Boot loop, unable to boot up after switching harddrive.

[Aphim]

So I recently got some laptop parts to upgrade my laptop with from my friend who had the same model. Everything was working until I switched the harddrive (Big mistake). I thought since the model of laptops was the same, it could just be swapped in, but I was wrong and now I can't completely bootup my laptop with either drives. (I'm currently trying my fixes on my original drive)

On a restart after it downloaded some drivers, the device scanned the harddrive for consistency which deleted a few things. Since then it is mostly unable to boot (there have been a few times that it booted up but they are few and eventually they shut itself back down) and throws me in a bootloop even after I switched the original harddrive back in. I can boot it up successfully into safemode and use my windows recovery disc to boot up my laptop but neither of those are permanent fixes.

I've tried using the built in startup repair multiple times but it says it is unable to fix the problem. Looking at the logs of the scan, it says the root of the problem is a corrupt system volume disk.

I've also tried using system restore to earlier time but no luck. I've tried last known good configuration but didn't work.

I've tried performing a chkdsk function which was not able to fix the problem.

I've tried using bootrec. one of the functions showed that I had 0 windows installed. looking up and following the /rebuildbcd function from the microsoft site I fixed that problem so that it shows 1 windows install, but the boot problem persists.

I've tried using the sfc/scannow function but there were some files that were not able to repaired and the boot issue is still here.

Now I'm pretty much out of ideas. I would preform a re installation of windows 7 but I don't own a disc and my product key doesn't allow me to get the iso since its a preinstalled version on my laptop.

"notepad.exe.mui" seems to be the corrupted file, not sure if it is related.

Try:
Attach the original drive in your laptop and run PAR - http://www.sevenforums.com/tutorials/292068-make-windows-7-bootable-after-motherboard-swap.html

Thanks for the reply.

Using the software from the link, both the transfer motherboard function and bootup repair function failed to change anything. On the original harddrive it still fails to boot up without any sign of change.

Using the software on the new harddrive however made it go to a "setup is preparing your computer for first use" screen. It then still fails to fully bootup. Running the startup scan found a corrupt system volume and says it fixed it but the bootup fails. Doing the startup scan again finds nothing, but boot up fails with a new error popup saying winlogon.exe - corrupt file and a whole chain of numbers and letters which I can provide it necessary. Using the startup scan a third time finds the same issue as the first time and fails too boot.

At this point, I don't even care which drive I get to work, I just want to be able to use my laptop.

See http://www.sevenforums.com/tutorials/219533-troubleshooting-windows-7-failure-boot.html for anything you have not tried yet.

Perhaps consider a repair install if you can get to Safe Mode now - http://www.sevenforums.com/tutorials/3413-repair-install.html

Until then you can boot with a Linux Mint MATE DVD/USB (no installation needed) to at least browse Internet, perhaps use some office applications. You can also use Linux to copy paste your files if you decide a clean re-install (best option but requires the most effort) - http://www.sevenforums.com/tutorials/219487-clean-reinstall-factory-oem-windows-7-a.html#post1839164
