ArcaOS 5.1.1 can't install on Acer Aspire.
« on: November 15, 2025, 03:23:59 pm »
Hi,

Changed the UEFI and disable secure boot.
Acer starts, boots from USB install stick.
When choosing to install on harddisk and start the installer it gives an error that "config.sys is not found on B:"
It doesn't matter if you choose default installation or own menu.
Any idea's?

Perhaps try a different stick. Some of the cheap ones don't work very well and they do wear out. It's worth using a quality stick.

Hello Adrian.

Like Dave said, I will also try a different USB Flash stick drive, just in case.

Are you installing ArcaOS 5.1.1 ?

Just in case, This year at Warpstock there was a good presentation about the installation logs and install diagnostics.

Plus there are documentation here:

I would prefer to install the UEFI version to have DOS and Win-OS2 sessions working if you manage to advance with the install procedure.
