RHEL 6.2/Dell R710 UEFI install reboots to GRUB prompt
I recently installed RHEL 6.2 onto a brand-new Dell R710 with UEFI enabled. It sees the 4TB drive array fine, and installs fine...but when it attempts to reboot after the install, it returns to a GRUB prompt every time. I have tried booting to the grub.EFI file, which is installed in the expected place, but it returns me to GRUB each time. Is there a problem with RHEL 6.2 and UEFI, or is there something I need to do specifically? I have searched RHN from one end to another without result.

Hi Bill. Sorry you are having trouble with RHEL 6.2 on your UEFI box. The problem is described in this bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=719711
We also ran into it when we went to RHEL 6.2 for the Red Hat Enterprise Virtualization Hypervisor. This bug report describes a workaround, which includes booting to the BIOS and turning on Legacy Mode:

I believe the problem is being worked on since running in Legacy Mode is not a preferred long-term solution.
I also experienced this problem, but on an older Dell PowerEdge 2950 machine. My workaround was to install using the 6.1 iso and then upgrade to 6.2.
