Recovery CD from the Software Department (Fees may apply to the discs)
you can contact the Hardware Team again and ask to be transferred to Software team for purchasing RCD

Best to restore the hard disk to its original out-of-the-box contents using Toshiba recovery media. All the drivers and utilities are properly preinstalled. Windows is preactivated.
If you failed to burn recovery discs, you can obtain them from Toshiba. Scroll down to Get Recovery Media here.
For instructions, see the section Restoring from recovery DVDs/media, which begins on p. 70 of the User's Guide.

If the new hard disk uses advanced-format technology, be prepared to install a new storage driver first thing.

How to reinstall Windows 10

Hi, I have a laptop with Windows 8 in the factory image.I installed Windows 10 but had some issue with 3rd party softwares. It's a general question, not related to a laptop model. How to reinstall Windows 10 ? Do I need to put back the factory image ? It's seems the Windows 10 upgrade works only with Windows 8.1 With the factory image, the steps will be: -Restore the factory image
-Install all windows update in Windows 8.0 to get the Windows 8.1 update
-update drivers
-Install Windows 8.1
-Install all windows 8.1 update to get Windows 10-Install Windows 10
It's seems to be a very long process.
What's the recommended way to reinstall Windows 10 ?
Thanks

I don't want to do a clean. I don't want to install every driver. Is it possible to upgrade the Windows 8 factory image (not 8.1) directly to Windows 10, keeping all drivers ? There is 144 important update in Windows 8, only to have access to Windows 8.1 installation page in Windows store. I don't want to take one week to install Windows 10

Satellite A110 - How to reinstall Windows XP?

Hi,
I have a very serious problem. I had to format my hard drive, and now, I want to reinstall Windows XP OS on my machine. The serial key is written under my keyboard, but I don't know how to specify it during the installation process.
Can i write an email to Toshiba asking for a new DVD copy of the OS?
Thanks in advance.
Dani

Hi
Im a little bit confused now. Why do you want a new installation disk if you dont know how to use the product key on the bottom side?
Do you have a XP disk at the moment?
The product key on the bottom side of the notebook cant be used with a normal XP installation disk that you can buy in every computer shop. This is an OEM key and belongs to the preinstalled XP version.
So you can ask an authorized service provider for a new recovery disk or you buy a normal XP disk but then you have to use the product key that is delivered with the XP disk.

How to Reinstall Windows on Existing Bootcamp Partition

I've been running Windows 7 under Bootcamp on my 2011 MacBookPro. I've run into a situation where Windows7 will no longer install updates. I worked one day with Microsoft for over an hour but they could not find what was causing the problem. FYI, when looking into this problem, the error code that is produced is Error Code 8007010B. I have found nothing substantial online in regards to this code.
I've used Winclone (a Mac application) in the past without issues to restore a Boot Camp Windows partition. Since purchasing Winclone 3.4 I've made several backups, but now that I am actually trying to restore one of those backups I'm getting a message:
"the image you are attempting to restore does not contain the correct information".
So I am frustrated and have emailed twocanoes.com, the Winclone publisher and waiting for their answer.
Working with Bootcamp
I'm trying to figure out the steps I need to reinstall Windows from scratch in an existing bootcamp partition. Do I need to start from scratch with Bootcamp, or can I reinstall Windows from inside Windows? If I do the latter, how do I prompt Bootcamp to reinstall the Apple drivers?
Other Issues FYI
I'm having trouble locating the Windows 7 instal DVD I originally purchased. I do have the serial number. So I've downloaded a copy of Windows 7 from the MyDigitalLife Windows7 Repository.
I have burned the iso image to a DVD. I've got 2 versions, one is the .iso file burned onto the DVD, the other are the contents of the .iso file burned to DVD. I assume to install Windows, it will want the one with the contents of the Windows installer burned to it? Any other issues I may be unaware of regarding this kind of Windows install?
Is there any advantage of reinstalling Windows from a USB Flash drive as compared to a DVD? Just curious.
Finally, for Activation, because this copy of Windows is going back into the same Bootcamp partition on the same hardware, will I have to reactivate Windows? If so, suggestions appreciated.
Thanks!
-Dave

