I'm currently using my laptop for 2 months and today when I shut down my Dell Inspiron 15 a while ago and open it again after an hour I continuously get this error

• :(
• Your PC ran into Problem and it needs to restart. We're just collecting some error info, and then we'll restart for you.
• If you'd like to know more you can search online later for this error. 0xc000021a

After it automatically restart it says

• RECOVERY
• Your PC couldn't start properly
• After multiple tries, the operating system on your pc failed to start, so it needs to be repaired
• Error code: 0xc0000001
• You'll need to use the recovery tools on your installation media. If you don't have an installation media (like a disc or USB devices), contact your system administrator or PC manufacturer.

Whats should I do I encounter this problem about 3 hours ago help me please!!!

Thank you!!
