Changing boot from legacy to uefi

[fr.mueller]

Hello together,

i try to change the boot order from legacy to uefi on a vmware esxi that is booting from SAN.

First try, just change the boot order to uefi. Server boots into bios

Second try, change th uefi boot parameter to the following value

Boot Loader Name: BOOTX64.EFI

Boot Loader Path: \EFI\Boot\

Same problem. Boot into bios.

Third try, update esxi while uefi is configured. Booting from cd, updating esxi. booting normal. Same issue. Booting into bios.

What else can i try to configure uefi boot? 

Thanks for any hints

hi Frank

1 Which ESXi version?

2 Which server model & CPU? 

3 UCSM (domain connected) or CIMC standalone?

4 Service Profile managed by UCS Manager or UCS Central?

CSCuh13333 No boot item added in F6 boot menu for the new installed esxi OS contains commands to manually boot into ESXi if you boot into UEFI shell. E.g. if this works it may mean an issue with the boot entry. 

If you have not found/followed Troubleshooting Boot From San Installation - Cisco Community yet, please have a look.

ESXi Version8

It is an old B200 M3 that i am using for testing before changing production

UCSM connected but not UCS Central

I don't think you are going to get an M3 server to boot ESXi 8. I don't think the CPU's are compatible. I know my M5's support ESXi 8. I am trying to remember if M4's support ESXi 8, but I don't recall. I upgrade mine a couple years ago.
