The different causes for these errors are either the winload.exe file is not accessible or is corrupt, or the boot location for the operating system cannot be located.

So I removed the old WD entirely and then Vista's boot loader failed, with "0xc000000e Missing or corrupt \windows\system32\winload.exe".<BR><BR>What else do I need to do to get Vista booting off ...

Fix Error 0xc0000185, 0xc0000225, 0xc0000001, 0xc00000f, 0xc000000e, A required device isn’t connected or cannot be accessed on Windows 11/10.
