Fix: Can't Install Windows 10 on VirtualBox

If you want to try Windows 10 Technical Preview, but you don’t want to uninstall your old operating system, using VirtualBox to create a virtual machine on which you can install it is probably the best solution. But some users have certain problems with installing Windows 10 on their virtual machines, as they reported that they’re constantly getting 0x0000005D error when they try to boot from ISO.

Check for the Latest Version of VirtualBox

First thing first, make sure that you’re using the latest version of Virtual Box, because older versions are probably not compatible with Windows 10, so you won’t be able to run it, or even install it. Perform an update check inside Virtual Box, and if your version is outdated download the latest version. If your version is up to date, than problem is not in the compatibility of Virtual Box with Windows 10.

Disable Floppy Drive and Change The Pointing Device

As you maybe noticed, Windows 10 Technical Preview is not compatible with touch input, as well as with floppy drive. This may be the problem of getting the error, so disable floppy drive and change pointing device, and see if your simulation of Windows 10 works good now. To do so, follow these steps.

Go to Settings in VirtualBox
Go to System and then to Motherboard

Under Boot Order, uncheck Floppy and Network
After that, set your pointing device to PS/2 Mouse
Click OK and restart VirtualBox

Also, it wouldn’t do harm if you go to General and check if version of your system is Windows 8.1. In case the version is “Other Windows,” change it to Windows 8.1. This also could be the cause of your problem, because some users have reported on VirtualBox’s forum that they accidentally left their version of the system to be “Other Windows,” and after they changed it, the system worked normally.
