I have this error:
VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED).
I have tried Enabling PAE/NX, Disabling PAE/NX and neither worked.
Also, I have increased my RAM to the maximum before I get an error, 5309MB.
If I increase my ram higher I get Invalid Settings Detected. (not when I boot up, it says on the settings/system/motherboard.
It boots for a quarter second and gives me the error.
Any help appreciated, I have tried just about every online solution I could find but none seemed to change a thing.
OS: Windows 8 x86 Bit and I installed as Windows 8 x32 Bit so I'm not sure if thats a problem.
I am new to Virtual box myself. Faced the same issue and found the fix to be:
Though I do not have an x86 machine so cannot check for that.
Hope this helps.