I appreciate the help. Can you tell me what are the steps to tell Bootcamp to install drivers into a Windows install? Thanks!
Update: I looked at the Bootcamp Assistant instructions and now I understand your answer. Info here:
"Step 4: Install the Windows support software
After installing Windows, install Mac drivers and other support software for Windows. The
support software installs Boot Camp drivers to support your Mac hardware, including AirPort
devices, the built-in camera, the Apple Remote, the trackpad on a portable Mac, and the function
keys on an Apple keyboard. The software also installs the Boot Camp control panel for Windows
and the Apple Boot Camp system tray item.
You can download the support software by selecting the “Download the latest Windows support
software from Apple” option in Boot Camp Assistant. The support software must be copied to a USB flash drive formatted in MS_DOS FAT. If the installer does not start automatically, doubleclick the setup.exe file in the Bootcamp folder."
If you or anyone have any other tips, they would be appreciated. As this appears to happen with Windows quite frequently, and I've had to do it multiple times over the years, I'm not looking forward to it.

How to reinstall Windows XP against Bootcamp for a Macbook

I am a new switcher for Mac OS. My major work has always been completed in XP OS. but recently I suffered a frequent down for XP OS. What should I do to reinstall a XP with Bootcamp?
1. My macbook was installed with old version of bootcamp, should I remove this older one and reinstall a new one?
2. How to remove bootcamp from a Mac OS?
Better provide me a detailed guide to secure this reinstallment.THANKS EVERYONE.

If you launch Boot Camp Assistant, you will see that one of the choices on the first screen is to "Restore the startup disk to a single volume". Click on that and follow the directions. That will remove Boot Camp and Windows XP from your Mac.
You can then launch Boot Camp Assistant again to reinstall Windows.
If what you are saying is that you want to only update Bootcamp to the latest version (1.1.1) you do not need to remove your Windows partition and start over.
If you only want to update, go to this page and follow the instructions marked "Updating to Boot Camp 1.1.1 beta".

How to reinstall Windows 7 in Boot Camp without DVD?

Windows 7 in bootcamp really stinks......
Many problems like:
-WMP 12 crashes (always)
-Screen flickers
-Boot screen errors
and many more....
i have used Parallels Desktop 6 and uninstalled it.
pls help, i'm no Mac pro.
just bought mac mini a few months ago and i never use Mac OS X Lion.
Is it possible to reinstall windows only using ISO disc image?

If it is a Mini with Lion, get Parallels 7. Works like a champ
on all my Macs.
If Bootcamp install of Win7 "stinks", how did you install it
in the first place to know that, as Bootcamp installs run native?
Or do you really mean that you tried Parallels and want to
do a native install using Bootcamp?
Some loose ends here that seem somewhat confusing.
Also, exactly what Mini do you have? I have a 2010 Mini
that runs Win7 Pro 64 bit like a champ, in Bootcamp. Watch Blurays
with PowerDVD11 quite often.

Got new harddrive under warranty how to reinstall windows 8???

i have a g505s
i received a new harddrive today and 4 recovery dvds two are labeled disc 2 and have a different part #. the others are disc 3 and disc4
how do i reinstall windows 8?

I wound up solving, or at least working around my problem. Selecting "Custom Install", instead of Upgrade, took me to a dialog box where Installer could format the Bootcamp drive from scratch. Installation then proceeded as expected. Unfortunately this cost me my partition, but that was better than being stuck in this Upgrade Catch-22. Note that formatting and partitioning this drive within the Boot Camp assistant did not solve my problem.

