I got into a bind trying to install Windows and Ubuntu 14. I installed windows and then I used Ubuntu as a live CD and it couldn't see the Windows partition. I had some trouble but I was able to reinstall windows after formatting the drive, or that is, after Windows redid the file system. This time Ubuntu could see the partitions. Because of some other stuff someone advised me to use a command line to delete the first 10 megabytes of the disk. I did that and then he wasn't sure what for me to do next. Gparted no longer sees the partitions but the disk utility does. Once I removed the live CD the system now won't boot at all. So I'm annoyed and now I'm not sure how to format the drive and start over again.
mkfs -t ntfs
Maybe that is what I need to do using the LiveCD again but I'm not sure. Please advise and thanks very much.
