Installation Failing

[FrankM]

A couple of days ago, I downloaded CentOS 6 and played around with it to get a feel of this OS.
I finished with what I wanted to learn and decided to go ahead and do a fresh install of CentOS 7.
Heres exactly what I did and where I am currently at:

1. Initialized my RAID drives and destroyed all data (I did this prior to installing CentOS 6 as well).
2. Placed my DVD with the latest version of CentOS 7 (Full) installed in the CD drive, naturally.
3. Selected from "Install CentOS 7, Test this media & install CentOS 7, and Troubleshooting >" and chose "Install CentOS 7"
4. Watch the screen blink a couple times and get shown this screen where it hangs http://i.imgur.com/R7N8EJ7.jpg
5. Decided to see what exactly was going on, so I went ahead and pressed tab and was shown this string of code at the bottom http://i.imgur.com/hHHjMBQ.jpg
6. I erased the parameter `quiet` and saw that it hangs at message saying `Probing EDD (edd=off to disable)....ok`
7. I went back to the install menu, and with "Install CentOS 7" highlighted I went ahead and pressed tab, removed the parameter `quiet` and added `edd=off`, which leaves me stuck hanging at this screen http://i.imgur.com/DJU7vlc.jpg

If theres any information I missed, let me know. Otherwise I appreciate any help I can get on this! Also sorry for not putting the images directly into this thread. I tried but the images were so large and took up so much screen space I couldn't

You have given no useful information about your hardware.
What exact model RAID controller do you have?
C7 dropped support for some older models.

You may also want to read the release notes to see if anything is applicable.

I thought I posted my hardware, had quite an exhausting day yesterday!
If anyone wants to know all my specs, just ask again.

I did actually ended up finding a solution this morning:
It turns out one of my RAID setups were stuck in "Consistency Check (CC)" for some reason, preventing me from writing to them.
After aborting the CC, I re-initialized the logical drives and ran another CC on them to check if anything got messed up from toying around with things.
Once that started going, the CC reported that it turns out my logical drives were inconsistent. My controller automatically repaired them for me and everything is A-OK now.

I guess due to the pending CC, the install couldn't actually write any files to my HD's, which I would assume make the install not function.

The usual fixes for this situation after research are usually just adding "edd=off" to the end of the install string as an extra parameter, or the "Disable Execute Bit (DEB)" is disabled, which takes a quick enable via the BIOS. Just in case anyone is having similar issues at the same hang screen!
