Question I have an hp 8200 mt but it is not compatible with my geforce gtx 1050ti. How can I solve this?

It would help if you mentioned what you mean by not compatible. It is a Sandy Bridge era PC, it should work with a 1050Ti.

If the BIOS does not recognize UEFI video for whatever reason, it should default to IGP until the OS boots and loads drivers for the GPU. If the BIOS fails to initialize the GPU and disables the IGP anyway, check if the BIOS has an option to force the IGP to enabled.
