This article is specific to Windows 7 but similar errors occur on all versions of windows. NOTE: You will need your Windows 7 DVD or a USB with the recovery console installed. IF USING A USB STICK MAKE SURE IT IS PLUGGED INTO A USB 2 SLOT, USB 3 IS NOT SUPPORTED; It will error with ‘failure when attempting to copy boot file’. After rebooting your computer you receive the following error: Windows Boot Manager Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1.insert windos cd and run a repair your computer option. File: /boot/bcd Status: 0xc000000f Info: an error occurred while attempting to read the boot configuration data. You may receive a similar error which lists the error code as 0xc0000034 or missing file: windows\system32\winload.exe instead. You may also receive further errors after trying to repair the bcd store using bootrec and bcdedit as follows. The requested system device cannot be found. The “Windows Boot Configuration Data File is Missing Required Information
You receive the error "A required CD/DVD device driver is missing" when installing Windows 7 or Windows 2008/R2 from a USB device. Furthermore if you browse to install drivers you will see that your CD/DVD drive is actually installed successfully. You are using a USB 3 Port The error is very misleading; the problem is not that the CD/DVD device drivers are missing, it is that USB 3 drivers are missing. Most likely you have plugged your USB drive into a USB 3 port but the problem here is that Windows 7/2008/R2 doesn't ship with USB 3 support. The solution is very simple; just plug your USB drive into a USB 2 port and start the install again. Why does this happen? The initial boot up will work fine but once Windows starts installing drivers it will fail for the USB 3 hardware. At this point the installation can no longer see the USB pen resulting in the error. By booting up on a USB 2 port Windows has the required drivers to continue the installation successfully. As for the "A required CD/DVD device driver is missing" error I can only guess this is because the install expects to be
Most of you reading this will no doubt already have some idea of how file permissions are handled when moving or copying files to and from NTFS drives. The following behaviour is expected: When copying a file from one NTFS volume to a folder on another volume the file inherits the permissions of the destination folder. When copying a file from one folder to new a folder on the same NTFS volume the file inherits the permissions of the destination folder. When moving a file from one NTFS volume to a folder on another volume the file inherits the permissions of the destination folder. When moving a file from one folder to new a folder on the same NTFS volume the file retains the permissions.
This only applies to you if UAC is enabled and users are a member of the local administrators groups. I was doing some work recently for a client when I noticed that a login script was failing to map network drives if deployed through group policy. The strange thing is that if I ran the script manually it worked. Also, at other sites this same login script works perfectly fine whether it’s run by itself or deployed through group policy. The only difference I could find was that users were local admins at the site where the script fails. When users are local administrators UAC comes into play.
There are different reason why you may get an access denied error 0x80070005. This particular one and the following fix is only applicable when the following is met: Your operating system is Windows Server 2008/Vista. If it is Windows 7 or 2008 Server R2 then this fix does not apply. You have no other problems at all with shadow copies/previous versions. It works perfectly fine accessing previous versions of all other folders except just one (or a few) folders. UAC (User access control) is enabled. More info about UAC can be found here. You are logged in as an Administrator who should be able to access these folders/shadow copies. The error is caused because of a bug in Windows Explorer and how it handles UAC. It is exactly the same reason as to why you get an access denied message when trying to access certain folders you should have access to. In these scenarios you have given the administrators group full control of the folder, you are a member of this group but you still get an access denied message. See the following UAC access denied for the cause and fix. It talks about Explorer having problems accessing certain folders.
The Problem You receive a Windows 7 access denied error when accessing a folder through Windows Explorer even though you have set the permissions correctly. You are an administrator and the administrators groups have full control over the folder but you can’t access it without Windows re-writing the permissions. The cause of this is because of a new feature in Windows 7 called User Access Control (UAC). It is the combination of UAC and a bug in Windows Explorer that causes the access denied error. The easiest solution is to simply disable UAC. If this is not possible (for security reasons) then read on for alternatives.
