De Apenas erro Lenovo UEFI Gosta do Windows e do RHEL :
It looks like Lenovo only knows of Windows and RHEL where their Thinkcentre M92p desktop is concerned. While investigating UEFI boot issues, Matthew Garrett found the PC's firmware actually checks the descriptive string for the operating system, and will prevent unlisted operating systems from booting.
Garrett writes:
Every UEFI boot entry has a descriptive string. This is used by the firmware when it's presenting a menu to users - instead of "Hard drive 0" and "USB drive 3", the firmware can list "Windows Boot Manager" and "Fedora Linux". There's no reason at all for the firmware to be parsing these strings. ... there is a function that compares the descriptive string against "Windows Boot Manager" and appears to return an error if it doesn't match. What's stranger is that it also checks for "Red Hat Enterprise Linux" and lets that one work as well. ... This is, obviously, bizarre. A vendor appears to have actually written additional code to check whether an OS claims to be Windows before it'll let it boot. Someone then presumably tested booting RHEL on it and discovered that it didn't work. Rather than take out that check, they then addded another check to let RHEL boot as well.
Portanto, parece que a Lenovo não permitirá a instalação do Solaris neste modelo.
