Shifting from legacy to uefi without reinstall

[babi1987]

Hi
I clean installed Win 10 FCU in legacy mode. The system has has a GTX1050TI. Can I change to UEFI mode in BIOS without reinstalling windows again?

I think you can't, because the partition structure is different. You can only convert your hdd from mbr to gpt with 3rd party software but not the legacy to uefi boot because uefi add 3 more partition than mbr that only add one "system reserved" partition.
Just reinstall windows in uefi mode

Can I reinstall IN uefi mode with the graphics card installed on PC?

Graphic card seems not to be the problem when installing windows. If it can't show any display, try switch your display cable to onboard connector
