Windows 10: Windows 10 automatic reinstall

I have already installed Windows 10 on my brand new PC, and it was working fine for a day or two. Now when I opened my PC, it took me to the installation menu and I have to set up again, but I already have some files and programs downloaded. What shall I do?

:)

 

If you upgrade an OEM and have an issue, can you re-install and upgrade from the previous OS version without activating it first?

Windows 10 uses its own product key.

If you need to reinstall Windows 10, there is no need to reinstall Windows 7, just reinstall Windows 10 either using bootable ISO media or from the recovery drive and it will automatically reactivate.

As Andre said, it's possible that a reset might reinstall Windows 7 (probably if you still have the windows.old folder), or it might automatically reinstall Windows 10 directly. If it does reinstall Windows 7, you still
have the key, so you don't need to worry. If Windows 10 is reinstalled after the reset, it'll get activated automatically. Any digital license that your computer used to have (before the reset) will be detected by the servers.

 

Do you, by chance, still have the Windows 10 installation USB flash drive or DVD inserted in the computer? If so, remove that, and cancel the installation to restart the computer. You bios/UEFI is probably set to boot from USB or DVD first and the computer did a restart to install an upgrade. When it did the restart, the bios/UEFI booted into the Windows 10 installation media left inserted.

When you say it is at the installation menu - which menu do you mean? The first one where you are asked for keyboard and language?

 

Yes, it is the language menu. Though when I talk out the disc and start my PC, there is a message which says reebot and select proper boot device or insert boot media in selected boot device and press a key.

 

Well, to see if the hard drive is showing up and if there is any data on the hard drive, read a quote of my post in the middle of the OP to this thread:

Except I notice you said take out the disc, so you probably have a Windows 10 DVD? Unfortunately the above only works with a USB flash drive. But you can make a DVD of Kyhi's recovery drive if you must boot from a DVD and there are plenty of utilities on his recovery drive to see what the state of the hard drive is and to copy data off your hard drive if you can't fix Windows booting.

 

So you are saying I can't fix my PC because of Windows?

 

We need to figure out what is wrong first. And the easiest way to do that is with a few more tools than just a standard Windows installation DVD.

 

What we need to see is a disk management screenshot:

Make sure to widen all the columns so we can see all the info in the columns. You can get the disk management screen by booting from a USB flash drive or DVD with Kyhi's recovery drive on it:

I think I may have done it. I came back, started up my PC, and went through the installation and the next button was not greyed out. The place I saved it on is Drive 0 Partition 2, partition 1 only had 500 MB, and it said it has to have around at least 8550MB.
It is installing right now and I will mark as solved once it is done.
Also, does this mean I must take out the Windows 10 DVD once I'm done?

 

Yes. After installing you remove whatever source you were installing from, whether it is DVD or USB flash drive.
