I recently migrated to Linux Mint and I am trying to install Windows 10 but the VirtualBox is stuck on the Windows logo. I downloaded the ISO from Microsoft. I have allotted 3.5 GB RAM to the VM.
The original post is about Linux Mint, but seeing how the other 3 threads link here and this being the first hit on Google when searching for this specific problem I'll leave my comment here
I was trying to create a Win10 VM on a Win10 machine, but I was getting stuck on the install. Tried all of the above, but to no avail. The problem turned out to be that Intel Virtualization wasn't enabled in BIOS. After that I could enable VT-x/AMD-V ( Settings > System > Acceleration ). Not sure if you need Hyper-V disabled, mine was already turned off.
If anyone comes across this question as I just did... I tried this on three different mint installs, thinking if I could get it to work on one, I could just transport the finished VM. NONE of the three worked. So I worked my way thorugh proposed solutions until removal of USB worked. So I got curious and just tried a different USB controller, set it to 2.0 and it worked as well, tried it on the other systems and same results on all three. USB3 was default, I guess this happens when you install the extension pack? So consistently I did not have to remove USB, I just set it to USB 2.0.
Installing w10/1909 on mint 18.3 and 19.3, virtualbox 5.1.38_Ubuntu r122592
In my case it was stuck during install. I just needed to enable EFI in
Settings > System > Enable EFI (special OSes only)
Not sure if it's the right way to proceed (especially due to the note about "special OSes"), but seems to work so far (you just need to press a key to boot on the installation media at boot time the first time).
