PENDING Operating system not found after OSD Deployment

[maverickIT]

The task sequence says the OS applied succesfully then after it reboots, I get an error that, the Operating system wasn't found. Hence no SCCM client installation takes place. I ran "BCDBOOT C:\windows /S C:" by getting into WINPE , then the OS worked fine . This happens with both WIN7 and WIN10 . Using SCCM 1902. Any known issue . Attaching SMSTSLog from "C:\_SMSTasksequence". Please share your inputs.!

I've had that issue when it can't find the boot device which in our case always happend with older hardware when trying to use UEFI. Switching to legacy Bios fixed that for us.

I tried both UEFI and BIOS but no fruitful results, finally went ahead with adding cmdline in task sequence as " BCDBOOT C:\windows /S C: " . the OS deployment got completed . however, the tak i.e client installation on the PC during OSD takes more than longer time . Overall, each deployment takes around 50 minutes , weird thing what I noticed is , the delay is happening only during the client installation step . Any suggestions ?
