If I enable UEFI in BIOS then the message from BIOS is that there is no operating system on this computer.
This is an Acer Aspire V 15 Nitro Black Edition.
Sorry my dyslexia kicked in... a GruB is the linux version of WBM... it picks what system to boot too.I am not sure what grup is but I can't boot Windows so how do I make that shortcut?
I am assuming you changed from GPT partition to MBR? But the thing is if you install Windows in UEFI mode (or if it was preinstalled that way - very likely), you will end up having problems with dual boot. As far as I know, you need to have them both installed in "Legacy Mode" for dual boot. You can use something like grub loader to determine which OS will boot on startup, or alternatively, change the boot order in the non-UEFI BIOS for multiple drives. The thing is Windows has been optimized with "Secure Boot" and all of that in UEFI so that it boots faster than in non-UEFI mode. I can't say you'd notice a terrible difference since you got it working.OK, now I can finally boot Windows.
After trying lots of tutorials (on the Linux side and the Windows side), after trying Microsoft's own recovery tools, my employer bought a tool for some $40 and it managed to make Windows to boot from MBR.
When I tried Microsoft's own recovery tools (both for UEFI and MBR) they reported that they found a Windows installation and it is in good condition and they reported that they successfully repaired it. However, when I tried to boot the message was: "Missing operating system", so I was still stuck.
Then I used the tool bought by my employer. I don't know the name and if I posted the name it would probably be considered spam advertising. If you want to know the name, PM me and I will go ask the admin. The funny thing is that this tool was a live FreeBSD image with LXDE and it succeeded where Microsoft had failed.
So now Windows is able to boot from MBR with UEFI disabled.
Ubuntu installs fine in conjunction with the Windows 8 Secure Boot. I have not tried running it on a laptop, but I have an All-in-One which uses the Nvidia mobile driver and will swap GPU depending on the situation and I notice there is a version of that driver for Linux x64. Maybe Optimus does more and I am just not aware.But UEFI is totally new to me and it seems to me that Microsoft not only did not make any effort to make this UEFI crap nice to other operating systems but I feel like Microsoft did everything they could to prevent users from installing other operating systems.
I am not encouraging you to use Linux, just anticipating you probably will.But I find your attitude very interesting. You are encouraging me to try Linux again even if you seem to be a Windows guy (based on your profile). The opposite is not very common on Linux forums where the Linux guys encourage you to leave Windows and use Linux.
