Re-partitioning causes Booting issues

I removed the second HDD..Since I have two similar at first removed the OS drive but later put it back in while removing the secondary drive.

Startup repair could not automatically repair ..Said some program driver needed to be changed but didnt specify. However simple reboot got me to login to windows straight to desktop !

Ive created a restore point and am going to use mclarium to create a disk image.

Would you suggest I reboot multiple times to check if things are in order?. I want to also schedule a disk check.
Secondly can I now safely put back in my second drive?

Hmm, you could try putting it back in after Macrium imaging.

If it fails perhaps boot order has changed? 2nd HDD was already formatted, right?

Disk check - Disk Check

I did create two new partitions with minitool
Data is also cleaned up.
Just wondering if the problem starts after inserting the other drive do I go into disk part and Clean it ?

Lets see after you try again :)

Well the same problem as soon as I insert the data secondary disk.

The non OS drive gets labelled as boot manager and the boot also doesn't work if I change the drive boot sequence in bios
I'm sure something got messed up in mini partition usage

Do try clean in diskpart - Disk - Clean and Clean All with Diskpart Command
Make sure you don't clean your OS drive

Used diskpart to Clean. Rebooted same issue. Went to BIOS booted by clicking boot from EFI filesystem.
Startup repair run and as usual runs for sometime and doesnt fix anything.
Force restart and the laptop boots normally :)

Went to disk management and formatted the second drive as GPT as well. Works well now. No issues as such except the boot sequence doesnt have an entry for the second HDD. Not that it matters since the HDD is a not OS drive.

Thanks Gokay !!

If it works.. :)
