(SOLVED) Question Trying to install ubuntu, Get stuck on GNU GRUB screen Question My next Linux Ubuntu build, expensive but not nuts? Question How do I Install Ubuntu on a specific HDD partition? Question Is efi partion needed for dual boot for ubuntu installation This latest VM is current and up to date on the Ubuntu side. Is this more likely a fault of Virtual Box, or something going on with the install? I absolutely have been monkeying around inside it trying to teach myself things in a way that is easy to wipe and reinstall, which I have more than once. I have it physically loaded on one machine here (a 3rd gen Intel OptiPlex) and have no issue with it, and have loaded it on a small handful of other similar machines up to 4th gen with no similar issue. I have been using the VM as a test bed of sorts so I can learn a bit about it in order to migrate some work machines to it. Almost without fail I can power off the VM and start it again and it will be back to the larger resolution but don't always stay there.

Lately I have run into an issue where when I start the VM, it goes to the load/splash screen in 'switch mode' (which is a full windowed screen at 1980x1440 4:3) will start to the desktop, then flashes a few times the end of which it defaults back to 800圆00 resolution.ĭue to the way the menus work, sometimes I can 'grab and move' the setting screen enough to both change resolution and hit the apply button. The host system is running fine, no issue there. I am running Ubuntu 20.04.4 LTS inside Virtual Box 6.1.
