Resolve Dual Boot Windows System That Shows 0x0000006b Error

Written by Lucy John on May 02, 2023

“I have dual boot partitions in my computer. Yesterday my PC experienced a sudden power surge during Win 7 boot up. Later it got stuck on loading screen so I rebooted it. Instead of boot window, I got a message that stated, “Launch startup repair or start windows normally”. So I tried to start Windows normally. Again system hung, but this time on black screen. So I forced it for another reboot and landed at error 0x0000006b. I also tried to boot my computer using another partition but no use; I got BSOD with 0x0000006B. I have tried everything I could, but unable to access my system. If anyone has any useful suggestions, please let me know!”
