Windows 10: Can not boot to Windows 10 or reinstall the OS

My MSI Z16 gaming laptop went wrong on Sunday. When I started it, it stayed in the BIOS interface and couldn't boot to the Windows 10. No matter how I modify the BIOS settings, I can't get to the Windows. I'm not sure about the cause.Then I attempted to reinstall Windows 10. I downloaded the installation media to a flash drive with another computer. I tried every option in troubleshot, only command prompt worked. I found I can still access the only hard drive a 2TB SSD in my laptop. I made a backup of my files with cmd and I noticed that I couldn't copy a few large files Several videos, .zi

windows 10 slow boot

I was having a slow boot issue on my Windows 7 install a little while back. It would take about 30 - 40 extra seconds to boot up for whatever reason.

I would try following these steps, while this didn't solve my issue, it did increase Read/Write to where it should be.

In the end, I had to reinstall my Windows 7 entirely to fix the booting issue. It was taking around 35 seconds to boot, and after the fresh install it takes about 7 seconds to boot.

 

Most painless way to reinstall windows 10?

It depends on the junk accumulated honestly, but there are various methods. You can always remove programs, delete download folder, media locations, etc. As some have suggested, keeping some items on a separate internal storage drive is an option as well. Depends on what you have, what your budget is and how you want to handle your system and data.

The method @RejZoR suggests is sound and a method I've used dozens if not hundreds of time with great success in the field. In many cases though the goal is to keep user data intact, and to repair the OS. In place upgrade as it is called is also only doable in that method if you can boot to desktop, if you can't, it is time for some more advanced options or a format & reinstall.

With Windows 8 and 10 there are refresh and reset options that can be leveraged as well. Hold Shift and click Restart to reboot your system, this will get you into the advanced boot menu, which you'll need to choose advanced options (I forget ATM what it is called) and choose one of a couple items, refresh or reset.

Refresh is essentially In Place Upgrade but a little more aggressive as it wipes the Windows Apps and you may need to reinstall programs. Reset is like an OS reinstall, wipes user data, wipes profiles, registry, performs a install from the system image. Often times I'll do this and bypass using a USB key on a system. Though there are instances where these options will not work if a system has a level of corruption that has not been repaired/resolved. Check the OS Repair link in my sig for more info if ya need.

Upgrading cpu and mother without reinstalling windows 10

in most cases you can do exactly what you are trying to do by taking the os drive and plugging it into the new system and booting in safe mode. once in safe mode open a command prompt as administrator and type "set devmgr_show_nonpresent_devices=1" hit enter. then type "start devmgmt.msc" hit enter again and device manager should open up. after that click the "view" tab and select "show hidden devices". then you just expand each list and unistall all the drivers that are slightly transparent. once you are all done go ahead and reboot the system and install all the new drivers. in most cases this is enough and does not need anything more done.

edit: just boot the os into safe mode the first time and let it install drivers then reboot and fallow the steps i listed above. back with windows vista and earlier windows versions this would be problematic but sense 7 ive found that swapping boards from different manufacturers and even amd to intel has become mostly doable. ive done it a handfull of times.
