I've been working on my dell-latitude E6420 with dual-boot windows 7 and ubuntu 15.10.
I've recently installed windows 10 and after I installed it, ubuntu disappeared.
After the installation the computer booted to "grub rescue". So, after some looking around I burned "Boot Repair Disk" on a usb drive and took the "recommended repair" option.
After running the "recommended repair" the computer boots into windows 10 (without giving me the grub menu before).
In the past I re-installed ubuntu on the same partition without formatting and I actually did not lose my files, so I thought I'd try that.
So I booted from the installation usb, and started the installation, picking the following options:
Install ubuntu -> continue (has at least 7 giga, not connected to the internet, didn't mark 3rd party software) -> something else -> .... And now I get to the problem: The next screen (Installation Type) has the following table: Installation type screen
sda1 is obviously the windows installation.
I think sda2 use to be for the grub and if I'm not mistaken, is suppose to be of type "swap".
sda5 is a partition I made so that I can have access to files also from windows and also from ubuntu.
sda4 is a "format all of your data and go back to factory settings" drive I've got the computer with.
and finally - "free space" is where ubuntu was installed and I have no longer access to...
I tried picking "free space" for the installation, but then it marks the "format?" checkbox, which I definitely don't want to do!! (I can't uncheck the checkbox manually).
I've also tryed (several times) to pick "try ubuntu" and get access to my files from there, so that I can back them up and then make a clean installation, but the only partitions I see when "trying ubuntu" are the 65gb (sda5) and OSDisk (sda1).
That's it. So, if any one can help me either getting access to my files or re-installing ubuntu without formatting the partition, I'd appreciate it a lot!!!!
