Hi Folks Having a bit of a brain teaser at the moment. I have been running Ubuntu 12.04 on all my machines but out of curiosity I tried putting 13.10 on my Thinkpad X120e, it has a 250gig SDD which ran 12.04 just fine. I looked at the partitions and saw it had an efi boot partition before I tried the 13.10 from a thumb drive. I went through the standard install procedure till I hit "install" when it told me to go back and put an efi partition of at least 35megs right at the beginning, that meant starting all over so I did. to cut a long story short after three attempts I decided to use the latest gparted IOS and partition before installing so as to make sure the efi was correctly placed. This install I formatted the premade partitions as needed and it did not tell me to go back so I thought I was on to a good thing but NO. So whats happening is on reboot after installing the hard drive cannot be found whichever way I installed. I did go into the BIOS and make sure UEFI was enabled in both USB and SATA locations, also I tried a DVD install as person on a Ubuntu forum in the UK suggested that would work, the laptop is from Oct 2012 and the SDD is less than 6 months old so all hardware is current. I hope I have provided enough information for someone to perhaps make a suggestion or two. Thanks in advance Eric Brackenbury PS: 13.10 works fine on this machine installed on a spinning disc -- http://www.tumblr.com/blog/therecycledteenager *“It is possible to escape death by perching on your enemy's eyelashes; it means you are so close that he cannot see you.” – Ninja Kawakami*
