You run an operation that requires a restart into the bluescreen mode. After an autonomous bluescreen operation, the system fails to boot, saying “Interrupted operation: insert the recovery CD or other recovery media and reboot your PC”
This means the operation hasn’t been completed. The system retains our custom MBR that links to our bluescreen boot manager, and MBR has a record saying a bluescreen operation pends completion.
To continue the operation, boot from a Paragon recovery media (WinPE or Linux, either works). After doing that and opening the full scale UI, you should receive a prompt to continue the interrupted operation. After it’s done, the MBR will be updated to default and the system will reboot normally. It’s very important to complete the interrupted operation (whatever it was) because otherwise data loss may ensue.
