@prasunthapa Thank you for choosing McAfee Support Community

Can you check and let us know whether Fast boot is disabled in Bios & also Fast Startup status in control panel.

Also check whether BIOS and Firmware is running in latest version as per vendor release.

if the issue repeats please log a case with McAfee Technical Support for assistance.

Re: Windows boot Issue on Win 1903 DE 7.2.9

I had this issue with several systems in my environment with 1709 and we discovered its due to boot partition corruption. The fix was to decrypt the disc offline using DETech and then using a Windows disk or MS DaRT disc run command prompt following the below instructions.

Run DISKPART
DISKPART

List disks if there are multiple disks
LIST DISK

Select the primary disk
SEL DISK #

List the volumes and partitions to see the EFI boot partition
LIST VOL

Select the EFI partition which should be Fat32
SEL VOL #

Assign it a letter
ASSIGN LETTER=F:

Exit the DISKPART
EXIT

Change disk to the assign partition
F: or cd F:

Format the EFI Partition
format F: /FS:FAT32

Fix the boot settings
bcdboot C:\Windows /s F: /f UEFI
