BootCamp Corrupt

[Apple Mac Daz]

I have windows 10 installed using bootcamp
when i try and boot windows i just get the following message

bootmgr image is corrupt. the system cannot boot

I have removed the bootcamp partition and gone through installing bootcamp again.

it partitioned the drive installed win 10 and on first reboot got bootmgr image is corrupt again

seems some how my hard drive is all messed up

If i go in system preferences / startup disk bootcamp isn’t even listed

if i power on the system and use the options key i have windows listed

is there anyway to fix all this or is it better to just wipe the full system and reinstall Catalina and bootcamp
