A tip for running Win8 or 10 in Oracle Virtualbox, that I've discovered tinkering around with Windows OS guests on Linux hosts ...
Untick the 3D-effects option, when installing either of these OSes as a Virtual Machine, to remove the problem of a flickering graphics display and/or lagginess - it seems that Virtualbox's graphics software has difficulty with the 'metro' desktop of icons & tiles in Win8 & 10.
This display/lag issue doesn't seem to present itself with a Win7 guest, when the 'experimental 3D effect' option is ticked. That said, I've never found any advantage of having the 3D option ticked, as games wont play and the 'aero' effect (taskbar transparency) doesn't show in VM ...
To run VMs well, you'll ideally need a 4-core machine, with dual-threaded CPUs.
Hope this helps

64bit OS (32-bit on Samsung[i] netbook) installed in [i]Legacy mode on MBR-formatted SSDs (except pi which uses a micro SDHC card):
2017 - Raspberry pi 3B (4cores) ~ [email protected] - LibreElec, used for upgrading our Samsung TV (excellent for the task)
2012 - Lenovo G580 2689 (2cores; 4threads] ~ [email protected] - LL3.8/Win8.1 dual-boot (LL working smoothly)
2011 - Samsung NP-N145 Plus (1core; 2threads) ~ Intel Atom [email protected] - LL 3.8 32-bit (64-bit too 'laggy')
2008 - Asus X71Q (2cores) ~ Intel [email protected] - LL4.6/Win8.1 dual-boot, LL works fine with kernel 4.15
2007 - Dell Latitude D630 (2cores) ~ Intel [email protected] - LL4.6, works well with kernel 4.4; 4.15 doesn't work
