Laptop freezes at dell logo

2 days back i deleted 2 partitions in my internal hard disk by using disk management in windows 10.
The partitions had ubunut’s / and /home folders. Suddenly windows
started hanging and slowing down.I shutdown and started again.I wont go
past the dell logo scree. Pressing F2/F12 does nothing. Booting from
other device is also not an option as f12 wont work.So i read up some
posts and decided to remove the hard disk .I can now boot from a usb.But
with the Hdd attached i cant do anything. Does this have anything to do
with POST? Any solution is appreciated

Hi there,

Try to run a diagnostic on the drive to see if this way you can see if the drive has any problems. You can check the drive with DLG , here is a link to download this software:

DOS version

Windows Version:

Use the DOS version since it should boot from there and be able to diagnose the drive. Please check this instructions:
