Windows 10 won't boot? Don't despair if your computer won't start. There's a huge number of fixes out there. The trick is knowing which tools to use first. Our advice is to start with the easiest fixes and, in order, move to the harder ones.
It is an alternative boot scheme that starts your computer with a minimum of software. The modified boot process can bypass driver and software problems. The weird thing is, sometimes starting the computer in Safe Mode can fix boot problems. It's not always clear what processes run in Safe Mode, but experience has taught me it's an effective and easy fix.
After creating the recovery drive, you can boot your computer from it only if you've turned on USB drives as bootable from the POST environment, also known as UEFI or BIOS. After enabling USB drives as bootable, insert the drive into your computer and restart (this may require hitting the reset button or holding the power button down for a few seconds).
Removing the battery will help you discover if a hardware problem is to blame. The key here is to ensure that you're only testing one element at any given time. If power issues interfere with the startup, it's crucial that you know whether the battery, charging cable, or another component requires replacement.
A serious issue with Windows 10 updates is that sometimes your computer won't boot because of a conflict with a USB device. You can solve this problem by unplugging all USB devices (and any other unneeded peripherals) and restarting the computer.
The reason Secure Boot causes problems is that it's designed to protect computers against malware. Because it checks the drivers and hardware loaded by Windows at startup, any driver or hardware component not recognized by the system will generate an error at boot.
It might still be possible to boot into the Command Prompt. Using this interface, you can perform more troubleshooting procedures. You'll need to have Windows 10 on a bootable disk or USB drive to perform the procedure, so use another computer to set that up before you get started.
To boot to the Command prompt, start your computer. While it's initializing, watch out for details of a combination of keys that will allow you to enter the BIOS. This information is typically delivered alongside the vendor logo.
Navigate to the Boot tab and make either the USB or DVD drive the first bootable device. Your choice here will depend on where your copy of Windows 10 is located. Again, the specifics of this process may vary from one system to another, so consult the on-screen instructions.
Startup Repair is a general-purpose troubleshooter for issues that prevent Windows from starting up. If you're struggling to find the source of your boot issues, it's a good idea to run the utility in case it can find a solution.
Once this is done, input list volume to print the details of all the volumes currently hooked up to your system. If your boot volume doesn't have a letter drive assigned, you will need to assign one.
Restart your computer, and you should find that the legacy bootloader interface has replaced the Windows 10 iteration. You should have no further problems entering Windows 10 Safe Mode or accessing your existing OS installation.
A "clean boot" starts Windows with a minimal set of drivers and startup programs, so that you can determine whether a background program is interfering with your game or program. This is similar to starting Windows in Safe Mode, but provides you more control over which services and programs run at startup to help you isolate the cause of a problem.
On the Startup tab in Task Manager, for each Enabled startup item, select the item and then select Disable. (Keep track of which items have been Disabled. You will need to know this later.)
On the Startup tab of System Configuration, select OK. When you restart the computer, it will be in a clean boot environment. Follow troubleshooting steps to install, uninstall, or run your application. Your computer might temporarily lose some functionality while in a clean boot environment. Reset the computer to start normally after clean boot troubleshooting and resume functionality.
If your problem does not occur while the computer is in a clean boot environment, then you can determine which startup application or service is causing the problem by systematically turning them on or off and restarting the computer. While turning on a single service or startup item and rebooting each time will eventually find the problematic service or application, the most efficient way to do this is to test half of them at a time, thus eliminating half of the items as the potential cause with each reboot of the computer. You can then repeat this process until you've isolated the problem. Here's how:
On the Startup tab of System Configuration, select OK. When you restart the computer, it's in a clean boot environment. Follow troubleshooting steps to install, uninstall, or run your application. Your computer might temporarily lose some functionality while in a clean boot environment. Reset the computer to start normally after clean boot troubleshooting and resume functionality.
The computer restarts in a clean boot environment. Follow troubleshooting steps to install, uninstall, or run your application. Your computer might temporarily lose some functionality while in a clean boot environment, however that functionality will return. Finish troubleshooting and reset the computer to start normally.
The Windows 10 boot process is quite simple. When your computer starts, the BIOS or UEFI Firmware is loaded, which performs a small set of checks on your hardware called the Power On Self Test (POST). The BIOS then scans the hard disk master boot record, which loads an essential file into main memory called WINLOAD.EXE. This kicks off the start-up process by loading the NTOSKRNL.EXE (NT Kernel, the heart of Windows) and HAL (Hardware Abstraction Layer.) Windows 10 then performs tasks such as initializing your hardware like your mouse and keyboard and reading the Windows Registry and user profile.
The first thing you can try is booting into the recovery environment, if possible, and then performing a startup repair. To access the recovery environment, turn your computer on and off three times. While booting, make sure you turn off the computer when you see the Windows logo. After the third time, Windows 10 will boot into diagnostics mode. Click Advanced options when the recovery screen appears.
This command will attempt to write a new boot sector on the hard disk if Windows detects damage. Usually, this happens in cases where an older version of Windows was installed, or a non-compatible operating system such as Linux was installed.
Your next best option is to try salvaging your data and then reinstalling Windows 10 and your applications. If you have your Windows 10 install media, you can boot from it, then perform a custom install. This will create an archive of the old installation called Windows.old. You can then recover your personal files from this folder. Make sure you perform a custom install that migrates your Windows.old data. Otherwise, all your data will be erased.
After these 2 methods failed to fix it for me I unplugged 2 of my harddrives.The reason being that my system boots of a NVME ssd which required some tinkering with windows 10 + bios to get it booting smoothly because it kept wanting to prioritize booting off my regular harddrives.fortunately for me I just had to slide the 2 drives out an inch or so inside their mounting cradles and then rerun the automatic startup repair utility and I was back in windows the next minute. (after hours of scratching my head looking at the spinning icon before i got this done)
2. Booting from the thumb drive allows me to boot into safe mode and transfer some current files created since my last back-up, to the back-up drive. Is there also a repair program that will do this in Safe mode?
Finally, enable Safe Mode in either normal mode or with networking (this enables drivers that connect you to the internet) and restart your PC. On the next boot, press F4 to boot your PC in Safe Mode.
One such tool is Startup Repair, which helps users in removing startup issues like the one you are facing. It does this by fixing the corrupt master boot record (MBR), partition table, or boot sector, which are all essential components for a successful boot of your PC into Windows 10. 2b1af7f3a8
