Windows 10: How do I save my files if Windows 10 is corrupted/won't boot?

Here's the situation...

1) Computer was running very slowly. I re-booted, thinking that might help.

2) Since that time, it won't boot Windows. I just see the Dell symbol on startup (it's a 1.5 year old XPS 8900 with no serious prior problems) and then it goes to a new screen and says it doesn't have a bootable drive.

3) So...I ran diagnostics (both on my own, and then a Dell tech told me to do the same things). It's supposedly not a hardware problem. Instead, Windows 10 is the issue. So I had them overnight me an installation disk (it came pre-installed, so I didn't have the CD before).

4) It's VERY important to me to save my files if possible. Some are for work, some are family photos...some are backed up, but some from the last couple months are not (I just haven't been diligent enough about that). The computer has two internal drives...1 TB main drive with Windows AND some valuable files on it...and another 2 TB drive which is a backup and where I store most of my photos (my side job is photography so I generate a ton of files every year). I would really love to recover both if possible.

5) Called Dell again tonight after I got the installation disk in the mail, and the tech unfortunately didn't really know what he was doing...after just one failed attempt to reset the computer WITHOUT losing files, he immediately wanted to give up and click the "scorched earth" (delete everything) option. I talked him out of that, and he said the other option was to create a bootable USB. I used my laptop (which I'm currently on) and went to the Dell support site and downloaded the recovery image (.iso file) and tool (.msi file). That's where things stand. I haven't put those on my USB yet, but I have an empty 16GB stick ready to use.

My main questions are...

1) Will I actually be able to back things up if I use this method? I have an empty 2 TB external drive I could transfer things to if I simply gain access to the files on the internal drives. Again, I also have this laptop available to aid in the process. I don't have another desktop that I could put the drives in, so that isn't an easy option...however, I'd be willing to do that as a last resort. Anything to save the data.

2) If this IS a good method (USB recovery), what are the steps I need? If I could just back everything up, then at that point I don't really care if I have to re-format...I'll have my files anyway.

Thanks so much for reading and I hope I can make this work with your help!

I think my copy of Windows 10 is corrupt

I think my saved copy of Windows 10 is corrupt. I tried to do a reinstall saving all my files, settings and apps but it did not resolve the issue I have so think it is actually my copy of Windows 10 that is at fault.

How can I obtain a clean copy and then reinstall saving my apps. settings and files?

 

Klondike Solitaire Displays Error Message During Play

I recently upgraded to Windows 10 and found out that Klondike Solitaire, a web-based app which comes with it, won't play correctly. I keep getting an error message that the Save File is corrupt and a new Save File Will Be Created. I'd like to get rid of
that problem but don't know how. Anyone know?

 

Make a bootable USB flash drive of Kyhi's Recovery Tools:
Windows 10 Recovery Tools - Bootable Rescue Disk - Windows 10 Forums

Then you can boot into that and either use file explorer to copy files from the old Windows partition to the second hard drive, or make a complete backup image of the Windows partition to the second hard drive using Macrium Reflect. You can explore the backup image from Macrium Reflect Free (which can be installed once you restore Windows 10) to retrieve specific files from it.

 

Appreciate the link, but I'll be honest...I'm a little unsure of the step-by-step process. And I don't want to screw it up when so much is at stake. If you or someone else wouldn't mind explaining a bit more thoroughly exactly how I can get to the point of accessing my old files...I'd be quite thankful!

A few specific questions to start...

1) Which version do I download? x64 or x86?

2) Can I then just copy that .iso file directly onto a brand-new flash drive? Or do I need to format it a particular way?

3) Once I have the .iso file on there, what are the exact steps I follow when I insert that flash drive in the "broken" computer and boot it up?

 

I recommend a flash drive between 8 and 32 GB. You will insert the flash drive with Windows running. Right click on the start icon and select either Command Prompt (Admin) or Powershell (Admin) and run the following commands to prepare the flash drive:

diskpart
list disk
select disk # <- replace # with the actual disk number of the flash drive.
clean <- This ERASES the ENTIRE drive selected, so make sure to select the flash drive in the step above.
create part pri
format fs=fat32 quick
active
assign
exit
exit

The USB flash drive will now have a drive letter assigned to it. Download the 64-bit version of Kyhi's Recovery Tools. Right click on the saved ISO file and select Mount. A driver letter will appear from the mounted ISO file. Copy all the files and folders from the mounted ISO file to the USB flash drive.

