My Sony VAIO machine already has windows 7 installed from the factory, I cleaned it up so my hard disk setup is:
*:System Reserved (350 MB) Primary NTFS
C:WINDOWS (50 GB) Primary NTFS
*:UBUNTU (32 GB) Primary ext4
*: (6 GB) Logical swap
D:PROGRAMS (30 GB) Logical NTFS
E:STORAGE (90 GB) Logical NTFS
After following many tutorials for using a LiveUSB to install Ubuntu, I am getting stuck at the very end with an error that GRUB was unable to install to /dev/sda. I also tried installing GRUB to the *:System Reserved partition, thinking that I could overwrite the windows bootloader there and GRUB would see my windows OS and include it in the menu. Error again.
I'm new to all this, trying to learn as I go. Something that struck me as odd was when using GParted from within LiveUSB, the hard disk in my laptop appears to be divided equally into sda (119 GB) and sdb (119 GB). It is a 256 GB solid state HDD with 238 GB of usable space. I can select sda and sdb from within GParted, and they each show 119 GB of unallocated space. The selection that reveals my partitions is /dev/mapper... and it shows the primary partitions individually but groups the logical ones into an extended partition.
Anybody got any ideas? I'm going to try and use boot-repair from within LiveUSB, and maybe execute some grub-install command line scripts and see what that does. I have no idea what the problem might be though, just shooting in the dark.
Thanks for your responses! I'm headed to work but will check back later.
