Sorry to bother, I hope everything is fine.
Today I received my laptop, an Acer Aspire 5 (A515-44G-R9YM - with the Ryzen 7 4700U one). It came with Free DOS and I've tried to install Ubuntu on it. I did this with a live USB(downloaded Rufus and Ubuntu 20.4 iso from their official website) and everything went smooth during the whole installation process. However, after the install I was prompted to restart the laptop. I initiated the restart. During the boot up process, I could only see ACER's SPLASH image after which 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.
Since then, I've reinstalled Ubuntu 5 times! Each time, I got the same issue. I tried to install Ubuntu 18.04, and this time I got this output on my laptop screen :
dev/nvme0n1p2 clear .... blocks ....
To be honest, in the BIOS interface there weren't many options and settings to check. My USB stick got detected by the laptop(I know that for sure because I used 2 different ones) but not under its name, under "Linpus Linux" or 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 !
