What to Do When Windows Won’t Boot. You turn on your computer one day and Windows refuses to boot—what do you do? Where Windows XP might have stopped in its tracks when faced with this problem, modern versions of Windows will try to automatically run Startup Repair. First Things First: Has Anything Changed? Be sure to think about changes you’ve made recently—did you recently install a new hardware driver, connect a new hardware component to your computer, or open your computer’s case and do something? It’s possible the hardware driver is buggy, the new hardware is incompatible, or that you accidentally unplugged something while working inside your computer. If the Computer Won’t Power On At All. If your computer won’t power on at all, ensure it’s plugged into a power outlet and that the power connector isn’t loose. If it’s a desktop PC, ensure the power switch on the back of its case—on the power supply—is set to the On position.

In this case, you’ll have to get your computer’s hardware fixed or get a new computer. Be sure to check your computer monitor—if your computer seems to power on but your screen stays black, ensure your monitor is powered on and that the cable connecting it to your computer’s case is plugged in securely at both ends. The Computer Powers On And Says No Bootable Device. If your computer is powering on but you get a black screen that says something like “no bootable device” or another sort of “disk error” message, your computer can’t seem to boot from the hard drive that Windows was installed on. Enter your computer’s BIOS or UEFI firmware setup screen and check its boot order setting, ensuring that it’s set to boot from the correct hard drive. If the hard drive doesn’t appear in the list at all, it’s possible your hard drive has failed and can no longer be booted from. If everything looks fine in the BIOS, you may want to insert Windows installation or recovery media and run the Startup Repair operation. This will attempt to make Windows bootable again. For example, if something overwrote your Windows drive’s boot sector, this will repair the boot sector. If the recovery environment won’t load or doesn’t see your hard drive, you likely have a hardware problem. Be sure to check your BIOS or UEFI’s boot order first if the recovery environment won’t load. You can also attempt to manually fix Windows bootloader problems using the fixmbr and fixboot commands. Modern versions of Windows should be able to fix this problem for you with the Startup Repair wizard, so you shouldn’t actually have to run these commands yourself. If Windows Freezes or Crashes During Boot. If Windows seems to start booting but fails partway through, you may be facing either a software or hardware problem. If it’s a software problem, you may be able to fix it by performing a Startup Repair operation. If you can’t do this from the boot menu, insert a Windows installation disc or recovery disk and use the startup repair tool from there. If this doesn’t help at all, you may want to reinstall Windows or perform a Refresh or Reset on Windows 8 or 1. If the computer encounters errors while attempting to perform startup repair or reinstall Windows, or the reinstall process works properly and you encounter the same errors afterwards, you likely have a hardware problem. If Windows Starts and Blue Screens or Freezes. If Windows crashes or blue screens on you every time it boots, you may be facing a hardware or software problem. For example, malware or a buggy driver may be loading at boot and causing the crash, or your computer’s hardware may be malfunctioning. To test this, boot your Windows computer in safe mode.

If you have important files that will be lost and want to back them up before reinstalling Windows, you can use a Windows installer disc or Linux live media to recover the files. These run entirely from a CD, DVD, or USB drive and allow you to copy your files to another external media, such as another USB stick or an external hard drive. If you’re incapable of booting a Windows installer disc or Linux live CD, you may need to go into your BIOS or UEFI and change the boot order setting. If even this doesn’t work—or if you can boot from the devices and your computer freezes or you can’t access your hard drive—you likely have a hardware problem.
