Hello guys, sorry to bother, I hope everything is fine.
Today just arrived Aspire 5 (the A515-44G-R9YM Ryzen 7 4700U one) laptop and I've tried to install Ubuntu on it. I've searched for my best USB stick and got to work (put the Ubuntu installer on it through Rufus soft). I've installed it and everything was ok during it. The bad part comes when they asked me to restart the laptop. After it opened again, there appeared on the screen the ACER name, and after that I got a black screen and on the left top corner there was a little underline sign that kept flashing every 0.5 seconds. I've waited, and waited, and waited, and nothing happened. I've reinstalled it 5 times again and again and I got the same issue. To be honest, in the BIOS interface there weren't many options and settings to check. My USB stick got detected by the laptop but not under its name, under "Lipus ....something". And there was no setting such as Legacy USB support to enable and help me out or something.
To be honest, it's my first time installing Linux on my system (I've been a Windows user for over 11 years now), so it's most likely that I've missed something.
Does anyone know what I can do ? Thank you all for your time !
