Reinstall windows 10 without losing data

Hi Chris,

It is important to know what was the result of running chkdsk, as this will help us determine if this is a possible hard drive failure. Can you tell us what was the result of chkdsk?

However, if the result did not find any errors, then you can check for corruption in the system files that is preventing your computer from booting up. We suggest that you run the System File Checker tool to address this. Use the installation media to run
the tool.

• Connect the installation media to your computer and then turn it on.
• On the initial setup screen, enter your language and other preferences, and then select Next. If you're not seeing the setup screen, your PC might not be set up to boot from a drive. Check your PC manufacturer's website for info on how
  to change your PC's boot order, and then try again.
• Select Repair your computer. On the Choose an option screen, select Troubleshoot > Command prompt.
  
• Type sfc /scannow and press Enter.
  
  
• Once done, restart the computer.

If still your computer is unable to boot up, then we recommend you refresh your PC. You're not going to lose any files as long as you choose this option. However, we cannot guarantee that you're not going to lose any programs. To do this , follow these steps:

• Connect the installation media to your computer and then turn it on.
• Select Repair your computer. On the Choose an option screen, select Troubleshoot >Refresh your PC.

Let us know how it goes after performing the suggested steps.

 

Reinstall Win 10 without losing data

An in-place repair/upgrade will not delete anything, it just rewrites the system files, leaving all user data and apps alone and preserved.

All other methods, Reset, Refresh, and obviously clean install you would lose apps and data or at least apps on a Refresh.

 

Most painless way to reinstall windows 10?

It depends on the junk accumulated honestly, but there are various methods. You can always remove programs, delete download folder, media locations, etc. As some have suggested, keeping some items on a separate internal storage drive is an option as well. Depends on what you have, what your budget is and how you want to handle your system and data.

The method @RejZoR suggests is sound and a method I've used dozens if not hundreds of time with great success in the field. In many cases though the goal is to keep user data intact, and to repair the OS. In place upgrade as it is called is also only doable in that method if you can boot to desktop, if you can't, it is time for some more advanced options or a format & reinstall.

With Windows 8 and 10 there are refresh and reset options that can be leveraged as well. Hold Shift and click Restart to reboot your system, this will get you into the advanced boot menu, which you'll need to choose advanced options (I forget ATM what it is called) and choose one of a couple items, refresh or reset.

Refresh is essentially In Place Upgrade but a little more aggressive as it wipes the Windows Apps and you may need to reinstall programs. Reset is like an OS reinstall, wipes user data, wipes profiles, registry, performs a install from the system image. Often times I'll do this and bypass using a USB key on a system. Though there are instances where these options will not work if a system has a level of corruption that has not been repaired/resolved. Check the OS Repair link in my sig for more info if ya need.
