My Windows 10 laptop is having a boot problem. I sent it to the service center and they told me it was possibly the software's problem and asked me to do a clean Windows 10 reinstall.

I don't want to reinstall because most people on the internet says it is the hard disk that goes wrong, so I come up with a nice idea. What if I install a new Windows 10 as a dual boot system and use it to see if it really is the software's problem? Does it help? Can it fully replace reinstalling Windows directly?

  • What is the boot problem? What steps you took to fix the boot problem? check the health of the hard disk.

  • @Zeeshan It is the same problem of this thread. It fails randomly. Booting about 20 times will succeed 1 time. Booting while shaking the laptop is effective, I think😅. Jun 26 '19 at 7:55

Unfortunately, this (installing it along side your other copy) will not give you the objective view you seek. In fact, it may not work at all. Problem is

  • The new Windows install will see the other installed copy, and make changes to the (newly) installed copy, based on knowing the other copy exists. If it allows an additional install at all.
  • If it's the drive itself. How could you possibly ascertain that if you're installing to the same drive?

While what you're attempting to do is a good plan. The only good way to determine that it is not the drive, or that it is the previous install. Would be (if possible) to find another drive, and (temporarily) replace your current drive with the new one, and perform a fresh install to that drive.
