Cant install Debian in a laptop

[arzgi]

I have fast boot still enabled on my system but I cannot say if it will cause problems...

Fast Boot is a UEFI option to skip some POST steps. It probably will only cause USB device booting to fail. Ultra Fast Boot will prevent you from booting to UEFI setup among other things.
Fast Startup is a Windows option like a hybrid hibernation mode. It will cause more problems with multi boot as any Win partitions will be mounted read-only in Linux after rebooting if you don't disable it.

My computers are so old, that they all have only bios, but fast boot has been option as long as I remember. Just like Sunrat said, it will only skip some tests at boot, after that it does nothging.

Are you installing from a DVD or a USB drive?

If a USB drive, exactly how did you create that? Be specific. Did it have an option to create
an UEFI-boot compatible drive?
