Hi,

yesterday i put an ssd on my Dell E5430, after installing windows 7 the computer gave me the error "Invalid partition table", so i decided to go in the one time boot menu and go manually inside windows, and it worked, later i decided to solve that error, so i changed boot order, now the computer boots up to the Dell logo, and later a black screen with a white blinking cursor appears, i tried to get in the one time boot menu (f12) and that screen appears, tried to go in the bios and that screen appears, i tried to diagnose the computer too (with fn + power button) but the computer does nothing, that screen appears again.

I tried to start the computer with the wifi card and the hdd removed, but nothing even with the hdd removed that back screen appears again. the only way to turn off the computer is by holding the power button, ctrl + alt + canc does not work.

This is not the first time that my (and not only mine) laptop has bios isues, later solved with a bios update.

The laptop has the latest bios firmware (9 Jan 2019).

I have a video that can demonstrate the issue, i will post it only if needed.

Thanks

P.S. this is the short story of yesterday, if you whant the long one ask me...
