Windows 10: Laptop does not boot

I have a Dell inspiron laptop with windows 10. It had been working nearly 3 months without any trouble. Last week i installed Avast
anti virus program , After finishing installation it does not restart. Tried several times result is the same. Now when i switched on it asks my
password and after giving it it does not boot but only an arrow appears continuously, When i press ctrl+alt+del keys i get on the screen
lock
switch user
sign out
change password
task manager

When i sign out and try to reboot something happens.

Please help me to solve this problem.
Thanks

laptop doesnt boot automatically

This is what happened.

1. Did a repair install and later disabled hibertnate in CMD.
2. Enabled legacy option ROM in BIOS.
3. After a few times startup ( i used the system in such mode for 5 days), changed boot option back to default.
4. Vola!! It boots automatically to win10 without any keypress. Tested it with many starts to confirm the same.
5. Re-enabled hibernate option using CMD and later selected Fast Startup.
6. System booted normally, without the need for any keypress.

I do not know exactly whether such steps resolved the problem or what else happened, hence cannot suggest above steps.

Many thanks to all members who helped to troubleshoot problems.
