What do I do when my HP laptop after being formatted shows "Your computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed. To install windows click ok to restart the computer and then restart the installation".
If you are encountering this error message after formatting your HP laptop and trying to install Windows, there are a few steps you can try to resolve the issue:
1. First, try restarting your computer by clicking on OK as instructed in the error message.
2. If the error persists, restart your computer and boot from the Windows installation media (USB or DVD) instead of the hard drive. You may need to change the boot order in the BIOS settings to prioritize the Windows installation media.
3. Once you have booted from the installation media, follow the on-screen instructions to reinstall Windows on your laptop.
4. During the installation process, make sure to format the hard drive and create new partitions if needed.
5. If the error still occurs, try reformatting the hard drive using a different computer or using a third-party partition manager software before attempting to reinstall Windows.
6. If none of the above steps work, consider seeking assistance from HP support or a professional technician to diagnose and resolve the issue.
It is also possible that the installation media itself is corrupted or the hard drive may be failing, so it's worth trying a different installation media or testing the hard drive for issues if the problem persists.
