MBralign Windows 2008

c_delporte — Thu, 05 Jun 2025 07:28:49 GMT

After a succefully P2V converter 4.0.3.62417 and a succefull mbralign operation

Windows failed to start with message File:\windows\system32\winload.exe status 0x0000225

Of course, boot sequence on the vmdk backup is ok.

Does Mbralign 1.4 support Windows 2008 ?

Thanks Christophe

You shouldn't need it on Vista/2008 as the the default offset is 1MB (1024KB), a value which should result in aligned VMs.

Ditto -- use mbrscan (installed as part of the ESX Host Utilities) to check/verify -- do make sure you've installed the ESX Host Utilities of course.

No mbrscan tell us that Windows 2008 must be aligned.

An amelioration may be that mbrscan return that Windows 2008 don't need alignment. What do you Think about this ?

Hmm....I'm afraid I'm not following -- could you post the mbrscan output by any chance?

I've encountered a bunch of 2008's aligned to offset 32256 and had the same problem with a broken boot loader sequence after running mbralign.

However, it can be easily fixed by rebuilding BCD store: http://support.microsoft.com/kb/927391/en-us
