Possible HD failure
I installed a new 1 GB SSD in an HP laptop ;ess than three months ago. A couple of times recently Windows 11 has crashed with a BSOD, and when I restarted the laptop would not boot up, giving me a boot device not found error message, and refused to boot. Several attempts resulted in no luck. I finally went into the BIOS, opened the boot manager, changed the UEFI boot device to an external device then changed it back to the hard drive without actually saving in between, exited the BIOS and rebooted and the machine rebooted, albeit very slowly with a long hiccup after the logon screen appeared and I entered the PIN.
This has happened a couple of times.
Is this a drive failure problem or something else?
