Hi there.
Unless you really need to mess around with specific hardware why even bother with dual booting. Choose what OS you want to be your PRIMARY OS (i.e the one you most use) and then create the other OS as a VIRTUAL MACHINE. Easy enough to do with things like VBOX / VMWARE.
These days the overheads of using a VM are fairly minimal so I'd leave Dual Booting unless you really have to do it.

My laptop is not so good, and I tried VM but it's just too slow
Since I got rEFInd to work with Windows and Ubuntu, I will be leaving it like that without removing it,
but I will keep thein a safe place for later :)Code:sudo rm -r /boot/efi/EFI/refind
Excellent news :)
One thing to be aware of is Windows sometimes likes to take control of the boot manager.
If you do an upgrade to a new version of Windows it may well reset the default boot manager in the firmware to be \EFI\Microsoft\Boot\bootmgfw.efi (which is the Windows boot manager). This is nothing to worry about and doesn't mean anything is broken or your Linux install is lost but you'll boot straight into Windows instead of seeing the rEFInd screen at startup.
To set it back to rEFInd you can either re-install rEFInd or (more simply) from Windows command prompt enter bcdedit /set {bootmgr} path \EFI\refind\refind_x64.efi
Hi there
I have to totally disagree here --CAD runs fine in a VM - enable hardware acceleration and 3D in the VM -- even a laptop with a decent i5 or even i3 CPU will be OK. VM's these days can run at almost 100% Native speed - especially if you have enough RAM and CPU power - and even better if you can stick the VM on an SSD.
Some really intensive GAMING might not be suitable for a VM - although that's improving - especially if you can set a VM up to use the separate graphics GPU card directly (Pass through) .
If the VM can't cope with your CAD it's probably because you either have very SLOW HDD's (will kill any system) or you haven't set up the VM properly.
I run a whole slew of different types of hardware on VM's - for instance a record VINYL creating studio on an XP VM, an old HP plotting machine, an archtects blue printing machine and a dedicated 35 MM negative scanner to digitise old negatives (quite a CPU intensive application) on VM's without any problem.
@mibaup glad you got your problem solved. Don't discount though in the future the power of using VM's. !!

Hi there
That's good
But pushing the VM thing again you can run a VM in UEFI mode even if your Host machine is BIOS only -- so ideal for testing - even on old machines. These days the "Virtual BIOS" in virtual machine software has a huge amount of flexibilty as well as options in the Virtual Machines configuration file.
Makes it easy if you want to use the VM on different computers for example without the hassle of re-installing the OS again -- you can have the SAME VM (data disks etc) whether the HOST is Windows or Linux.
