I have HP laptop having multi os ( windows 10 , macOS & linux) and using clover bootloader ( EFI partition & GUID table ). There was sync time problem among the os . So I googled my problem and found the solution in which a dword "RealTimeIsUniversal" is created and set to value 1. After doing this , I restarted the laptop and encountered a serious problem . It is showing now this everytime when I poweron my laptop ::

 

 

 

"""""""

 

Boot Device Not Found

 

Please install an operating system on your hard disk.

 

Hard Disk <3F0>

 

"""""""

 

 

 

Using bios system diagnostics program , it is showing this ::

 

SMART Check : PASSED

 

Short DST : Failed

 

 

 

Has my laptop hard disk got failed now ??

 

Is it solely caused due to that registry editing ??

 

Can I get my all OS back by undoing that ?

The harddisk had been working fine till now and encountered no hard disk issue.

There is important data in all OS.

 

Please help me & guide me .

 Short DST : failed

You need to replace your hard drive.  You should be able to purchase the parts on the notebook's HP Parts Surfer Page  http://partsurfer.hp.com/Search.aspx?SearchText=XD403EA

Had you previously created any Recovery Media such as a thumbdrive?  Without this you'll be unable to reinstall the operating system when you replace your hard drive. 

You'll need to contact HP Support in order to get one of these kits.  The number for US/Canadian customers is 1-800-474-6836.

So changing registry has not affected hard disk ?

 

Has whole hard disk got corrupted/damaged or just the EFI partition ?

Changing a DWORD in the registry (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation\RealTimeIsUniversal) that switches between localtime and UTC, does not affect the hard disk

 

A short dst failure indicates that the hard disk is failing or has failed. You will need to replace the hard disk with one of the same or larger capacity and run a factory restore via the recovery disk set or USB recovery media.

After spending my whole day , I fixed it with just 1 command.  :yes:

 

Here is what I did ::

Boot Kali Linux from pendrive.

In terminal ,  run this cmd ::  

fsck.vfat -tr  /dev/sda1

Seems , Some blocks of  EFI partition had got corrupt.

 

 

Thanks for the help.
