I had set an admin password in bios for security purposes, before setting it, I had disabled VT-x, UEFI booting, and booting from external media.
Unfortunately, I forgot the password, also it's impossible to reset it without having to replace the board
Now I need to use virtualization software which requires VT-x to be enabled, So there a way to enable VT-x without accessing the BIOS? . The method mentioned here didn't work (also, it's mentioned in one of the comments that the VT-x should be enabled in the first place for it to work)
While using windows HAXM check tool after following above method, it gave out an error - hardware acceleration needs to be enabled in the BIOS before committing the blunder, I was using emulators while VT-x was enabled, it was running smoothly.
P.S-Computer specs - Lenovo G470 , i3-2310M @ 2.1Ghz, 6gb RAM,windows 7 64bit model year 2010 please read this also it's impossible to reset it without having to replace the board
