Hello all,
Trying to install 10.10 on a Dell 6220. It's on the compatibility list, and I have created a clover USB install. The installer successfully boots on other systems, but on the Dell I get a 'Selected Boot Device Failed."
The BIOS is the latest A13. In the BIOS I've reset everything to default and set AHCI as recommended. I'm using the Legacy instead of UEFI (also recommended).
Any ideas what I am doing wrong? Thanks!
