Why does installer go into blank screen and shows no progress while doing installation of Red Hat Enterprise Linux 7 using UEFI on Cisco UCS Hardware?
Issue
- Installing Red Hat Enterprise Linux 7 using UEFI boot mode enabled on Cisco UCS hardware.
- As soon as the splash screen appears, and once an Enter is Hit, the installer goes into blank screen and never returns back. No further progress appears.
- Once UEFI is disabled, Legacy BIOS Boot works fine.
- Red Hat Enterprise Linux 6 works as expected, UEFI boot as well as Legacy BIOS boot works too.
- Why does this happen? Isn't UEFI boot on Cisco UCS supported or incompatible?
Environment
- Red Hat Enterprise Linux 7
- UEFI boot
- Cisco UCS Servers
