Hi All,

1. Made sure Bios set to boot from UEFI USB.
2. Using Shift+O to add boot options in the following order seemed to be required: tscSyncSkip=TRUE timerForceTSC=TRUE
3. Now installer for ESXi 8.0.2 working and installed ESXi to an SSD.
4. Once ESXi 8.0.2 installed and running.
5. SSH to console and add the above settings as shared by the posts to the kernelopt= line. For example my kernelopt finally looks like this -
6. kernelopt=autoPartition=FALSE tscSyncSkip=TRUE timerForceTSC=TRUE
7. Reboot ESXi through the UI.
8. ESXi 8.0.2 came up successfully.

Thank you all for your support.
Made it in the end.
MJ
