“Damn, I’m good” (c) Duke Nukem.
I think I’ve finally cleared the topic about recovering boot sector in Windows machines. I mean, there wasn’t any big mistake, but let get things clear – this is a co0l topic for IT helpdesk and to gain some money ’cause users cannot fix this by themselves. SO… with the Windows 8.* boot failures there’s one good method to rescue the environment. If you had read my post before, you can also try to do this:
Clear the RO if you cannot bootrec /rebuildbcd:
diskpart select disk {disk_number_here} attrib disk attrib disk clear readonly
Clear the RO from volume also:
diskpart list vol sel vol {vol_number_here} attrib vol attrib vol clear readonly
And finally you can run:
chkdsk {sys_drive}: /r /x /f
Of course the error could be strongly related to Windows Registry, so basically a backup (if exist) can work!
{be_on_the_system_drive} cd windows\system32\config ren default default.old ren sam sam.old ren security security.old ren software software.old ren system system.old cd regback copy default {sys_drive}:\windows\system32\config copy sam {sys_drive}:\windows\system32\config copy security {sys_drive}:\windows\system32\config copy software {sys_drive}:\windows\system32\config copy system {sys_drive}:\windows\system32\config
Finally:
sfc /scannow /OFFBOOTDIR={sys_drive}:\ /OFFWINDIR={sys_drive}:\windows
{sys_drive} is usually c.
