My laptop came installed with wiwndows 8 in UEFI boot. I had installed Debian (in legacy boot mode) a while back. It all worked fine except for the need to switch boot modes every time I changed my setup.
Today I decided that Ubuntu was better suited for me and tried to replace my Debian/windows dual boot with a Ubuntu/windows dual boot.
I set up an USB drive with the right ISO and started the process. I booted on the USB drive (in EFI mode) and started the install. When I was asked if I wanted to install alongside Debian or instead of Debian I chose the later since I thought this would leave windows alone. I was SO WRONG! It formatted my whole hard drive and now I only have the brand new Ubuntu partition. I insist that Debian and Windows were both working fine. I know there is no way back and I should have been more careful, so my question is:
Shouldn't there have been mention of windows in this (oh so fatidic) page of the assistant?
I would almost have expected the assistant to detect windows and not Debian since it was setup in legacy and the USB drive booted on UEFI but the reverse seems to have happened.
Anyway I learned my lesson: no more letting an assistant "manage" my partitions...
