Got a MacBook Pro, 13 inch, 500gb Hard Drive, 4gb memory. Made a massive screw up on dual install, luckily had already transferred files to Ubuntu one. Ok, trying to install from USB, boots from that perfectly. Currently using the "Try Ubuntu without installation". Looking at GParted:

/dev/sda1: fat32.   No mount point.          Size: 487Mb,    Used: 4.27Mb.   Flags: boot
/dev/sda2: ext2.    No mount point.          Size: 244Mb,    Used: 51.69Mb.  No Flags
/dev/sda3: lvm2 pv. Mount point: ubuntu-vg   Size: 465.05Gb, Used: 465.01Gb. Flags: lvm
Unallocated: Size: 1.02Mb

NB: This was after an attempted install using LVM(?) NB 2: I have no idea what any of these things mean :P I do physics (undergraduate), not computer science!

I keep seeing the install programme through. I have tried doing the install from the trial desktop, doing the install from boot, and doing the install with OEM.

Each time, whenever I restart (as required by installation), it just asks me whether I want to install (black screen with list of boot options). Never gives me the option to boot from currently installed Ubuntu.

I have even tried to take out USB before the restart and it comes up with a flashing file symbol with a magnifying glass in the middle!

I would recommend not using LVM unless you really need it and you know what you are doing - I don't think it is the default option from memory. If you try installing from boot and choose to format and use the entire drive (don't use LVM), then remove the USB for the reboot, do you still get the same error icon (which is the Mac telling you it can't find a system folder to boot from)?

Hey, Initially I tried without LVM. and same problems occured. I have decided to order the CD to see if that works any better. Hoping it will. From the information I read beforehand trying to install from USB is problematic so hopefully this will work! :) Thanks very much :) –  Alex Dec 18 '13 at 21:52
