De Resolvendo o temido erro do Windows 8 0xC0000225 :
I've had this happen to me twice, all of a sudden Windows 8 refuses to
boot and gives an error code of 0xC0000225 (or something) and anything
you do won't fix it. The problem is that since for whatever reason
Windows thinks there's no bootloader, it refuses to boot. Period. You
can't even go into the recovery environment, which is my biggest
complaint at Microsoft.
In any case, there's one way I've found to resolve this. If you have
access to another computer, take out the affected computer's primary
drive and find a way to mount it in the system (internally,
externally, whatever). Then do the following:
- Open command prompt as an administrator
- Type in "diskpart"
- Type in "list disk". Find out which disk the affected drive is.
- Type in "select disk #", where # is the affected drive's number
- Type in "list partition", find the partition number of the system partition (it's usually 100MB, 200MB, or 300MB), then type in "select
partition #", where # is the system partition's number.
- Type in "assign letter=z", assuming you don't have a Z: drive.
- Exit out of diskpart by pressing CTRL+C
- Type in BCDBoot
[Drive letter of affected drive's Windows partition]:\Windows /S Z: /F UEFI
So if the affected drive's
Windows partition is say G:\, you would type in BCDBoot G:\Windows /S
Z: /F UEFI
It should fix the bootloader. If you can get into a recovery
environment on the affected computer, then this should work as well.