Insert the flash drive in the problem computer. When you turn the computer on, there will be a key to repeatedly press to enter into the boot menu or UEFI/BIOS setup. It varies from computer to computer. It might be DELete, ESCape, INSert, F2, F11. The key to press might be displayed in a text or splash screen when the computer is turned on. You can probably google it "BIOS setup key <make/model> computer or motherboard"

Once you select the USB flash drive to boot from, it should boot into Kyhi's Recovery Tools which is a mini Windows 10 with lots of backup, restore and troubleshooting programs installed.

 

"When you turn the computer on, there will be a key to repeatedly press to enter into the boot menu or UEFI/BIOS setup."

CapnBlubs: As soon as you see the Dell splash screen appear, keep hitting F2 to get to boot menu and prioritize the usb there to use the tools for your file backup. A good case for regular file backups in future, just saying. Good Luck

 

Thanks for the help! I'm done with the first few steps, but I don't have an option to "mount" when I right-click the .iso file I downloaded. Do I need a program to do that?

 

"but I don't have an option to "mount" when I right-click the .iso file I downloaded. Do I need a program to do that? "

No, Windows should mount it as a separate letter drive which you can open. Double-click the ISO and see if a new drive is listed under 'This PC' in file explorer L-column.

 

Sometimes, right-click doesn't work to mount an ISO as a volume (with drive letter). When that happens use the PowerShell "Mount-DiskImage" command instead. Here's a link to a tutorial that explains how to use it (see Option #2): Mount or Unmount ISO and IMG file in Windows 10 Windows 10 Virtualization Tutorials .
HTH,
--Ed--

 

I think I successfully created the flash drive, and then I booted, hit F2 and put the flash drive first in the boot sequence.

But after the Dell logo and a few seconds of waiting, I get a blue screen with an error message (pecmd.exe - Application Error)

"The instruction at 0x00007FF924B5A53 referenced memory at 0x(long string of zeroes)C2A0. The memory could not be read. Click on OK to terminate the program."

And my mouse cursor isn't actually appearing so I'll probably just have to either use the keyboard or hold the power button in.

Any ideas?

 

Not sure why it would've made any difference but I tried again, hitting F12 (one-time boot menu) this time.

And it loaded! I'm in the process of copying files to an external drive now. If I can get it all backed up I'll be far less worried about the next steps to fix Windows. I don't want to jump the gun on assuming I'm out of the woods, but I do want to sincerely thank you all for your assistance, especially NavyLCDR!

But as far as that goes...do you all have any recommendations? Is it worth trying to fix, rather than just start over?

 

I think most of us here would agree with a clean install of Windows 10. You can easily make a Windows 10 installation USB flash drive using the Media Creation Tool:
Download Windows 10

When you get to the first screen asking for language and keyboard options, press Shift + F10. That will open a command prompt. Then you will want to erase your hard drive by running:

diskpart
select disk 0
clean
exit
exit

When you get to the option to do a custom install, that is what you want to pick. Then on the next screen highlight the unallocated space on the drive and click Next to let Windows install setup the disk the way it wants to. A few hints to getting a good, clean, successful install of Windows 10:

Have nothing connected to the computer other than the minimum to install Windows; mouse, keyboard, monitor and the installation USB flash drive. If you have blue and black USB ports, everything should be plugged into black USB 2.0 ports.

Do not connect to the internet when Windows 10 wants to connect. That also means if you are using a wired network connection, pull the plug, along with everything else you don't need according to the first hint. Do not connect to WiFi when asked.

When you get to the screen asking for an email to use for a user account - keep clicking the button to skip the screens, or do this later, or I don't have an email address. Whatever button will skip it. You will eventually get a screen that asks for a User Name and Password that you cannot skip. Enter your desired user name there, but do not use an email address! I use John, because that is my first name.

Once Windows 10 finishes installing and you get to a desktop and everything has settled down, then you can connect to the internet and Windows 10 will activate and pull updates. Then you can add any other hardware you need, like the external disk drive. Also, if you want to use a Microsoft account login, you can change the local user account to use a Microsoft Account login.

We also recommend making a second local user account, changing that to an administrator, don't forget the password, and not using that account regularly but just leave it on there available for emergency use should something happen to lock you out of or corrupt your user account that you regularly use.
