I have lenovo u510 with windows 8. This ultrabook has 24GB SSD and I tried to install Ubuntu 12.04.3 in it. I changed bios from UEFI to legacy and I used a LiveDVD. I created a 17GB partition when I was in windows from this SSD and I tried both manualy or with the "install alongside" but was allways without success because bootloader install failed and was unable to install GRUB. I tried also to use the "recommended repair" from Boot-Repair but it says that my laptop can only with UEFI boot. I changed it but the same thing happens my laptop boot in windows 8.
