I've recently bought an Ultrabook with "Hybrid" HDD (500 GB) + SSD (32 GB) (Intel caching technology) that came with Windows 8 pre-installed in UEFI mode.
I wanted to dual-boot it with Ubuntu 13.04 x64, so I did the following:
- Disabled everything Intel-related on the BIOS and on Windows 8 (including Intel RST's RAID);
- Shrank Windows 8's partition;
- Installed Ubuntu's root (/) on the SSD, /home/ and swap on the HDD.
It worked fine like that. GRUB loaded on startup and displayed a list with a lot of *.efi files, two "ubuntu" entries, UEFI loader (something like that, I'm not sure) and Windows 8 UEFI. When I chose the first "ubuntu", it loaded up ubuntu, the second one loaded Windows 8, and "Windows 8 UEFI" entry didn't load.
I also wanted to re-enable the caching technology for Windows 8, since it's a nice feature. So, I went to the BIOS menu and set-up the Intel RST RAID. Now, I can't boot any system. Nothing shows up when I turn the computer on. It just displays a message telling me to install an operational system. I think the RAID screwed the UEFI boot-loaders (or something like that, I'm pretty newbie as you can tell).
So, my questions would be:
- Is my problem the boot manager?
- If it is, could I install rEFInd or GRUB to fix it? How?
Thank you for your time :)
