Windows won’t boot!
It’s rare — but not unheard of — for updates to screw your system up so much it can no longer boot into Windows successfully. After several failed attempts, Windows should give you the option of booting into Safe mode or bring up the recovery menu. From here try Startup Repair or System Restore to roll your PC back to the Restore point taken before the update was installed. Note: this may not be an option if you’re running Windows 10 and didn’t switch System Restore back on after installing the April 2018 Update.
Other options will involve recovery media — if you regularly back up using a tool like Macrium Reflect Free ( www.macrium. com/reflectfree), roll back to your last backup using its boot media. Or you could boot from your Lazesoft Recovery Suite rescue media ( bit.ly/2LtlgPq) and try its Windows Recovery tool. If it fails, use the Data Recovery component to save your data or take a disk image before booting from your Windows rescue or installation media and try a repair install — this involves installing Windows 7 over the top of itself, or performing an ‘upgrade install’ with Windows 8.1 and 10 boot media.
System Restore — if it’s working and accessible — is your easiest route to undoing a catastrophic failed update.
