sfc /scannow won't run | stuck on win7 logo screen

Hi everyone,

When I run sfc /scannow I get to see "this process will take some time." and a blinking cursor whereupon absolutely nothing happens; this screen stays on forever.

My Lenovo Y500 won't boot into win7 anymore all of a sudden and after puzzling around for several hours now I'm close to despair. The laptop freezes at the windows logo screen, so pretty much at the beginning of booting. Laptop won't boot into safe mode, BIOS reset didn't work out, only working option is "repair your computer" from where I'm able to run command prompt. However sfc /scannow seems to freeze / go on forever. I have a Lenovo Y500 with 1TB HDD & 256 GB SSD (system) installed. When I run CHKDSK on the SSD it also freezes in stage 2 at 16%; no error warning, the screen just stays on forever. When I boot from a rescue disk however I'm able to access all the files on the SSD without any errors.

I've added a picture of the sfc /scannow process where I'm stuck.

Looking forward to some advice,

Kind regards
Steven

Thanks for your reply.

I didn't make a repair disk on the first install, but I do have the installation disk. When I run Startup Repair it yields no errors; it claims everything is fine (ran it several times). I made sure I marked system reserve as active. Rebooted my pc, still freezes at logo screen.

Next I tried:

Code:

Bootrec /Fixboot
Bootrec /Fixmbr
Bootsect /nt60 all /MBR

These commands executed succesfully; rebooting again freezes at logo screen.

Next I tried:
bcdedit /export C:\BCD_Backup

Code:

c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /RebuildBcd

Again, rebooting stopped at the logo screen.

Windows still won't boot normal, nor in safe mode. Both chkdsk and sfc /scannow processes freeze.

Meanwhile I've booted Parted Magic via CD and ran a health check on both SSD and HDD; both came out healthy.

Next I'm going to delete my system reserve partition and run System Repair again; fingers crossed. If that doesn't work I'm gonna try a repair install.

Kind regards,
Steven

Hi,

Maybe it's hard to read in the picture, but I entered the following:

Code:

sfc /scannow /offbootdir=c:\ /offwindir=e:\windows

Is this correct?

Oh thanks. Tried it with /offbootdir=e:\ /offwindir=e:\windows this time. Still no progress, its running now quite some time.

Furthermore a repair install doesn't work since you have to run the installer from within windows, which i cannot access.

It seems like it didnt even start. D: isnt my system drive, nevertheless I also tried it. I included a picture of my screen. This text stays on forever and my pc doesnt get passed it. Command Prompt doesnt respond anymore from this point on, i cant even enter "exit".

Regards,
Steven
