I've got a new Dell XPS 8500 last week. it came with 2TB hard drive and 12GB ram. I put in a SSD drive and try to do a fresh install of windows 8 using DVD supplied by Dell. UEFI is enabled in the BIOS. Boot secure mode is enabled. And legacy OPROM is disabled. It booted up the DVD and installation seemed fine. After it finished copying files it rebooted itself a few times. Then stops at a screen that complains windows installation failed, need to reinstall. tried it many times and the result is the same. Also tried a retail windows 8 pro DVD. same. The only way it will complete installation is to enable legacy OPROM but that means it won't be booting UEFI, which is what i want. Also tried loading the Intel Rapid Store AHCI drivers before starting installation but that didn't help. The BIOS version is the latest A09.
Dell tech support wants to replace the hard drive and motherboard. Does that sound right?
Did you disconnect the 2TB hard drive before you installed the OS? I'd switch it back to UEFI, then unplug the 2TB hard drive, and see if that would make a difference. If it installs properly I would reconnect the 2TB hard drive. Some forums have mentioned the need to disconnect the larger HD before installing OS on a SSD.
Why does Dell think you need a new HD and motherboard?
great, that's good to know. in my bios, when secure boot is enabled, UEFI automatically gets enabled and OPROM disabled. is your bios version A09?
maybe there is something wrong with my motherboard.
i dont have anything plugged in other than keyboard and mouse and monitor.
This is exactly the same thing I am dealing with.
First I tried creating system restore DVDs. Can't restore to a drive smaller than the original target.
OK, I have the disc and don't mind rebuilding. Same settings as you, UEFI on, OPROM disabled, A09. 2 TB drive unplugged. 250 GB SSD Samsung Extreme plugged in.
Install Win 8, reboot first time. Checks hardware, gets to 98%, reboots really quick.
Now every reboot after it tells me the install is borked.
Original 2TB drive is still available w/ Win 8 on it, installed from the factory, so it's not really too bad, except the performance of the drive could be a ton better (Windows Index 5.9, because of the HDD... stupid).
Order this system for dirt cheap because I thought it was upgradeable. Now I'm finding it's not as easy as I thought.
I copied my retail Windows 8 pro DVD to a USB drive and successfully installed to my 256gb MSATA drive with UEFI and secure boot enabled and other drives unplugged. They suggest that you have no volumes installed on the target drive before you start the install.
