Disk problems, chkdsk unexpected restart

Hello, I've been having some hard drive problems with my Lenovo laptop.

After a recent restart my computer automatically booted into startup repair. There it ran for around 12 hours saying "repairing disk errors" before I forced closed it.

I then tried booting into safe mode, but after selecting safe mode it just redirected automatically to startup repair.

I closed the computer again and managed to get to the recovery environment command prompt, where I ran chkdsk /r.

It ran very slowly, found some bad sectors and indexes, but it was seemingly making progress and recovering bad files.

Then it got midway through stage 4 and the computer suddenly restarted, not finishing chkdsk and booting into startup repair again.

Now I'm trying to run chkdsk again, but I'm back at the start.

I'll try one more time, but if it crashes midway through again, what should I do?

I found very conflicting opinions online on whether bad sectors always indicate a failing disk, a lot of people say some bad sectors are OK or even usual. There are also people saying chkdsk, especially chkdsk /r can run for a very long time.

HDD 160 GB, 4 GB RAM, Intel dual-core processor around 2.5 GHz.

Can you tell what the DISM and SFC commands for Win 7 are? DISM restore health doesn't seem to work.

Hi,
DISM wasnt really set up for W7 users, you need to run KB947821.. SURT (system update readiness tool)
it is the predeccesor for W7

sfc /scannow is the command

Hello, I ran SFC /scannow and got the error that it can't run because there's a system repair pending (like I mentioned, the computer automatically boots into system repair).

I then ran DISM /image:E:\ /scratchdir:E:\scratch /cleanup-image /revertpendingactions, which is supposed to be a legitimate command even for Windows 7.

I got error 1016: "An error occurred while attempting to access the image."

I'll try to get the log file.

NO

DISM was not designed for W7, you have to use the KB i gave you.
because there is a sytem repair in progress we need to stop it, so your in a stable mode

from the reset you need to access command mode during the repair stage set-up and use insert this line, to cancel it
ADMIN Command Prompt
then In the popup window, type the following command and hit Enter to continue.
del X:\windows\winsxs\pending.xml
