this thread reports same hang at Dell logo and confirms if one turns off secure boot in XPS 8930, it will boot with RX 6600XT. if you extrapolate it to 8900 and RX 6600, it is likely same solution. [URL]
Hi! I recently bought a new Rx 6600, but when I switched out the original Gt 730 for the new card, I am getting stuck at the Dell logo. I checked to make sure the gpu is sitting properly and the 6+2 pin is as well. When the pc starts, the gpu fan does work so its getting power but stuck on dell logo pressing F2 or F12 doesnt do anything. I upgraded to the latest BIOS and I uninstalled nvidia drivers beforehand. Am I doing anything wrong, what are potential causes? Thank you in advance!
XPS 8910, installed RX 6600, no boot?
