please help me. Seems to have problem with Lenovo H420 bios uefi/legacy.
Bought a new video card RX 480, PSU is 580 W and it is enough, tested on other system, card is working.
Rx480 has bios switch but nothing happens, not booting.
I read from other similar issues to change uefi/legacy settings, but in bios this Lenovo has no option.
To upgrade bios Lenovo has no upgrade.
What else can i do? Thanks for help.

Newer generation AMD graphics cards have a history of being not backward compatible with older Lenovo systems. Other than ensuring you are at the latest BIOS level (and thereby supporting the newest hardware), there is nothing that can be done.
I did search the PassMark system benchmarks, and found the following baselines uploaded:
H420: HD 7750, Gtx 550 Ti, 650
K410: HD 7850, Gtx 550 Ti, 650 Ti, 660, 750 Ti
