Hi Everyone!

Solved the same issue by booting a rescue mode and then creating new partition table on disks with fdisk. I think it cleared previous tables made by onboard RAID controller. 

Regards!

Thanks Michael for your workaround - worked for me too :)

it works well for rhel7.4 RC kernel , 

thanks

Issues like this are usually caused by some preexisting data on the drives, but I cannot tell what the specifics are because no logs were attached and beaker links are not working for me.

If anyone sees this problem and can attach the logs I will be happy to take a look.

I have the same problem, and I am willing to provide more data as instructed to solve this problem, because I was not able to solve it.
I have a macbook late 2009 with a 500 GB hard drive. I want to dual boot it, and I want to boot RHEL with EFI, definitely, no bios/MBR, so my drive os formatted with GPT partition table format. I have a 200MB EFI FAT partition, and a 50GB HFS+ partition to host macOS. I need to have an physical volume and use the first 200MB EFI partition as /boot since macOS doesn't use it anyway(it writes all of the boot configuration on its internal firmware memory, which partition it will boot, and the kernel is on the mac / partition) so my plan makes totally sense. All of my partitions will be on logical volumes, and I like this I plan to have as few partitions as possible, and use the flexibility of LVM to support my needs on linux.

So, I have tried many times, many different configurations, I just can't wipe the 50GB HFS+ partition because I need to have macOS on this macbook, for eventual needs, the rest I wiped even the macOS recovery partition. My GPT is not hybrid. I was wondering if I was really being able to boot the RHEL 7 installation disc on EFI mode. I have a RHEL 7.3 DVD and  I downloaded the most recent RHEL 7.4 and dd the iso image to a usb disk, and both have the same issue.

The bug always happens on the "INSTALLATION DESTINATION" screen. I tried many different configurations, on my setup, this is totally broken. After many trial an error, I found out that just entering the "INSTALLATION DESTINATION" screen, and not selecting or changing anything, does trigger the problem:

"An unknown error has occurred

This program has encountered an unknown error. You may
report the bug below or quit the program."


I used the report bug button and went all the way through it.
I think all the files got attached.
They are in http://api.access.redhat.com/rs/cases/01907229

Please reopen the bug ask for more information if needed.

Thanks in advance.

Just adding my occurrence of the above issue on my D30. 

I had the above error  on rhel 7.4 iso.
Tried  rhel 6.7 iso and got  "contains BIOS RAID metadata" and "Ignoring disk" message.
Tried removing and creating partions  with fdisk did not work for me. 
Then used dmraid -r -E /dev/sd<x>  to remove the metadata.

Now installing rhel 7.4 is working.

dmraid -r -E /dev/sd<x> 

works for me, thanks @vlovejoy!

first boot in rescue mode then run the command
