utilizing both Fat32 and NTFS partitions on that USB, that I can switch between them ( windows sees only one at a time ) with a single press of a button.

#Ubuntu 14.04.2 add noapic boot option drivers#

With the aid of Easy2Boot I got a 32GB USB3.0 with win8-10 installation disks + k/ubuntu + remix OS +hole set of portable tools for backup/recovery/benchmark/get info/ etc & an iso of ~7GB full of latest drivers for win xp-10. and it can even support UEFI boot as well ! ( for that you need to make spacial file from the ISO of that OSs )

I suggest you start reading about the FREE Easy2Boot toolset that can SAVE YOU a VERY LARGE HEADACHE and TIME, as it allows you to boot many installation disks of many different OSs, like windows, ubuntu etc. It is much cheaper to invest in usb, as you can rewrite on it, time after time, much more times then RW CD/DVD, and it is much more secure and less prone to 'errors' due to heat/light/kinetic or magnetic damage.Īlso, if you need many OSs installation disks on that USB, invest in a large capacity usb (32/64GB) and make a multi-boot usb from it. Invest in some fast write speed USB3.0 flash disk, and 'burn' the OSs installation disks onto the USB.

why don't you think to use USBs for that ? In spite of your wish to cd-rom boot OSs. the BIOS/CSM option is just emulation of BIOS ). ( the 'bios' of modern laptops got UEFI as prime basic IO system. In the 'bios' when CSM option is ON -> BIOS legacy mode enabled -> both UEFI and BIOS boot method allowed. In the 'bios' when CSM option is OFF -> UEFI mode -> only UEFI boot supported. There's a good chances that your CD/DVD you use is just not bootable, thus the UEFI doesn't even look at him. You can also use a program like Macrium Reflect Free to clone the Windows portions of the drive onto a GPT UEFI formatted drive. An Asus Backtracker flash recovery restore will also do the same as the F9 reset. You want to create a GPT UEFI disk boot to get back to the original config. It sounds like you may have blown away your recovery partition, but if not you could back up all of your stuff and do a from power on F9 reset to reload the OS in the out of the box state. You could try re-installing the BIOS, using Winflash under Windows to schedule the flash at next boot - and using the /nodate option - you can flash the same or older BIOS. I assume you used 'Restore Defaults'? F10 and reboot?

With Windows 8 as host (so the brightness is controlled by windows), so the problem was solved.Īs things were, there was no need for a boot manager (GRUB) but the boot option for Ubuntu, wrongly, is still there.Īlfredoasus, this is why I use Windows 8.1 host and Linux VM guests.

#Ubuntu 14.04.2 add noapic boot option install#

Well, the solution I've found to continue with my beloved KUbuntu was to install it as a guest in Oracle's VirtualBox I did many research to solve this problem but without success. To do this I had to change the boot sequence in BIOS which worked perfectly.īut, there was a problem in controling the screen brightness from Ubuntu. The 1st thing I've done was installing KUbuntu 14.04 using Ubuntu boot manager (GRUB) along with Windows. The CD-ROM option simply disappeared from BIOS at its own will.Ī few months ago (+/- 5 months) I received a brand new machine (this very one) with windows 8 (OEM). I've done your tip, it really did what you said.Ģ-Ubuntu in ssd (<= this also is an error because there is no Ubuntu in SSD)

My next task should be to install Mac OS x in VirtualBox (Windows 8.1 as host) but the way things are I won't.Īlfredoasus, from power on, start tapping the ESC key immediately after pressing the power on button, until you get the Boot Menu, then select your Optical drive to boot from it. I've seen also that when you're adding a new boot option the BIOS program asks which directory is the *.EFI file that defines that device but I've seen that you can delete/add boot options but I haven't done anything like that and it disappeared by itself.Īnd now I'm not able to recover it. The last boot sequence remained in BIOS until the next change. I've changed the boot sequence many times in older machines and forget about it.

In older machines that change remained between boots. In this machine, I've already changed the boot sequence a few times mainly to install new OSs.Īnd every new OS to install I had to make the change again and again. Prostar - Yes, that is the case, but without my intervention. In UEFI BIOS setups, boot options can be removed (this has gotten some users into trouble). Perhaps the CD/DVD-ROM entry was deleted(?).
