We have played smoothly Steam games with our Ubuntu setup. Now it is time to jump into racing games and we have decided to build 3 monitor racing sim.
Question is that is this possible with Ubuntu or is this Voyage into the Unknown (spectrum48)? Yes, I am that old…
If anyone has done this successfully, please do let us know. Any tips and help is appreciated.
If this is still not easy/possible then we just buy one extra SSD and Win11 for this. Just to say that we are not that interested to use iRacing, at least at the moment.
After thinking this we decided to go to two SSD option. One for Ubuntu and one for Win11, choosing which one to load from UEFI boot partition.
Now, we have existing Ubuntu SSD. When we install Windows is it OK just to remove Ubuntu SSD and insert empty SSD for Windows and install Windows? When installation is done then just insert Ubuntu SSD back to PC.
Does EUFI automatically recognize both OSes if done in this order? Is it possible to choose priority OS from BIOS boot sequence?
Or should we first install Windows and only after that install again Ubuntu from new?
Yes, assuming your UEFI firmware behaves correctly
Yes
No, not necessary
If only one target disk is available during the installation process, then other disks are unaffected.
When you attach a second disk and power on, the UEFI firmware should do its job and recognise both disks.
An important detail is that both Windows and Ubuntu are installed in UEFI mode and both disks have their own ESP, which allows independent operation.
I have now proceed with this matter. Windows 11 has been installed to another SSD and Ubuntu is in another. PC now startup automatically to Windows 11.
I am now trying to fix GRUB so that in startup we can choose which OS to load. I made bootable Ubuntu stick and started it. In terminal I tried
sudo grub-install /boot/efi
and get grub-install: error: cannot find EFI directory.
I DDGed internet, but did not find anything useful. So, my question is what to do now to fix GRUB?
If Grub was working before, do not reinstall (and your attempt was incorrect, BTW).
As always, after installing Windows in this context, you need to open UEFI settings > Boot and change the boot order back to Ubuntu. Then boot Ubuntu and run sudo update-grub
Your UEFI settings control which disk boots first.
As mentioned by @celticwarrior , access your UEFI boot menu (not Grub) using your PC dedicated key.
Do you see entries for both Ubuntu and Windows?
