TC-886-ER11 legacy boot
Hi All,
I've got a client who went out and bought two TC-886-ER11 desktop machines with the hope that they could upgrade their current hardware to newer systems (they're currently running old ThinkCentres). They have a ton of quickbooks and work order data that they need to keep in tact, and I'm trying to avoid building the new machines from the ground up.
So I've imaged the drives from the Thinkcentres (as backups), with the idea of popping them in the new Acers and prepping them that way. I've done this a hundred times with different machines and no issues. Problem is, these OS drives are MBR. The BIOS (v. R01-A3) has an option to Launch CSM but this is greyed out. I've done everything suggested in other threads including the obvious disabling of secure boot (which can be done without a supervisor password being created), I also created a supervisor password to see if that would enable the option. I've tried RST with Optane, AHCI, literally every single thing I can think of, but I can never enable the Launch CSM option.
What kind of system doesn't offer the ability to boot to legacy, but sticks the **** option in there! Anyone have an idea how to get legacy boot enabled? Or is this a hard stop because this BIOS doesn't offer the option at all?
