Virtual Machine won't start in Virtual Box

[Person_125]

Hi, so I have CentOS and Kali Linux as VMs on Virtual Box, they were working fine until I recently cleared the CMOS because of an issue with overclocking, since then the virtual machines won't start even though I have virtualization enabled in bios it shows this message: (VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED)), Result Code: E_FAIL (0x80004005). I tried looking the code up but all I found was the same fix which is to turn on virtualization in the bios.

 

Specs:

CPU: i5 3570K 

MOBO: Asus P8Z77-V (Bios version: 1805)

Ram: Kingston HyperX Fury 8GB DDR3 1600MHz CL10

 

Software info:

Virtual Box Version: 5.2.24

Windows 10 Pro 10.0.17134 Build 17134

 

Thanks in advance.

 

Update: I updated the bios to the latest version and everything worked.

Are you looking at the "Intel Virtualization Technology" options under CPU Configuration? If so, disable it, reboot, and re-enable it.

Thanks for replying, I noticed something weird while doing that which is that intel virtualization technology kept going back to disabled every time i reboot so I updated the bios to the latest version and it worked
