[SOLVED] Windows 10 PhysicalDrive VERR_ACCESS_DENIED

[ww9rivers]

Edit:  I'm embarrassed to report that this was actually a problem I have had before: To use a physical drive, VirtualBox must be run as "Administrator". I have previously configured that in the VirtualBox properties. Overtime, I have forgot about that little checkbox. ---- I've been running VirtualBox on Windows 7 Enterprise for some time. Recently I upgraded to Windows 10 Enterprise, and VirtualBox started to fail. The VBox.log file is not saying much: Code: Select all VirtualBox VM 5.1.30 r118389 win.amd64 (Oct 16 2017 10:47:00) release log 00:00:02.453450 Log opened 2017-11-11T23:30:01.747131200Z 00:00:02.453451 Build Type: release 00:00:02.453454 OS Product: Windows 10 00:00:02.453456 OS Release: 10.0.15063 00:00:02.453457 OS Service Pack: 00:00:02.521139 DMI Product Name: HP EliteBook 8470p 00:00:02.524571 DMI Product Version: A1029D110C 00:00:02.524581 Host RAM: 16247MB (15.8GB) total, 8399MB (8.2GB) available 00:00:02.524584 Executable: C:\Program Files\Oracle\VirtualBox\VirtualBox.exe 00:00:02.524584 Process ID: 14380 00:00:02.524585 Package type: WINDOWS_64BITS_GENERIC 00:00:02.525324 Installed Extension Packs: 00:00:02.525348 None installed! 00:00:02.525809 Console: Machine state changed to 'Starting' 00:00:02.526109 Qt version: 5.6.2 00:00:02.527822 Console: Machine state changed to 'PoweredOff' 00:00:02.529468 GUI: UIMediumEnumerator: Medium-enumeration finished! 00:00:02.529532 GUI: Show mini-toolbar for window #0 00:00:02.531300 GUI: Adjust mini-toolbar for window #0 00:00:02.531335 GUI: Map mini-toolbar for window #0 to screen 1 of 2 00:00:02.531358 GUI: Resize mini-toolbar for window #0 to 2048x1152 00:00:02.547559 Power up failed (vrc=VINF_SUCCESS, rc=E_FAIL (0X80004005)) 00:00:02.885675 GUI: Aborting startup due to power up progress issue detected...

Thank you very much for helping.

It would have failed this way on 7 as well. Sector level access to physical drives is restricted, even for admins. There are system and registry tweaks which can override.

Why do you need raw drive access anyway? Why not simply locate a VDI on the drive?

It had been running under Windows 7 fine till the upgrade.

I need physical drive access because my Linux system is installed on a physical drive. Plus, I want to be able to boot into Linux on that drive some times.

Past discussion, enabling raw access to Win7 and later disks. AFAIK this is still the solution (though raw access is not something I use myself) :-
