  • Solution: 1. Enter BIOS, set supervisor password 2. nvavigate to main tab, press ctl+s 3. change SATA mode to AHCI 4. Reinstall Windows from bootable USB 5. Install Ubuntu without any problems Thank you guys for your replies, especially @JordanB. Your post about RAID led me to victory :D
  • So, the problem was with that weird RST Optane mode (don't know why it's here with my ssd drive), changed to AHCI and Ubuntu finally discovered SSD. The problem is, now Windows is not able to boot :((( It's high time to reinstall Windows omitting that Optane ***** and then install Ubuntu.
  • Ok, first of all, I'm sorry for not responding- a lot of work... @JordanB, SATA is not in RAID mode and I can change it beetween two options (photo below). Now I'll try to update BIOS Edited by, Acer Harvey.(Due to personal info provided)
  • sda1 is for sure usb, it shows the size of my pendrive (I tried with some of them). Now I have Ubuntu 18 LTS, but tried with 16 LTS and 19.04, so the problem is not with Ubuntu. Yeah, this might be a clue. I'll check this out! Anyway, Acer support is terrible. They told me my laptop is configured only for use with Windows…
  • Yes, I have done it before, but it didn't change anything... Any other ideas?
  • I left it unallocated. I made a mistake describing my steps :(
  • This grub64x.efi idea may work, but your solution assumes that I have already installed Linux. The problem is that the installer doesn't even see the HDD, so I can't install Linux the normal way. The only option is sda1, which is my USB. Should I follow step 10 anyway? Anyway, thanks for your reply!
