Installing 16.04 from .iso installed on hard disk partition

Support & Help Requests
1

Ok, my DVD is dead, and it’s proprietary so it’ll take awhile to replace, my system doesn’t do USB boot, and I want to upgrade to 16.04.

I have other computers but this is my workhorse.

Unetbootin won’t burn the .iso to my sda7 partition…How can I burn the install image to my sda7 partition and have it show up on my grub menu so I can boot into it and upgrade my 14.04 to 16.04?

I used to do this with Windows XP every 6 months when it corrupted and I had to format and reinstall, I had XP install in it’s own partition. I did that until I switched to Ubuntu Linux in '09.

Any thoughts?

If you already have Linux installed with grub2 then this is easy. Just copy the ISO file (don’t extract it) to the sda7 partition. Then add a new entry to your grub2 to use the loopback feature to boot the ISO file.

This https://help.ubuntu.com/community/Grub2/ISOBoot makes it sound a lot more complicated than it is.

That’s how I would do a fresh install. Don’t know about preserving any settings from the previous install.

Thanks, I’ll study on this. I’ll see if I can do this without screwing it all up. I may have to follow up with you:slight_smile:
