You're most welcome.
Hi, I know this is a large thread but I need some clarifications. I have a lenovo y50 that came with a 64bit english windows 8 edition installed and I've upgraded to windows 8.1. Disk Management shows a 260 MB "EFI system partition". So I followed Windows 8 and Windows 8.1 ISO - Download or Create and made with the media creation tool a windows 8.1 english ISO file. I then made a bootable UEFI usb flash drive with rufus (UEFI Bootable USB Flash Drive - Create in Windows) . So now if I understood correctly I have to plug the usb flash drive, run setup, install the updates and then since I have windows 8.1 and a windows 8 key I need to enter the generic key you provided, (FB4WR-32NVD-4RW79-XQFWH-CYQG3). Afterward, check the option to keep my personal files, install w8, choose express settings, sign in, clean up some files and then replace the generic key to my personal key (which I believe I can retrieve with ProduKey - Recover lost product key (CD-Key) of Windows/MS-Office/SQL Server)
Is that correct?
the new windows 8.1 setup media will read the embedded window 8 product and activate windows 8.1
no need to enter any key
Hi, I am running into issues at the very beginning of this repair install process. I ran sfc /scannow in elevated command prompt and it cannot fix some errors, and the DISM check will not work either so I know there are some serious errors with the OS. My laptop came with Windows 8 pre-installed. I updated it to 8.1 from the Windows Store. I do not have the Media Center thing installed. I downloaded a Windows 8.1 ISO from Microsoft and saved it in a New Folder on my desktop. I mounted the ISO and double clicked setup. It gets to "Checking your PC and hangs at 85%. I have tried multiple times and it hangs there for hours. The Windows 8.1 Setup is using 0% CPU in Task Manager as well as Windows Installer. The disk is also showing 0% so it appears to me nothing is happening. Any ideas what could be causing this? No antivirus is running, Windows Firewall is disabled, all non-essential/ non-Microsoft services are disabled. There is no malware detected on the system. I don't know what to try next.
I re-downloaded the 8.1 ISO and ran it. This time it acted differently. It said Windows updates were already installed, but it would have to restart the setup. It restarted and this time I only saw the "Checking your PC" function for a split second then it moved onto "Making sure you are ready to install" (It skipped steps 10-14). It hung up here this time and all processes dropped to 0%. I analyzed the wait chain for the setup process and it was waiting for another process that I didn't write down, but it had something to do with compatibility I think. So I ended that process but then the setup couldn't continue. So I started it again (without restarting my computer) and this time it made it past that screen. So the compatibility portion must have worked because it detected a problem with my Brother printer software suite and asked me to uninstall it. I did that, it wanted me to restart to complete the uninstall but I didn't do that so the setup could continue. It continued and auto selected keep my user files and such so I selected install (FYI this is step 15) and now it is in the process of doing the repair install. I guess the moral of the story is, similar to an earlier post on pages 18 through 20 by highstream, keep trying. I will post with the results of the install.

It took almost 2 hours (slow computer anyways) but it finally installed. So far it seems to have been successful. I don't have time to check every program but Microsoft Office apps are working, internet is fine. Everything appears to still be installed. My copy and paste functions are working again! Thanks a lot for this guide, it should be #1 on a google search for people looking to repair install their Windows 8 OS.
I wish to reinstall windows after having this issue: Keyboards not typing anything - problem with computer? - Computers - Systems
I'm just wondering if this would fix my problem as i think its to do with the OS and also if it's possible i could lose all files by any unlucky chance or screw up and break my computer?
Also is this the same as refreshing or reinstall windows just without losing everything?
