Missing %hs file operating system refuses to start.

[Jonjo]

Hi, im running windows 7 on a laptop. It started to freeze while booting. I followed steps to fix this including last known good config and, system resore. I then got the win7 disk in the hope of using the upgrade facility to try and repair this but it asks me to restart the comp, then reload the disk in normal mode, as the os is failing to load, it is in a constant loop. I haven't tried a clean install but im hoping not to do this as there are some sensitive/important files on here(its used for social work) and im hoping not to lose them, could anyone help with this please, thank you.

Welcome to7F .
I would first check to see if the HDD (you have a Hard-Drive right?) is in a good condition.

   Warning

The Following Method Should NOT Be Performed On An SSD!

Testing the HDD:

1. Perform a Disk Check | Disk Check- Scroll down to OPTION TWO of the tutorial and use the /R switch in the CHKDSK command | chkdsk C: /R.
2. Then Post the Disk Check results following | This Tutorial.
3. Once back in Windows, download Crystal Disk Info and post a screenshot (multiple shots if you have more than one drive).
4. Download SeaTools for DOS if you don't want to use a CD to test the HDD you can use YUMI – Multiboot USB Creator to create a bootable USB (instructions are found at the bottom of both pages).
5. If SeaTools for DOS is unable to recognize your HDD:
6. Visit HDDdiag and follow the instructions | Or follow the instructions below.

If SeaTools For DOS does not recognize the drive;
Boot into the BIOS using the *Fx key.
Look for an entry called SATA Mode (or something similar), it should be set to IDE / AHCI.
It's probably set to AHCI which is why SeaTools doesn't recognize them in the DOS environment.
Set it to IDE then save and exit usually by pressing the F10 key.
Now boot into SeaTools and it should detect the drives.
Start the Long Test and let it run.
Upon completion don't try to boot into Windows as it will only result in a BSOD, go back into the BIOS
and change the SATA setting back to what it was in the first place.

• *Popular BIOS access keys.

Let us know the results.
