Hi All,
I am trying to install 10.10 on my laptop, downloaded the CD a few times and run the install a few times but still get an error saying operating system cant be found. I have read many threads but all seem to refer to dual boot mine is a straight install on hard drive.
Laptop is ACER Aspire 1500
I have ensured that the Bios is set to boot from HDD, network boot is disabled, I have also tried reinstalling Grub following another thread Please help.
On Another Thread I read running the boot info script so I have done this and posted below.
