I am trying to install Manjaro for the first time on a Lenovo Yoga 500 14ISK laptop. It has currently Ubuntu and Windows dual booting, and I would like to replace Ubuntu with Manjaro eventually, but right now I couldn't even boot from the usb installer: namely, if I select the USB stick from the quick boot menu, my computer goes straight to GRUB after a few seconds. I seem to have exhausted the previous posts in this topic, that's why I'm starting a new thread, but apologies if I missed something.
Also one more notable circumstance is that due to my own folly, I have forgotten my bios administrator password some time ago (and to my best knowledge it cannot be reset on this machine), so my options are limited in that domain. However, I seem to have fulfilled all the requirements for the installation:
- Verified ISO file both with SHA1 and SHA256 checksums
- Disabled secure boot using
mokutil --disable-validation(Now the first thing that my computer shows upon startup is "Booting in insecure mode", so I think this worked properly)
- Checked that my Ubuntu installation is indeed UEFI
- Checked that my hard drive is in GPT mode using
sudo gdisk -l /dev/sda
- Tried both Manjaro 20.03 XFCE and Manjaro Architect
- Tried the USB stick on a different machine (and it worked)
- Tried writing the installer to the USB both with
dd, Etcher and Rufus (in
One thing I could not check is whether fast boot is enabled. I think I disabled it during the Ubuntu installation a long time ago, but I am not 100% sure and I could not find a terminal command to check that without going into the UEFI settings.
Also one weird thing is that the desktop I tried the usb stick on displayed two options in the boot menu for the usb stick, one UEFI and one not; while my laptop only displays a single option for the usb (uefi or else is not indicated).
What else should I try to be able to boot from the usb? Thank you in advance!