How to reinstall window 8 on Hp Envy m6 Notebook

we need to reinstall windows 8 on formatted disk how do we do this.
The disk has been removed and formatted. Restore did not work and created a partition that blocked off all our memory access. Now we can not get it to restart to windows 8

Was the laptop delivered from the factory with Windows 8? If so the Key Code is embedded in the BIOS. All you have to do is download this .iso and make a DVD from it which will work to install an official licensed activated copy of Windows 8:
https://docs.google.com/a/ericspellmann.com/uc?id=0B0W9PBigPy94aVJWSndyTFNFMzg&export=download
If you need help burning an .iso to a DVD let us know. You can't just copy the .iso file to disk. It is kind of like a .zip file and has to be unpacked and reassembled into a DVD with special software.

How to reinstall Windows 8.1 on Bootcamp?

I am trying to reinstall Window 8.1 on Bootcamp after Disk Utility reported that the hard drive it was originally located on was failing and needed to be replaced. I did so. Now when Windows 8.1 installer launches, it thinks I'm doing an upgrade and insists that I "reboot Windows Normally" and then launch the Installer, which is impossible because it's freshly formatted, NEW hard drive.
Here are the steps that I followed:
1) Disk Utility reports that Boot Camp drive is failing and replace it.
2) Remove failing hard disk, replace with new one.
3) Launch Bootcamp Assistant.
4) Download support drives to USB stick.
5) Begin install process using same Windows disk (64-bit FULL VERSION) used previously.
6) Windows Installer asks for Product Key.
7) I enter product key.
8) WIndows asks to agree to license terms.
9) Setup presents ONLY two choices:
Upgrade Installation
Custom Installation
10) I choose Upgrade.
11) Windows Setup reports that Upgrade can only take place from Windows environment, to eject Windows Install disk, and to reboot into Windows "normally." Cannot eject Windows install disk. Click Close box.
12) Windows Installer relaunches.
13) Install process starts over again.
Please note:
1) This is a fully licensed copy of Windows 8.1
2) I am using it on the same Mac as the original installation. Only change is the hard drive.
3) This is not an authentication issue. Windows accepts the Product Key.
4) Parallels is not involved in any way.
I have talked to several Windows support teams. None were helpful and ultimately said this was a Bootcamp/Apple problem
Apple Support was much more helpful but said they'd never encountered this problem before and were flummoxed.
I have reformatted the Bootcamp hard disk several times. At one point I thought the issue might be that the Mac still thinks the original Windows installation exists because I kept the same name for the new hard disk. Renaming and reformatting did not change the behavior.
Does anyone have any suggestions?

The Windows 7 USB Download tool will allow you to use a USB stick to install any version of Windows.
My netbook is too small for an optical disk so the only way to install Windows is with a USB stick or USB optical drive.

Hard drive crashed how do reinstall windows 7

I began getting hard disk failed errors a today and now it appears I need to buy a new drive. The laptop came with Windows 7 but not disks, how do I get the OS reinstalled without having to buy the OS again?
HP Pavilion dv7

You can't download the files to the new hdd. You use another working machine to dl the files and burn the ISO file to DVD or USB flash drive-then boot the laptop from it.
If you can read the 25 character Microsoft Windows 7 product key, you can download Windows 7 ISO files to burn to a DVD or USB flash drive. The version must match version that came installed on your PC as listed on the Microsoft COA sticker attached to bottom of laptop. Such as Windows Home Premium.
Link to the W indows 7 ISO file downloads:
http://www.mydigitallife.info/official-windows-7-sp1-iso-from-digital-river/
You can use the Windows 7 USB/DVD installation tool to convert the ISO file you download. Link and instructions below. You need a DVD+R or DVD -R . Or a 4 GB flash drive to use the USB method.
http://www.microsoftstore.com/store/msusa/html/pbPage.Help_Win7_usbdvd_dwnTool#installation
Use the 25 character key on the COA to activate the installation.
The key will activate either a 32 or 64 bit installation.
Next go to your support and driver page to install the drivers you need.
