This is my issue.
I just got a brand new laptop (Windows 8 Samsung).
This does not have a cd drive and I wanted to do a dual boot with Windows and Ubuntu.
I did a "install from flash drive approach" and I choose "Install alongside windows 8" option.
It got installed successfully but the ubuntu was very laggy and slow.
Since I like Ubuntu much I decided to erase my windows completely and install Ubuntu as the only OS which now I am unable to.
Because for some reason
My flash drive does not appear in the list of boot options
It says something like
"Option 1 : Windows xxxxx"
"Option 2 ubuntu 12029mb etc"
But when I choose Ubuntu it takes me to the GRUB screen back and I am unable to reinstall Ubuntu.
Is there some way I can make this bootable flash drive to come back again as one of the bootable options so that I can wipe everything and keep ubuntu as the only OS ?
