I am trying to install Ubuntu 18.04 on a brand new Acer Swift 5 (2019) using a USB flash drive. After the grub menu and the selection of keyboard, WiFi, etc., I get to the Installation type screen of the Ubuntu installer and there are no options there.

see picture here

Clicking on anything freezes the system and I have to restart by holding down the power button.

Error messages when trying Ubuntu from the USB flash drive:

  • Did you verify your ISO to ensure it was perfect after download? (tutorials.ubuntu.com/tutorial/tutorial-how-to-verify-ubuntu#0) and then validate the write to your install media to ensure it was flawless? (help.ubuntu.com/community/Installation/CDIntegrityCheck where CD refers to any install media, cd/dvd/hdd/ssd/thumb-drive/flash-card/..)

  • Thanks. The flash drive with iso was prepared by the it help desk where I work so I assume that they did it properly? Also, the flash drive works fine under "try Ubuntu" mode. Doesn't this mean that the ISO is fine?

  • The 'try ubuntu' doesn't verify the whole unless you used every option/application/etc, and verified for no squashfs errors in the logs & actually run the installer as well; no it means little (a single bit wrong can mean install shouldn't be trusted, try ubuntu won't have tested 100% of media). The lack of install media in your picture could mean a kernel module (driver) is required to be added, but that's a waste of time until media has been verified; the freezing makes flawed media the more likely cause in my reading.

  • ps: note I don't know your equipment so that is not taken into account in my 2c worth.

  • Thanks again. I tried "try Ubuntu" once more and saw that there were a few errors that went flashing by. I could only capture them on video although not very clear. ACPI BIOS error (bug): could not resolve symbol... ACPI error aborting method... *ERROR * discarding overwritten... See also the attached image in the edited original post.

It turns out that the problem was not the ISO or how the USB stick was prepared in Rufus. I had to change a few things in BIOS, namely:

  • Changed BIOS to UEFI
  • Disabled secureboot
  • Set superuser password
  • Changed SATA to AHCI mode. This was the trickiest part as the option was hidden in the BIOS menu. It became available by hitting ctrl-s once in the appropriate BIOS menu.
