[Pre-Install] hardware or media issue trying to install 26.10?

[suplero]

tried installing 26.10 five times today, and every time the installer would start to a full screen (not a fan at all of that full screen installer without any window controls) and it would be black. then after a minute or so, the entire system would do a complete hang, requiring either a power button reset or total power down.

tried with multiple drives, thinking maybe the formatting was an issues, so brand new drive didn't work, ssd didn't work, ssd with windows didn't work. every time the system would hang without error at the full screen black screen.

after 26.10 i tried installing 26.04, and that installer started correctly, but the first install failed, but the second install seemed to finish without issue. the failures don't seem sporadic enough to be a random hardware issue, and 24.04 works on that machine, as does windows.

same here

but in my case, the installation somehow took a while, and then failed at 98%

You didn't mention it, but I wonder if you checked the downloaded ISO file.

My process is:

1. Download ISO
2. Verify checksum
3. Copy ISO to Ventoy USB stick
4. Verfiy checksum again.
5. Boot Ventoy

Not helpful, but I just installed 26.10 with no issues. Boot to a verified ISO, select "Try..." rather than "Install..." then run the installer from the desktop icon. Maybe you'll have better luck.
