The HDD is sometimes detected and sometimes not.

-
Hello,

I have a Lenovo Thinkcentre desktop (E6550 series and configuration quite low- 2 GB RAM, 160 GB HDD, and Windows 7 OS, 32 bit).

The problem is that after I shutdown my desktop it starts automatically after 2-3 seconds and displays 'PXE-E61' error, No HDD detected, No OS found, etc.

I have checked the BIOS settings and have found that HDD is on first position during startup. I have made sure that the 'Automatically restart' option in sysdm.cpl is unchecked. I have checked with a different SATA cable and on a different SATA port, but the problem still arises. I ran 'chkdsk' command and found no issues.

I cannot check the HDD on a different system as I do not have any other means easily available. The different SATA cable that I have used is that of DVD-ROM's. My computer works perfectly well for hours when the HDD is detected and even if I restart the system. The moment I shutdown the system, I face this annoying problem.

Please tell me whether there is an issue with the motherboard, HDD, or others.

If more information is required, then let me know.

System Configuration: Android / Chrome 75.0.3770.143

Thank you
You need to disable the PXE boot. PXE (pixie) boot is a network boot, in the case of deploying an OS image to new PC in a WIDE AREA NETWORK, in an effort to centralize the version in the wild! Your BIOS is reaching out for an answer to its call, and there is no deployment server answering, so it FAILS with an error. So, no local drive is actually failing, it is not detecting a NETWORK DRIVE!

Go into BIOS and disable PXE BOOT!

Restart. If you get an error now, the disk is failing.

I restarted (exiting from BIOS) by pressing F10 and entering 'Y'.

Now this is what happened, the computer restarted and went further and displayed Windows loading symbol. I reached the login screen. I logged-in and finally clicked on 'Shutdown'.

After shutdown, the computer automatically restarted after 6-8 seconds (first the lights glow after 2-3 seconds of shutdown) and proceeded to Windows login page (I didn't get the PXE boot error).

#Moment of realisation.

1) When you replied (and kept repeating) asking me to disable PXE boot, did you mean that I should remove the PCI BEV option from the startup sequence?

2) I am now getting familiar with the webpage. I can see that you update your latest reply to add further comments (sneaky move!)

Yea! Now, if it fails to load, you know the drive has actually failed, or is getting ready to.

Alright. I will keep this in mind.

What about the automatic restart though?

I don't mind raising another question for the automatic-restart-after-shutdown problem, but without any confirmation I don't want to do so.

A failing hard drive will force a bluescreen which can restart.
