Err, my bad. I know of a fix to the "invisible grub", but it requires booting into Ubuntu. I thought the links were relevant. Anyhow, I'll look up your issue again. Don't worry and kindly be patient.
I'm not a great UNIX expert, but no-one else seems to be answering, so I'll try to help.I'm new to Linux installation, Why we need to create a swap partition and what use of it? I'm searching for this answer but I couldn't find it.
Can somebody let me know if my Hard disk is 1TB and 8GB Ram what SWAP size should be given.
Thanks advance for your answers.
