Laptop Model - Asus Vivobook s14, 256GB SSD + 1TB HDD i7- 8th gen, Nvidia Mx150, Windows 10. I'm trying to dual boot my device with Ubuntu 18.04LTS, I partitioned 100gb in my HDD. but the bootable Pendrive is not detected. I tried with the same with my old laptop which detects the USB for boot. I disabled secure boot, fast boot, Intel RST. I don't know where the issue lies. Rufus MBR MS Info

  • What tool did you use to make your installer USB? Try Etcher, if that does not work, try Rufus UEFI: https://askubuntu.com/questions/1278772/unable-to-access-ubuntu-from-uefi/1278841#1278841 – C.S.Cameron Oct 09 '20 at 04:23
  • I tried both Etcher and Rufus. And Rufus is not giving me an option to change the partition scheme. It is fixed at MBR. – Sankeerth Oct 09 '20 at 07:53
  • What do you see when you select Partition scheme as in the image below? Target system should change automatically when GPT is selected. F8 should allow changing the CSM / UEFI mode when booting. Turn off Secure Boot. Confirm Windows is also booting UEFI. – C.S.Cameron Oct 09 '20 at 08:56
  • Secure Boot is disabled as I mentioned in the question. Partition Scheme is Fixed at MBR I'm Unable to change it to GPT. Windows is booting in UEFI mode. I tried updating BIOS which looks like it is in Legacy Mode but it says it is already in the Recent Version. I Still cant find the problem.I attached Rufus and MSInfo images in the question, I still can't boot through USB. – Sankeerth Oct 10 '20 at 03:47
  • Does it make a difference if you select quick format? Have you seen this: https://www.infofuge.com/asus-vivobook-s14-s406ua-boot-from-usb/ – C.S.Cameron Oct 10 '20 at 04:16
  • Quick format doesn't help. I also tried with older versions of Rufus, but no use. I can't change the partition scheme using any method. – Sankeerth Oct 10 '20 at 10:24
  • Have you tried making the USB as UEFI using your old computer, or another computer that will allow the GPT scheme in Rufus? Have you tried 20.04? – C.S.Cameron Oct 10 '20 at 10:40
  • I did as you said, made it GPT and UEFI, but still, it doesn't recognize the USB. – Sankeerth Oct 10 '20 at 15:55
  • Can you describe in more detail what you mean by "doesn't detect pendrive"? E.g., does it not appear in the list of bootable devices in the BIOS menu? If you doubt the pendrive can be detected, try making it a Recovery Drive for Windows (you can do that from inside Windows) and then try to boot with it. If it works, then it is obviously not a problem with the pendrive. Some BIOS systems are tricky with secure boot - they require a supervisor password to be set before they REALLY allow secure boot to be turned off. I think that may be deliberate "security through obfuscation". – Craig Hicks Oct 13 '20 at 08:09
  • Pendrive doesn't show up in the list of bootable devices. The Pendrive is absolutely fine because I can boot it on my older laptop. Secure Boot is turned off along with fast boot. but BIOS doesnt show the option of CSM. – Sankeerth Oct 13 '20 at 10:41

Finally, I installed Ubuntu after trying for very long time.

  1. I changed the partition scheme to GPT in rufus.
  2. I enabled mass storage in bios.
  3. I tried downloading the ubuntu image again.

I don't know which of the following helped, but I was able to install ubuntu and now its running smoothly. Thank you everyone who tried to help.

Rufus Settings for UEFI Only Ubuntu Install

In BIOS select Security tab then press the Secure Boot Control button and Disable. Select the Save & Exit tab, then Generic USB Flash Disk 0.00

Note Partition scheme and Target system for UEFI only install.
